Abstract:

A live trapping study of Akodon azarae was conducted in a roadside of Pampean agroecosystem to examine the effect of food and cover availability on space use and territoriality in this species. During the breeding season, females presented a strong territorial behavior which was lost during the non-breeding season. No territorial behavior was observed in males in either season. In females, but not in males, home range election and size was negatively associated with food and cover availability. During the breeding season males home range doubled that of females and mating formation was not detected. Finally, for A. azarae individuals at roadsides we propose a promiscuous mating system. We believe that the responsiveness of females to resources quality reflects a direct reliance on resource acquisition for reproductive success. In contrast, the lack of responsiveness of males to resource may reflect a relative independance from resource acquisition in seeking reproductive success. © 1992, Walter de Gruyter.
