Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker

Adult meadow voles (Microtus pennsylvanicus) are solitary in the spring–summer reproductive season, but during winter months, females and males are socially tolerant and aggregate in groups. This behavioral difference is triggered by day length: female meadow voles housed in short, winterlike day lengths form same-sex partner preferences, whereas those housed in long, summer-like day lengths are less social. The present study demonstrates that same-sex social attachments in short day lengths are not exclusive; females formed concurrent attachments with more than one individual, and with non-kin as well as siblings. Partner preferences between females were established within one day of cohousing …
Maternal Photoperiodic History Affects Offspring Development In Syrian Hamsters, Annaliese K. Beery, Matthew J. Paul, Irving Zucker
Maternal Photoperiodic History Affects Offspring Development In Syrian Hamsters, Annaliese K. Beery, Matthew J. Paul, Irving Zucker

During the first 7 weeks of postnatal life, short day lengths inhibit the onset of puberty in many photoperiodic rodents, but not in Syrian hamsters. In this species, timing of puberty and fecundity are independent of the early postnatal photoperiod. Gestational day length affects postnatal reproductive development in several rodents; its role in Syrian hamsters has not been assessed. We tested the hypothesis that cumulative effects of pre- and postnatal short day lengths would restrain gonadal development in male Syrian hamsters. Males with prenatal short day exposure were generated by dams transferred to short day lengths 6 weeks, 3 weeks, …
Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker
Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker
Neuroscience: Faculty Publications
Non-sexual social bonding between adult mammals remains poorly understood, despite its importance in many species. Female meadow voles are territorial and nest alone in long summer day lengths when circulating estradiol concentrations are high, but cohabit in groups in short winter photoperiods when estradiol secretion is low. The influence of day length and estradiol on same-sex huddling behavior was assessed in adult female pairs housed together in long day lengths (LDs) or short day lengths (SDs) from weaning. The behavior of intact, ovariectomized, and estradiol-treated ovariectomized females from each photoperiod was assessed during 3 hour partner preference tests. Intact SD …
