Resumen

Climate change is a serious threat to mountain ecosystems and representative species such as birds. Six species of threatened birds present in the Andes of Peru were selected. The objective of the research is to identify potential changes in the spatial distribution of threatened birds in the future (2050). For this, three Global Climate Models (GCM) and a scenario of the Representative Concentration Pathways (RCP) 8.5 were used, and MAXENT was used. The modeling results show significant changes in the size of the occupation area. All species show a high or considerable contraction of the potential area of distribution. The possible changes open the question about the capacity of protected areas (PA) against climate change, giving way to conservation proposals as least cost corridors. It is concluded that the Species Distiibution Models (SDM) are a very useful tool for the spatial responses of the species. The results are a possible approximation of the imminent movement of the species due to the reduction of the potential available habitat. Finally, the importance of concentrating consen-ation efforts based on the mobility of birds due to climate change is emphasized. Copyright:
