Drought-driven Pantanal wildfires and other climate change pressures
the team of wildlife rehab experts approach a cluster of trees and spot their quarry: A young giant anteater
sleeping on a hot morning with her luxuriant tail shading her head
She is a survivor of a fire holocaust that swept through Brazil's vast southern Pantanal in 2020, killing an estimated 17 million animals and burning nearly a quarter of the drought-parched wetlands and grasslands region
at an age when she should have been still clinging to her mother's back
the young anteater has since been cared for by Orphans of Fires
a project in Mato Grosso do Sul state that hopes to help her return permanently to the wild
Started in Aquidauana by conservationists in the wake of the fires
it now cares for 15 rescued giant anteaters
notes veterinarian Maria Helena Mazzoni Baldini approvingly - a sign the sleeping young orphan is fending for herself
though she was too young to learn foraging skills from her mother
more than 50 giant anteaters injured or displaced by the Pantanal fires were taken in by state rescue projects - a leap from 13 the previous year
according to Mato Grosso do Sul's Wild Animals Rehabilitation Center (CRAS)
As fires grow larger and more frequent and as global warming brings hotter and drier conditions
the already endangered anteaters - which also live in the Amazon rainforest - are coming under growing pressure
have led to their habitat shrinking in the Amazon and the Brazilian savanna
research coordinator for the Anteater Institute
believes the highly specialized animals are particularly imperiled
not least because they can struggle with temperatures extremes
The number of giant anteaters in Brazil has already fallen 30% between 1989 and 2015

Global temperatures have risen more than 1.2 degrees Celsius (2.2 Fahrenheit) since preindustrial times and are now swiftly approaching a 1.5C degrees of warming mark that scientists fear could herald a transition to far costlier and deadlier climate change impacts
set a goal of limiting global warming to "well below" 2 degrees Celsius (3.6 Fahrenheit) while "pursuing efforts" for 1.5C
But with fossil fuel use still rising globally
1.5C of warming could be passed within a decade
They fear that could trigger irreversible ecological tipping points
from surging sea levels as polar ice melts to spiking temperatures as methane - a potent driver of warming - escapes thawing permafrost
A hotter planet is also expected to spark more extreme weather
migration and soaring personal and financial losses for many people around the planet
Brazil's forests, savannas and wetlands contain the richest mix of plants and animals in the world. But many of those species are at growing risk of extinction as their habitat vanishes and climate impacts worsen
Such potential losses present a danger not just for the species and ecosystems themselves but for millions of people who depend on them for everything from food to reliable rainfall and innovative medicines
"Most people are completely oblivious to how biology supports their lives
They are completely oblivious to the biological origins of a medication when they go to get a refill at the pharmacy," biologist Thomas Lovejoy
who coined the term "biological diversity"
"Biodiversity is a living library of 4 billion years of evolution
with each organism and species daily working on biological challenges and solutions in their own existence
It's a pretty powerful way to generate a lot of knowledge," said the scientist
who worked much of his life in the Brazilian Amazon

Their probing tongues - up to 60 centimetres (23 inches) long - leave long lines of thick saliva on their carers' clothes and skin
"It has to be gluey so the ants stick to it"
With a limited high-protein diet of insects in the wild
the animals' metabolism has evolved to be relatively slow
with their average body temperature around 34 degrees Celsius
Anteaters in the Pantanal forage mainly in open fields
and hotter days there mean many are on the move fewer daylight hours and need more often to seek trees for shade and rest
something increasingly difficult as more trees are burned or cut
The Pantanal's average temperature has risen 2 degrees Celsius since 1980
according to Brazilian research institutions and data from the U.S
National Centers for Environmental Information
A 2020 study in the journal Nature estimates it is one of the areas in South America with the highest percentage of species at risk from climate change
a Brazilian biodiversity researcher at the University of Cape Town
said more frequent and severe weather extremes are leaving many stressed species with little time to recover between crises
are also affecting the Pantanal's supply of water
water vapor rises from the moist Amazon forest and is blown toward southern South America
According to data from the nonprofit MapBiomas
the area of the Pantanal covered by water during the height of seasonal floods has shrunk by 29% between 1988 and 2018
ranching has been the most common agricultural activity in the vast wetland
from the Pantanal branch of the state-owned Brazilian Agricultural Research Corporation (EMBRAPA)
said cattle ranching also is becoming more destructive as once-vast farms are divided between heirs or sold in smaller plots
tree areas are converted to pasture and native grass are replaced by exotic varieties
95% of the biome’s areas in Mato Grosso do Sul state is on private land
The Orphans of Fire is located on one of those private farms
owned by João Ildefonso Pinheiro Murano
who runs 2,400 head of cattle there and operates a hotel
even he concedes that "I have never seen a drought like this one"
tourists would be visiting a pond called Poção on his property

But this year water that was once shoulder-high in the pond has vanished

At the center of the pond one last starving caiman lingers

It is almost completely still except for the occasional blinking of its eyes

Researchers find a 1000 km2 lake hidden under aquatic plants on the plains of the Rio Negro
geologists and geographers from Brazil and abroad have studied the landscapes that form the Rio Negro’s plain in the south of the Pantanal
without realizing that it was home to a large lake hidden beneath a huge mat of aquatic flora
In a paper published in the scientific journal Earth Surface Processes and Landforms in October
researchers described the discovery of a lake that is just over two-thirds of the size of the city of São Paulo
“It was almost impossible to identify it at first sight,” says geographer Eder Renato Merino
a postdoctoral fellow at the Institute of Energy and Environment at the University of São Paulo (IEE-USP) and one of the authors of the study
“The accumulation of floating mats and meadows on its surface makes it appear from afar like an area of land covered by grass.”
Merino was one of the researchers who identified the lake
The finding was made thanks to satellite image analyses that he conducted during his PhD
which he completed in 2016 under the guidance of geologist Mario Luis Assine
from the Institute of Geosciences and Exact Sciences at São Paulo State University (UNESP)
Assine has been studying the transformations that affect the landscapes of the Pantanal
one of the largest floodplains in the world
he and Merino were looking at how the plains of the Rio Negro were formed and how water and sediments were captured and distributed in the region during the flood season between October and May
Eder Renato Merino An accumulation of floating aquatic plants forms a mat that covers the surface of the lakeEder Renato Merino
The lake is thought to be 3 to 4 meters deep
with the water level varying across the dry and wet seasons
Its bed is composed of a thick layer of fine sand and mud enriched with organic matter formed of decomposing plants
it is supplied by the waters of the Negro and Aquidauana rivers
the Aquidauana is primarily responsible for carrying sediment into the lake
much of the Rio Negro’s sediments remain trapped on the higher grounds through which the river passes before it reaches the plain
The researchers also examined the plants that cover much of the lake’s surface and found that they have long roots that spread below the waterline. Transported by the rivers, these plants accumulate on the surface and in many cases form islands of vegetation in the flooded area. Some of these islands are being colonized by pioneer plant species, capable of establishing themselves and multiplying rapidly in harsh environments.
Eder Renato Merino Channel through which the Aquidauana River flows is made of the sediment that accumulates on its banksEder Renato Merino
the study also makes it even more evident that the lake systems in the Pantanal are not all formed by the same processes
“This ‘hidden lake’ on the plain of the Rio Negro was created by completely different geological
and climatic processes than those that gave rise to the lakes in Nhecolândia
near the municipality of Corumbá in the state of Mato Grosso do Sul
even though these two regions are very close to each other,” says the researcher
the Nhecolândia lakes are the result of depressions shaped by the accumulation of fine sand carried by the wind in dry periods of the late Pleistocene
“Those of us studying the Pantanal are constantly surprised by new discoveries,” says Assine

Background: A tribe of Indians near Aquidauana
was examined applying the DMFT and DMFS indexes
Methods: Data was recorded utilizing the DMFT (decayed
Observations were made through visual means
utilizing natural sunlight and a small flashlight
100% had caries with a mean DMFT score of 11.7 and a mean DMFS score of 23.6
The percent of teeth affected by decay ranged from 10% to 85%
The percent of surfaces affected by decay ranged from 2% to 63%
Forty-three (52%) students had ≥25% decayed surfaces and 48 (58%) students had ≥50% of total (counted) teeth with decay present
Conclusions: Dental caries are incredibly prevalent in this population of young tribal Indians
or regular preventive checkups with dental professionals
the condition of these tribal members is not likely to improve in the future
Introduction: What would you do if every student in your child's class had untreated dental decay
What if access to toothpaste and fluoridated water was out of the question
----------------------------------------------------------------------
This is the reality tribes face every day in many parts of the world
A local church in Michigan took a group of college-aged students down to Aquidauana
and Bible lessons with the children of a tribe that live about an hour outside the city
I embodied the tooth fairy giving presentations before hundreds of students in classrooms
My interest continued when I decided to survey in what condition I might find their dentitions
With a small sample of 83 children and interviewing teachers about life in the tribe
I gained valuable insight into dental life in third-world conditions
Objectives: To calculate and present the prevalence of dental caries in a group of 83 children to determine what condition the average dentition of a child would be with no exposure to fluoride or preventive treatment
Methods: Data was recorded utilizing the DMFT and the DMFS indexes
Due to children possessing mixed dentition
only the primary teeth were evaluated.1 The figures conveyed in the primary dentition are five surfaces for a posterior tooth (buccal
and occlusal) and four surfaces for anterior teeth (facial
utlizing natural sunlight and a small flashlight
The smallest percent of teeth affected by decay was 10%
means there were two decayed teeth in this child
which was the saddening minimum quantity for a community
The highest percent of surfaces affected by decay was 63% on a six-year-old boy
Fifty-five surfaces and 13 (of the 20 counted) teeth in his mouth were rotting
Discussion: This study discloses a high caries involvement in children of this tribe
I sat down with a translator and a few teachers from the schools to find insight into habits that affect the dental health of the tribal children
Mixed answers came to the inquiry: "Do the children ever complain of toothaches?" One teacher never encountered the situation
Others stated the students do not complain specifically to the teachers because they know the teachers do not have the materials to help
and another stated the teachers do not care
the instructors tire of hearing a problem they have no means to solve
the children stated they brush their teeth on multiple occasions throughout the day
why do these children still have so many cavities
One felt it was the lack of incentives and education
one thought it was the lack of other home aids (such as toothpaste)
but once a month a dentist comes to do fillings
is only for the children who have employed parents
The teachers indicated that the children eat sweets
which in combination with inferior or absent preventative methods
Conclusion: Results reveal that dental caries are incredibly prevalent in this young population
The Egyptians as early as 5000 BC created a powder to clean teeth that consisted of powdered ashes of ox hooves
and pumice.3 These were natural ingredients found in their immediate surroundings
a natural knowledge to clean the oral cavity and demonstrates how modern marvels have humble beginnings
Perhaps given the knowledge of what their natural resources can provide
dental health can make small advances in this and other tribes over time with the correct resources
we should strive for more outreach programs and sponsorship to various countries to make fighting dental decay a global effort

Volunteer firefighter members of the Alto Pantanal Brigade works to extinguish a fire rising in the Pantanal in Corumba
Climate change makes wildfires in the Pantanal - between Brazil
Bolivia and Paraguay - more likely and worse
RIO DE JANEIRO - More than 1.3 million hectares of natural vegetation have burned in South America's Pantanal this year already, with images of incinerated jaguars
The burnt area amounts to nearly 9% of the Pantanal
according to data released last week by the Laboratory for Environmental Satellite Applications from the Federal University of Rio de Janeiro.
The peak of this year's fire season is yet to come, with environmentalists fearful that 2024 might see record levels of destruction, only four years after the last record season, which killed half the area's jaguar population
Volunteer firefighter members of the Alto Pantanal Brigade are seen on a tractor as they work to extinguish a fire rising in the Pantanal
A fisherman sails through the Paraguay River as smoke rises into the air from the fire in the Pantanal
Spanning 179,300 square km (44.3 million acres) - about the size of Uruguay - the Pantanal is formed by a mosaic of wetland and other ecosystems including forests
most of which are located within Brazil (78%)
followed by Bolivia (18%) and Paraguay (4%).
Although most of the Pantanal is covered by private farms, with cattle ranching its main economic activity, part of the territory is still controlled by Indigenous and other traditional riverside populations
It is a biodiversity hot spot, with many of its species also found in other South American biomes, such as the Amazon forest and the Cerrado tropical savannah
With more than 600 different species of birds, more than 100 species of mammals and 170 species of reptiles, the Pantanal is known for its abundance of wildlife, making it a common ecotourism destination
However, much of its fauna is on the red list of threatened species compiled by the International Union for Conservation of Nature, including the giant anteater
Brazil's National Institute for Space Research detected 4,756 fire episodes in the Pantanal in the first seven months of this year
Although the Pantanal's dry season typically occurs from July to October, this year's fires started to gain strength as early as May
Bolivia has also registered a record number of fires for the same period
while Paraguay had its fourth highest record
Up until now, figures are even worse than those from 2020's historical fires, when about a third of the Pantanal's area suffered blazes, killing an estimated 17 million vertebrates
Peak fires are expected in the coming months
The Pantanal has been warming at a faster pace than the global average
with a 2ºC increase in its average temperature since the 1980s
In addition to global warming, this year's extreme drought has been made more intense by the El Niño climate pattern, climatologists say, but the Pantanal has been losing water for years, without a major flood since 2018
According to data released in June by MapBiomas, a collaboration between Brazilian universities, nonprofits and tech firms, the Pantanal has lost about 81% of its surface water since 1985
told reporters the biome had previously experienced extreme dryness in the 20th century
but said now less than 40% of its river springs were protected by natural vegetation
Only 4.7% of Brazil's Pantanal is protected by reserves
with environmentalists warning that grain farming is expanding
Although fires are a part of Pantanal's natural cycles, with many of its plants resistant to low intensity flames, only about 5% of the fires are thought to have natural causes
Most of the fires are started by farmers to renovate pastures or finish converting natural areas into farmland after the trees have been felled
This year's fires are concentrated in Corumbá municipality in Brazil, which also has the highest deforestation rates in the Pantanal.

From Greek holiday islands to Canada's temperate forests
wildfires are intensifying as climate change fuels rising temperatures
Is it possible to conciliate jaguar conservation with cattle ranching activity
To involve cattle ranchers in this conservation goals
WWF-Brazil and the NGO Pró-Carnívoros organized a meeting by the end of May
The event was attended by Pantanal’s traditional cattle ranchers
as well as by federal and state patrolling/inspection organizations
such as the environmental police and The Brazilian Agricultural Research Corporation (Embrapa)
The technology can recognize individual cattle with 99.8% accuracy
Efforts by researchers from Mato Grosso do Sul to save an endangered breed of cattle in the Pantanal could result in a technology capable of making life easier for cattle breeders in general
Having created a system that uses artificial intelligence (AI) to individually recognize Pantaneiro cattle based solely on images with an accuracy of up to 99.8%
incubated at the Dom Bosco Catholic University (UCDB) in Campo Grande
is now working on adapting the algorithm to other more common breeds
The aim is to provide an alternative to traditional identification methods
saving livestock farmers time and money and reducing animal suffering
The technology was initially created by computer scientist Fabrício de Lima Weber
during his master’s degree at the State University of Mato Grosso do Sul (UEMS)
He used a set of computational techniques specifically for image processing and analysis
inspired by biological processes that occur in the human visual cortex
known as convolutional neural networks (CNNs)
A study involving Pantaneiro cattle found that the architectural model of a CNN can be used in a computer vision system designed to automatically recognize the animals. The process is similar to human facial recognition systems already used in several countries on public transport and in stadiums and airports (see Pesquisa FAPESP issue nº 274)
where people are identified by comparing images to an existing database
but also characteristics of the animal’s back
carried out under the supervision of veterinarian Urbano Gomes Pinto de Abreu from EMBRAPA Pantanal
and the collaboration between researchers from the UEMS Pantaneiro Cattle Conservation Center in Aquidauana (NUBOPAN)
and the Federal University of Mato Grosso do Sul (UFMS)
was published in the journal Computers and Electronics in Agriculture in 2020
“The system went through a maturation process
We adopted new technologies that are faster and require less processing power,” says Weber
To populate the database for the Pantaneiro cattle
the researchers used four cameras placed at different locations in a corral
The cameras took thousands of pictures of a herd of 51 cattle
a camera equipped with special software was able to individually identify each animal in the group within just a few seconds (see infographic below)
Rodrigo CunhaAutomatic visual recognition of the cattle facilitates herd management
allowing the history of each animal to be tracked and ensuring traceability
Information such as an animal’s location of origin
and feed type are all available to potential buyers and suppliers
reducing the risk of irregularities in the production and sales processes
Various computational architectures using CNNs and deep learning have already been used in studies to identify diseases in plants
classify marine organisms and objects found in the ocean
little research into identifying cattle using this technology
“Studies on visual identification of cattle are being conducted around the world
The ones we know of use technology supported by more advanced cameras
while some aim only to identify the faces of the animals
which makes the process more difficult,” says Weber
especially with zebu cattle like the Nelore breed
the animals rarely stand still for long enough to obtain a facial image
This is the biggest challenge: achieving not just facial recognition
but identifying cattle based on other characteristics while they’re in the pasture or corral,” explains Abreu
The team from Mato Grosso do Sul intends to make the technology accessible to everyone
from the largest companies to the smallest ranchers
and for it to work in the field even without an internet signal
Data could be accessed via an intranet or using a system based on wireless communication protocols such as bluetooth
“We want to reach not just major producers
The unique aspect of our system is the cameras
which are much more accessible and cheaper,” says Weber
EmbrapaThere are only about 500 purebred animals left in the country
a veterinarian and livestock breeder from Rio Verde in Mato Grosso do Sul
is eagerly anticipating the results of the research
especially by saving time spent identifying animals.”
animals have to be held in a cattle chute to be branded with a hot iron or have a tag or collar fitted
which requires significant time and manpower
“Identifying animals by image would be great because then they wouldn’t need to be contained and marked individually
The camera alone would do the job while the cattle are in the pasture,” he says
Bezerra claims the technology could also offer economic and health advantages
Although the products conventionally used for animal identification have a low unit value
Remote visual recognition would also eliminate some common problems
The KeroW team does not yet know when the new technology will be launched on the market
“We’re relying on investments to complete the product,” says systems analyst Vanessa Aparecida de Moraes Weber
one of the startup’s founders and a technician at UEMS
“The company recently won funding to develop a solution for Girolando cattle through a public call for proposals issued by the CNPq [Brazilian National Council for Scientific and Technological Development]
We are submitting the project to other programs in search of further funding to purchase the equipment needed to continue our research.”
“What makes my PhD research different is that we use 2D cameras with RGB sensors [which capture color images
and easier to maintain,” Venessa Weber says
we want to utilize the mass estimation functionality to make certain decisions
including the right time to slaughter an animal
It will also be possible to categorize animals and automatically classify them according to their weight gain.”
The Pantaneiro breed was first created from the crossbreeding of 11 Portuguese and Spanish breeds brought to South America by colonizers in the sixteenth and seventeenth centuries
the breed adapted to the local environment and climate conditions
such as seasonal floods and prolonged droughts
and 14 other potentially distinct features
uncontrolled crossbreeding with other breeds
has led to near extinction of the Pantaneiro cattle

recorded over 2,300 fire outbreaks during the first days of November
a scenario that worsened due to drought and intense hot weather
The states of Mato Grosso do Sul and Mato Grosso
declared state of emergency in many cities.
According to data collected by the National Institute for Space Research (Inpe
the figures are five times the average for November
The decrees the two state governments published include the cities of Aquidauana
and all the area of Mato Grosso state.
The fires started in October and surpassed 35,000 hectares
Over 70% of this area is part of the Negro River State Park
The fires also reached Pantanal National Park
the Dorochê Private Natural Heritage Reserve and the Meeting of Waters State Park
the local governments mention the lack of rain and the extreme hot weather as boosters to the current situation
The emergency scenario made it possible to transfer resources to the states and call for the support of federal civil defense.
The work to put out the fires is being affected by strong winds in the region and difficulties accessing the areas
the Brazilian Institute of the Environment and Renewable Natural Resources (Ibama
in Portuguese) announced efforts to extinguish the fires and support the states.
Almost 300 wildland firefighters (known in Brazil as “brigadistas”) and federal employees are working on the site
The operation uses four airplanes and another two may be sent to support the actions
Ibama and the Chico Mendes Institute informed they will deploy more brigadistas to the area.
