TL;DR: This work addressed the question of the coexistence of specialist and generalist species with a spatially explicit metacommunity model in continuous and heterogeneous environments by characterized how species’ dispersal abilities, the number of interacting species, environmental spatial autocorrelation, and disturbance impact community composition.

TL;DR: A Monte Carlo simulation model is developed that suggests that metapopulation extinctions are more likely when dispersal is asymmetric, and has important implications for managing spatially structured populations, when asymmetric dispersal may occur.

TL;DR: The model and data from Timema populations provide evidence for a simple mechanism through which parthenogenesis can evolve rapidly in a sexual population, consistent with the idea that low densities of individuals result in mate limitation and selection for reproductive insurance through tychoparthenogenesis.

TL;DR: In this paper, a method based on a geographical information system (GIS) to model ecological networks in a fragmented landscape is presented, which allows the analysis and understanding of the impact of human activities on wildlife dispersal.

TL;DR: This work considers how metapopulation persistence is affected by different disturbance regimes and the way in which disturbances spread, when meetapopulations are compact or elongated, using a stochastic spatially explicit model which includes metapoulation and habitat dynamics and discovers that the risk of population extinction is larger for spatially aggregated disturbances than for spatually random disturbances.
