Lecture 10

Question 1

What is dispersal, why is it done, and what are some examples?

Question 2

What are metapopulations and why does it stop extinction?

Question 3

Explain metapopulation dynamics: why is it when a population is isolated it goes extinct but when it is part of a meta population it can live longer (dispersal and stability)?

Question 4

Explain levins model of patch dynamics and the equation for colonization rate (with graph)

Question 5

does metapopulation structure facilitate the persistence and coexistence of species (3 ways)

Question 6

Explain how the population of pikas persist based on metapopulation

Question 7

How do population get driven to extinction and how are they contradicted naturally?

Question 8

What is a metacommunity?

Question 9

What are the three things that determine the number of species on an island?

Question 10

Use the anolis lizard example to test this theory of island biogeography

Question 11

Explain the theory of island biogeography
