C. Animal temperature regulation

1. Poikilotherms

2. Homeotherms

3. Relative cost of P & H?

4. Physical adaptations of organisms

facilitating homeostasis?

(Hint: changes over latitudes)

5. Special nature of aquatic environments

a. Major heat sink for homeotherms

(countercurrent exchange)

b. Relatively constant for poikilotherms

6. Responses to extreme temperatures

(plants & animals)

-Know the strategies to deal with this

(e.g. torpor, hibernation, estivation)
