Seasonal surface activity patterns of captive and free-ranging skunks at Delta Marsh, Manitoba, Canada, were determined using radio telemetry and visual observations. Activity decreased sharply between September and mid-December, and was virtually ni

Seasonal changes in the microenvironment of Ondatra zibethicus in Delta Marsh, Manitoba, Canada, are described. In winter, well-insulated, closely-spaced resting and feeding shelters provided an equable microclimate moderated by the presence of open

1. 1.|Thamnophis siralis parietalis maintains normal activity from 30°C to about 18°C, but seeks shelter and becomes inactive below 17°C. 2. 2.|Appetite, as reflected by food intake, is maximal and fairly stable between 30° and 20°C, but is mark

Short-term cold exposure (7°C) of warm acclimated (24°C) laboratory rats had no effect on in vivo synthesis of deoxyribonucleic acid (DNA) (as reflected by incorporation of intraperitoneally injected tritiated thymidine [3H-thymidine] into DNA) in

Exposure of Thamnophis sirtalis parietalis to elevated temperatures immediately after emergence from hibernation induced intense mating behavior. The thermal threshold for courtship varied widely among individuals, and ranged from below 5 °C to betw

Seasonal variation in food of the beaver (Caster canadensis Kuhl) was examined on the Mackenzie Delta, Northwest Territories, Canada. Leaves and, to a lesser extent, growing tips of willow (Salix spp.) were the main food items during July and August;
