Migration 3/thermoregulagion 1 Flashcards
What is V formation flight in migrating birds?
Birds behind the leading bird pick up lift, which costs them less to flap their wings
What is hypometabolic?
They reduce their metabolic rate prior to migration
What is the thermal neutral range?
The temperature range in which the animal doesn’t need to metabolically thermoregulate
What is endothermy?
Generation and regulation of body temperature
What is homeothermy?
Thermoregulation that maintains a stable internal body temperature regardless of external influence
What is ectothermy?
Regulation of body temperature through the external environment
What is poikilothermy?
Internal temperature varies considerably due to the environment
What are the three factors affecting heat transfer?
Surface area
Temperature difference
Specific heat of conductance
How can ectotherms regulate body temperature?
Morphology
Behaviour
Physiology
