METAPOPULATION DYNAMICS AND GENETICS. Annual Review of Ecology and Systematics Vol. 25:167-188 (Volume publication date November 1994) 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. I ﬁrst discuss the new perspective that metapopula- In fragmented landscapes, the evolutionary dynamics of adaptation may both decrease and enhance metapopulation viability in comparison with no evolution.

This paper describes a novel approach to modelling of metapopulation dynamics. The model is constructed as a generalized incidence function, which describes how the fraction of occupied habitat patches depends on patch areas and isolations.

Well established effects of habitat patch area and isolation on migration, colonization and population extinction have now become 1998-09-25 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.

We give here the graph theoretic and dynamical systems context in which metapopulation models are formulated. 2.1 Introduction Metapopulation ecology remains one of the most dynamic and active areas of population ecology!

Ecology and Society 14 Jan 2008 Abstract. I develop models of metapopulation dynamics that describe changes in the numbers of individuals within patches. These models are Metapopulation models consider local populations as individuals. Dynamics of local populations is either not considered at all, or is considered in a very Metapopulation dynamics The theory is very simple. The world is divided up into many patches, all of which are potentially habitable. Populations on inhabited 19 Oct 2016 Metapopulation ecology has provided a powerful set of tools for applied conservation (Soulé et al., 1988), and is ideally suited for modeling 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.
