Leucismo en la musaraña de orejas cortas Cryptotis mexicana (Mammalia: Soricomorpha), endémica de México Leucism in Mexican small-eared shrew Cryptotis mexicana (Mammalia: Soricomorpha), endemic to Mexico

Abstract

El leucismo es la reducción de la pigmentación parcial o total del pelaje, pero que mantiene la coloración normal de los ojos y la piel. Aquí se presenta el registro de un individuo de la musaraña endémica de México Cryptotis mexicana recolectado en Veracruz, México, que presenta esta condición. Esta coloración, considerada anormal en estado silvestre, puede incrementar la presión de selección sobre esos individuos. Además, es un reflejo indirecto de la baja variabilidad genética en las poblaciones naturales.Leucism is the partial or complete reduction of the fur pigmentation where eyes and skin maintain their normal coloration. In this paper, we report the record of an individual of the endemic Mexican shrew Cryptotis mexicana from Veracruz, México, that displays leucism. This lack of pigmentation, uncommon in the wild, may result in negative selective pressure on these mammals. Moreover, this genetic-based condition reflects on the low levels of genetic variability within natural populations.
