“…Mont er egie is part of the Great Lakes and St. Lawrence River forest system (D'Orangeville et al 2008), which is considered as a transitional zone between the deciduous forests of eastern North America and the boreal forest in northern Canada (Ontario Ministry of Natural Resources 2012). Although both species of mice are found in a variety of habitat types, P. maniculatus favors boreal forests (Garman et al 1994;Myers et al 2005Myers et al , 2009) and shows better adaptation to cold weather than P. leucopus (Pierce and Vogt 1993). This adaptation may explain the relative larger abundance of the deer mouse on Mont Yamaska, which had a greater number of boreal tree species than all other sites, and was the tallest of the four mountains included in this study.…”

The white-footed mouse (Peromyscus leucopus) has expanded its northern limit into southern Quebec over the last few decades. P. leucopus is a great disperser and colonizer and is of particular interest because it is considered a primary reservoir for the spirochete bacterium that causes Lyme disease. There is no current information on the gene flow between mouse populations on the mountains and forest fragments found scattered throughout the Monteregie region in southern Quebec, and whether various landscape barriers have an effect on their dispersal. We conducted a population genetics analysis on eleven P. leucopus populations using eleven microsatellite markers and showed that isolation by distance was weak, yet barriers were effective. The agricultural matrix had the least effect on gene flow, whereas highways and main rivers were effective barriers. The abundance of ticks collected from mice varied within the study area. Both ticks and mice were screened for the presence of the spirochete bacterium Borrelia burgdorferi, and we predicted areas of greater risk for Lyme disease. Merging our results with ongoing Lyme disease surveillance programs will help determine the future threat of this disease in Quebec, and will contribute toward disease prevention and management strategies throughout fragmented landscapes in southern Canada.

“…For example, in the laboratory situation, a rodent may experience little or no forced convection (wind) and a much warmer radiative environment than a rodent aboveground in nature. If mice were underground in their burrow, however, the reduced convection, warmer radiative environment, use of nesting material as insulation, local environmental heating by the mice, and possibility of huddling would make it quite easy for mice to maintain their core body temperatures even when the aboveground thermal environment was quite cold (Vogt and Lynch 1982;Hayes et al 1992;Pierce and Vogt 1993).…”

Adaptive explanations that rely on physiological arguments are common, but tests of hypotheses about the significance of whole-animal physiological performance (e.g., aerobic capacities) are rare. We studied phenotypic selection on the thermogenic capacity (i.e., maximal rate of oxygen consumption [V0 2 max] elicited via cold exposure) of high-altitude (-3800 m) deer mice (Peromyscus maniculatus). A high V0 2 max equates to a high capacity for heat production and should favor survival in the cold environments prevalent at high altitude. Strong directional selection favored high V0 2 max, at least in one year. The selection for increased V0 2 max is consistent with predictions derived from incorporating our physiological data into a biophysical model. During another year, we found weak evidence of selection for decreased body mass. Nonlinear selection was not significant for any of the selection episodes we studied. The strong directional selection for V0 2 max that we observed suggests that-given ample genetic variation-aerobic metabolism and perhaps endothermy may have evolved rapidly on the geological time scale.

“…Rest-phase hypothermia is a second category that is characterized by normal responsiveness to external stimuli and shallower reductions in T b below normothermia (McKechnie and Lovegrove, 2002). Distinguishing between rest-phase hypothermia and torpor in free-ranging animals is usually impossible because it is difficult to obtain behavioural observations (but see Pierce and Vogt, 1993). Therefore, we evaluated the ability of birds to facultatively reduce their T b and use the term torpor to define this state.…”
