Sufficient condition for dispersal-induced growth on dynamic networks
Michel Benaïm, Claude Lobry, Tewfik Sari +1
We consider a population spreading across a finite number of sites. Individuals can move from one site to the other according to a network (oriented links between the sites) that v…

Dispersal-induced growth or decay in a time-periodic environment. The case of reducible migration matrices
Michel Benaim, Claude Lobry, Tewfik Sari +1
This paper is a follow-up to a previous work where we considered populations with time-varying growth rates living in patches and irreducible migration matrix between the patches.…

When can a population spreading across sink habitats persist ?
Michel Benaim, Claude Lobry, Tewfik Sari +1
We consider populations with time-varying growth rates living in sinks. Each population, when isolated, would become extinct. Dispersal-induced growth (DIG) occurs when the populat…
