From random walks on networks to nonlinear diffusion.

Mathematical models of motility are often based on random-walk descriptions of discrete individuals that can move according to certain rules. It is usually the case that large masses concentrated in

Metapopulation Persistence in Random Fragmented Landscapes

This work derives a simple, analytic criterion for the persistence of the metapopulation in random fragmented landscapes, and derives sufficient conditions for the population to be spatially localized, such that spatially confined clusters of patches act as a source of dispersal for the whole landscape.

Complex Interactions in Metacommunities, with Implications for Biodiversity and Higher Levels of Selection

This computer simulation study examines the effect of complex interactions on the global and local dynamics of metacommunity dynamics, finding that complex interactions provide a new source of variation upon which natural selection can operate at the patch level, providing a mechanism for the evolution of more functionally organized communities.

Ecological and genetic basis of metapopulation persistence of the Glanville fritillary butterfly in fragmented landscapes

A metapopulation model is used to predict the distribution of the Glanville fritillary butterfly during 22 years across a large heterogeneous landscape with 4,415 small dry meadows to reflect eco-evolutionary dynamics.

Long-term research on eco-evolutionary spatial dynamics in the Glanville fritillary butterfly inhabiting a large network of approximately 4,000 meadows in Finland is reviewed.

Metapopulation structure and migration in the butterfly Melitaea cinxia

The modelling results demonstrate that it is possible to have empty habitat patches in a metapopulation in spite of frequent migration, as the butterfly M. cinxia was observed, and support the assumptions of structured metAPopulation models.

Connectivity structures local population dynamics: a long-term empirical test in a large metapopulation system.

The results provide the first comprehensive evidence that southern California giant kelp populations function as a metapopulation system, challenging the view that populations of this important foundation species are governed exclusively by self-replenishment.

Modern models of trophic meta-communities

The results show that the exact relationships between dispersal and foodweb dynamics are much more complex than previously thought, highlighting the need for further research in this area.

A metacommunity can be defined as a set of communities that are linked by migration, and extinction and recolonization, and the effect of these among-community-level processes depends on the pattern of migration among communities.

The biggest losers: habitat isolation deconstructs complex food webs from top to bottom

A dynamic and spatially-explicit food web model which integrates complex food web dynamics at the local scale and species-specific dispersal dynamics atThe landscape scale, allowing us to study the interplay of local and spatial processes in metacommunities.
