Apopulation is a group of individuals of a single species existing together in an area. a population’s range, the area it occupies, changes over time. populations, in turn, may form a network, or metapopulation, connected by individuals that move from one group to another. within a population, the distribution of individuals can be random, uniform, or clumped, and the distribution is determined in part by the availability of resources. how might the geographic range of a species change if populations could not exchange individuals with each other? how would your answer depend on what type of metapopulation existed?
