A Scrutiny of the Levins Metapopulation Model
نویسنده
چکیده
The Levins metapopulation model describes the dynamics of several populations in patches of suitable habitat. These populations may go extinct, leaving empty patches of suitable habitat, but these empty patches may be recolonized by other populations via dispersal. The metapopulation can therefore persist if recolonizations balance local extinctions. This simple model has been criticized for its alleged simplicity, and it has been frequently extended to incorporate more realism. This article scrutinizes the assumptions of the Levins model to reveal its true simplicity. It turns out that many assumptions may be considerably weakened without affecting the model.

Introducing stage-specific spatial distribution into the Levins metapopulation model
The Levins model is a classical but still widely used metapopulation model that describes temporal changes in the regional abundance of a species by extinction and colonization of subpopulations. A fundamental assumption of the model is that the landscape is homogeneous and the species moves between identical patches at random. However, this assumption clearly contrasts with the common observat...
متن کاملTransient dynamics in metapopulation response to perturbation.
Transient time in population dynamics refers to the time it takes for a population to return to population-dynamic equilibrium (or close to it) following a perturbation in the environment or in population size. Depending on the direction of the perturbation, transient time may either denote the time until extinction (or until the population has decreased to a lower equilibrium level), or the re...
متن کاملAsymptotically exact analysis of stochastic metapopulation dynamics with explicit spatial structure.
We describe a mathematically exact method for the analysis of spatially structured Markov processes. The method is based on a systematic perturbation expansion around the deterministic, non-spatial mean-field theory, using the theory of distributions to account for space and the underlying stochastic differential equations to account for stochasticity. As an example, we consider a spatial versi...
متن کاملThe evolution of dispersal in a Levins' type metapopulation model.
We study the evolution of the dispersal rate in a metapopulation model with extinction and colonization dynamics, akin to the model as originally described by Levins. To do so we extend the metapopulation model with a description of the within patch dynamics. By means of a separation of time scales we analytically derive a fitness expression from first principles for this model. The fitness fun...
متن کاملGeneralizing Levins metapopulation model in explicit space: models of intermediate complexity.
A recent study [Harding and McNamara, 2002. A unifying framework for metapopulation dynamics. Am. Nat. 160, 173-185] presented a unifying framework for the classic Levins metapopulation model by incorporating several realistic biological processes, such as the Allee effect, the Rescue effect and the Anti-rescue effect, via appropriate modifications of the two basic functions of colonization and...
