AbstractPast responses to environmental change provide vital baseline data for estimating the potential resilience of extant taxa under future climate scenarios. Here, we investigate the latitudinal range contraction that terrestrial and freshwater turtles (Testudinata) experienced during the Late Cretaceous to Paleogene interval (100.5?23.03 million years ago) in response to major climatic changes, encompassing the extremes of global greenhouse and icehouse conditions. We apply ecological niche modelling (ENM) to reconstruct turtle niches, using ancient and modern distribution data, palaeogeographic reconstructions, and the HadCM3L climate model to quantify their range shifts in the Cretaceous and late Eocene. We then use the insights provided by these models to infer their probable ecological responses to future climate scenarios (RCP 4.5 and 8.5 for 2100), which invoke globally increased temperatures and spreading arid biomes at lower to mid-latitudes. Turtle ranges are predicted to expand poleward in the Northern Hemisphere, with decreased habitat suitability at lower latitudes, inverting a latitudinal range contraction trend experienced since the Eocene. Trionychids and freshwater turtles can more easily track their niches than Testudinidae and other terrestrial groups, but stronger anthropogenic pressure at higher latitude will probably reduce their capability to cope with future climate changes.
