Researchers have compiled over 154,000 records of camera trap images from the Amazon Rainforest, identifying 317 different bird, mammal, and reptile species.
This is the first study at this scale to compile and standardize camera trap images from across the Amazon, and it includes Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela.
According to the authors, this camera trap data set allows for new studies on forest fragmentation, habitat loss, climate change, and human-caused animal loss "in one of the world's most important and threatened tropical environments."
Wildlife crawls, hops, flies, and prowls through every nook and cranny of the world's largest rainforest.
However, because most animals are good at hiding from humans, finding them can be difficult.
Many researchers rely on camera traps to accomplish this, which are motion-sensing, often camouflaged cameras strategically placed throughout the forest.
Scientists have been collecting camera trap images across the Amazon for decades, but the data has been dispersed until now.
A group of researchers compiled over 154,000 camera trap images, capturing 317 species: 185 birds, 119 mammals, and 13 reptiles.
The new data paper, published in the journal Ecology, was led by the German Centre for Integrative Biodiversity Research (iDiv) and Friedrich Schiller University Jena and draws on records from 147 scientists representing 122 research institutions.
This is the first study at this scale to compile and standardize camera trap images from across the Amazon, and it includes Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela.
"The dataset provides basic information about species presence and abundance in the forest and can be used to answer questions on an Amazon scale," said Ana Carolina Antunes, the study's lead author, in an email to Mongabay.
The study's co-author, Robert Wallace, director of the Wildlife Conservation Society's (WCS) Greater Madidi-Tambopata Landscape Program, said in a statement that the thousands of images "will serve as critical data points to show where wildlife occurs and the staggering diversity of species found in the Amazon region."
WCS provided images of jaguar cubs playing, a giant anteater wallowing in the mud, short-eared dogs, tapirs, crested eagles, toucans, pumas, and Andean bears.
According to the authors, this camera trap data set opens up opportunities for new studies across broader time scales and areas, allowing scientists to learn more about forest fragmentation, habitat loss, climate change, and human-caused animal loss "in one of the world's most important and threatened tropical environments."
"It will be possible to understand patterns of species distribution in their habitats, interactions between predator and prey species, and make future projections about the impact of climate and land-use change on the species," Antunes explained.
"There is still so much to learn while also facing an increasing threat to biodiversity and the people who live in the forest."
According to Global Forest Watch, more than 3.7 million hectares (9.1 million acres) of primary tropical forest were lost globally in 2021, with Brazil accounting for 40% of that loss.
The Brazilian Amazon accounts for nearly two-thirds of the Amazon Rainforest and one-third of tropical rainforest cover worldwide, making it critical for preserving Earth's biodiversity.
