Local populations may and do go extinct, but only to be replaced by recolonization from other local populations within the metapopulation. Increasing this area increases the probability of habitat occupancy and the stability of the metapopulation. As a result, the genetic variance in this metapopulation is likely to be less than in an undivided population. Populations outside of a network of connected populations either exist as isolated populations or belong to a separate metapopulation. Parameterisation of a spatially explicit metapopulation model remains elusive and estimates for these parameters will be difficult to obtain. This is a general metapopulation phenomenon, and not simply reinvasion. In this case, the survival of the metapopulation is dependent on immigration and colonisation of new habitat patches (host populations). The region occupied by the metapopulation remains undefined but its boundaries can be found where the connectivity between populations tend to zero. Continuous monitoring of genetic structure for several generations will provide further insight to the genetic dynamics of the metapopulation within this region. At generations 2 and 8, we analysed nine quantitative traits in six populations per metapopulation using families obtained by selfing. Although larger forest patches may provide core habitats and metapopulation sources for bats, small fragments support the same species assemblage found in the largest remnants. A metapopulation perspective on genetic diversity and differentiation in partially selffertilizing plants. They propose a nested hierarchy of vehicles for genes (individual, group, metapopulation) in which each level also includes a population of lower level units. Ultimately, testing a metapopulation dynamic explanation would require a ranking of species dispersal abilities that are too little known. Four specific predictions of metapopulation theory in relation to community dynamics were tested. However, they can be easily accommodated into game theory and metapopulation models. Selection, load, and inbreeding depression in a large metapopulation. Inbreeding depression and genetic rescue in a plant metapopulation. Preserving genes : a model of the maintenance of genetic variation in a metapopulation under frequency-dependent selection. |
