Steady demand balanced by consistent supply
Global tilapia production is expected to almost double from 4.3 million tonnes per year in 2010 to 7.3 million tonnes a year in 2030
tilapia will likely be one of the main contributors to the fastest growth in global aquaculture aside from carp and catfish
Asia remains the main driver of tilapia production with China in the lead
Supplies from Latin America are also expected to increase though a drought in the Santa Fe do Sul region in Brazil has resulted in a 30% drop in tilapia production
The region is one of the largest producers of tilapia with an annual production of about 22 000 tonnes annually
global exports of tilapia during the first half of 2014 reached approximately 200 000 tonnes
Supplies were primarily from China in the frozen form with the largest market being the USA
imports increased to other markets as well as to new markets
total Chinese exports of frozen tilapia increased marginally (+1.3%) compared with the same period in 2013
Although frozen fillets account for the largest share
exports of this category declined by about 1%
exports of whole frozen and breaded tilapia showed growth of 2.8% and 3.9% respectively
A significant share of the whole frozen category continue to be directed to African markets which are paying better prices due to growing demand
Substantial exports are also taking place to Iran and other Middle Eastern countries
Exports also increased to Latin American countries namely Costa Rica
Tilapia continues to be one of the most popular seafood items in the USA
which was confirmed by the steady growth in imports (+5%) during the first half of 2014 compared with the same period last year.
Fresh tilapia imports into the USA during the first half of the year slipped down 4.3% from the same period last year
while the import value strengthened marginally (0.4%)
the main supplier of fresh tilapia to the USA increased its exports significantly by 39%
taking advantage of lower supplies from producers who moved from farming tilapia to shrimp
imports of frozen tilapia (whole and fillet) during the first half of 2014 were up 6.6% compared with the same time period a year ago
Whole frozen tilapia imports declined by 10% from China as it diverted more exports to the African markets
Seattle US-based Tai Foong USA is the first company in the USA to source and sell ASC certified tilapia under its “Northern Chef” brand
The products have been on sale since mid-May this year across the country in Sprouts Farmers Market and Ingles Markets
The company reports that the ASC certified tilapia has become the number one seller in their “Northern Chef” finfish line of products due its high quality
clean taste and responsibly farmed attributes.
increased by 13.3% with China maintaining its position as the lead supplier
imports are also increasingly coming from other sources.
Continuing the growth from the first quarter of 2014
frozen tilapia fillet imports into the EU-28 demonstrated a 6.7% increase from the same period in 2013
imports from this source dropped by 16.2% from a year ago
Taiwan Province of China and Costa Rica took advantage of China’s drop and established a stronger presence in the market place during the first half of the year
Viet Nam and Indonesia took an 18% and 14% share of the market compared with 4.4% and 11% during the same period last year
The growth in demand has been attributed to the availability of ASC certified products in the market
the tilapia industry started the year strongly
compensating for the international drop in prices
with Honduras and Costa Rica as main suppliers of fresh tilapia fillets to the USA
supplying approximately 5 300 tonnes and 2 900 tonnes respectively during the first half of 2014
Exports from Ecuador declined by 56% compared with the same period in 2013 as many farmers moved from farming tilapia to shrimp
Further development in value added products is expected
opening a wider range of options for the final consumer
much of the tilapia consumption in the region has opened opportunities for markets other than for export
Incentives to develop small and medium scale production projects aim to meet the demand of the domestic market and substitute or complement other species traditionally consumed
consumers in Latin America continue focusing more on price than on quality
small and medium scale producers have not established measures that would guarantee product quality for the export market
which is currently dominated by large producers
in Honduras wholesale prices vary between USD 1.43 and USD 2.00 and in Guatemala between USD 1.15 and USD 1.41 for whole tilapia
the second largest exporter of frozen tilapia fillets behind China
supplied 22% more tilapia to the international market in the first half of 2014 compared with the same time period in 2013
Taiwan PC exported 11 391 tonnes of whole frozen tilapia during the first half of 2014
Taiwan PC supplied close to 53% of frozen tilapia (mostly whole products) to the USA
The Middle East is also an important market for Taiwanese tilapia.
Tilapia imports into Asian countries are rather small as most of the local production enters the domestic markets
Republic of Korea and Japan totaled approximately 2 000 tonnes according to national statistics
Imports into Japan mainly constituted of izumidai quality (sashimi) tilapia
Japan also has imports from the Philippines
which is mostly directed to the Filipino community in Japan. Recently
frozen tilapia imports are also being shipped into new markets namely Iran
Ghana’s ban on imports of tilapia aims to build a stronger domestic production sector
as the move is thought to spur growth in local aquaculture
The issues Ghana is currently facing can partially attributed to its high reliance on imported products
According to the Minister of Fisheries and Aquaculture
the ban would create about 50 000 jobs in the aquaculture sector of the economy
which is aiming to provide livelihood opportunities to young unemployed persons
Whether the import ban will result in a viable domestic sector able to offer products competitive with other sources of protein remains to be seen
The tilapia market will remain firm with steady demand leading to stronger prices in producing countries’ domestic markets
As long as tilapia prices stay competitive
new markets will possibly strengthen and develop further

It wasn’t all that long ago that Maria Lepore Araujo thought she would be content to stick close to home
a small city of a little more that 32,000 residents — and a popular tourist destination — located about 650 kilometres from Sao Paulo in Sao Paolo State
She joined her local Rotary’s Interact Club at the high school she was attending and later found out about the student exchange program
Rotary Interact Clubs — there is one in Pelham at E.L
Crossley Secondary School — help youth ages 13 to 18 develop leadership skills through service to the community
The Rotary Youth Exchange is an international exchange program open to youth from 15 to 18 years old who wish to spend up to a year living with host families abroad and attending school in a different country
I didn't think about it,” Lepore Araujo
I’ll go live in my city and just that
but now I want to know about other countries.”
“I think maybe the snow,” she said
She got her first taste of the white stuff on a trip to Michigan last weekend
the “magic” might be wearing off
Lepore Araujo’s words trailed off as she began to laugh
It has been an adjustment for Lepore Araujo
She had to brush up on her English quickly before starting Grade 11 at Crossley
there was also the matter of just when she would attend school
Her classes also started – and finished – earlier
and we [go home] at 12:30,” she said
there are plenty of challenges beyond simply being away from home
It can be physically and emotionally taxing
the youth exchange officer for the Rotary Club of Fonthill
“It would be not just a matter of school,” he said
The process for kids coming in on exchange is they are trying to translate all day long
But her stay in hasn’t been all about school and work for Lepore Araujo
There has been some time for play as her host family have been showing her around Niagara and beyond
“They always are trying to do something with me,” she said
I went to St Catharines first to see a hockey game
Seeing the Niagara IceDogs in action was the first time she had seen a hockey game and she enjoyed the experience
“[My host family] explained it a little bit but for me
said exchange students from various clubs in District 7090
which takes in southern Ontario and Western New York State
“All the exchange kids in our district somewhat routinely get together for weekend events sponsored by the district,” Taylor said
“They have a weekend in Buffalo coming up and on Saturday all of them are going to get to go to the Buffalo Sabers game.”
He added that Maria has seen an interesting twist in her Rotary journey
“She had been so involved and engaged in Interact and the activities that they’ve done
that she actually inspired her mother to become a member of Rotary,” Taylor said
it’s the Rotary member who gets someone involved in the youth exchange but this time
it's the youth exchange student who kicked her mom into gear to go to the club itself.”
Now she and her mom have something they can share
and like having ideas and she really liked to help
Lepore Araujo will be in Pelham until the end of the school year next June

Is the base-engine Santa Fe better than its competition
Zach GaleWriterAug 09
It feels like we blinked and the sub-$35,000 slice of the midsize SUV class shrunk; the Ford Edge and Honda Passport now start just under $40,000
the Hyundai starts around $30,000 before accounting for any potential dealer markups
We recently spent time with a 2022 Hyundai Santa Fe SEL 2.5 to see just how well the turbo-less SUV performs against affordable competition like the Subaru Outback
does the midsize Santa Fe feel like a penalty box
and the 2022 Santa Fe's idle has just a touch of vibration and harshness
but it's acceptable—and the hushed Santa Fe Hybrid isn't for everyone
Driven in its natural habitat—on suburban roads and on the highway—and the Santa Fe 2.5 is surprisingly responsive
the transmission makes the most of the engine's limited power so that with a little planning ahead
but it's a small price to pay for this decent compromise of features-per-dollar value
That's especially true considering how unrefined we've found the Santa Fe with its turbocharged 2.5-liter engine and eight-speed dual-clutch automatic
Where that Subaru falls far short against the Hyundai is in perceived (and actual) interior space
This is where the Hyundai's shortcomings
such as the busy front design and only so-so fuel economy
There's tons of front and rear legroom
and rear passengers should appreciate the mostly flat floor
the Santa Fe's 36.3 cubic feet of cargo space behind the rear seats is outdone by the smaller Tucson's 38.7 cubic feet
Both Hyundais outdo the Subaru's 32.6 cubic feet
but all these figures are good; it's certainly better than the otherwise appealing Toyota Venza
whose cargo floor is a bit high and can only hold 28.8 cubic feet of stuff
The 2022 and 2023 Santa Fe also have extra storage compartments you may not notice on a test drive but should become useful in everyday life
The first is hidden under the center stack of controls and made possible by the push-button PRND controls
The second is a small Toyota Highlander-like nook in front of the front passenger
One of the most significant changes from the 2022 to 2023 Santa Fe at the SEL trim might be the addition of acoustically laminated front side glass
the feature won't make the mixed interior quality any better
but it will make it a slightly quieter place to spend time
Also new for the 2023 Santa Fe SEL versus our 2022 test SUV is a leather-wrapped steering wheel
and a larger 10.3-inch unit (replacing an 8.0-inch unit)
We had no issues with the smaller 8.0-inch setup
which never felt like a punishment for lower trims thanks to its already decent size and positioning at the top of the dash for optimal visibility
All of this extra standard content at the SEL trim level will come at a price
but the 2023 Hyundai Santa Fe will undoubtedly be priced competitively with the value-priced Subaru Outback and other midsize SUVs
The 2022 and 2023 Hyundai Santa Fe remain good though not great options in the midsize SUV segment
Our biggest disappointment with the base-engine model we drive isn't its satisfactory performance but its fuel economy
which is barely better than the more powerful turbo (22-25/25-28 mpg city/highway for the 2.5 versus 21-22/28 on the 2.5 turbo)

The COVID-19 pandemic has been marked by novel viral variants
is implicated in SARS-CoV-2's ongoing evolution
known for evading antibody-mediated immunity
exhibits higher transmissibility without increased disease severity
We investigated the prevalence and genomic features of XBB in SARS-CoV-2-positive cases in Rio Grande do Sul (RS)
We sequenced 357 samples from epidemiological weeks (EW) 47/2022 to 17/2023
and included 389 publicly available sequences
Clinical and epidemiological data were obtained from DATASUS
and SIVEP GRIPE (data recording systems of the Brazilian Ministry of Health)
143 were classified as XBB and 586 were other Omicron lineages
97.7% of XBB-infected patients successfully recovered from the infection
Even after receiving three vaccine doses and having been previously infected
59.5% of the patients experienced reinfection with XBB
the interval between their XBB infection and the last vaccine dose exceeded one year
potentially leading to a decline in antibody levels
we identified 90 mutations in RS circulating XBB
notably in the Spike protein region associated with immune resistance
This study provides insights into the dynamics and impact of a recombinant variant becoming predominant for the first time in the state
Continued surveillance of SARS-CoV-2 genomic evolution is crucial for effective public health management
continuous surveillance and monitoring are essential
we investigate the prevalence and genomic characteristics of the first recombinant variant that predominated in SARS-CoV-2-positive cases in the RS state
We compiled 357 samples positive for SARS-CoV-2 that were sequenced
as well as 389 publicly available sequences collected from November 20
Our study sheds light on the dynamics and potential impact of recombinant variants on the COVID-19 and highlights the urgent need for continued monitoring SARS-CoV-2 genomic evolution
This is a cross-sectional study conducted with the approval of the Research Ethics Committee of the Universidade Federal de Santa Maria (CAAE: 51019821.0.0000.5346)
ensuring compliance with ethical guidelines
the amount of sequenced samples that can be used in genomic surveillance is decreasing
We also conducted a search for SARS-CoV-2 sequences from RS state deposited in GISAID
focusing on samples collected during the investigation period
we selected sequences with complete genomes and excluded those with low coverage
The download of sequences was performed on May 19
Epidemiological and clinical data on the XBB-infected patients were obtained from DATASUS
and SIVEP GRIPE (data recording systems of the Brazilian Ministry of Health) in accordance with patient data protection laws
Our evaluation included data on age; sex; date of the SARS-CoV-2 positive test through RT-qPCR; first infection
reinfection or if there was no information in the databases; patient required hospitalization in the ward or ICU; patient's clinical outcome
recovered or died; death related to COVID-19 complications or other causes
we collected information on vaccination status
including vaccination strategy and schedule
SARS-CoV-2 positive samples were collected in RS state and sent to Laboratório de Biologia Molecular e Bioinformática Aplicada à Microbiologia Clínica (LABIOMIC)
The app DRAGEN COVID Lineage was used to obtain the consensus genome sequence from Illumina data
we excluded sequences that exhibited less than 75% genome coverage breadth and contained more than 3000 N (undetermined nucleotides)
consensus sequences were imported and aligned to the SARS-CoV-2 reference genome (NC_045512.2)
The "Find Variations/SNPs" tool was configured to identify variants with a minimum frequency of 0.25
Data derived from the interval between last vaccine dose and SARS-CoV-2 infection was analyzed by One-way ANOVA followed by Tukey post-hoc test
The results were considered significant when p ≤ 0.05
This study was performed in compliance with the principles of the Declaration of Helsinki
Approval was granted by the Institutional Ethical Review Board of the Universidade Federal de Santa Maria (approval number: 51019821.0.0000.5346)
The requirement for participants' consent was waived by the Institutional Ethical Review Board of the Universidade Federal de Santa Maria (approval number: 51019821.0.0000.5346)
Comprehensive overview of the COVID-19 situation in the Rio Grande do Sul state, Brazil, during epidemiological weeks 40/2022 to 17/2023, as indicated by the number of SARS-CoV-2-positive cases and deaths. The data were obtained from the official website of the Rio Grande do Sul state government, available at https://ti.saude.rs.gov.br/covid19/
SARS-CoV-2 genomic surveillance in the Rio Grande do Sul state
(A) Predominance of the XBB over other non-recombinant Omicron lineages
based on the sequenced samples analyzed in this study
Absolute (B) and relative (C) numbers of non- and XBB lineages identified in the samples
Clinical outcome and vaccination information for XBB-infected patients
(A) Clinical outcome associated with age and the number of doses and boosters of the vaccine against SARS-CoV-2
(B) Number of infections associated with age and interval between last vaccine and XBB infection
According to the health data repositories of the Brazilian Ministry of Health, 59.5% of the individuals (50 individuals) were reinfected with the XBB lineage (Fig. 3B)
A total of 28.6% (24 individuals) experienced their first SARS-CoV-2 infection with this lineage
there is an absence of recorded data on both previous infections and the XBB infection itself
suggesting a potential failure in the reporting system
43.1% of the reinfected individuals were over 60 years of age
followed by those in the 40–59 age group (41.2%)
50% of those experiencing their first infection were aged between 40 and 59 years
There was considerable variability in the interval between infection and the administration of the last vaccine dose
it is noteworthy that 58.3% of the infected individuals had received their last dose or booster more than a year prior
all had previously received at least one vaccine dose
indicating the presence of hybrid immunity against the virus
We analyzed the interval between the occurrence of XBB infection and the administration of the last vaccine dose (Fig. 4). The results revealed that among individuals aged 12–39, 40–60, and > 60 years, the median intervals were 403, 442, and 351 days, respectively. The three infected individuals in the 0–11 age group had not received any vaccine doses.
Clinical outcome and vaccination information for XBB-infected patients according to age
Data were expressed as median ± interquartile interval (n = 17–37) and analyzed by one-way ANOVA followed by Tukey post-hoc test
There were no statistical differences (p > 0.05)
Mutational profile and variant frequency of the SARS-CoV-2 recombinant variant XBB in the genome coding region (A)
The Receptor-Binding Domain (RBD) of the S gene
The frequency of each mutation is represented by the height of the corresponding bar
The spread of XBB* lineages in the Southern region of Brazil followed a similar temporal pattern to the national trend but exhibited variations in the prevalence of specific XBB* groups
the dominance of the XBB* + F486P + F456L + L455F group in the Southern region emerged later than in other Brazilian regions
the majority of individuals who experienced reinfection with the new recombinant variant had previously been vaccinated
thus possessing hybrid immunity against SARS-CoV-2
but an extended period had elapsed since vaccination or prior infection
it is not possible to determine the exact cause of reinfection events
reinfections may result from a complex interaction between immunity
This high reinfection rate highlights the need for continued monitoring of variant-specific immune evasion and the effectiveness of existing vaccines
they suggest that future vaccination strategies should consider the development of vaccines targeting specific variants and potentially enhancing booster schemes to maintain robust immunity
Understanding the underlying mechanisms of reinfection can inform public health policies and guide the design of more effective vaccination programs
we did not have access to the patients' clinical data to perform this assessment
it is imperative to prioritize genomic surveillance as a cornerstone of pandemic preparedness
the present study is subject to limitations
Due to the lack of coordinated and standardized sampling criteria from the health system and government
The sequenced samples were those that tested positive by RT-qPCR and were subsequently sent to our laboratory for sequencing
the Brazilian Ministry of Health issued a Guideline Note recommending rapid antigen tests for suspected SARS-CoV-2 cases
This change led to a substantial decrease in the number of samples available for genomic sequencing
our study is geographically limited to evaluating the state of RS
we believe our findings contribute to understanding the pandemic's trajectory in Brazil and offer valuable insights for genomic surveillance
public health strategies must encourage booster doses and prioritize these for high-risk groups such as the elderly and those with underlying health conditions
Improving the reporting system for accurate and timely recording of cases and reinfections is crucial for better public health responses
Increasing funding for genomic surveillance will ensure continuous monitoring of variants
Establishing a centralized genomic surveillance system and integrating different data systems (e.g.
SIVEP GRIPE) will streamline data collection and facilitate real-time access to epidemiological and clinical data
The findings of our study provide insights into the first time that a recombinant lineage predominated in SARS-CoV-2 positive cases in the RS state
Introduction of the XBB lineage coincided with an increase in the number of confirmed COVID-19 cases
implying a potential association between the new lineage and increased transmissibility
Clinical outcomes among XBB-infected patients further emphasized the importance of vaccination
While the vast majority of XBB-infected patients recovered
most of these patients had received their last vaccine dose or booster more than a year prior
suggesting a possible waning of vaccine-induced immunity over time
Mutation profile of the XBB lineage needs monitoring
given its potential to influence viral transmission
may impact the effectiveness of current therapeutic interventions and vaccines against SARS-CoV-2
The detection and characterization of the XBB lineage highlight the necessity for rigorous
Maintaining an updated vaccination schedule and utilizing genomic surveillance are instrumental in controlling the spread and impact of emerging SARS-CoV-2 variants
Epidemiological and clinical data were obtained from DATASUS

A delegation from the government of Uganda recently visited some of Brazil’s top tilapia farmers
as they seek to grow their own aquaculture sector
One of the key focal points was the potential economic and environmental impacts of Brazil’s increasingly industrial-scale aquaculture sector
This was done by showcasing the scale of feed manufacturing required to support a large industry
with a particular focus on ingredient supply chains and a demonstration of how environmental risk and impact are effectively managed by industry and regulators
Biosecurity, as well as fish health and welfare
were also discussed and the visit explored the prerequisites for growing the industry: including the need for knowledge and skills development
and a demonstration of the technology and innovation that could be applicable to Uganda’s aquaculture development plans
The itinerary including a visit to Raguife
which is the largest independent aquafeed producer in Brazil
who showed the full operation of the factory and discussed the ingredient supply chains required to produce 100,000 tonnes of feed per year
The group also farm and market tilapia through the brand Brazilian Fish
The delegation visited one of their farms as well
The delegation then visited Global Peixe – a major tilapia hatchery/nursery run by Emerson Esteves, a recognised pioneer in the industry. Global Peixe produce 100 million fingerlings per year and 40 million vaccinated juveniles. They have recently constructed a series of ponds and a new automated vaccination station to give them greater control to do this on land
Next up was Grupo BTJ – an increasingly important player in the industry with farming and processing facilities
We were welcomed by brothers Henrique Junqueira (farming) and Felipe Junqueira (processing)
BTJ slaughter their own fish from their three production sites
but also buy from other farms when required to meet customer demand
The delegation was met by a number of key players from Brazil’s Ministry of Fisheries and Aquaculture
fish health and welfare are part of the aquaculture development programme being implemented by the ministry
The Ugandans departed with a number of important lessons from Brazil
Among other things they saw how the development of the commercial tilapia sector has been led by companies
typically with existing experience in commercial agriculture and livestock production
and site identification carried out by the government (state and federal level) has provided a clear framework to give investors confidence
to grow a commercial aquaculture sector the following are essential: a consistent supply of quality feed
and fish that can cope with the environment and express their natural behaviour
the sector and its service industries employ 3.5 million people
Commercial tilapia aquaculture is helping drive economic development and provides high-quality
low-carbon food through maximising the use of circular economy practices
There are expectations that the visit will open opportunities for joint development initiatives
Murilo Quintiliano graduated in Animal Sciences at UNESP - Jaboticabal - Brazil in 2005 and since then has been working alongside universities
research centres and private companies to facilitate a better farming environment
In 2008 he joined FAI to help address the challenges in Brazilian food production and implement changes
Quintiliano was worked to improve conditions for Brazil's terrestrial livestock as well as tilapia
He is passionate about animal welfare and the benefits it brings to the economics
environment and ethics of livestock production
Record highs delay start of classes in Rio Grande do Sul
where floods linked to climate crisis left 180 dead last May
During historic floods last May that left more than 180 dead in Brazil’s southernmost state
the water rose to the ceiling of the Olindo Flores school in the city of São Leopoldo
When classes resumed more than a month later
its 500 students had to be relocated to another school for months
they were due to start the new school year but could not do so – this time because of an intense heatwave affecting the state
The start of the school year was pushed back after a court ruling on behalf of a teachers’ union
which had argued that classrooms lacked adequate ventilation and water supplies for students
the highest temperatures recorded in Brazilian cities have all been in Rio Grande do Sul
a state which is normally milder than other Brazilian regions closer to the equator
Marina Hirota, a scientist and professor of meteorology at the Federal University of Santa Catarina, said that while it was still too early for in-depth analyses of the current heatwave, both it and last year’s floods are “potentially linked to the climate crisis”.
Read more“These extreme events – heatwaves, cold spells and intense flooding like what happened in Rio Grande do Sul in 2024
followed now by an extreme drought – are becoming more frequent and more intense … and this frequency and intensity are the result of the climate crisis,” she said
Olindo Flores school in São Leopoldo was one of the few that had air conditioning
but the equipment was lost in last year’s floods and has not yet been replaced during reconstruction
and there were some hot days – but nothing like this – and it was already difficult for teachers and students,” said Luiz Henrique Becker
On Sunday, after the union’s request, a judge suspended the start of classes for at least a week. The government appealed, and yesterday, an appellate judge ruled that classes could resume on Thursday
“We will keep fighting for the government to install air conditioning in all schools because new heatwaves will happen,” said Rosane Zan
who is also a researcher with a tropical ecology group at the Serrapilheira Institute
we get this extreme heat immediately after … We’re becoming less and less able to predict these events because they never used to happen this way … For the living beings in these places – whether humans
animals or plants – it’s also becoming ever more difficult to adapt to such abrupt changes.”
which account for more than half of the world’s soybean supply
are expecting smaller harvests this crop season
Major agricultural agencies and consultancies have already slashed their forecasts for the soybean output in 2021-22 as a result of severe drought since November
Department of Agriculture has also reduced its estimate of global soybean production
And soybean futures on the Chicago Mercantile Exchange have reached a nine-year highs levels in February on concerns about the more unfavorable crop weather in South America and the recent Russia’s invasion of Ukraine
This article focuses on the countries for which production declines have been confirmed by state statistical agencies so far
the National Supply Company (Conab) pegged Brazil’s soybean crop at 4,610 million bushels
down from the January projection of 5,162 million bushels
Compared with the last harvest (5,076 million bushels)
the current projection would be a reduction of 9.2%
the crop still would be the second largest in history
the world’s largest producer and exporter
are concentrated mainly in the southern states
Paraná (PR) and Mato Grosso do Sul (MS) – where the La Nina phenomenon caused drought during the summer
the world’s top soybean oil and meal exporter
with almost the entire country suffering from a drought since November
indicates that Argentina will harvest 1,470 million bushels this season
That represents a 7.2% reduction from last year’s crop
According to Rosario grains exchange (BCR)
with soil conditions ranging from scarcity to drought in the provinces of Santa Fe
the world’s fourth-largest soybean exporter
Paraguay’s soybean harvest could fall by as much as 50%
to some 165 million bushels in what would be the lowest level in the last decade
the nation produced 378 million bushels of soybeans
The last time Paraguay produced less than 160 million bushels of soybeans was in the 2011-12 cycle
Paraguay exports over half of the soybeans it produces
and its economy depends heavily on shipments abroad of raw materials
according to data from the Paraguayan Chamber of Soybean Exporters
Frustration and records within BrazilLa Nina events favor increased rain across northern Brazil and decreased rain in southern Brazil
Such has been the case this year as southern Brazil has gone deep into drought
In the southern states of Rio Grande do Sul (RS)
precipitation has been very scarce since November 2021
the soybean yields for these three states are projected to be 35% lower than last season
with almost 30% of the area harvested by the third week of February
production is expected to reach only 479 million bushels
a decrease of 34.4% in comparison to last year
production is predicted to be 505 million bushels
Drought severely affected Rio Grande do Sul
High temperatures and drought could result in an incomplete planting season
If the troublesome weather brought about by the La Niña phenomenon continues to worsen in February
it is possible that there could be more damage to crops
and soybean production could be lower than the current projection
Paraná and Rio Grande do Sul are historically the second and third largest soybean producers in Brazil
The soybean crop in Mato Grosso do Sul (MS) is expected to be 20% smaller than last season
is expected to have a record-breaking 2021-22 harvest
The most recent forecast from Conab projects farmers will produce 1,432 million bushels
an increase of 6.7% in relation to last year
Mato Grosso had harvested 70% of the area planted
also is expected to have a record soybean harvest
The production this season is projected to reach a record of 552 million bushels
an area in the Brazilian North and Northeast formed by the states of the Maranhão (MA)
is also projected to reach historical production levels this season
The higher production levels are attributed to favorable weather as well as an increase in the planted area and the use of technologies such as seeds adapted specifically for this region
Considered one of the main agricultural frontiers in Brazil
the region has numerous favorable qualities for modern agriculture
With all indications pointing toward a tightening of global supply in the first half of 2022
in addition to the impacts from the Russian military attack on Ukraine
soybeans futures traded in Chicago in February have been the most expensive since 2012
soybean prices continue to hit new records in the Brazilian market
Prices in the port of Paranaguá (PR) closed on February 24 at BRL 201,35 ($39.35) per 2.2 bushels
according to data from the Center for Advanced Studies in Applied Economics of Luiz de Queiroz College of Agriculture at the University of São Paulo (Cepea/Esalq/USP)
This is the highest value in Cepea’s history
The average monthly cash price in the port of Paranaguá for soybeans increased 17,3% from November 2021 to February 2022
Depending on the weather and international market
soybean prices in Brazil could continue to rise
The changing soybean market dynamics in South America may have bullish implications on exports of the upcoming U.S
soybean crop and may lead to higher US soybean production in 2022
In response to climbing soybean prices in South America
soybean export prices are up 25 percent since December (USDA
The Miami Science Fiction Film Festival was held January 18-19
Mike Cassutt and I were there… we had a series of meetings that week
and we’d enetered MARY-MARGARET ROAD-GRADER in the festival
as I reported downstream in my post about the festival
Steven Paul Judd took two of them; he took Best Director
and also won the prestigious Russell Bates Award
MARY-MARGARET also won honors for its costuming and wardrobe… and Miami was kind enough to present me with a lifetime achievement award
We were not able to attend the awards presentation at the festival
and I believe there were some delays with the trophies
and the rockets arrived here in Santa Fe a couple of day ago
The Bates Award was shipped directly to Steven Paul Judd; the other three turned up here
(Steven’s when he returns to Santa Fe in a few weeks to direct his next episode of DARK WINDS
He has been doing an amazing job for us since he joined the show
And DARK WINDS itself has been kicking ass and taking names
you don’t know what you are missing)
And speaking of film festivals… if any of you are in Texas this weekend
do check out the schedule for the Dallas International Film Festival
I am told it’s scheduled for Sunday
Sid Khalsa will be on hand to help present it
TUC was adapted by Michael Cassutt from Howard’s Nebula-winning short story
in a poem called “The Law of the Jungle.”
Ned Stark echoed those words in A GAME OF THRONES
“When the snows fall and the white winds blow
their prey included the megafauna of the period: giant ground sloths
a lone wolf would have had a helluva time bringing down any of these by itself
There is evidence that direwolf packs were much
much larger than those of their modern descendants
Colossal Biosciences has given us a pack too
I don’t believe that Khaleesi is howling yet
When I visited Colossal back in February
I had the honor of meetings Romulus and Remus and holding them in my arms
though I hope to make her acquaintance later
Colossal announced the return of the direwolves last week
Since then the story has spread all over the world
Millions of people seem to be as thrilled by the news as I am
the debates are raging all over the internet
I will let the scientists argue the genetics
The things that trouble me more are the people saying
those arguing that god made the direwolf extinct and man has no right to undo what he has done
the movie buffs who think we’re now blundering into Jurassic Park (fine book
we are not going to have packs of direwolves chasing children through Central Park)… but most of all
I am horrified by those now saying that now that we have mastered de-extinction
we don’t need the Endangered Species Act
so let’s gut that for the benefit of the oil and gas industry
(Trump and his MAGies have been trying to do this for years)
we have people saying we should not be bring back extinct animals
that we should be spending our money defending living animals whose numbers are dwindling as their habitats vanish
Colossal is not trying to bring back extinct animals in lieu of defending endangered ones
Romulus and Remus and their sister are not the only miracles Ben Lamm
Beth Shapiro and their incredible team have wrought; they have also been cloning red wolves
the most severely threatened of today’s wolves
It is a matter of learning; the techniques that Colossal is pioneering will benefit both
and a hundred other animals may follow… in time… maybe ten years
Any of them who make it back will make the world a better place
But we need to protect the animals we have now too
The woolly mammoth should not replace the elephant; Earth is big enough for both
yes… but we deserve dodos and moas and smilodons as well
there are no stronger supporters of the Endangered Species Act than Ben Lamm and the good folk at Colossal
the film adaptation of my short story by the same name
had its premiere at my Jean Cocteau Cinema in Santa Fe on February 8
The story was one of my earliest fantasies
originally published in 1972 in an anthology called AMAZONS II
There was a time when I hoped to make Gray Alys a series character
but… alas… I never got around to writing that all important second story
We’ve been making steady progress with the series of short films that I’ve been producing the last couple of years
most of them based on classic short stories by Howard Waldrop
MARY-MARGARET ROAD GRADER and THE UGLY CHICKENS are both out of the festival circuit
you can catch THE UGLY CHICKENS at the Dallas International Film Festival
and should be ready for the festival circuit in another month or two
we have just wrapped our first Non Waldrop short
We are just about to start submitting it to film fests around the country and the world; will be sure to let you know when and where it gets accepted
I promised an exciting announcement in that last blog post of mine
the one I wrote last night that went up this morning on my Not A Blog
it was not going to be the delivery of THE WINDS OF WINTER
But it was going to be something very cool
had it all lined up so the story would break on April 8
in dozens of different magazines and magazines all around the world
Only it turned out that one of the news outlets jumped the gun
and broke the story this morning while everyone else was sleeping
so the rest of the world had no choice but to scramble along afterwards
I’ve been holding my tongue for months now
sworn to silence yet dying to tell the world
and the rest of their team of mad scientists at Colossal
the world leader in the science of “de-extinction.”
I do not have the expertise to tell you how they done it
who understand the details way better than a fantasist like me
Landmark achievement is a scientific breakthrough for global conservation efforts and also allowed for the successful birth of four critically endangered red wolves through novel non-invasive cloning technology
Picture of Colossal’s Dire Wolves; Romulus and Remus at age three months
DALLAS–(BUSINESS WIRE)–Colossal Biosciences
today announces the rebirth of the once extinct dire wolf
the world’s first successfully de-extincted animal
largely assumed to be a legendary creature made famous from the HBO hit series Game of Thrones
was an American canid that had previously been extinct for over 12,500 years
The successful birth of three dire wolves is a revolutionary milestone of scientific progress that illustrates another leap forward in Colossal’s de-extinction technologies and is a critical step on the pathway to the de-extinction of other target species
which previously held the record for unique germline edits in an animal with 8 precision edits
Colossal has made 20 unique precision germline edits including 15 edits from the ancient gene variants that have not existed in over 12,000 years
setting a new bar for precision germline editing in any animal
This massive milestone is the first of many coming examples demonstrating that our end-to-end de-extinction technology stack works,” said CEO of Colossal Ben Lamm
“Our team took DNA from a 13,000 year old tooth and a 72,000 year old skull and made healthy dire wolf puppies
‘any sufficiently advanced technology is indistinguishable from magic.’ Today
our team gets to unveil some of the magic they are working on and its broader impact on conservation.”
The three litters of Colossal’s dire wolves include two adolescent males (Romulus and Remus) and one female puppy (Khaleesi)
Colossal also birthed two litters of red wolves from three different genetic founder lines
These litters include one adolescent female red wolf (Hope) and three male red wolf puppies (Blaze
and testing genetic diversity should be done well before important endangered animal species like the red wolf are lost
Another source of ecosystem variety stems from our new technologies to de-extinct lost genes
including the largest number of precise genomic edits in a healthy vertebrate so far
A capability that is growing exponentially,” said Harvard geneticist and co-founder of Colossal
The wolves are thriving on a 2,000+ acre secure expansive ecological preserve that is certified by the American Humane Society and registered with USDA
Colossal employs ten full time animal care staff to support the wolves’ physical and mental well-being
which includes specialized engagement zones and habit types
zoo-grade fencing with redundant perimeter security
the wolves are continuously monitored through on-site live cameras
and drone tracking to ensure their safety and welfare
six acre secure site where the dire wolves can be further tended to and studied
This smaller area also supports an on-site veterinary clinic
“Colossal has achieved American Humane Society Certification
the prestigious designation ensuring excellence in animal welfare and care
Optimal welfare is evidenced by spacious habitats with ample space and opportunity for animals to socialize
highly engaged and devoted to the animals in their care
We congratulate Colossal as a shining example of excellence in humane care and welfare
The technology they are pursuing may be the key to reversing the sixth mass extinction and making extinction events a thing of the past.” – Robin Ganzert
The conservation property will provide lifetime care
The wolves will be monitored and observed to assess their readiness to move into larger protected and managed care facilities
Colossal plans to restore the species in secure and expansive ecological preserves potentially on indigenous land
“The de-extinction of the dire wolf is more than a biological revival
Its birth symbolizes a reawakening – a return of an ancient spirit to the world
The dire wolf carries the echoes of our ancestors
and their connection to the wild,” shared MHA Nation Tribal Chairman Mark Fox
“Its presence would remind us of our responsibility as stewards of the Earth – to protect not just the wolf
The work of the team at Colossal Biosciences is not only significant to our lands and people
but for conservation efforts across the globe
The ability for technological innovation to bring forth something so culturally and spiritually significant to indigenous people is paralleled by the far reaching impacts that this technology provides for the future of stewardship on our planet in species diversity and conservation.”
Dire wolves (Aenocyon dirus) were distributed across the American midcontinent during the Pleistocene ice ages
that the lineage first appeared during the Late Pliocene
as a consequence of admixture between two more ancient (and now extinct) canid lineages
Dire wolves were as much as 25% larger than gray wolves and had a slightly wider head
their diet comprised at least 70% meat from mostly horses and bison
Dire wolves went extinct at the end of the most recent ice age
“I have spent nearly 10,000 days in the field studying the behavior of the wolves in Yellowstone National Park
I worked in Denali National Park in Alaska where I studied wildlife species that live on the tundra: wolves
I spent some time on the northern and western coasts of Alaska
I was born far too late to see now extinct Ice Age species such as dire wolves and mammoths
my Celtic ancestors probably lived among those animals in northern Europe and may have had some role in contributing to their extinction
I never thought I might live in a time when we have the science to bring back those species and restore them to selected sections of their former homeland
I have a dream that some time in the near future I can go back to Alaska
or a similar place in Northern Europe or Asia
and see those extinct species that have been brought back thanks to science
I will begin to study the behavior of dire wolves.” – Rick Mcintyre
author and internationally recognized as one of the world’s foremost experts on wild wolf behavior
and Colossal Conservation Advisory Board Member
introduction to the dire wolf occurred through the lens of entertainment
Mentions of this legendary prehistoric canid in role-playing games like Dungeons & Dragons; video games like World of Warcraft; music like the Grateful Dead’s aptly-named song
Martin’s best-selling fantasy novel series
A Song of Ice and Fire and its TV adaptation
“Many people view dire wolves as mythical creatures that only exist in a fantasy world
they have a rich history of contributing to the American ecosystem,” said Game of Thrones creator
and Colossal Investor and Cultural Advisor George R.R
but Ben and Colossal have created magic by bringing these majestic beasts back to our world.”
The Science Behind the Return of the Dire Wolf
The birth of dire wolf pups proves the efficacy of Colossal’s de-extinction protocols and the feasibility of creating a standardized toolkit for de-extinction
The dire wolf pups set the record for number of precise genetic edits in any living species
The company performed a record 20 precise edits to the genome
all modifications derived from analysis of the dire wolf genome with 15 of those edits being the exact extinct variants
Together these edits contribute to a larger
Colossal extracted ancient DNA from two dire wolf fossils: a tooth from Sheridan Pit
The team deeply sequenced the extracted DNA and used Colossal’s novel approach to iteratively assemble high quality ancient genomes
resulting in a 3.4-fold coverage genome from the tooth and 12.8-fold coverage genome from the inner ear bone
this data provided more than 500x more coverage of the dire wolf genome than was available previously
Colossal’s computational analysis of the reconstructed dire wolf genome revealed several unknowns of dire wolf evolution
Previous work could not resolve the origin of dire wolves
leading to speculation that jackals may be their closest living relative
Analyses of the high quality dire wolf genome
revealed that the gray wolf is the closest living relative of dire wolves – with dire wolves and gray wolves sharing 99.5% of their DNA code
the analysis also revealed that dire wolves have a hybrid ancestry
which helps to explain the previous uncertainty
Colossal’s analyses indicated that the dire wolf lineage emerged between 3.5 and 2.5 million years ago as a consequence of hybridization between two ancient canid lineages: an ancient and early member of the tribe Canini
which may be represented in the fossil record as Eucyon or Xenocyon
and a lineage that was part of the early diversification of wolf-like lineages including wolves
“Our novel approach to iteratively improve our ancient genome in the absence of a perfect reference sets a new standard for paleogenome reconstruction,” said Dr
Colossal’s Chief Science Officer and a leading expert in the field of ancient DNA
”Together with improved approaches to recover ancient DNA
these computational advances allowed us to resolve the evolutionary history of dire wolves and establish the genomic foundation for de-extinction – specifically for selecting with confidence dire wolf specific genetic variants that establish our targets for gene editing.”
Analyses of the dire wolf genome allowed Colossal to identify the key variants in dire wolves that are not found in other canids that tell the story of dire wolf evolution
Colossal identified multiple genes undergoing positive selection that are linked to dire wolf skeletal
The team discovered dire wolf specific variants in essential pigmentation genes revealing that dire wolves had a white coat color – a fact that is impossible to glean from fossil remains alone
The team also identified dire wolf specific variants in regulatory regions that alter the expression of genes
Colossal used its proprietary computational pipeline and software to select 20 gene edits across 14 distinct loci as targets for dire wolf de-extinction
focusing on the core traits that made dire wolves unique including size
the team used gray wolves – the closest living relative of dire wolves – as the donor species for establishing cell lines
Using Colossal’s novel approach to establish cell lines from a standard blood draw
the team collected blood during a normal veterinary procedure and established cell lines from blood epithelial progenitor cells (EPCs)
The team then performed multiplex genome editing of these cells followed by whole genome sequencing to confirm editing efficiency and identify any alterations to the genome arising during extended cell culture
The Colossal dire wolf team selected high quality cells with normal karyotypes for cloning by somatic cell nuclear transfer into donor oocytes
followed by short-term culture to confirm cleavage
Healthy developing embryos were then transferred into surrogates for interspecies gestation
Three pregnancies led to births of the first de-extinct species
“The de-extinction of the dire wolf and an end-to-end system for de-extinction is transformative and heralds an entirely new era of human stewardship of life,” said Dr
a scientific advisor and member of the board of observers for Colossal
“The same technologies that created the dire wolf can directly help save a variety of other endangered animals as well
This is an extraordinary technological leap in genetic engineering efforts for both science and for conservation as well as preservation of life
and a wonderful example of the power of biotechnology to protect species
Colossal edited 15 extinct dire wolf variants into the donor gray wolf genome
creating dire wolves that express genes that have not been expressed for more than 10,000 years
These target genes were selected because each is linked to one or more key traits that made dire wolves unique among canids
a serine protease that is expressed in hair follicles and suppresses the agouti pathway
The dire wolf CORIN variants impact pigmentation in a way that leads to a light coat color
Colossal also edited dire wolf specific variants in a multi-gene regulatory module that has been linked to variation in body size as well as ear
The region encodes eight genes that establish species-specific constraints in skeletal size and structure
and has been linked to features including differences in human height and the diverse beak shapes among finch species
One gene encoded by this module – HMGA2 – is directly associated with body size in dogs and wolves
Another gene in this module – MSRB3 – has been linked to variation in ear and skull shape among canines and other mammals
Given the role of these genes in establishing species-specific size and morphology
the dire wolf team edited dire wolf-specific variants into gene enhancers (DNA sequences make it more likely that the gene will be transcribed into RNA) in this genomic region
For each high impact variant identified as linked to a target phenotype
Colossal’s dire wolf team created a detailed profile of all potential impacts on a donor gray wolf genome
the team discarded variants that would incur some risk outside of the predicted phenotype or prioritized variants already evolved in gray wolves with the predicted phenotype
Colossal edited the protein coding region of LCORL
a transcription factor that regulates gene expression by influencing whether a gene is transcribed
Variations in LCORL have been linked to variation in body size in many species
The dire wolf has three changes to the LCORL protein sequence that are predicted via 3D modeling to alter the way the protein folds precisely at the location where LCORL should bind to a major gene silencing complex known as the PRC2 domain
large dog breeds (which are domesticated gray wolves) have a variant of LCORL that is missing the PRC2 domain entirely
As the dire wolf version is predicted to have a similar phenotypic impact as the variant found in larger dog breeds
and because of the potential for LCORL to interact with other genes in the gray wolf genetic background that are not edited
Colossal’s dire wolves express the protein that is found in the largest grey wolves
This choice allows for the predicted phenotypic impact and without any additional risk
“Functional de-extinction uses the safest and most effective approach to bring back the lost phenotypes that make an extinct species unique,” said Shapiro
“We turn to ancient DNA to learn as much as we can about each species and
to link specific extinct DNA sequence variants to each key trait
we learn that variants already present in the surrogate species can be used to engineer that key trait
engineering existing variants into the donor genome is an optimal path
as that path provides strong confidence in the outcome with minimal risk to the animal.”
The dire wolf genome has protein-coding substitutions in three essential pigmentation genes: OCA2
which directly impact the function and development of melanocytes
While these variants would have led to a light coat in dire wolves
variation in these genes in gray wolves can lead to deafness and blindness
The team therefore engineered a light colored coat in Colossal’s dire wolves via a path known to be safe in gray wolves: by inducing loss-of-function to MC1R and MFSD12
These genes influence expression of pigments eumelanin (black) and pheomelanin (red) in melanocytes that deposit to the coat
achieving the lighter pigmented coat color phenotype suggested by the dire wolf genome but without any potential health impacts
“When I learned of Colossal’s approach to engineering the light coat color into their dire wolves
I was simultaneously impressed and relieved,” said Elinor Karlsson
Associate Professor in Bioinformatics and Integrative Biology at the UMass Chan Medical School and Director of Vertebrate Genomics at the Broad Institute of MIT and Harvard
“By choosing to engineer in variants that have already passed evolution’s clinical trial
Colossal is demonstrating their dedication to an ethical approach to de-extinction.”
The path to the dire wolf and the red wolf also led to innovations reaching beyond de-extinction
including advances in ancient DNA genome reconstruction and genotype-to-phenotype prediction
as well as optimized tools for multiplex gene editing
Another important contribution from the project are Colossal protocols to establish cell lines directly from blood that can be used for somatic cell nuclear transfer
The collection of whole blood is a rapid and noninvasive procedure that is routinely carried out on sedated wolves for veterinary monitoring purposes
These field collections provide a valuable opportunity to isolate expandable endothelial progenitor cells (EPCs)
which are cells that are involved in vascular repair and neovascularization and differentiate into the cells that line blood vessels
Isolated EPC cell lines can be frozen for later genomic analyses and
can be used to successfully clone wild canids
Biobanking and cloning EPCs from threatened or endangered populations of wild wolves provides a safety net to preserve the genomic diversity present today from further loss and extinction
“Whether due to natural or human-induced changes in climate
the extinction of an untold number of species is a loss to our planet’s history and biodiversity
Modern genetics lets us peer into the past
and modern genetic engineering lets us recover what was lost and might yet thrive
it invents the tools that let us protect what is still here
As humans we have a unique capacity and moral obligation to steward the earth for the benefit of ourselves and all living things
for now and for the future.” – Alta Charo
Professor of Law and Bioethics and Colossal Bioethics Lead
The technology developed within the Colossal de-extinction pipeline has immediate applications for conservation efforts globally
The research undertaken to birth the dire wolf has been successfully paralleled to the birth of two litters of the red wolf
Colossal’s two litters of red wolves include one female and three males from a total of three different cell lines
collected from the southwest Louisiana population
using its novel method of insolating EPCs following a standard blood draw
The pups were born after somatic cell nuclear transfer into a donor oocyte followed by embryogenesis and embryo transfer into a surrogate mother
Both embryo transfers resulted in the birth of healthy red wolf pups
“In a world where humans are rapidly eroding the environment
One of the most impactful ways to be an ally is to use science to help discover and preserve lost genes
We now have the technology that can edit DNA to increase resilience in species that are facing extinction or to revive extinct genetic diversity and species
We get to witness the de-extinction of the dire wolf
and just the start of numerous species we can bring back to create a better
I am beyond thrilled that such technologies are also being leveraged to support programs of preventing extinction in endangered species like the red wolf.” – Bridgett vonHoldt
Princeton Associate Professor of Evolutionary Genomics and Epigenetics
fewer than 20 red wolves remain in North America
which makes them the most endangered wolves on the planet
Thousands of red wolves once roamed across most of eastern North America
The Endangered Species Act and a captive breeding program have been critical to securing the reintroduction of red wolves back into the wild in eastern North Carolina
The Fish and Wildlife Service’s Red Wolf Recovery Program successfully grew the wild population to more than 120 wolves
the population crashed to as few as seven wolves
but red wolves have struggled to regain their numbers
One challenge has been to maintain genetic diversity among the captive and re-wilded population of red wolves
all of which descend from only 12 founder individuals
Adding Colossal’s red wolves to the captive breeding population would increase the number of founding lineages by 25%
“The dire wolf project is surreal and unreal at the same time
It’s recreating reality that stemmed from reality
To think that in this day dire wolves aren’t just mythical illusions and tales told in movies that we believe may have had origins in reality…Now
we have the science and ingenuity to bring life back to once existing reality
Colossal is drastically changing the prognosis for countless endangered species around the world,” said Aurelia Skipwith
former Director of the US Fish and Wildlife
“The company’s work to combat extinction of the red wolf creates hope for so many other critically endangered species fighting for survival.”
The research program for the dire wolf has also helped efforts to develop technologies for the red ‘ghost’ wolf
found only on the gulf coast of Texas and Louisiana who carry lost DNA and biodiversity of the red wolf
Bridgett vonHoldt of Princeton University and Dr
Kristin Brzesk of Michigan Technological University lead the Gulf Coast Canine Project which aims to understand the genetic ancestry of the wild canines persisting along the Gulf Coast of the United States
They study how red wolf ancestry shapes morphology and behavior
and the support of Colossal has helped them accelerate their research through the inclusion of data from the red wolf genome
the assembly of a reference genome for the recovery population’s red wolves
and finally the creation of a pangenome for US native canids
The hope is that this work can set precedent for other species with a complicated genetic history
while also improving the capacity of conservation efforts for the red wolf
In addition to the challenges of reintroduction
the red wolf’s biggest threat of extinction comes from limited genetic diversity that resulted from the population’s bottleneck that occurred during its rapid decline
The technology and understanding developed through Colossal’s red ‘ghost’ wolf project has now unlocked additional genetic diversity and red wolf ancestry that can be a resource to create a genetic rescue program for the red wolf population
I applaud Colossal for taking bold and innovative steps to arrest and reverse the crisis by developing cutting edge genetic techniques to undergird reintroduction efforts of imperiled species
Colossal creates potential to increase the genetic diversity of this species which exists only because of a captive population founded by a paltry 14 individuals
Perfecting genomic tools to integrate ‘ghost alleles’ from Gulf Coast canids would increase red wolf genetic diversity and generate knowledge for recovering other imperiled species
that are compromised by restricted ranges and reduced genetic diversity.”- Mike Phillips
Director of the Turner Endangered Species Fund and project lead for rewilding gray wolves in the Greater Yellowstone Ecosystem
Colossal’s long term goal is for their red wolves to be re-wilded through current US conservation efforts in collaboration with the US government
“Colossal’s successful de-extinction of the dire wolf represents a massive coup for conservation,” said Matt James
Colossal’s Chief Animal Officer and Colossal Foundation Executive Director
“The technologies developed on the path to the dire wolf are already opening up new opportunities to rescue critically endangered canids
The creation of less-invasive sampling tools such as our EPC blood cloning platform allows for the conservation community to ramp up biobanking efforts of those species on the brink.”
Colossal’s de-extinction mission always includes plans to rewild associated species in alignment with global conservation efforts
Research suggests that rewilding wolves can have massive impacts on factors that drive climate change and support biodiversity
Inspired by the US Fish and Wildlife’s bold efforts to rescue the red wolf from the brink of extinction
Colossal has created technological platforms to offer key tools to those in the fight to save the world’s most endangered wolf
“Today’s dire wolf announcement represents an exciting scientific step and demonstrates the power and possibilities of genetic technologies,” said Barney Long
Senior Director of Conservation Strategy for Re:Wild
“These technologies will likely transform the conservation of critically endangered species that still exist
and we are excited to apply them to prevent extinctions
inbred populations to inserting disease resistance into imperiled species
the genetic technologies being developed by Colossal have immense potential to greatly speed up the recovery of species on the brink of extinction.”
Colossal will provide more information about the rescue of the red wolf and restoration of the dire wolf in the coming months following extensive feasibility studies
and tracking of the health and well-being of the new species
“As someone who’s fascinated with canids—I’ve written about coyotes and wolves—the idea of being able to have dire wolves again is tremendously
and I think it’s going to be exciting to a lot of people
I would say that we’re very likely to have animals once again that we thought were always gone—just as I once thought I was never going to get to hear a wolf howl… That was something I really never thought I’d have a chance to experience
we’re going to get to experience what Henry David Thoreau lamented back in the 1850s—that he wasn’t getting to experience an entire heaven and an entire Earth
And I think that’s something to look forward to.” – Dan Flores
Hammond Professor Emeritus of the History of the American West at the University of Montana-Missoula
and innovative gray wolf conservation programs are all made possible through Colossal’s collaborative work with a broad spectrum of Indigenous communities

There’s so much more to say… and a lot of stories out there are saying it
who phoned me up from New Zealand with a mysterious suggestion that I phone this guy named Ben Lamm
who had something huge he wanted to share with me
but I could hear the excitement in his voice
But I visited the La Brea Tar Pits in LA a few decades back
Most of my readers will have heard the story of how I writing a science fiction novel in the summer of 1991 when a scene came to me
the first chapter of GAME OF THRONES where they find the direwolf pups in the summer snows
But it grabbed hold of me so hard that I put the other novel aside and began to write A SONG OF ICE & FIRE
I have to say the rebirth of the direwolf has stirred me as no scientific news has since Neil Armstrong waled on the moon
I’m glad that I was finally able to blog about worldcon and the Alfies
We got back from Europe in the middle of August
and it was my original hope to have that one up by the end of the month
We had a full house at the Jean Cocteau for the premiere
I’ve heard that it will hit streaming on April 8
but I don’t know if that date is locked in yet
Something else is going to be happening on April 8 as well
I am not announcing the completion of THE WINDS OF WINTER
the sixth volume of A SONG OF ICE & FIRE
Please don’t start any rumors to that effect
I am so tired of having to issue denials every time some offhand comment of mine
somehow convinces half the internet that the book is imminent
(Maybe I need to stop making offhand comments)
based on Tony Hillerman’s classic tales of Navajo detectives Joe Leaphorn and Jim Chee
to strong ratings and even stronger reviews
One critic said its past time to give Zahn McClarnon an Emmy
DW has eight episode this season (up from six for seasons 1 and 2)
We’ll have eight episodes in season four as well… and filming has already started filming
New Mexico’s amazing landscapes… lots of reasons to watch this one
As for those two guys playing chess in the jail cell in episode one… yes
but t’other hombre… some guy from the Twilight Zone
DARK WINDS is shooting just north of Santa Fe
season three of HOUSE OF THE DRAGON has also started filming
You’ll be getting eight episodes of that one too
A KNIGHT OF THE SEVEN KINGDOMS will come first
the HBO adaptation of the first Dunk & Egg novella
“The Hedge Knight.” I just watched it again last week
Ira Parker and his team are huddled together beating out “The Sworn Sword,” the second Dunk and Egg adventure
It is such a joy to see the characters come alive
Watching them makes me want to start writing the next novella tomorrow… but of course
I caught up on that when I was in London last month
or a date… but they are making progress
I am hoping we’ll know a lot more by year’s end
I also visited the Dickens house when I was in London
so I bought four more of them when I was there
And before I forget: the Milk of the Poppy is now open
just behind Beastly Books and around the corner from the Jean Cocteau Cinema

you won’t find me tending bar in Milk of the Poppy
but you may catch me having a drink from time to time
We spent a month across the pond last summer
where A KNIGHT OF THE SEVEN KINGDOMS was being filmed
and then London to call on Jane Johnson and the good folks at Voyager
The Oxford Writers House had invited me to deliver a talk on fantasy with Philip Pullman
Unfortunately Pullman was ill and had to bow out
so the event turned into a booksigning and Q&A
I really must get back there one of these days
Perhaps by then the Eagle and Child will have opened again
The last scheduled stop on our European travels was Glasgow
I was not on any programming… but in the end I hardly missed it
I attended my first worldcon in 1971 (that was Boston) and sat on my first panel in 1976 (Big Mac
in Kansas City) — those were the days of single track programming
and you had to pay your dues before they let you onto the podium with the big boys and girls
I have lost track of how many panels I’ve done since
and sometimes they were tedious; I suppose they were good promotion for my books
I spent most of the con in the hotel bar
drinking and talking with fellow writers and fans
and raising a pint to all those we have lost
Phyllis Eisenstein and Gene Wolfe and Charlie Brown
Jay Haldeman and Greg Bear and Poul Anderson and so many more
We wandered the art show and the huckster’s room
and enjoyed some great meals in Glasgow’s restaurants… the most memorable being our visit to Mr
Singh’s with the Brotherhood Without Banners
but it’s so much better in England and Scotland than over here in the US… and nowhere is better than at Mr
(I have eaten there every time I’ve been to Glasgow
and it just keeps getting better and better and better)
Regular readers of this blog will know that for the past couple of years I have been producing a series of short films based on the works of Howard Waldrop
and one of the greatest (and most original) short story writers in the history of the field
We had five films in various stages of production (and a sixth
and were able to wrap three of them before worldcon: NIGHT OF THE COOTERS (d
Mark Raso.) We’ve had them out on the festival circuit
That’s more complicated than it sounds
and I was never able to get anyone to return my phone calls to see what could be worked out
the hotel where we were staying had a small screening room in the basement
so at least I was able to invite a couple dozen friends over for a semi-private show
I am pleased to say the shorts seemed to be well received
We got a very nice review from the website WINTER IF COMING
for those of you who would like to know more about them:

We were able to screen the final cut of MARY MARGARET for him just six days before he died in January 2014
THE UGLY CHICKENS and MARY MARGARET ROAD-GRADER are still out playing festivals
The Chickens won the award for Best Short last week in San Jose at Cinequest
and will be showing again this weekend in Cleveland
Catch it if you can; it is one of Howard’s classics
The other highlight of my worldcon was the Alfie Awards banquet we held at our hotel
The Alfies are named in honor of Alfred Bester
“Fondly Fahrenheit,” THE STARS MY DESTINATION
Bester was the winner of the first Hugo Award for Best Novel (for THE DEMOLISHED MAN
He turned up at the very first Hugo Losers Party as well
and insisted he still counted as a loser since that first Hugo trophy was a made from an Oldsmobile hood ornament
and had rusted and corroded over the years
when a number of writers and fans who would surely have been nominated for a Hugo Award were squeezed out when the Puppies (Sad and Rabid) stuffed the ballot with their own favorites
There was no way to rectify that (though various people tried
with everything from wooden asterisks to rules reform to voting No Award)
My own approach was the Alfies; trophies made of old hood ornaments
given to writers and fans who missed out on nominations they likely would have gotten in a normal year
I’ve lost a fair number of them myself)
You can learn way more than you ever wanted to know about the Hugo brouhaha of 2015 in from the myriad accounts on the web
so I tweaked the Alfies as well… but the winners still seemed to appreciate them
(And that’s what awards are all about
the need for the Alfies seemed to have passed
We threw a great Hugo Losers Party that year
to John Picacio for his Mexicanx Initiative
a commendable effort to put more world in worldcon
Alfies were presented there to two titans of British publishing
Malcolm Edwards of Gollancx and Jane Johnson of Voyager
two of the leading editors in the history of our genre
neither of whom had gotten so much as a Hugo nomination in years past
There were no Alfies given at the worldcons in 2020
and I was not able to attend the 2021 con in Washington
China… and that’s where the problems came in
The Chinese fans designed a handsome Hugo trophy
for certain… but when the nomination totals were finally revealed
it became clear that the vote counting had gone seriously awry
and four possible contenders (a television show
and a major novel) were unaccountably missing from the final ballot
despite having received more than enough nominations
They had been disqualified and removed from the ballot
I won’t attempt to describe what followed
I still had a garage full of old hood ornaments
And our hotel had a room that was just the right size for a small-ish celebration to honor those who were wrongfully denied their chance to contend for a Hugo rocket
The Chengdu Hugo for Best Dramatic Presentation
was won by EVERYTHING EVERYWHERE ALL AT ONCE
Short Form went to “Babylon’s Ashes”
SANDMAN received 139 nominations in Short Form for “The Sound of Her Wings,” almost a hundred more than the EXPANSE episode
but was removed from the ballot for reasons never satisfactorily explained
the first season of SANDMAN got 50 nominations
which would not have been enough to make the ballot… but the series was removed from that category as well (just to be sure?)
He had received 90 votes during the nomination round
only one more than another perennial contender
and more than enough to make the final ballot
It was said that he was disqualified for the crime of visiting Tibet at one point
Whoever removed him did not seem to know the difference between Tibet and Nepal
but the concom had him working during our banquet
and in 1973 I was a finalist for a brand new award for Best New Writer
it is awarded to the best new writer to break in during the previous two years
XIRAN JAY ZHAO was a finalist for the Astounding Award in 2022
and I certainly felt that way in ’73
Jay got enough votes to make the ballot again in 2023
their second year of eligibility… 178
But their name did not appear on the final ballot
since BABEL would have had an excellent chance of coming out on top if the book had been nominated
The novel had already won the Nebula Award and the Locus Award
among other honors; a Hugo would have given it a rare sweep of SF’s most prestigious awards
And Rebecca herself was there to collect it
Will there be more Alfies in the years to come
Lord Jago Branok is having a party at Loveday House
his lordship’s rambling mysterious (some say haunted) manse
perched on the cliffs overlooking the sea on Keun Island
Three miles of mudflats and an ancient stone causeway connect the rocky island to the Cornish mainland during low tide
but when the tide comes roaring in… fast as a galloping horse
as the locals say… the road is submerged and Keun becomes a true island
Archeologists have found Stone Age cairns there
and the jagged remnants of standing stones larger than any of those at Stonehedge
A ringfort stood atop the island’s sheer black cliffs during the Dark Ages; later a crude castle of rough-hewn stone went up in its place
For hundreds of years Keun was the stronghold of a clan of reavers and pirates known as the Hounds of the Sea
who raided and plundered up and down the Cornish coasts and into Wales and England
It was from them the island got its name; keun being Cornish for ‘hound.’ They were finally extinguished in 1308 by Piers Gaveston
who put to death every member of the clan and razed their castle
Legends claim that the last surviving hound pronounced a curse on Gaveston as he died
Thereafter the island remained uninhabited for several centuries
save for seabirds and an occasional fisherman
The fisher folk did not like to stay overnight
however; it was said the island was haunted
There were also tales of merfolk in the waters surrounding Keun Island; some stories spoke of beautiful mermaids who lured sailors to their doom
Humanity returned to the island in the 1500s
A new castle arose atop the cliffs on the seaward side of the island
and a fishing village on the landward side
Over the years half a dozen noble families came and went
The last and greatest of the lordly manors on Keun was called Loveday Castle
the widowed Lady Morwen (known as Mad Morwen) died during the Great Storm of 1703 as the castle collapsed about her
the ruins of Loveday were left to decay… until 1857
when a wealthy merchant styling himself Marcus St
pulled down the overgrown ruins of the old castle
a process that continued until the Great Depression
but found no buyers; the mansion had become a white elephant
Loveday was abandoned once more and left to rot
And so it did… until a new owner turned up and set about restoring the old house to its former splendor
The “new lord” is a mysterious figure who goes about in a hooded cloak
A dozen mutually contradictory tales are told of him in the village
but on one point the villagers agree: Jago Branok is a wild card of some sort
And the quests who visit Loveday each month are just as queer
They come to Keun from all over the world
Most of them leave after the party winds down
Stories told by the likes of Stephen Leigh
accompanied by their characters old and new
the latest volume in our long-running WILD CARDS series of mosaic novels
Volume thirty-four in the ongoing series (which launched way back in 1987)… and no
you don’t need to read the preceding thirty-three to enjoy this one… HOUSE RULES was released by HarperCollins Voyager in the UK in December
I am a few months late in getting out the word
For those of you who like autographed editions
Beastly Books in Santa Fe has signed copies of both editions in stock
(And they have many of the older volumes as well)
Whether you’ve been a Wild Cards fan from the very beginning
or are a newcomer curious to visit our world
Jago Branok’s parties are not to be forgotten… and who knows
This is not your occasional message from George or the minions of Fevre River
but a new addition to the team – I’m Michael Cassutt
Since October I’ve been working with George as his “creative director,” helping to shape and advance non-HBO TV
film and game projects and even some publishing
I’m not “helping” George with his writing.)
Last spring and early summer I directed a short film titled THE SUMMER MACHINE
based on a lost TWILIGHT ZONE TV concept by George
We shot for eight days in Alamagordo and Las Cruces
This is the fifth film that George has produced
following four adaptations of stories by his great friend Howard Waldrop: NIGHT OF THE COOTERS
MARY MARGARET ROAD-GRADER and THE UGLY CHICKENS
but difficult for even feature-length projects these days
Not only does this expose your work to an audience
but it opens the door to the holy grail of indie filmmaking
Our team started with NIGHT OF THE COOTERS
which had its premiere showing at the LA Shorts film festival in North Hollywood in August 2022
directed by and starring Vincent D’Onofrio
earned additional honors at Midwest Weird (Eau Claire
Since then we’ve released MARY MARGARET and THE UGLY CHICKENS
and both of them have picked up awards and made themselves known:
has been recognized by the deadCenter Film Fest and the Mojave Wasteland Film Fest
Steven was judged co-winner of the Russell Bates award
honoring the first Native writer of SF for television
written by me and starring the talented Felicia Day—
Felicia was chosen as best actress at the Yellowstone (India) Film Festival last fall
at the Pittsburgh Film Festival in December
This week is the Pendance Film Festival in Toronto
and UGLY CHICKENS has already won the Best Canadian Short Film
Cinequest in San Jose (March 22-24) and producer Elias Gallegos will be representing us at the Cleveland International Film Festival (late March-early April)
UGLY CHICKENS has been accepted at the Certain.e.s laiment court (CLAC)
And we’re nowhere near done with MARY MARGARET
which has been submitted to half a dozen upcoming festivals
(Typically we find out about acceptances three weeks ahead of time.)
My SUMMER MACHINE will be submitted for the first time this spring
I mentioning these events now because George and I and the team that made these films would like you to see them
too – and dozens of other great shorts and features at these festivals
We have a cover for the illustrated edition of the fourth book in my A Song of Ice and Fire series! This gorgeous, illustrated edition of A Feast for Crows will be arriving on shelves November 4
The special edition of A Feast for Crows features 24 original color illustrations from artist Jeffrey R. McDonald and a special foreword by Joe Abercrombie
the seven powers dividing the land have beaten one another into an uneasy truce
and carrion eaters of the Seven Kingdoms gather
many are the guests—but only a few are the survivors
We’ll be sharing a couple of the interior illustrations later this spring so you can see what Jeffrey R. McDonald has in store for A Feast for Crows. In the meantime, you can visit Jeffrey’s website to see examples of his previous work
Preorders are available now
THIS MESSAGE HAS BEEN BROUGHT TO YOU BY THE MINIONS OF FEVRE RIVER
The Saturn Awards were created in 1973 by the Academy of Science Fiction
to honor the year’s best work in genre television
They have been given annually ever since
This year’s year’s awards ceremony
was held in the Hilton Universal City in Los Angeles
HOUSE OF THE DRAGON had three finalists in the television division
EMMA D’ARCY was nominated as Best Actress in a Televsion Series
The show itself was up against AVATAR: THE LAST AIRBENDER
and PERCY JACKSON AND THE OLYMPIANS for BEST FANTASY SERIES
Our congratulations go out to Emma and Matt
It is an honor just to be nominated (as I’ve been told more times than I can count)
but they did outstanding work bringing Rhaenyra and Daemon to vivid life
I am pleased to say that HOUSE OF THE DRAGON itself did take home the prize
and claimed the Saturn for BEST FANTASY SERIES
Here’s the full list of finalists and winners for the year
for those of you who like to keep track of these things
https://www.saturnawards.org/
I was not able to attend the awards ceremony
especially if you grew up during Mercury and Apollo
I’ve managed to attend the Saturn Awards only once
where I went to one of their awards luncheons to represent BEAUTY AND THE BEAST
The big winner was Arnold Schwarzenegger
whose acceptance speech was short and very very funny
Looking back over the history of the Saturns between then and now
I was surprised to learn that GAME OF THRONES won six of them over its run
That’s six Saturns for GAME OF THRONES and one for HOUSE OF THE DRAGON
this was the first I’ve heard of any of these
The Saturns were broadcast this year (on Roko)
but that hasn’t been true for most of their run… but you’d think someone would have told us
Maybe all the trophies are lined up on a shelf at HBO somewhere
surrounded by all the other awards HBO has won over the decades
belated congratulations to Maisie and Peter and Emilia
to David Nutter and Alan Taylor and Miguel Sapochnik and all the other writers and directors who helped make GOT what it was… and to the cast and crew who worked beside them in 2015 and 2019

This article is part of the Research TopicExploring the biological pathways for Brain resilienceView all 9 articles
patients generally have photophobia and phonophobia and seek for environments with less sensorial stimulation
Present work aimed to quantify cortical partial directed coherence (PDC) of electroencephalographic (EEG) recordings from migraine patients and controls in occipital
and frontal areas with or without photic stimulation
Our hypothesis is that migraine patients with visual aura might have neuronal networks with higher coherence than controls even in interictal periods due to a predisposition in sensory cortical processing
Methods: Eleven adult women with migraine with visual aura (at least 48 h without previous attacks) and seven healthy adult woman were submitted to EEG recording in basal state and during photic stimulation
Results: When compared to healthy volunteers
migraine patients show different coherence profiles
Migraine patients had greater coherence than controls during the basal period (without photic stimulation)
showing predisposition for sensory processing in many frequency ranges
patients showed a decrease in cortical coherence while controls had an increase
Conclusions: When compared to healty subjects
migraineurs show increased cortical coherence before photic stimulation
This may be the expression of a resilience mechanism that allows migraineurs the interictal period
The PDC analysis permits to address a patient coherence profile
or “coherence map,” that can be utilized for management of the headache disorder or following up treatments
The aim of this study was to quantify the PDC between EEG recordings of occipital
and frontal cortical areas of migraineurs and health volunteers after photic stimulation
aiming differential connectivity among neuronal networks
migraineurs might show a stronger functional connectivity between occipital and adjacent regions due to predisposition and genetic background
All patients were clinically diagnosed with migraine according to the International Headache Society Classification
and were having an average of three attacks weekly
Patients were free of attacks in the 48 h that preceded the recording day (interictal phase)
The experiment was authorized by the Ethical Committee of Medicine School of São José do Rio Preto (FAMERP
process 140/2008) and by the Ethical Comitee from the Center of Health Sciences of Federal University of Pernambuco (UFPE
and subjects gave their written permission for the use of their data for scientific and teaching purposes
3 s during 9 Hz stimulation and 4 s after light is off
it was analyzed only epochs within the 9 Hz_4 period
10 s of EEG recording were taken in the basal period (before any stimulation)
Subjects remained with eyes closed during the whole experiment (that took approximately 11 min)
Ten seconds epochs were taken before any stimulation occurs (basal period)
Gray and black arrows indicate moments in which stimulation was turned on and off
Four trains of 9 Hz stimulation (3 s duration) were applied
10 s epochs including the basal and fourth stimulation period (9 Hz_4)
All neuronal networks were analyzed in diads
and coherence values of basal and stimulation period were compared within the same hemisphere
and the level of confidence was considered p < 0.05
the evolution of coherence in time was averaged among controls and patients in the 9 Hz_4 epochs
To test the influence of spurious and uncontrolled electric artifacts
two sets of patients were recorded in different places: five patients in a neurologic clinic near Santa Fé do Sul
Brazil and six patients in the Clinical Hospital of the Federal University of Pernambuco (HC-UFPE) in Recife
all results were compared only in subjects recorded in the same place
In the basal period, that is before any photic stimulation occurs, it was clearly seen that migraine patients have increased coherence in many neuronal networks when compared to the control group, especially in parietal to frontal and frontal to occipital networks (Figure 2)
Partial directed coherence of controls and migrainous patients in basal condition (no stimulation)
Patients had a general higher number of statistical significant coherence events when compared to controls
especially in parietal to frontal and frontal to occipital networks
Arrows indicate the direction of the network
All events were considered different if p < 0.05
When photic stimulation starts, controls present an increase in coherence, as it could be expected since light is activating brain perceptual and sensory networks, especially those involving the occipital areas. But patients showed a decrease in coherence, especially right frontal to parietal (F-P) and parietal to frontal (P-F) in both hemispheres (Figure 3)
Comparison between coherence values in healthy volunteers (diamonds
interrupted lines) and migraine patients (squares
solid lines) in EEG recordings from basal and photic stimulation epochs
It is shown data from frontal and parietal networks
Controls generally present an increase of coherence after photic stimulation
have greater coherence values in basal period but with a strong tendency of decreasing with photic stimulation (A,B
*p < 0.05 between patients and controls; †p < 0.05 between basal and stimulation in controls; #p < 0.05 between basal and stimulation in patients; Mann–Whitney test was used for each comparison
Standard variations were suppressed for clarity
This decrease of coherence in the 9 Hz_4 epoch compared to basal period was also seen in a supplementary group of six patients recorded in another equipment and different hospital (HC-UFPE
This decrease was seen in the networks P3-O1 (gamma range)
where neuronal network properties in female predispose this gender to migraine attacks
To check if our results could be simply mathematical or EEGraphic artifacts
Results show that the specific neuronal network in which this decrease in coherence after photic stimulation occurs may vary from patient to patient
but the phenomenon is robust and was clearly seen in our data
In a study with quantitative EEG analysis (QEEG), it was described a general increase in theta power in all cortical regions of migraineurs compared to non-migraine controls in a time free from pre-ictal symptoms (Bjørk et al., 2009)
we could identify an increase of coherence too
in theta frequency range of migraineurs compared to controls
It is possible that the increase in theta power described in that study could reflect a greater connectivity in this frequency range
but this can only be detected by PDC analysis
A future approach of our work is to repeat the experiment identifying what are the most responsive neuronal networks in each patient
and following the evolution in coherence during a treatment to compare if clinical signals can be correlated to a change in brain coherence
we imagine that this EEG analysis could be automated and be another tool for the clinician to readily categorize migraine patients within “EEG coherence maps” or profiles
establish the best approach and monitor treatment evolution
It is well-known that even those patients with similar clinical signals do not respond equally to treatments
so tools capable of identifying and categorizing patients (in this case

Dry weather across some of the major producing regions in South America is putting upward pressure on corn and soybean prices at the start the new year
Dryness is expected to continue through the short term across southern Brazil and especially in the main-producing states in Argentina
”We may see some recovery in rainfall in Brazil as we head into late January and February
this would be ill-timed moisture as harvest activities begin and the second corn crop (Safrinha) planting gets underway”
precipitation is forecast to continue to run at a deficit in southern Brazil and growing regions of Argentina
Weathertrends360 anticipated this will be the fourth driest first full week of January in 30 years for Rio Grande do Sul
and the third driest in 30 years for Santa Fe
The eastern region of Brazil will fare better with wetter-than-normal conditions expected
As we head into late January and February 2021
Weatrhertrebds360 expects that wetter weather will return to portions of southern Brazil
timing will be an issue as early harvest activities begin and planting begins for the Safrinha crop
Drier weather is more likely to continue in eastern Argentina

Fillets and cubes The pattern of fish consumption is also the subject of research
The most recent PIPE project coordinated by Hilsdorf was aimed at getting to know the consumer market for red tilapia and developing processed fish products
UMC and the Food Technology Institute (ITAL)
was started in 2011 and also received funding from the Brazilian Innovation Agency (FINEP)
produced fillets cooked in the form of cubes and fresh fillets with sauces similar to products found abroad
in the form of bags similar to those used in sauces and pastas
They can be eaten at meals or in the form of snacks
“We made cooked tilapia fillets cut into pieces with brine
the product is finished and ready to use,” says José Ricardo Gonçalves
There have also been several tasting sessions to assess consumer reaction
The cubed and cooked fillet had an acceptance rating of 70% and a rejection rate of 20%
Royal Fish will analyze which products are suitable for the market
Intense growth Rising production shows the importance of tilapia in Brazilian aquaculture
Tilapia is the most cultivated fish in Brazil
219,000 metric tons were caught (slaughtered and sold)
according to the Brazilian Institute of Geography and Statistics (IBGE)
This number increased by 9.7% compared to 2014 and almost 10 times since 1998
The largest producing regions are in Ceará
mainly in the municipality of Jaguaribara; São Paulo
in the cities of Santa Fé do Sul and Rifaina; in addition to Toledo
last year production amounted to R$1.177 billion
Chitralada tilapia is one of the most readily available varieties in Brazil; it has been in the country since 1996 and is a descendant of tilapia from Egypt that was imported to Japan and later improved in Thailand
which stands for genetically improved farmed tilapia
the result of a 10-year project (1988-1997) to produce a genetically superior variety of tilapia at the International Center for Living Aquatic Resources Management (ICLARM)
GIFT was introduced in Brazil in 2005 through a partnership between the State University of Maringá (UEM) in Paraná and the WorldFish Center
with the collaboration of the former Ministry of Fisheries and Aquaculture and Companhia de Desenvolvimento Agropecuário do Paraná (Codapar)
The Informativo Mercado da Tilápia [Tilapia Market Report]
indicates that Brazil exported 171 metric tons of fresh tilapia fillets to the United States in 2015
97% of Brazil’s total foreign tilapia trade
exports had already surpassed the 2015 figure

Photo: AuroraThe Brazilian cooperative Aurora will build a large
high-tech feed factory for poultry and pigs in Erechim
That was recently announced by the company’s livestock director Marcos Antônio Zordan
The unit will be placed at highway ERS-331
Rio Grande do Sul state is Brazil’s southernmost state – and together with Paraná and Santa Catarina
and is estimated to be completed by mid-2022
The new plant is planned to have capacity to produce 60 tonnes of feed per hour or 35,000 tonnes per month for both poultry and pigs
It means a 20% increase of their current feed producing capacity
The cooperative also plans the construction of 4 steel silos for grain storage in that complex
with a static capacity of 10,000 tonnes each
The total storage capacity of 40,000 tonnes would equal 660,000 sacks
Brazil: Records reached for chicken in 2021 Chicken production in Brazil in 2021 is forecast to increase by 4%
The unit will employ completely automated procedures using modern national and imported equipment including software
robotics and remote controls in order to produce the pellets
Still it is expected that the unit could create 80 direct and 240 indirect jobs initially and that might go up to 400 eventually
The plant will supply Aurora Cooperative’s integrated farmers in Rio Grande do Sul
that serve 3 slaughter and processing plants in Erechim (poultry and pigs) and Sarandi (pigs)
Those plants in Rio Grande do Sul finish about 1 million pigs and 26 million birds per year
The cooperative currently maintains 6 poultry and pig feed plants with a capacity of 175,000 tonnes per month
Aurora Alimentos has 7 pig plants processing 5.2 million head per year and 8 poultry slaughter plants
which slaughter 242.6 million head per year
These plants are located in Santa Catarina
