Human-induced climate change poses many potential threats to nonhuman primate species, many of which are already threatened by human activities such as deforestation, hunting, and the exotic pet trade. Here, we assessed the exposure and potential vulnerability of all nonhuman primate species to projected future temperature and precipitation changes. We found that overall, nonhuman primates will experience 10 % more warming than the global mean, with some primate species experiencing >1.5 °C for every °C of global warming. Precipitation changes are likely to be quite varied across primate ranges (from >7.5 % increases per °C of global warming to >7.5 % decreases). We also identified individual endangered species with existing vulnerabilities (owing to their small range areas, specialized diet, or restricted habitat use) that are expected to experience the largest climate changes. Finally, we defined hotspots of primate vulnerability to climate changes as areas with many primate species, high concentrations of endangered species, and large expected climate changes. Although all primate species will experience substantial changes from current climatic conditions, our hotspot analysis suggests that species in Central America, the Amazon, and southeastern Brazil, as well as portions of East and Southeast Asia, may be the most vulnerable to the anticipated impacts of global warming. It is essential that impacts of human-induced climate change be a priority for research and conservation planning in primatology, particularly for species that are already threatened by other human pressures. The vulnerable species and regional hotspots that we identify here represent critical priorities for conservation efforts, as existing challenges are expected to become increasingly compounded by the impacts of global warming.

Average (circles) and standard deviation (lines) of temperature and precipitation change for each primate genus. The dotted lines outline the boundaries of the climate change severity categories shown in Table III. Genera are color coded according to the color bar, and those genera expected to experience the largest climate changes (category 4 or higher) are also labeled on the plot. (GIF 187 kb)

Fig. S3Hotspots of primate vulnerability to global warming, calculated as in Fig. 6, but using the number of genera rather than the number of species per km2. Hotspot scores are calculated (per km2) as the product of normalized measures of genera richness, average extinction risk, and climate change severity, and are classified here by quantile. Darkest pixels (upper quantiles) indicate locations of high genera richness, where primates are currently threatened by human pressures, and where large changes in temperature and/or precipitation are expected to occur.
