2.5 Metabolism & Adverse Conditions Flashcards
1
Q
many environments can vary beyond…
A
the tolerable limits for normal metabolic activity
2
Q
To survive harsh conditions, animals have to either…
A
adapt or avoid
3
Q
dormancy and what it allows
A
- dormancy is the reduction of metabolic rate to save energy
- allows survival when the costs of continued normal metabolic activity would be too high
4
Q
what is decreased in dormancy (4)
A
- metabolic rate
- heart rate
- breathing rate
- body temperature
5
Q
types of dormancy (2)
A
- predictive
- consequential
6
Q
when does predictive dormancy begin?
A
before the onset of adverse conditions
7
Q
when does consequential dormancy begin?
A
after the onset of adverse conditions
8
Q
hibernation (2)
A
- used to survive winter or periods of low temperatures
- often predictive, so animals consume extra food to build up fat
9
Q
aestivation
A
allows survival in periods of high temperatures a drought
10
Q
daily torpor
A
a period of reduced metabolic activity in some animals with high metabolic rates
11
Q
migration
A
avoids metabolic adversity by expending energy to relocate to a more suitable environment
12
Q
migration can be…
A
innate or learned
13
Q
long distance migration can be studied by using (2)
A
- satellite tracking
- leg rings
