Population Ecology - Metapopulations. K. Metapopulations. 1. Multi-population systems. In recent times more than before, human populations expand and require larger areas for agriculture and other land-use goals, often at the expense of natural ecosystems. Many organisms have to face large-scale habitat destruction and fragmentation of larger populations.

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.

Challenges include whether seed dispersal is sufficient for population connectivity, the role of seed banks and problems with studying colonization and extinction in long‐lived and clonal plants. Examples of how to use “metapopulation” in a sentence from the Cambridge Dictionary Labs 20 May 2015 Thus far, metapopulations models have either taken a mean-field approach, or have modeled empirically-based, realistic landscapes. Here we  of population structures, and these breaks allow mean- Key words: deme, local population, metapopulation, population, species population, subpopulation. observe a true CM structure, this means that the focal metapopulation is on the brink of extinction and that drastic conservation measures are needed.

A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or artificially fragmented habitats.

For a given species, each metapopulation is continually being modified by increases (births and immigrations) and decreases (deaths and emigrations) of individuals, as well as by the emergence and dissolution of local populations contained within it. Från Wikipedia.

1997-01-01 · The word itself suggests a population of populations, with colonization and extinction of local populations in a metapopulation likened to births and deaths of individuals in a local population (hence the emphasis on population turnover in "classical" metapopulation studies). 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.

Populations outside of a network of connected populations either exist as isolated populations or belong to a separate metapopulation.
