Effects of Environmental Variables on Endocrine States Underlying Some Physiological Responses of Microtus montanus under Natural Conditions
Published 1969-01-01
Abstract
Aims of the Study 1. Determination of the plant estrogen content of the primary food plants of Microtus montanus throughout their breeding season. 2. Investigation of growth, maturation, and reproductive activity of Microtus montanus under natural conditions. 3. Study of maturation molts and seasonal pelage changes in Microtus montanus in relation to sex, age, and reproductive status. 4. A correlation of the information obtained in #1-3 above. It is hoped that the results will help elucidate causes underlying the multiannual population fluctuations of microtine rodents. Project Number 173.
