Kin Recognition and Social Behavior in Microtine Rodentshanism that underlies kin recognition for vole species that have been examined. Yet association during preweaning may not be adequate for all species at certain times of year. Some vole species form communal groups during the breeding season, whereas other species nest communally during the nonbreed

Social Organizational Modes in Models of Microtine Cyclingles. Unclear or typological concepts of social organization and inadequate data on year — round social structure are barriers to this understanding. The social organizational mode is defined as a subunit of social organization within a species, such as the exclusive territories of breeding female me

Microtine Social Systems, Adaptation, and the Comparative Methodsumed that species can be assigned accurately to a single social system. We assert that, due to phenotypic plasticity of individuals and interpopulational variation, such typological thinking often is not justified. The main implication of phenotypic plasticity is that it undermines current applicat

During the nonbreeding period, home ranges overlapped greatly among both males and females, especially at high densities, and the level of intraspecific aggression was low. Int

Sixty percent of subadult males captured were implanted either with testosterone capsules to increase their aggressiveness (treatment enclosure) or with oil capsule shams (control enclosure).
