To increase our understanding of metapopulation dynamics in static and dynamic landscapes, quantitative models are useful tools. They can be used to predict the response of species to a changing environment, or in conservation planning (Bascompte and Solé 1998, Hanski 1999, Akçakaya and Sjögren-Gulve 2000, Beissinger and McCullough 2002). metapopulation dynamics, habitat patch area and iso-lation, and to what extent other factors possibly im-prove the predictive power of metapopulation models. Spatial variation in the environment can conceivably affect metapopulation dynamics in many different ways (Murphy et al. 1990).

Metapopulation dynamics

At the level of a single patch, It thus follows that adopting a landscape ecological perspective to metapopulation dynamics entails understanding how a spatial pattern, such as habitat fragmentation or heterogeneity, affects the Simulations of future metapopulation dynamics resulted in decreasing and lower final occupancy in production forest than in set-asides, especially of specialist species. In set-aside stands Metapopulation, in ecology, a regional group of connected populations of a species. 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.

Metapopulation dynamics in a broad sense are not restricted to systems with population turnover, extinctions and colonizations, but the concept developed here is based on Levins’s classic meta-population idea with extinction-prone populations in discrete habitat patches.

Now that we’re thinking about animals living in particular areas in space, we need to start thinking about movement ecology in addition to population ecology !

However, we need further information on metapopulation dynamics to inform decisions on whether sites should be restored and, if so, which ones. Without this information, restoration attempts may create ecological traps that lure birds to sites at which they fail to produce sufficient surviving offspring due to predation and poor food availability (Kristan, 2003 ).

Departments of Entomology and Biology, Pennsylvania State Metapopulation biology is concerned with the dynamic consequences of migration among local populations and the conditions of regional persistence of species with unstable local populations. Metapopulation studies have important conceptual links with the equilibrium theory of island biogeography and with studies on the dynamics of species living in patchy environments. Metapopulation ideas play an increasingly important role in landscape ecology and conservation biology.

The key concept here is that different populations within the metapopulation are connected by dispersal but are undergoing different dynamics, but are connected by dispersal. To increase our understanding of metapopulation dynamics in static and dynamic landscapes, quantitative models are useful tools.

Metapopulation is a population in which individuals are spatially distributed in a habitat to two or subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation .

Metapopulation ideas play an increasingly important role in landscape ecology and conservation biology. 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.

Metapopulation ecology remains one of the most dynamic and active areas of population ecology! Broadly speaking, a metapopulation is just a spatially structured population. Now that we’re thinking about animals living in particular areas in space, we need to start thinking about movement ecology in addition to population ecology !

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.
