On 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 کاملEvolution of Specialization on Re- source Utilization in Structured Metapopulations
We study the evolution of resource utilization in a structured discrete time metapopulation model with an infinite number of patches, prone to local catastrophes that wipe out the entire local population but leave the patch itself habitable. We assume that there are two distinct resources in each patch and the strategy of an individual is the degree of specialization on the usage of these resou...
متن کاملVertically transmitted symbionts in structured host metapopulations.
We develop a structured metapopulation model for vertically transmitted symbionts in natural host populations. We focus primarily on two questions: Are mutualism and high transmission probability prerequisites for the survival of symbionts in structured host metapopulations? What are the ecological conditions under which coexistence of infected and uninfected hosts is possible? We start with st...
متن کاملEvolution of specialization in resource utilization in structured metapopulations.
We study the evolution of resource utilization in a structured discrete-time metapopulation model with an infinite number of patches, prone to local catastrophes. The consumer faces a trade-off in the abilities to consume two resources available in different amounts in each patch. We analyse how the evolution of specialization in the utilization of the resources is affected by different ecologi...
متن کاملEvolutionary suicide and evolution of dispersal in structured metapopulations.
We study the evolution of dispersal in a structured metapopulation model. The metapopulation consists of a large (infinite) number of local populations living in patches of habitable environment. Dispersal between patches is modelled by a disperser pool and individuals in transit between patches are exposed to a risk of mortality. Occasionally, local catastrophes eradicate a local population: a...
