Temp relations Flashcards
Microclimate
Really local weather, climate variations across a few km, m, cm
What influences microclimates
altitude
aspect- temperatre differnce created by shading
vegetation
ground color
boulders and burrows
terrestial vs aquatic
Thermoregulation
May organisms have mechanism/behiviors that compensate for variation in environmental temp and allows then to maintain internal remoereatrure within a toolerable range
Endotherms
Bodies warmed by heat generated bu metabolis, high energy strategy permits instance activity (most mammals?)
Hemeothermms
Try to body keep temperature constant (animals that function at best at a specific temp)
Poikliotherms
Allows body temperature to fluctuate (animals that function no matter the temp)
Ectotherm
Body temps rely on heat from envirment. Do not produce enough metabolic heat, less energy required, less active (cold blooded?)
Convection
Transfer of heat movement of air or liquid past surface (constant replacement of air/liquid increases rate of conduction)
Radiation
Transfer of heat between 2 bodies that don’t touch
Evaporation
removal of heat from surface as a liquid is loosing molecules as gas
Conduction
direct transfer of heat between 2 bodies in direct contact (water conducts more than air)
Thermal neutral zone
Range of temperature. Ofer which the metabolic rate of a homeothermic animal does not change
