Abstract
We consider a single-species model which is composed of several patches con nected by linear migration rates and having logistic growth with a threshol d. We show the existence of an aggregating mechanism that allows the surviv al of a species which is in danger of extinction due to its low population density. Numerical experiments illustrate these results. (C) 2000 Elsevier Science Inc. All rights reserved. MSC: 92D25; 34A34.
