BIOL 174 Lecture Notes - Lecture 2: Evolutionary Physiology, Comparative Physiology, Ecophysiology
Document Summary
Ladd prosser- founder of comparative physiology and wrote agenda for comparative physiology. 1. ex: how a lizard gets its food. how frogs regulate temp. =cataloging biological diversity, specifically what is the functional diversity: use physiological information to reconstruct phylogenetic relationships of organisms. to make tree of life. Physiological ecology focuses on ecology, and how physiology affects interactions between organisms and their environment. Physiological ecology has always had an evolutionary component. Acclimatization- in the field mouse producing fat in mt. acclimation- in the lab. these changes are reversible. stop working out, lose muscle. Determine how mice adapt ontogenetically to reduced water availability. The effects of early-life water restriction are not completely reversible. , were mostly reversible but not completely. the restricted group gained more mass but never caught up. the one that were just restricted lost mass but were bigger. The kidneys became larger compared to body mass with restricted group. and their urine was a lot more concentrated.
