Nearly every habitat on earth, from thermal hot springs to polar ice caps, is home to some form of life. Physiological Ecology explores the biotic and abiotic challenges to organisms imposed by their environments and adaptations which allow them tosurvive in various habitats, both in terms of how organisms physiologically adapt to short-term fluctuations in their environment and how adaptations influence biogeographic distribution and evolutionary success of various species. Topics include adaptations related to temperature, water and salt balance, and gas exchange. Adaptations of organisms to extreme or unusual environments may be considered. Prerequisite: BIOL 202, 203, 451 or instructor's permission. Spring, alternate years.|
