The relative importance of local and regional processes to

Metapopulation size N (subpopulation i = 1, 2, …, N). Metapopulation size defines the number of interacting subpopulations and is closely related to ecosystem size L (total river length of the watershed). The expected metapopulation size can be expressed as N = L/l. In metapopulation ecology, we are generally considering a landscape with a certain number of potentially habitable patches of habitat. A metapopulation is simply a population of patches , each of which may or may not be occupied by a species of interest at a given point in time. Metapopulations are conceived as spatially structured populations consisting of distinct units (subpopulations), separated by space or barriers, and connected by dispersal movements. Metapopulations characteristically demonstrate a turnover of local populations going extinct and becoming re-established, resulting in a distribution pattern that Ecology: Graduate Level; Meta-Population: - Concept of Metapopulation.- Dynamics of Metapopulation- Conditions for definition.- Types of metapopulation- Habi By forcing metapopulation dynamics on a formerly heterogeneous (but stable within subpopulations) population, the probability of simultaneous extinction of all subpopulations actually increases. Thus, it cannot be automatically assumed that increasing matrix quality will lower the probability of global extinction of a population.

Other approaches have been reviewed, for instance theore-tical work based on lattice models6,7,11–13 and conservation-oriented empirical studies14–16. The term ‘metapopulation’ is often used for The establishment and spread of a disease within a metapopulation is influenced both by dynamics within each population and by the host and pathogen spatial processes through which they are connected. We develop a spatially explicit metapopulation model to investigate how the form of host and diseas … ConservationMethods Using metapopulation theory for practical conservation of mangrove endemic birds Ryan Huang , 1∗ Stuart L. Pimm , and Chandra Giri2 1Nicholas School of the Environment, Duke University, Box 90328, Durham, NC, 27708, U.S.A. instead generates metapopulation dynamics in response to the empirically derived evolved individual-level life-history variation.

In this way, we show that the evolved trait variation especially impacts metapopulation size, but that most variation in the metapopulation dynamics is related to spatial forcing. Virtual invasion experiments We believe the concept of the metapopulation and metapopulation dynamics may provide insights into the persistence and conservation of species faced with habitat fragmentation as a consequence of military training or other land use (see Predicting the results of training and land management actions). Here, we investigate metapopulation-scale microbiome variation in a wild mammalian host, the desert bighorn sheep (Ovis canadensis nelsoni). We sought to identify over-represented microbial clades and understand how landscape variables and host traits influence microbiome composition across the host metapopulation.

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 Metapopulation dynamics are influenced by four kinds of stochasticity (Table 1): demographic and environmental stochasticity affecting separately each local population, and extinction–colonization and regional stochasticity affecting the entire metapopulation. Notice that the latter two forms of stochasticity are analogous to demographic and A metapopulation is a group of populations that are separated by space but consist of the same species. These spatially separated populations interact as individual members move from one Metapopulation structure assumed in the Levins model (1969): a large network of similar small patches, with local dynamics occurring at a much faster time scale than metapopulation dynamics; in a broader sense used for systems in which all local populations, even if they may differ in size, have a significant risk of extinction. Metapopulation is a population in which individuals are spatially distributed in a habitat in two or more subpopulations.

Therefore, metapopulation concepts replace the island biogeography concepts that Purchase Metapopulation Biology - 1st Edition. Print Book & E-Book.
