| Popis: | Pine voles are assumed to be cooperative breeders that live in extended families. We applied DNA fingerprinting techniques using restriction enzyme Alu I and Jeffrey's probe 33.15 to wild-caught pine voles to estimate relatedness among individuals in social groups. Background band-sharing between unrelated individuals revealed a high degree of genetic variation ( X BS ± SD = 0.28 ± 0.09). Band-sharing values that range from 0.47 ± 0.20 to 0.60 ± 0.12 from putative groups suggest that groups form from simple nuclear families that may contain some unrelated individuals. In two of the five groups, band-sharing values suggest that offspring from previous litters remain philopatric beyond weaning, while parents produce successive litters. Furthermore, within-group band-sharing values are consistent with a monogamous mating system. This study provides preliminary genetic evidence concerning the degree of relatedness among individuals within groups of pine voles in an orchard habitat. |
