Vast numbers of Yacare caiman congregate in Brazil’s Pantanal wetlands, representing perhaps the largest single crocodilian population in the world.
In the past few years, however, the number of caimans has dwindled to just a few dozen individuals, according to a new study published in PLOS ONE by researchers from the National University of Rio de Janeiro (UFRJ) and the Brazilian Institute of Ecology and Natural Resources (INPE).
The researchers found that the population has declined by more than 90 percent since the 1970s, and that it is likely to continue to decline as a result of habitat loss, hunting, disease and human encroachment.
The study was conducted in collaboration with the U.S. Fish and Wildlife Service (USFWS), the International Union for Conservation of Nature (IUCN) Red List of Threatened Species (RTS) Species of Special Concern (SSC) as well as the World Wildlife Fund (WWF), and was funded by a grant from WWF-Brazil.
