Leucism occurrence frequency in an island population of tayra (Eira barbara), in Roraima, Brazil: A comparative analysis with camera trap records

Year: 2025

Type: article

Abstract: ABSTRACT Carnivores have a wide variation of color patterns that serve both ecological and physiological functions. However, genetic mutations can lead to the appearance of unusual color patterns, which can directly influence the survival of individuals. Eira barbara is a mustelid usually presenting dark brown fur coloration, but anomalous color variation including leucism has been reported. Here we describe suspected leucism in an island population and compare its frequency of occurrence with previous camera trap studies. We reviewed the scientific literature to identify studies reporting leucism in this species. From an extensive camera trapping effort we report the first cases of suspected leucism in an island population of E. barbara. We discuss these findings in terms of the ecology and conservation of island populations of this species.
