Resumo
Owing to climate change, species’ geographical distribution may be extended, reduced or displaced in thefuture. Across species’ ranges, novel climate conditions may also expose species to thermal conditionsfor which they are not adapted. Migration toward more suitable climates will, however, only be possibleif species are able to keep pace with climate change. Here, we analyze different metrics to predict theimpacts of climate change on the distribution of Amazon primates. We found that this iconic group willbe exposed to novel climate conditions in a large portion of their territories and most species might notbe able to track their preferred environmental conditions, even when their range is forecasted to expand.Remaining future populations are expected to become fragmented and to occupy sub-optimal conditionsat the periphery of their projected bioclimatic envelopes. Our results suggest that climate change mayhave unprecedented impacts on Amazon biodiversity, especially for species with low dispersal ability, such as primates. In addition to deforestation, hunting, and disease spread, climate change is likely to addup to conservation-defying feedbacks for Amazon primate populations’ fitness and resilience dynamics.
