Population Dynamics

Density-Dependent

Factors whose effects on population growth vary with population density. Competition, predation, and disease typically have stronger effects at higher densities.

Biological Context

At high density, individuals compete more intensely for food, making starvation more likely. Disease spreads faster in crowded populations. Predators focus on common prey. Density-dependent factors regulate populations, preventing unlimited growth but also preventing extinction.
