2.5: Metabolisim and Adverse Conditions Flashcards
Describe the purpose of dormancy
to survive adverse conditions when the cost of normal metabolic activity would be too high
What occurs during dormancy
a decrease in metabolic rate, heart rate, breathing rate and temperature
What’s the difference between predictive and consequential dormancy
predictive dormancy is when dormancy occurs before the start of adverse conditions
consequential is when dormancy occurs after adverse conditions occurs
GIve 3 examples of dormancy
Hibernation
Daily Torpor
Aestivation
Describe hibernation
the survival or low temperatures
Describe Aestivation
the survival or high temperatures or drought
Describe Daily torpor
a period of reduced activity in animals with a high metabolic rate
Why would some animals migrate
to avoid adverse conditions
define migration
expending energy to move to a warmer climate to avoid adverse conditions
Disadvantage of migration
lots of energy is expended
What technique is used to study long term migration
Satellite tracking
Leg tags
State the influences on migratory behaviour
migration can be innate (born with) or learnt
Why is metabolic rate reduced during dormancy
to save energy
