Maximum rate of energy assimilation in the bank vole

The maximum cold-induced energy assimilation rate in nonreproducing bank voles Cletrhionomys glareolus (Schreber, 1780) was estimated by means of feeding trails. It reached 2.56 kJXg-1Xday, which is only about 3 times the basal metabolic rate, and approaches the level of the average daily energy budget of this species. This is, however, much less than assimilation rate previously reported for lactating bank voles.
