Define metapopulation. How does this concept relate to the spatial distribution (dispersion) of the population over a geographic region?

Answer: Metapopulation is a group of spatially separated populations of the same species that interact with each other through occasional movements (dispersal) of individuals from one subpopulation (patch) to another within a fragmented habitat. It relates to the spatial distribution of a population within a geographic region as it accounts for how different subpopulations of a species are distributed within fragmented habitats, and how their interactions influence the overall population dynamics. The spatial distribution is essential in metapopulation dynamics, as the distance between patches, their connectivity, and the suitability of surrounding habitats can impact dispersal rates and likelihood of successful colonization. A well-known example of a metapopulation is the Glanville fritillary butterfly in the Åland Islands in Finland.
