WebDensity-independent diseases (probability of occurrence does not change with density; human example = cancer) Density-dependent (possibly more influential in vertebrate dynamics?): Food Space (territories, denning sites, nest cavities) Density-dependent epizootics (disease epidemics; WebDensity dependence is a crucial regulation mechanism in population dynamics but is challenging to study empirically. We illustrate the use of integrated population models (IPMs) to study density dependence while offering a number of interesting possibilities to overcome some of these challenges.
