SOCI 1001 Lecture Notes - Lecture 8: Torpor, Photosynthesis, Glycerol
Document Summary
Migration: an annual, two-way journey that is primarily a response to a predictable food shortage, often spends thousands of kilometers. Dormancy: a state of inactivity characterized by reduced metabolic activity and a drop in some or all of body temp, heart rate, respiratory rate lethargy, torpor and hibernation are all types of dormancy. Basking in the sun: used during the early morning sunlight to absorb solar energy for warmth. Torpor: a state of deep sleep animals enter where they reduce their heart rate and body temperature in order to conserve energy. Black capped chickadees drop internal temperature 12 c. By lowering their body temperature, they lose less heat as the difference in temperature between their body and what is around is lowered - the greater gradient. Ectotherms are animals that do not generate their own body heat and can not afford to be out in sub-zero temperatures at all. Frostline is the level at which the frost affects the ground.
