Document Summary
Biol 208 (january 20, 2014: ectotherms, hs is highly reliant on hcd (conduction), hcv (convection), and hr, endotherms, hs is highly reliant on hm (metabolism, cold temperatures = higher metabolic rate, hot temperatures = higher metabolic rate. This is counterintuitive : sweating and panting take energy to bring down the temperature, most endotherms can deal with higher decreases in temperature increases in temperature, q10. Metabolism goes down for a prolonged period of time. Essentially no activity: estivation is opposite (hibernating at hot temperatures underground, torpor. Lose so much energy that it is hard to maintain energy at night: can"t feed at night so they go through hypothermia for hours until the morning (body temperature drops in that time, death. Is an adaptation in some cases to extreme temperatures: maintenance stopped, and assigned to growth, reproduction, and activity, short lifespan to maximize offspring, migration.
