Abstract

Daily energy budgets (DEBs), activity patterns and the energy flow through a population of Peromyscus leucopus (Rafinesque) were studied for one year. The DEB for the nonlactating portion of the population was the highest in winter (0.602 kcal gm-1 day-1) and lowest in summer (0.307 kcal gm-1 day-1). The DEB of lactating females in summer was 24.8 per cent greater than that of males and nonlactating females from the same season. During winter the animals spent 72 per cent of the day in the nest, whereas in summer males and nonlactating females spent only 28 per cent of the day in the nest. Energy flow through the population was maximal in autumn (396.3 kcal ha-1 day-1) when the biomass (715.86 gm ha-1 day-1) was greatest and minimal in spring (170.4 kcal ha-1 day-1) when the biomass (327.54 gm ha-1 day-1) was least. Different intensities of simulated moonlight were found to have no significant effect upon the activity of the white-footed mouse in any season.
