Territoriality and its consequences

Bujalska G., Saitoh T.

Polish Journal of Ecology

2000

Vol. 48, Suppl.

37-49

A survey of the literature on territoriality of mature female bank voles is presented, with particular reference to the idea of breeding territority and female behavior aimed at the territory defense. Territory (breeding area) is part of home range (foraging area), and its biological meaning is disputable: either it provides food resources for the young or progeny safety. Breeding territories of males are also discussed. Genetic analyses showing kin groups of females and their reproductive succes are important for our understanding of evolution of female territoriality. Attention was also paid to spacing behavior of territorial males and females and the resulting mating system that allows for cases of multiple paternity. Another disputable aspect of female territoriality is its possible importance for stamility of breeding rate and, as consequence, for decrease in variation of population numbers.
