The effect of kinship on spacing among female red-backed voles, Clethrionomys rufocanus bedfordiae.

摘要: I examined the effect of relatedness on spatial organization and reproduction in enclosed populations red-backed voles (Clethrionomys rufocanus bedfordiae) 1984 1985. Enclosures with low high coefficients among females were established, proximity overlap home ranges these recorded before after introduction males. The following conclusion reached: 1. The number that established gave birth to young did not differ significantly enclosures. 2. Before males introduced, sisters had closer than non-sibling females. After some sibling still remained close each other but occupied exclusive near those their sisters. Other groups, particularly 1985, dispersed males' introduction. 3. The or between neighboring decreased introduction, trend was more pronounced for kin non-kin. 4. A female better able acquire an range when a sister neighbor sister. 5. The tendency littermates disperse non-random. difference body weight dispersers residents significant within groups non-siblings introduced at same locations.
