| Lesson
points |
- What is the key critical thing that must
not happen
for insects under cold conditions?
- How is that different from the key
threat for
mammals and birds (as homeotherms)
under cold conditions?
- If both insects and plants are generally
at ambient
temperatures - what additional concerns are
there for insects in
regards to intercellular freezing?
- What are the 2 general strategies that
insects have
for dealing with freezing temperatures?
- What
are key adaptations for each strategy?
(Morpholgical, physiological,
behavioral)
- How
is it that some of these adaptations are
shared by these 2 strategies
even thought the strategies are opposite
(incompatible) in their goals?
- Under
what environmental conditions might each
strategy be found (explain
why)?
