International Congress on the Theory and Mathematics in Biology and Medicine,. Amsterdam Analysis of a discrete metapopulation model, Math. Biosci.,. Metapopulation theory was first developed for terrestrial ecosystems, and subsequently applied to the marine realm. In fisheries science, the term "sub-population" is equivalent to the metapopulation science term "local population". Metapopulation theory states that a large population consisting of a single species is most stable over a large area when it is divided up into smaller subpopulations.

Metapopulation theory

Metapopulation theory is used to analyse the effects of habitat fragmentation on birds in the temperate zone, integrating various explanations for the paucity of species in isolated ecotopes. There is some evidence that turnover of local populations occurs in fragmented systems. Metapopulation theory suggests that additional patchiness may be caused by the dynamics of local extinctions and recolonisations.
