| 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? (Morphological,
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)?
