Prerequisite: 15:267, 15:273.

This course will examine the physiological response of animals living in extreme environments. There will be a particular focus on challenging environmental conditions in terms of oxygen, temperature, water and ions, and hydrostatic pressure. The course will use examples drawn from a variety of vertebrates and invertebrates species to illustrate essential concepts and principles in environmental physiology. Every level of biological organization will be considered in the context of their contribution to physiological homeostasis including the biochemical and cellular level, organ systems and whole animal adaptive strategies.

3 lecture hours per week, one term.
