Consequences of varying regional heterogeneity in source-sink metacommunities

Article Abstract:

A mechanistic model of resource competition in a metacommunity based on classical models of plant competition for limiting resources is presented to study the effects of dispersal and regional heterogeneity among local communities. The model shows how the effects of dispersal depend on the amount of heterogeneity among local communities and vice versa.

Coexistence, saturation and invasion resistance in simulated plant assemblages

Article Abstract:

Research indicates that saturation does not necessarily produce species richness, and is not likely to be an accurate predictor of a plant population's invasion resistance. Correlations between invasion resistance and species richness is dependent on the cause of the richness gradient and the specific model considered.

Community assembly time and the relationship between local and regional species richness

Article Abstract:

The consistent changes in the relationship between local and regional richness with assembly time in interacting communities are described. Habitat size and species are essential for the determination of time required to reach equilibrium.
