Grand Teton National Park Report
Microtus montanus populations manifest large scale periodic fluctuations in density. Populations of Microtus longicaudus inhabiting the same environment do not exhibit such fluctuations. This study seeks to compare the energetic requirements of the two species at different seasons and among the cohorts that are born successively during the breeding season. From these data we expect to gain a better understanding of the adaptive physiological responses of both species to their environment.
