Which of the following is a major conclusion of the Levins metapopulation
model? Select all that apply.
?Decreasing the number of potential habitat patches will decrease population growth
?At equilibrium, species could, in theory, occupy all potential patches in this model.
?At equilibrium, there will always be some patches that are unoccupied in the
environment
?There can be an \"extinction threshold\" where a metapopulation will go extinct when
a certain number of patches are removed
