Document Summary
In an ectotherm, as tb increases the rate of oxygen consumption also increases: metabolic rate: If you increase light intensity: needed = imbalance) If our body heat is higher than ta, we"re going to lose heat by dry heat transfer in passive way (doesn"t cost metabolically: dry heat transfer involves convection, conduction, and radiation (no moisture) In brown fat individuals, they have another protein where instead of producing. Insects are the most successful group of terrestrial animals. If you don"t start ice crystallization, you won"t freeze. Increased precipitation more rain: winters are changing, temperature is getting warmer, snow melting = no buffer, overwintering under the snow cover is a buffer because the temperature is the same but above snow cover, it varies more. If throughout the winter, temperature crosses the threshold several times the insect will freeze and thaw = damaging. Inducible proton leak thermogenesis: ros = byproduct of aerobic respiration, mitochondrial incompatibilities lead to metabolic dysfunction.
