Dispersal-induced growth in a time-periodic environment of sink habitats
Abstract
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 populations are able to persist and grow exponentially when dispersal among the populations is present. We provide a mathematical analysis of this phenomenon, in the context of a deterministic model with periodic variation of growth rates and migration.
