Fine-scale population genetic structure and short-range sex-biased dispersal in a solitary carnivore, Lutra lutra
Popis výsledku v původním jazyce
The genetic structure of animal populations is influenced by, among other factors, dispersal and relatedness. Limited dispersal may cause local spatial restrictions in gene flow, which can have important management and conservation implications. We usedradiotracking and genetic data to verify the existence of a spatial structure in relatedness within a resident native Eurasian otter (Lutra lutra) population at a fine spatio-temporal scale, and to better understand dispersal in this species. We obtained51 individual genotypes from 65 biological samples collected from 2007 to 2010 in an area of southern Portugal of 1,125 km(2). In addition, we radiotracked 7 (2 female, 5 male) young otters. Relatedness estimates and geographic distances were inverselyrelated in females, whereas the relationship was not significant in males. Among the tracked subadult animals, only males dispersed, covering on average a distance of 21 km (SD = 6 km; range: 11-25 km). Both genetic and field data therefo
