Surviving Adverse Conditions Flashcards
(10 cards)
explain the importance of surviving or avoiding adverse conditions
Many environments vary beyond the tolerable limits for the normal metabolic activity of an organism. Some animals have adapted to survive these adverse conditions while others avoid them
name five types of dormancy
predictive, consequential, hibernation, aestivation, daily torpor
define predictive dormancy
an organism becomes dormant before the arrival of adverse conditions (usually genetically programmed)
define consequential dormancy
an organism becomes dormant after the arrival of adverse conditions (occurs in unpredictable conditions)
define hibernation
a form of dormancy which allows mammals to survive. adverse winter conditions before hibernation, a mammal eats extra food to store as fat. during hibernation metabolic rate is decreased
Define aestivation
A form of dormancy which allows organisms to survive high temp and drought in summer
Define migration
A method of avoiding adverse conditions by expending energy to relocate to a more suitable environment
Describe ways of tracking migration
Individual marking= marking organisms and attempting recapture. Transmitters= attached to animals bodies
Describe innate influences
Inherited behaviour. Inflexible
Describe learned influences
Gained through experience. Begins after birth
