Self discrimination in meadow voles, Microtus pennsylvanicus.
Particular features of the signaling characteristics of the scent marks of temperate-zone, seasonally breeding mammals may reflect differences in their reproductive state and, hence, be variable. Consequently, an individual's perception of self may depend more on the condition independent than on the condition-dependent signaling characteristics of the scent marks. Yet, we do not know whether a...
متن کاملFemale meadow voles (Microtus pennsylvanicus) demonstrate same-sex partner preferences.
Female meadow voles (Microtus pennsylvanicus) are territorial during warm months but demonstrate social tolerance under low temperatures. In spring, females nest together and some pairs participate in communal nursing and rearing of young. Because communal nursing involves significant cooperation, selective pair-bonds may develop between 2 nestmates. Using a choice apparatus, the authors determ...
متن کاملSexually dimorphic spatial learning in meadow voles Microtus pennsylvanicus and deer mice Peromyscus maniculatus.
A number of studies examining developmental, neural and hormonal aspects of sexually dimorphic spatial learning (Morris water-maze) in meadow voles (Microtus pennsylvanicus) and deer mice (Peromyscus maniculatus) are described. We found that, in adult deer mice, female spatial performance decreased during the breeding season relative to the non-breeding season, whereas the reverse pattern was o...
متن کاملDevelopment of selective partner preferences in captive male and female meadow voles, Microtus pennsylvanicus
Intraspecific social systems vary considerably as a function of environmental parameters (Lott 1984, Behaviour, 88, 266–325). For example, nonmonogamous species may engage in facultative partner preferences and parenting to offset the costs associated with harsher breeding conditions. Because no field or laboratory research has examined nonmonogamous meadow voles under suboptimal conditions (e....
متن کاملChemical triggering of reproduction in Microtus montanus.
In a replicated experiment, nonbreeding winter populations of Microtus montanus were given supplements of rolled oats coated with 6-methoxybenzoxazolinone, a naturally occurring plant derivative. After 3 weeks of this feeding regime, samples from the populations demonstrated a high incidence of pregnancy in females and testicular hypertrophy in males. Control populations receiving rolled oats c...
