Metabolism and adverse conditions - learning outcomes/questions Flashcards
Many environments vary beyond what for normal what for any particular organism?
Many environments vary beyond the tolerable limits for normal metabolic activity for any particular organism
Some animals have done what to survive these adverse conditions while others do what?
Some animals have adapted to survive these adverse conditions while others avoid them.
During dormancy there is a decrease in what?
During dormancy there is a decrease in metabolic rate, heart rate, breathing rate and body temperature.
Dormancy is part of some organisms’ life cycle to allow to do what?
Dormancy is part of some organisms’ life cycle to allow survival during a period when the costs of continued normal metabolic activity would be too high.
Why can metabolic rate can be reduced during dormancy?
The metabolic rate can be reduced during dormancy to save energy.
Dormancy can be what?
Dormancy can be predictive or consequential.
Definition of predictive Dormancy?
Predictive dormancy occurs before the onset of adverse conditions.
Definition of consequential Dormancy?
Consequential dormancy occurs after the onset of adverse conditions.
Some mammals survive during winter/low temperatures by what?
Some mammals survive during winter/low temperatures by hibernating.
Aestivation allows survival in periods of what?
Aestivation allows survival in periods of high temperature or drought.
Daily torpor is a period of what?
Daily torpor is a period of reduced activity in some animals with high metabolic rates
Migration avoids what by expending energy to relocate to a more suitable environment?
Migration avoids metabolic adversity by expending energy to relocate to a more suitable environment.
Migratory behaviour can be what?
Migratory behaviour can be innate and learned.
Specialised techniques are used to study what?
Specialised techniques are used to study long-distance migration.
Examples of specialist techniques are what?
satellite tracking
leg rings.
