Habitat edges and predator-prey interactions: Effects on critical patch size

Research output: Contribution to journalArticlepeer-review

19 Scopus citations


We use partial differential equation models to examine the effects of cross-edge incursions by a predator on the persistence or extinction of a patch-resident prey species. For each of two predator-incursion profiles (namely, a constant incursion distance and a constant loss rate for predators during incursions), we examine the conditions under which the predator can (and cannot) influence the critical patch size of a prey species.
