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?
