Consider a metapopulation of iguanas inhabiting a chain of small islands off the coast of South America. In year 1, there are iguanas on 15 of the 60 islands. The probability of a given empty island being colonized in a given year is 0.11, and the probability of the population going extinct on any particular occupied island in a given year is 0.12.   In year 1, what will be the rate of change in the proportion of islands occupied by iguanas, based on the Levins metapopulation model?                              Determine the number of islands that should be occupied when the metapopulation reaches equilibrium.                    Should this metapopulation go extinct, or should it persist?

Population Growth

R and K Selection

R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.
