1. Time hypothesis
-Communities diversify, or gain species, with time
-Temperate regions have less rich communities than tropical ones because they are younger and have only more recently recovered from glaciation
- Support - more worms in comparable unglaciated lakes than glaciated
- Drawback - limited applicability to marine organisms
A couple of questions for the above "slide"
- What does the support mean for the time hypothesis? I do not understand what that means.
- For the drawbacks - why are marine organisms limited?
