Genetic relatedness affects socio-spatial organization in a solitary carnivore, the European pine marten

摘要: Genetic relatedness among individuals can play a major role in the socio-spatial organization of mammals. However, only few studies have documented kin-related spatial pattern solitary medium-sized carnivores. Using radiotelemetry and genetic data from 15 (seven males eight females), we investigated relationship between kinship (distance overlap home ranges) European pine marten Martes martes wooded area central Italy. Data analysis included 45 pairs (10 individuals) tracked spring summer 66 (12 autumn winter. Kinship, distance ranges proportion range were also compared inter- intra-sexual pairs. Spatial distribution martens was affected by relatedness, so that living close proximity or occupying same more likely to be closely related. Female had higher their core than male Male less related female inter-sexual pairs, showing space use consistent with male-biased dispersal philopatry. Most females overlapped genetically related, while third territories kin. our results seem indicate positive association mainly consequence common philopatry rather kin-biased tolerance. Male-female dyads highest percentage overlapping ranges, suggesting segregation is unlikely preventing encounters
