Abstract

Dispersal is a key ecological process, that enables local populations to form spatially extended systems called metapopulations. In the present study, we investigate how dispersal affects the stability of a general metapopulation model. We find that dispersal impacts the stability of metapopulations through local patches dynamics and various dispersal behaviors (positive density-dependent dispersal, costly dispersal, social fencing of immigrants and settlement facilitation). We also show that in homogeneous metapopulations, a density-independent dispersal does not affect stability, whereas in heterogeneous ones it can yield an impact on stability, that is modulated by the spatial structure of the metapopulation.
