Migration 2 Flashcards
How can metabolic rate be measured during flight?
Using wind tunnels and measuring oxygen consumption
Why does flight generate a lot of heat?
Because of the large flight muscles that are used
Where is heat usually dissipated in the bird?
The legs
Does the birds core body temperature increase during flight as ambient temperature increases?
Yes
At what temperature is there an increasing rate at which the starling loses water?
10 degrees
Which fuel is used during exercise in mammals?
As exercise intensity increases fat oxidation decreases and carbohydrate oxidation increases
Which fuel is used during exercise in birds?
The reliance on fat oxidation increases as exercise intensity increases in birds
What is phenotypic plasticity?
When different environments can directly induce changes in an individuals behaviour, morphology and physiology
Give an example of phenotypic plasticity
Organ changes
