World’s largest known turtle nesting site found in the Amazon #Science #Biology #Ecology #TurtleConservation #AmazonRainforest
purescience.news/article?id=93

Pure Science NewsWorld’s largest known turtle nesting site found in the AmazonResearchers from the University of Florida have uncovered the largest known nesting site for the threatened giant South American river turtle (Podocnemis expansa). How did they find over 41,000 nesting reptiles? By deploying a meticulous squadron of drones. The turtles were found gathered along the Amazon’s Guaporé River between Brazil and Bolivia. This innovative use of drones opens up new avenues for conservationists, as detailed in a study recently published in the Journal of Applied Ecology. “We describe a novel way to more efficiently monitor animal populations,” study co-author and University of Florida ecologist Ismael Brack said in a statement. “And although the method is used to count turtles, it could also be applied to other species.” Researchers from the New York-based Wildlife Conservation Society (WCS) have been monitoring the giant South American river turtle in Brazil, Colombia, and Bolivia for several years. Also known as the Arrau turtle, these freshwater reptiles live in rivers and lakes along the Amazon and Orinoco River basins. Some can have shell lengths up to 35 inches long and weigh upwards of 130 pounds. They are omnivorous, eating leaves, seeds, and fruit, hunting for crabs, shrimp, and fish, and also scavenging for dead fish. Arrau turtles’ primary threats include poachers who sell their meat and eggs, habitat loss, dams, and pollution. These reptiles are also considered exceptionally social. Every year in July or August, female Arrau turtles gather to nest in the Guaporé River’s sandbanks between Brazil and Bolivia, and last year, a joint team from the University of Florida and WCS set out to count just how many come to nest. It’s a monumental task in this part of the Amazon, that’s home to jaguars, the Bolivian river dolphin, giant armadillos, and numerous other species.  [ Related: Why do turtles do the ‘Superman pose’? ] The University of Florida researchers met with WCS scientists at a conference and shared with them how they use drones to count turtles in and around Florida. With the imagery from the drones, the University of Florida team creates orthomosaics—highly detailed, high-resolution composite images made by stitching together hundreds of overlapping aerial photos. Tallying the animals shown in the orthomosaics is often a faster, more accurate, and less invasive method than simply counting the animals from the ground. However, orthomosaics don’t account for animals that sometimes move during observation periods. To solve this, the team developed a new method that improves counting accuracy by eliminating multiple sources of error. These include when the same individual animal is counted multiple times (called a double count) and missed individuals. The team used white paint to mark the shells of 1,187 turtles that gathered on an island sandbank within the Guaporé River. Over 12 days, a drone flew overhead on a steady back-and-forth path four times per day, taking 1,500 photos each flight: That’s 6,000 photos per day. Using a photo software, the researchers stitched the photos together. Drone footage captures the turtles at their nesting site on the Guaporé River’s sandbanks between Brazil and Bolivia. CREDIT: University of Florida/Brack et. al 2025. They then carefully reviewed each composite image, noting if a turtle’s shell was marked and whether the animal was walking or nesting when it was photographed. With this data in hand, they developed probability models that account for the turtles entering and leaving the area, the observed turtle behaviors, and the likelihood of detecting an identifiable shell marking. According to the team, the models revealed several sources of error that could arise from traditional orthomosaic-based counts. For example, only 35 percent of the turtles that used the sandbank were present during the drone flights. On average, 20 percent of those detected walking appeared multiple times in orthomosaics. Some individuals were spotted as many as seven times—don’t say turtles don’t get around. The observers positioned on the ground counted roughly 16,000 turtles. Those who reviewed the orthomosaics—not accounting for animal movement or shell markings—counted about 79,000 turtles. Once the new statistical models were applied, the study estimated that about 41,000 turtles were at that one site. “These numbers vary greatly, and that’s a problem for conservationists,” Brack said. “If scientists are unable to establish an accurate count of individuals of a species, how will they know if the population is in decline or whether efforts to protect it are successful?” The study also details ways to adapt and apply this technique to conservation efforts with other species that are monitored and surveyed using drone-derived orthomosaics. Past monitoring studies have involved clipping seals’ fur to make markings, attaching high-visibility collars to elk, and using paintball pellets to mark mountain goats to keep track of animal movement during counts. The team plans to perfect their monitoring methods by conducting more drone flights at the Guaporé River nesting site and in other South American countries where the giant South American river turtles gather. These include Colombia and possibly Peru and Venezuela, according to Brack. “By combining information from multiple surveys, we can detect population trends, and the Wildlife Conservation Society will know where to invest in conservation actions,” he said.

AvaazLula: A veto for the Amazon!I just signed a petition to stop Brazil's 'devastation bill' – a reckless law that opens the Amazon to destruction. Lula has the power to veto it – let's show him the world is watching. Join me and share

It's kinda sad that, when I typed "Amazon" into my phone a while ago, the first suggested following words didn't include "Rainforest", which was exactly the word I wanted.

The word too often is linked to the brand.

I just hope kids are still taught about the rainforest, because that one is more critical to life, and some humans only see its value as chopped wood, or cleared land.

An Action Plan for Amazon Droughts: The Time is Now!

The fertile lungs of our planet, the Amazon jungle faces severe drought due to El Niño, climate change, and deforestation for agriculture like palm oil, soy and meat. This along with gold mining, affects biodiversity and local indigenous communities. To combat this crisis, stronger measures against deforestation and illegal mining are essential. Global and local leaders must act now to protect the Amazon. #BoycottPalmOil #BoycottGold4Yanomami #Boycott4Wildlife.

The drought plaguing the Amazon is a worrying portrait of the climate challenges facing the world. The combination of the El Niño phenomenon and anthropogenic climate change has played a significant role in accentuating this extreme weather event. The Amazon region, known for its lush rainforest and flowing rivers, is facing a critical situation due to a lack of rainfall and rising temperatures.

This phenomenon, never recorded at this intensity, has affected biodiversity and human life in eight Amazonian states. The drought has already killed more than 140 dolphins, including pink dolphins and tucuxis, also known as grey dolphins. The mortality of fish and other aquatic animals is also high. The low volume of the rivers affects the human supply, causing a lack of drinking water and food in all the small villages, even those located on the banks of the big rivers. Of the 62 municipalities in the state of Amazonas, 42 are in a state of emergency, 18 are in a state of alert and only two are in a normal situation.

The El Niño phenomenon has a direct influence on the Amazon drought. It manifests itself in the abnormal warming of the surface waters of the Pacific Ocean, affecting the rainfall regime in various parts of the world. In the case of the Amazon region, the drought is exacerbated by a decrease in humidity and a lack of rainfall, damaging the vegetation, fauna and local communities that depend on natural resources.

However, anthropogenic climate change is making the situation even worse. Rampant deforestation, driven by agricultural expansion and logging activity, reduces the Amazon rainforest’s ability to regulate the climate and retain moisture. In addition, the destruction of vast areas of vegetation contributes to rising temperatures, creating a cycle of even more accentuated droughts.

Deforestation and gold mining, major factors

Deforestation has been particularly devastating in the region of Highway BR-319, in the south of Amazonas state, driven by land grabbing which has provided cheap land to cattle ranchers from other states. In turn, this deforestation has increased the number of fires that feed back into the climate crisis. When they occur near riverbanks, deforestation also intensifies the phenomenon known as fallen land, which has drastically affected the draught of rivers and is already significantly jeopardising navigation and logistics, mainly affecting villages in the interior of the Amazon, which are already suffering from shortages.

Another factor that has played a significant role in affecting navigation is gold mining activity. Disorganised mineral extraction has created banks of land that are harmful to navigation and which, in the critical scenario of drought, have caused many vessels to run aground.

The impact of hydroelectric dams

Hydroelectric dams also play a role in contributing to the drought scenario, especially on the Madeira River. This is mainly due to the decomposition of organic matter in reservoirs created by dams, which releases methane, a potent greenhouse gas, into the atmosphere. In addition, deforestation associated with the construction of dams, as well as soil degradation and erosion resulting from the alteration of aquatic and terrestrial ecosystems, can increase emissions of carbon dioxide (CO2) and other pollutants, contributing to the impact of hydroelectric dams on climate change.

The Madeira River, now at its lowest level in almost 60 years, has been drastically affected and transformed by the Jirau and Santo Antônio hydroelectric dams. This was due to the drastic alteration of the river’s natural flow caused by the damming of water for power generation. When water is dammed, a reservoir is formed that retains part of the water that would normally flow along the river. This diversion of the flow directly affects the region’s aquatic and terrestrial ecosystems, since the basin’s hydrological cycle is interrupted. The reduction in the volume of water in the Madeira River, for example, can lead to prolonged periods of drought, affecting not only aquatic fauna and riparian habitats, but also local communities that depend on the river for their livelihoods.

In addition, the construction and operation of hydroelectric dams in the Amazon often involves the clearing of significant areas of forest for the construction of dams and associated infrastructure. Deforestation contributes to a reduction in evapotranspiration, which is a crucial process for water balance in the region. With fewer trees to release water into the atmosphere, the Amazon becomes more susceptible to drought. The combination of these factors results in a significant impact on the region, making hydroelectric dams one of the causes of drought in the Amazon, particularly on the Madeira River, with worrying environmental and social consequences.

What can still be done

In order to combat the extreme drought in the Amazon and its devastating effects, it is essential to adopt strict measures to curb deforestation and illegal mining in the region, and for the federal government to review major undertakings such as hydroelectric dams and roads, such as the BR-319 motorway.

Many politicians have argued that the road, if paved, could reduce the state’s isolation, especially during droughts. However, this is a fallacious argument, because connecting the most isolated municipalities would require hundreds of kilometres of side roads, which would further increase deforestation and aggravate the climate crisis.

In addition, the BR-319 motorway has become a spearhead that cuts through one of the most conserved blocks of forest, linking the central Amazon, which is still preserved, to the “arc of Amazonian deforestation”, a region that concentrates most of the climate anomalies in the entire biome.

Ecosystem on the edge

In a recent study published in the renowned journal Conservation Biology, it was shown that deforestation in the Amazon is already impacting ecosystem services that are essential for Brazil, such as the Amazon’s flying rivers. This scientific data shows that we are already at the threshold of deforestation and environmental degradation tolerated by the Amazon, and more forceful action needs to be taken now.

Part of this responsibility lies now in the hands of President Lula, in reviewing major developments in the Amazon, such as hydroelectric dams and highways like the BR-319. In addition, it is essential to institute a zero deforestation policy that should begin this year, and not in 2030, when it will be too late. Furthermore, it is crucial that the international community and local governments work together to reduce greenhouse gas emissions and tackle climate change effectively. Only with coordinated and decisive action will we be able to mitigate the impacts of drought in the Amazon and protect this unique ecosystem that plays a vital role in regulating the global climate.
