Previous experiments have shown that for a specific experimental system of guppies (Poecilia reticulata), per capita growth rate is linearly related to population biomass. A length—specific population model is developed to examine how the various mechanisms of density dependence (i.e., changes in somatic growth rates, reproductive rates, and cannibalism) act in concert to shape the overall population response to intraspecific competition. Despite many nonlinear components, equilibrium per… Expand
