Disease dynamics in metapopulations
Structured populations are of particular interest when discussing disease dynamics. A common approach is to consider metapopulations: a group of coupled, well-mixed patches (also called (sub)populations or households). Two, frequently used ways to realize coupling are to introduce between-patch contact rates and to allow migration. Although these two ways describe different real-life situations...
متن کاملExtinction dynamics in experimental metapopulations.
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 extin...
متن کاملOn fitness in structured metapopulations.
In this paper we derive a general expression measuring fitness in general structured metapopulation models. We apply the theory to a model structured by local population size and in which local dynamics is explicitly modelled. In particular, we calculate the evolutionarily stable dispersal strategy for individuals that can assess the local population density in the case where only dispersal is ...

متن کاملA persistence criterion for metapopulations.
Simple conditions to evaluate the persistence of populations living in fragmented habitats are of primary importance in ecology. We address this need here using a spatially implicit approach that accounts for discrete individuals in a metapopulation. Demographic stochasticity is incorporated into a Markovian model in a natural way, as local extinction is characterized by the death or the disper...
