Question 2

What is 2 characteristics of meta-populations?

Answer 2

Local Extinction is a natural process in meta-populations dynamic
Recolonization allows for meta-populations persistence

Question 3

Write the probability of regional persistence formula with the 2 variables, and explain what these 2 variables are.

Answer 3

P_x = 1-(p_e)^x

P_x : Probability of regional persistence of a set of x patches.

p_e : Probability of extinction for any given patch

Question 4

Draw the extinction vortex with its 4 parts, including what things affect the parts.
