Playing next. From the Cambridge English Corpus. As a result, the genetic variance in this metapopulation is likely to be less than in an undivided population. From the Cambridge English Corpus. Populations outside of a network of connected populations either exist as isolated populations or belong to a separate metapopulation.

For the metapopulation dynamics with three states for the patch of a habitat composed of a number patches available for the reproduction, ‘vacant', ‘small' (i.e., threatened to the extinction) and ‘large' (i.e., far from the extinction risk) in terms of population size in the patch, we reconstruct the mathematical model in a general form, making use of the difference in time scale between the state transition and the dispersal of individuals within the patchy habitat. 1. A metapopulation consists of a group of spatially separated populations of the same species which interact at some level.

Enrich your vocabulary with the French Definition dictionary We then review recent applications of metapopulation models and summarize principles for applying metapopulation models in conservation planning. We end by identifying knowledge gaps that prevent broader applications of metapopulation models and by providing general research approaches for filling those gaps. 2015-07-15 · Background Population connectivity, which is essential for the persistence of benthic marine metapopulations, depends on how life history traits and the environment interact to influence larval production, dispersal and survival.
