which is a requirement for the existence of a metapopulation?i. a system of habitat corridors that link individual populationsii. the presence of both r- and k-selected speciesiii. variation in the size of individual populations

Respuesta :

These separated populations are linked by strips of natural niche that are known as corridors. The demand for the actuality of a metapopulation is a system of niche corridors that link individual populations.

Astronomically speaking, a metapopulation is a group of populations( frequently called * subpopulations) that enthral spatially distinct niche patches that are close enough to support disbandment among patches. We frequently suppose similar models as “ spatially structured ” or “ spatially unequivocal ”, although some metapopulation models( like the models considered below, and in the Gotelli text) use a rather abstract representation of space!

Now that we ’re allowing creatures living in particular areas in space, we need to incorporate information about movement ecology in addition to population ecology! Patches in a metapopulation are connected viadispersal. However, it wouldn’t really be a metapopulation, but rather a set of insulated populations that you could model singly, If there were no connectivity( disbandment among patches).
