Resumen:
Abstract Ectothermic organisms strongly depend ontemperature, making them an excellent model to study theimpact of global climatic change (GCC). Under globalwarming, species may be forced to move toward colderenvironments, such as higher latitudes, higher elevations orboth. However, several studies show that responses mayvary significantly in different groups of species. Therefore,it is unclear whether species? current distribution rangesizes will be affected in future climatic scenarios. Inaddition to the specific possible effect of range size changes,the potential consequences of distributional rangeshifts also should be considered. Here, our aim is to assesswhether GCC may affect a group of Liolaemus lizardspecies based on their current geographic distribution rangesize and whether the effect is uniform across all speciesusing species distribution models (SDMs). Our resultsshow that range boundaries of the fourteen species switchtoward higher altitude and latitude in future scenarios.Additionally, there is not a unique pattern in terms ofincrease or decrease in potential range for lizards in Patagoniain future scenarios. Finally, our results show that theoriginal distribution range size is determinant for theresultant SDMs projections, suggesting that species with ahigh degree of endemicity may be susceptible to a greaterimpact of GCC.
