Resumen

Ecological niche and species distribution models are of great importance, since their results allow for an understanding of many aspects related to the biology of the species under study, even understanding their evolutionary relationships or their response to past or future projections. In this research, climatic surfaces were produced from ground-based meteorological stations in the departments of Arequipa, Moquegua and Tacna. Temperature and precipitation data from 119 stations were obtained and homogenized; then, using geographic and orographic covariates, models were prepared so as to obtain maximum and minimum temperature and precipitation surfaces. The produced surfaces were evaluated by cross validation and compared to other models in the area. Finally, 19 bioclimatic surfaces were created. The results show general patterns for temperature and precipitation, with some particulars. Twelve layers were produced for maximum temperature, minimum temperature and precipitation, respectively, showing acceptable values for RMSEcv and MAD. Comparison with other models shows statistically significant differences. Both the climatic and bioclimatic surfaces produced were placed in a database for free access. Finally, comments are made on the importance and applications of the bioclimatic layers produced here.
