Modelling 21st-century refugia and the impact of climate change on Amazonia's largest primates

Edaphic and vegetation conditions can render climatically suitable sites inadequate for a species to persist, constraining the amount of suitable habitat and the possibilities of tracking preferred climatic conditions as they shift in response to climate change. We combined climatic and remotely sensed data to model current and future distributions of nine extant taxa of ateline primates across the Amazon basin. We used the models to identify and quantify potential range changes and refugia of suitable habitats from the present to the latter half of the 21st century. We applied an ensemble forecasting approach for species distribution models using 596 spatially rarefied occurrences. We parameterised these models by combining reflectance data from a basin‐wide Landsat TM/ETM+ image composite, three sets of bioclimatic layers containing data for the current period, and two different (moderate and worst-case) climate change scenarios for 2041-2070. Eight out of nine taxa are likely to expe..., , , # Modelling 21st-century refugia and the impact of climate change on Amazonia's largest primates

This repository contains the occurrence data and the R script for multi-species distribution modeling with complete parameter implementation settings. It also includes interactive maps of hotspots of vulnerability to climate change and 21st-century refugia for the nine extant taxa of atelines across the Amazon basin until the mid-21st century (2041-2070). The study was based on an ensemble forecasting approach for species distribution models, combining climatic and remotely sensed data. The dynamic and interactive maps are user-friendly, openly accessible, and designed for ease of use by decision-makers and conservation managers.
