Áreas prioritarias de conservación en base al modelamiento de la distribución de tres especies endémicas de la región tumbesina: Ortalis erythroptera, Psittacara erythrogenys y Cyanocorax mystacalis

Abstract

Abstract:Populations of various species are declining rapidly, due to significant conservation difficulties, for example, levels of deforestation and fragmentation of their habitats, expansion of the urban and agricultural frontier, as well as illegal trafficking, particularly in areas of importance to conservation as is the Region of Tumbesina Endemism. The objective of this research was to design distribution models for the species Ortalis erythroptera, Psittacara erythrogenys and Cyanocorax mystacalis as key elements to promote conservation actions in this region. The potential and current distribution of each species is modeled using the Maximum Entropy method, with the Maxent software. The Worldclim climate variables were selected, based on the variables that made the greatest contribution to the model using the Jacknife test. The potential niche area for Cyanocorax mystacalis, 1800 km2 the potential niche area for Ortalis erythroptera, 3000 km2 for Psittacara erythrogenys was determined at 547 km2. The ideal potential distribution area for the three threatened endemic bird species covers a total area of 2,700 km2.
