Locomotor, climbing, and nesting behaviors of wild-caught and captive-born deer mice (Peromyscus maniculatus Wagner) from mainland Nova Scotia and from an isolated predator- and competitor-free island were compared in a laboratory observation room. Locomotor activity did not differ consistently between populations, but wall-seeking was significantly greater in mainland mice. When exposed to an artificial tree, insular mice made more climbs than mainland mice, but mainland mice climbed for longer periods. Climbing behavior differed little between males and females in any group. In a choice experiment, mainland mice selected elevated nest sites significantly more often than ground-level nest sites, while insular mice exhibited no preference.

Nest-sites of female Peromyscus maniculatus borealis were monitored during 1985 and 1986 in the Kananaskis Valley, Alberta, Canada. Nest-site relocation by breeding overwintered adults and young of the year was common. There was no significant difference in the distance moved between years and sites or among reproductive-status groups. Nest relocations were most common in 1985, when population density was approximately half that in 1986. There were no differences in the numbers of relocations per season due to site or age. Females in breeding condition moved 3 times more frequently than did nonbreeders, which were young of the year. Relocations were most frequent at parturition and during early lactation, and thus may serve as a predator-avoidance mechanism. Some relocations by females may have served to leave former nest sites to offspring from previous litters.

Female deer mice (Peromyscus maniculatus) near Vancouver, British Columbia, were found to have a bimodal pattern of breeding. This paper compares the success of females that attempted to breed in the early peak of breeding with that of females that did not breed until the later breeding peak. While the average success was about the same for the two tactics, early breeding had a much higher variance. It is suggested that this difference in variances would result in eventual elimination of the early-breeding phenotype, unless it were favored by other factors. Differences in the selection pressures on males and females, and the relatively frequent occurrence of years of good reproductive success for early-breeding females, may contribute to the maintenance of this phenotype in the population. A hypothesis is presented to explain both the bimodality of the breeding pattern, and the dominance of the second breeding peak.

This study was designed to investigate the abundance and related demographic attributes of Peromyscus maniculatus and Microtus oregoni populations in successional burned and unburned cutover areas. These populations were livetrapped in three habitats at Maple Ridge, British Columbia, from March to October 1978. The average densities of deer mice and Oregon voles per hectare on the burned area were 27.6 and 11.6, and on two unburned areas were 19.1 and 16.0, and 21.9 and 10.4, respectively. There was little variation in the proportion of breeding animals among habitats for either species. Male deer mice survived better on the burned area than in either of the other two habitats; there was little variation in survival among females. Males and females of M. oregoni survived equally well. Deer mice generally had greater proportions of reproductive animals and survived better than Oregon voles on all study areas. However, juvenile voles had 1.7 times higher survival than young deer mice. Demographic parameters within populations of P. maniculatus and M. oregoni tend to be similar in successional burned and unburned habitats 4–5 years after logging.

Capture success for deer mice (Peromyscus maniculatus) in 18 499 trap nights (TN) at 16 localities in northern Nova Scotia between 1977 and 1982 indicates an unusual and prolonged decline in abundance of that species in habitats it normally occupies. The decline has been most extreme on hardwood slopes in the Cape Breton Highlands. The population on Isle Haute, an isolated island in the upper Bay of Fundy, has shown no decline during the sampling period.

Κ Receptor

Background: Novel short-acting κ(kappa)-opioid receptor selective antagonists are translational tools to examine the impact of the κ-receptor/dynorphin system in assays related to central nervous system dysfunction (e.g., substance use disorders, anhedonia and depression). The effects of such compounds have been compared in males and females under very limited conditions. Aims: The goal of this study was to examine potential sex differences in the effects of a κ-agonist and a short-acting κ-antagonist in an ethologically relevant test of anhedonia, the “splash test” of self-grooming, and also in the forced swim test and in locomotor activity. Methods: We examined the dose-dependence of grooming deficits caused by the κ-agonist U50,488 (0.1–3.2 mg/kg intraperitoneal (i.p.)) in gonadally intact adult male and female C57BL/6J mice. We then compared the effects of the short-acting κ-antagonist LY2795050 ((3-chloro-4-(4-(((2S)-2-pyridin-3-ylpyrrolidin-1-yl)methyl) phenoxy)benzamide)); 0.032–0.1 mg/kg i.p.) in blocking grooming deficits caused by U50,488 (3.2 mg/kg). The effects of LY2795050 were also studied in the forced swim test (FST). The effects of LY2795050 in blocking the locomotor depressant effects of U50,488 (10 mg/kg) were also studied. Results: U50,488 produced dose-dependent grooming deficits in male and female mice, and LY2795050 prevented these effects. In contrast, LY2795050 decreased immobility in the FST in males at a dose of 0.1 mg/kg, but not in females, up to a dose of 0.32 mg/kg. Also, LY2795050 (0.32 mg/kg) prevented and also reversed the locomotor-depressant effects of U50,488 (10 mg/kg), in males and females. Conclusions: This study further implicates the κ-receptor system in ethologically relevant aspects of anhedonia, and confirms sexual dimorphism in some behavioral effects of novel κ-antagonists.
