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

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
PowerPoint
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.
