The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize popula- tions around the carrying capacity.

High densities in a population may cause physiological changes that inhibit reproduction.
Because of the overlapping nature of population-regulating factors, it is often difficult to precisely deter- mine their cause-and-effect relationships.
