SUMMARY:

The Atlantic Forest is an essential biome for the conservation of primates, mammals with the largest number of endangered species. The main threats that cause the extinction of these species are climate change and habitat loss. In this context, we aim to answer two questions in this work: (i) are protected areas efficient in representing climatically suitable areas for primates of the Atlantic Forest? and (ii) knowing that the geographic distributions predicted by the climate of these primates will change, how is the forest cover in the areas of congruence between the current and predicted geographic distributions for the future of these species? We compared the current and future suitability for primates of the Atlantic Forest within the protected areas (UC) with that within the geographic distributions. To answer the second question, we calculated forest cover in areas exclusive to the current distribution of species (EA), areas of overlap between current and future distribution (INT), and exclusive areas of the expected distribution for species in the future (EF). The capture of suitability values was higher in the current climate, where the conservation units (UC, UCPI, and UCUS) captured the highest available suitability values. There was a concentration of low suitability values in future climate scenarios, possibly due to the process of savanization of tropical forests due to climate change. In general, the proportions of forest cover were higher in EA than in EF and INT. The smallest forest cover available in the overlapping areas between current and future distribution indicates that species may have difficulties in dispersing to new areas. Our results demonstrate that climate change will drastically affect habitat suitability and forest cover in future distributions of endemic Atlantic Forest primates.
