title: On the stabilizing effect of predators and competitors on ecological communities.
abstract: Ecological communities can lose their permanence if a predator or a competitor is removed: the remaining species no longer coexist. This well-known phenomenon is analysed for some low dimensional examples of Lotka-Volterra type, with special attention paid to the occurrence of hetero-clinic cycles.
