Metapopulation theory provides a framework for understanding population persistence in fragmented landscapes and as such has been widely used in conservation biology to inform management of fragmented populations. However, classical metapopulation theory [Levins, R. (1970) Lect. Notes Math. 2, 75-107] ignores metapopulation structure and local population dynamics, both of which may affect View Academics in Metapopulation Theory on Academia.edu. Metapopulation theory developed in terrestrial ecology provides applicable frameworks for interpreting the role of local and regional processes in shaping species distribution patterns. Yet, empirical testing of metapopulation models on microbial communities is essentially lacking. We determined reg … In classical metapopulation theory the landscape consists of only two types of patches: occupied patches and suitable but empty patches (Levins, 1969, 1970; The concept of metapopulation was introduced by Richard Levins (an American ecologist) in 1969.

This theory dealt with species richness of communities. Metapopulation Theory: A metapopulation consists of a set of sub-populations, occupying distinct habitat patches and connected through the dispersal, migration or human-mediated movement of individuals between patches (Young, 1999; Foster et al., 2017), as shown by Figure 1.
Using metapopulation theory, we have investigated the habitat requirements, colonization- extinction dynamics and per- sistence of old-oak-associated epiphytic
Written by a world renowned biologist, this volume offers a comprehensive synthesis of current research in this rapidly expanding area of population biology. This intuition forms the core of metapopulation theory: even though local populations occupying patches of suitable habitat might undergo extinction, persistence can be achieved at the metapopulation level—rather than in each patch—as long as individuals can disperse between patches and thus recolonize empty ones [ 1 ]. Island biogeography theory is based on a situation in which a mainland source population not threatened with extinction exists; metapopulation dynamics deal with situations in which the source population has been reduced to a set of small semi-isolated populations. This paper explores the applications of both theories to conservation practice.
Another valuable addition to metapopulation theory is the assumption that immigration is not from local populations, but from a constant propagule rain (Gotelli 1991), or dormant seedbank. This makes colonization rate independent of P, as in island - mainland systems.
2. Metapopulation Ecology Ilkka Hanski Oxford Series in Ecology and Evolution. Written by a world renowned biologist, this volume offers a comprehensive synthesis of current research in this rapidly expanding area of population biology. 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.

One of them is the incorporation of variation in population size. This makes these deterministic models stochastic, which results in a stable equilibrium 0 < P' < 1, in stead of 0 or 1. Metapopulation, originally pioneered by Levins, refers to a series or set of local populations, each existing on a patch of suitable habitat that is separated from other occupied patches by unsuitable terrain. 2015-05-20 2015-07-01 when metapopulation theory is extended to examining interactions among species, it is termed.

Using this theory, we may also calculate how the metapopulation capacity is changed by removing habitat fragments from or adding new ones into specific spatial locations, or by changing their areas. The metapopulation capacity should find many applications in metapopulation ecology, landscape ecology and conservation biology.
