Therefore, our goal was to report leucism for Akodon affinis, an endemic species from Colombia, and to analyze the pattern of leucism prevalence in different populations. A. affinis specimens deposited in the Mammals Collection of Universidad del Valle (UV) were examined, and any traces of leucism and its prevalence were recorded for 12 different localities where this species was found. These localities were sampled in different years. The association between incidence of leucism and sex was assessed using a Two-tailed Fisher's exact test. A total of 11 individuals from five localities displayed traces of leucism in different parts of their body (Table 1, Appendix 1), including cheeks, dorsum and venter (Figure 1). The analysis revealed that the incidence of leucism was higher in males vs. females. Traces of leucism were most frequent in the dorsum than any other part of their body. Although this species is considered as a Least Concern by the International Union for Conservation of Nature (IUCN), these findings suggest that populations of A. affinis might be experiencing inbreeding; however, more information is needed to establish the reproductive and survival consequences of this condition on A. affinis populations.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[El leucismo es una condición donde los animales presentan una pérdida de pigmentos en ciertas partes de su piel, sin afectar tejido blando, condición que ha sido pobremente reportada para roedores neotropicales. Por lo tanto, nuestro objetivo fue reportar leucismo en Akodon affinis, una especie endémica de Colombia, y analizar su patrón de prevalencia en diferentes poblaciones. Una revisión de los individuos de A. affinis depositados en la Colección de Mamíferos de la Universidad del Valle (UV) fue llevada a cabo, donde se registró información de leucismo y su prevalencia para 12 localidades diferentes donde esta especie fue encontrada. Estas localidades fueron muestreadas en diferentes años. La asociación entre la incidencia de leucismo y el sexo se evaluó con una prueba exacta de Fisher a dos colas. Un total de 11 individuos de cinco localidades diferentes fueron encontrados con rastros de leucismo en diferentes partes de su cuerpo (Tabla 1, Apéndice 1), incluyendo sus mejillas, dorso y vientre (Figura1). Los resultados indican que la incidencia de leucismo fue mayor en machos que en hembras. Por otro lado, los rastros de leucismo fueron más frecuentes en el dorso en comparación a las otras partes del cuerpo. Aunque esta especie es considerada como Preocupación Menor por la Unión Internacional para la Conservación de la Naturaleza (UICN), estos hallazgos sugieren que las poblaciones de A. affinis pueden estar sufriendo de endogamia; sin embargo, es necesaria más información para establecer las consecuencias de esta condición sobre la reproducción y supervivencia de las poblaciones de A. affinis.]]></p></abstract>
