Document Summary
Lecture 2 - temperature 1: principles of thermal biology. Very cold temperatures - use coats, pants, boots, and shelter, etc: other organisms have a harder job, plants are sessile - (cid:272)a(cid:374)"t move and find shelter or shade. Latent heat loss - the transfer of energy through water: condensation and evaporation, breathing - moist air breathing out, sweating - evaporates on the skin, metabolic heat production, creates heat inside the organism, metabolism. Hibernating ground squirrels: regional endothermy/herterothermy: different tb in different parts of the body. Determining what type of animal thermal biology: graph to help in determining what type of thermal biology is used, not always in just one box. Relationship between temperature and metabolism: picture showing the body temp of an ectotherm, as body temperature increases so does metabolic rates, exponential relationship, small changes in temperature leads to large changes in metabolic rates. Metabolic rate equation: note metabolic rate is dependent on body temp, slope = n.
