Áreas de endemismo de los anfibios del Paraguay

Abstract

Las áreas de endemismo constituyen la unidad fundamental de la biogeografía histórica, y su identificación es clave para comprender patrones de distribución más generales y brindar información importante para la elaboración de planes de conservación efectivos. En este trabajo identificamos áreas de endemismo para anfibios de Paraguay utilizando información de colecciones científicas y comparamoslos resultados con las Ecorregiones propuestas para el país. La búsqueda de áreas de endemismo se efectuó con el programa NDM/VNDM, bajo diferentes escalas espaciales (grillas de 0.5°x0.5°, 0.7°x0.7° y 1°x1°). Fueron identificadas ocho áreas de endemismos; de ellas siete están en congruencia con las ecorregiones Chaco Seco, Bosque Atlántico, Cerrado, Pastizales de la Mesopotamia, Ñeembucú y Gran Chaco Americano (Chaco Húmedo y Chaco Seco). La octava área identificada no coincidecon ninguna Ecorregión tradicional, pero presenta congruencia con la zona de transición hacia el Chaco Seco entre la Región Oriental y el Chaco Húmedo, indicando posibles procesos de diferenciación de especies en las regiones más húmedas hacia las más secas.
