“…At each capture, males were checked for the presence and colour of £uor-escent pigment with a hand-held long-wave ultraviolet light. Because the presence of the female-speci¢c pigment on a male correlates perfectly in all cases with the identity of the genetic father (Ribble 1991), we considered a male that showed the female-speci¢c colour for three or more trapping weeks to have paired with the female. In all cases, such pairs remained together unless the mate died or was experimentally removed.…”

Paternal behaviour presumably evolved because male care of young was critical for o¡spring survival. We report ¢eld evidence indicating that paternal behaviour enhances o¡spring survival in a monogamous mammal, the biparental California mouse, Peromyscus californicus. Male removal resulted in lower o¡spring survival in father-absent than in father-present families. New males took up residence with widowed females, but usually after females had stopped lactating, suggesting that the importance of the father is not primarily protection against infanticidal intruders but rather direct care of young.

“…The two previous genetic studies of monogamous mammals, conducted on Peromyscus polionotus (Foltz 1981) and P. californicus (Ribble 1991), also revealed no EPP. In monogamous Perom scus species, males generally show a substantial amount of parental care (Elwood 1983), and males have been shown to be important for offspring survival in P. californicus (Gubernick et al 1993).…”

SUMMARYLittle is known about the mating behaviour of monogamous mammals. Here, we present behavioural and genetic evidence of fidelity in a socially monogamous dwarf antelope, Kirk's dik-dik. DNA microsatellite analysis revealed no evidence of extra-pair paternity (EPP) in dik-diks : mothers' partners matched the paternal genotype in all 12 juveniles tested. One likely reason for the absence of EPP is that males guard their mates closely during oestrus and over-mark all female scent, thereby reducing the likelihood of other males attempting to mate. In addition, males may be limited in their ability to search for extra-pair copulations (EPCs) by activities associated with pair-bond maintenance. Year-round, males maintained proximity within pairs, followed their females' activity patterns, and spent approximately 64 % of their time with their partners. However, males did attempt to obtain EPCs when the opportunity arose, and genetic monogamy in dik-diks is probably best explained by the behaviour of females : in contrast to many monogamous female birds, female dik-diks do not appear to seek EPC partners. We propose that females avoid extra-pair males because they are unable to mate with them without instigating a potentially dangerous conflict.

“…These symptoms occur without significant obesity or increase in food intake. It may be relevant that P. californicus exhibits among the strictest monogamy of any mammalian species (Ribble, 1991). Monogamy is a rare adaptation with pleiotropic consequences (Clutton-Brock, 1989).…”

SUMMARYElevated glucose levels in the presence of insulin are indicative of type 2 diabetes and the more inclusive metabolic syndrome. Alleles conferring susceptibility to these and other common conditions may be adaptations to past environments. It is possible that other mammals exhibiting environmental diversity harbor similar variants; therefore, we assessed glucose regulation in two species of deer mice (Peromyscus), a diverse endemic North American group. The prairie deer mouse, P. maniculatus bairdii (BW), and the Oldfield mouse, P. polionotus subgriseus (PO) differ in sexual dimorphism, behavior and habitat. PO animals exhibit better regulatory ability than BW animals, particularly among males, although both species display equivalent insulin levels/responses and non-fasted glucose levels. Hybrid males exhibit a PO glucose challenge response and subsequent analysis of consomic animals implicates Y chromosome variation as the genetic cause. Two pieces of evidence indicate that the male glucose regulatory differences are mediated by stress response: (1) fasting and handling alone account for most of the variation; (2) an inhibitor of glucocorticoid (GC) stress hormone synthesis eliminates these differences. PO males have GC levels that are twice those of BW males, indicating the presence of alleles that attenuate the GC response. We hypothesize that the interspecific physiological and behavioral differences are interrelated and that similar human variants exist.
