How do metapopulations change through time: habitat preference of species are restricted & individuals occupt only isolated within that broad area, metapopulations: individuals from a species occupy many small patches of habitats which forms independent populations. They are considered metapopulations- population of populations: because humans are reducing large, areas of forest & grassland to isolated patches or reserves, more & more species are being forces into metapopulation structures. Metapopulations should be dynamic: there is a balance b/t enxtinction & recolonization withing a metapopulation. Even though subpopulation blink on and off over time, the overall population is maintained at a stable number of individuals: metapolution is made up of small, isolate population. The overall size of metapopulations stay stable even if subpopulations go extinct.
