Development 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 کاملSocial environment and steroid hormones affect species and sex differences in immune function among voles.
Testosterone has bipotential effects on male fitness; that is, it both suppresses immune function and maintains characteristics important for reproductive success. Presumably, these effects of testosterone may be more pronounced among polygynous species because testosterone concentrations are generally higher among polygynous than monogamous males. The present study examined sex and species dif...
متن کاملCART peptide following social novelty in the prairie vole (Microtus ochrogaster).
Prairie voles (Microtus ochrogaster) are monogamous rodents that display high levels of affiliative behaviors, including pair-bonding, biparental care, and cooperative breeding. Species differences in basal cocaine- and amphetamine-regulated transcript (CART) mRNA and peptide expression have been found between prairie voles and polygamous meadow voles. Therefore, we hypothesized that the CART s...
متن کاملInfluence of photoperiod and sex on locomotor behavior of meadow voles (Microtus pennsylvanicus) in an automated light-dark 'anxiety' test.
This study examined the influence of photoperiod on affective behavior (anxiety) of adult male and female meadow voles (Microtus pennsylvanicus), maintained in either a long or short day photoperiod, when tested in an automated (VersaMax) light-dark test. The light-dark test is based on an innate aversion of rodents to novel, brightly illuminated spaces and has been used with laboratory raised ...
متن کاملVariation in oxytocin is related to variation in affiliative behavior in monogamous, pairbonded tamarins.
Oxytocin plays an important role in monogamous pairbonded female voles, but not in polygamous voles. Here we examined a socially monogamous cooperatively breeding primate where both sexes share in parental care and territory defense for within species variation in behavior and female and male oxytocin levels in 14 pairs of cotton-top tamarins (Saguinus oedipus). In order to obtain a stable chro...
