BISC 445 ENVIRONMENTAL PHYSIOLOGY OF ANIMALS Julian Christians (julian_christians@sfu. ca) Office: SSB 8101 Office hours: Monday, 11: 30 -12: 30 TA: Rodrigo Solis Sosa Email: unitec. solis@gmail. com Office hours by appointment www. sfu. ca/biology/courses/bisc 445/ www. sfu. ca/lectures/

What is environmental physiology? • Physiology is about mechanisms. • Environmental physiology is about physiological responses to environmental challenges. • Environment = physical, chemical and biotic abiotic

What is environmental physiology? Willmer et al. 2005; Fig. 5. 20 Willmer et al. 2005; Fig. 5. 16

Why study environmental physiology? Evolution of Medicine health and disease Physiology Evolution Environmental physiology Toxicology Ecology Response to environmental change

Course outline • • • Four general principles Evolutionary processes Oxygen Temperature Water and ions Deep sea Will NOT focus on humans or mammals

Course objectives I want you to: • Understand four basic physiological principles, and be able to illustrate these with examples, and relate new material to these principles. • Be able to distinguish between evolutionary responses (adaptation) and within-individual responses. • Understand the importance of modern evolutionary approaches to the study of environmental physiology. Proximate causes: How? Ultimate causes: Why?

Course objectives I want you to be aware of: • Mechanisms available for response to environmental challenges (including different responses at different time scales). • General mechanisms frequently involved in a variety of responses. • Some incredible examples of physiological responses to environmental challenges.

Mark distribution • Final exam: 40% • 2 x Midterm exams: 25% each • Tutorial presentation: 10% Exams will be based on tutorial and lecture material.

These Power. Point slides are NOT lecture notes

Tutorials- what’s the point? • To study “primary literature” • To practice critical thinking • To practice presenting scientific material in a clear, jargon-reduced way. • To gain “public speaking” experience in a nonthreatening environment. • To study other examples that illustrate the “ 4 general principles” and other material presented in lecture. Make them interesting! YOU are responsible for rescheduling!
