Metabolism And Adverse Conditions Flashcards
What do many environments do
Vary beyond tolerable limits for normal metabolic activity for any particular organism. Some animals adapt to adverse conditions while others avoid.
What happens during dormancy
Decrease in metabolic rate, heart rate, breathing rate and body temperature.
What is dormancy a part of
Part of an organisms lifecycle is to allow survival during a period when the costs of continued normal metabolic activity are too high.
What happens to metabolic rate during dormancy
Metabolic rate can be reduced during dormancy to save energy.
What can dormancy be
Predictive or consequential
Predictive dormancy occurs….
Occurs before the onset of adverse conditions.
Consequential dormancy occurs….
After the onset of adverse conditions
What does aestivation allow
Allows survival in periods of high temperature or drought
What is daily torpor
Is a period of reduced activity in some animals with high metabolic rates
What does migration avoid
Migration avoids metabolic adversity by expending energy to relocate to a more suitable environment
What can migratory behaviour be
Can be innate and learned
What are specialised techniques used to study
Used to study long distance migration
Examples of specialist techniques
Satellite tracking
Leg rings
What is hibernation
Some mammals survive during winter by hibernating
