Uso de pelos de guardia para la identificación de mustélidos costeros en la Patagonia

The use of prey hairs found in predator faeces with the purpose of species recognition has been successfully utilized. In this study, a method was developed to discriminate between hairs from aquatic mustelids of Patagonia: the native otters Lontra provocax and L. felina, and the introduced mink Neo...

In this study, a method was developed to discriminate between hairs from aquatic mustelids of Patagonia: the native otters Lontra provocax and L. felina, and the introduced mink Neovison vison. We found that the relationship between the width of the medulla and the total width (medulla+scales) in the zone of maximum width of the hair, allows effectively separating Lontra spp. from Neovison sp. in almost all samples. With these results, we developed a dichotomic guide that allows discriminating 100% of hair at the level of genera, and 58.3% of hair at the level of species within Lontra.info:eu-repo/semantics/openAccessUniversidad de Valparaíso.
