| Sumario: | Capturing wild animals can be time consuming and difficult or even impractical. Noninvasive sampling is potentially a cost-effective and efficient means to monitor wild animals, thereby avoiding the need of capture and disturb species in the wild. On the basis of the morphological and genetic analyses of owl pellet contents, a so far undetected European snow vole (Chionomys nivalis) population was discovered in the Sierra Segura mountain range (Southern Spain). The mtDNA sequence from the newly discovered haplotype was compared with sequences from vole populations of the Sierra Nevada and Sierra Peñalara mountain ranges (Spain) and from Churwalden (Switzerland). The nine recovered haplotypes clustered in four distinct lineages according to their geographical origin. The vole sequence from the Sierra Segura owl pellet belonged to a new haplotype, constituting a new lineage. The evolutionary divergence between sequences from the Sierra Segura and other Spanish populations was higher than that among other Spanish haplotypes. The new snow vole haplotype from this new locality duplicates the number of occurrence sites of this critically endangered species in Southern Spain, which is of great interest for further conservation and management plans of the European snow vole in the most southwestern area of its entire distribution range. © 2013 Informa UK, Ltd.
