Seasonal Moulting in Deer Mice (Peromyscus maniculatus) in the Rocky Mountains, Alberta

Crisia A. Tabacaru, John S. Millar, Frederick J. Longstaffe

Abstract


We recorded seasonal moulting in North American Deer Mice (Peromyscus maniculatus) in the Kananaskis River valley, Alberta, Canada, to test the hypothesis that moulting is restricted to the times of year that do not overlap with other high-energy demands, such as reproduction (spring and summer), or with low nutrient availability (winter). Although a seasonal trend showing a peak in moulting in the post-breeding period provided support for our prediction, a low level of continuous moulting did occur throughout the year.
