Abstract

We conducted a study to test the hypothesis that there is no difference in the frequency with which southern short-tailed shrews, Blarina carolinensis, use mole tunnels during cold weather vs. during warm weather. Snap-trapping was conducted for eighteen consecutive nights at each of eight different grids, four during winter and four during late spring. The proportion of aboveground captures during winter trapping was significantly less than during spring trapping, indicating that individuals of B. carolinensis use mole tunnels more frequently during cold weather. However, during both winter and spring, significantly more captures of shrews occurred in mole tunnels than aboveground. During both winter and spring sampling, subterranean temperatures varied less than those at the soil surface. Mean body weight of males captured during winter was significantly greater than that of males captured during spring and of females captured during both winter and spring.
