Ecophysiology is a relatively recent interdisciplinary field, and although active prior to the 75th anniversary of the American Society of Mammalogists (ASM), it has grown in breadth since then. This growth is in part a result of advances in technolo

Understanding physiological limits and environmental optima is critical to developing protection strategies for endangered and threatened species. One theory to explain the decline in endangered Indiana bat Myotis sodalis populations involves increas

Eastern red bats (Lasiurus borealis) will move into leaf litter during cold bouts of winter, and because temperatures fluctuate at these roosts, our 1st goal was to quantify winter arousals in response to ambient temperature (Ta). Additionally, we me

It has been shown in some species that fetal testes produce testosterone early in gestation. This study investigated the possibility that fetal testosterone may be reflected in maternal serum levels in the Asian elephant (Elephas maximus). Weekly ser

Energy budgets have proven to be a valuable tool for predicting life history from physiological data in terrestrial vertebrates, yet these concepts have not been applied to the physiological effects of contaminants. Contaminants might affect energy b

Among the myriad of recent studies on endocrine-disrupting chemicals, relatively few involve thyroid disruption, and most of these address exposure/disruption during embryonic life. Of those involving adult vertebrates, the endpoints examined are thy

Concentrations of serum progesterone and prolactin were assessed during the perioestrous period and throughout gestation in the Asian elephant (Elephas maximus) as a means of generating information of potential use to managers. In >95% of perioestrou

Previous studies on thyroid hormones in hibernating bears have used very few sampling periods, so that the time course of any change is poorly understood. In this study, plasma sampled from pregnant and nonpregnant black bears before and during hiber

This study investigates the environmental cue(s) used by cotton rats to mediate seasonal shifts in thyroid function and metabolism. Summer-caught and winter-caught animals were exposed to combinations of five photoperiods and two temperatures for 60
