In various settings the authors show how behavior can be a response to heterogeneity, introducing nonlinear density dependence and qualitatively altering population dynamics. Also, even simple behaviors can cause nonadditivity, which is an interaction between environmental and density-dependent processes. It has a critical effect on the coexistence of competing species. To understand these various joint effects of behavior and heterogeneity on population dynamics, the general effects of behavior on dynamics are discussed. The authors then consider examples of the various ways in which heterogeneity affects dynamics, and for each example consider the interaction of behavior with heterogeneity. -from Authors
