SUMMARY:

The Atlantic Forest covers approximately 130 million hectares and extends over the entire Brazilian coast. This biome is essential for conserving primates, the mammals with the largest proportion of endangered species. The main threats to these species are habitat loss and climate change. Here, we addressed two questions: (i) what the proportion of forest cover in the current and future expected geographic ranges of Atlantic Forest primate species is? and (ii) are the protected areas efficient in representing areas climatically suitable for primate species in the Atlantic Forest considering current and future climates? To answer the first question, we calculated the forest cover in the region unique of the current species geographic ranges, the intersection region between the current and future geographic ranges, and the region unique of the expected geographical range for species in the future. We compared the current and future climatic suitability for the Atlantic Forest primates within the protected areas to the second question. The current network of protected areas represents higher suitability values compared to species geographic ranges. There was a general reduction in the suitability values in future climate scenarios, which is possibly related to the savanization of tropical forests, and there was no difference between the suitability represented by protected areas and that in the geographic ranges. Regions of intersection between current and future geographic ranges and regions unique to the future showed a higher proportion of forest cover than regions unique to the current geographic range. This result was expected because of the already documented displacement of species from low altitudes areas to high altitudes areas, where there is a bias in the protected areas selection and the location of permanent preservation areas. Our results demonstrate that, although the protected areas are efficient in conserving more suitable areas in the present, there will be a reduction in areas climatically suitable for the Atlantic Forest’s primate species in the future. As a result, these species may need to disperse to more climatically suitable areas. Although most of the geographic ranges foreseen for the future for these species will be composed by matrix, which can make dispersion difficult, the areas of intersection between the current and future geographic ranges presented a greater forest coverage. This can make conservation efforts in these regions more efficient for species both at present and in projections of future climate change. To avoid the loss of these species, joint efforts are necessary to seek the maintenance, expansion, and management of protected areas, reduce the emission of greenhouse gases, incorporation the consequences of the climate crisis on biodiversity in conservation strategies, and guarantee policies public policies that prevent deforestation and restore deforested areas.
