Why the research is important

The Araguaia River is one of the best remaining options for providing a protected wildlife corridor to preserve Brazilian biodiversity.

A fragmented agricultural landscape presents a threat to the biodiversity of Brazilian wildlife.

Fragmentation of habitats and isolation of small populations of animals threaten biodiversity. Small populations face greater risks of extinction, as they suffer from reduced genetic diversity, and inbreeding makes them less adaptable to changing conditions and more vulnerable to illnesses.

Habitat corridors provide individual animals with the opportunity to move between habitat patches, thus supporting genetic exchange and biodiversity conservation. Animals of the Cerrado are suffering from the effects of habitat fragmentation and population isolation. The Araguaia River, connecting the fragmented Cerrado and the Amazonian rainforest, is one of the best remaining options for providing a protected wildlife corridor to preserve Brazilian biodiversity.

White-lipped peccaries, Brazil

Monitor animals like these peccaries.

The challenge of the Araguaia River Biodiversity Corridor Program (ARBC) is to preserve the course of the Araguaia River and promote it as a biodiversity corridor. This project is investigating the movements of jaguars, pumas, maned wolves, tapirs, giant anteaters, giant armadillos, white-lipped peccaries, and rheas across the agricultural landscape around Emas National Park. This is particularly important with the rapid expansion of sugarcane cultivation in the Cerrado, which is further fragmenting the land and possibly creating barriers to wildlife movement.
