Abstract

The role of direct and delayed density dependence in generating population cyclicity are well established, but there remains uncertainty in how they interact with demographic vital rates to contribute to cyclic variation. This study reveals how the type of density dependence and its effect on demographic rates can generate spatiotemporal variation in cyclic dynamics, independent of changes in the strength of density dependence.
