WebNov 20, 2024 · Food in this case is an example of a density-dependent limiting factor. Density-independent limiting factors are factors that affect the per capita growth rate regardless of how dense a population is and include factors such as a flood, drought, and habitat destruction. Consider a flash flood occurs in the panther habitat.
WebA density-dependent factor is a factor whose effects on the size or growth of a population vary with the population density. Density-dependent factors typically involve biotic factors, such as the availability of food, parasitism, predation, disease, and migration. WebDensity dependent regulation was studied in a natural experiment with wild donkey populations on two sites in Australia. 2 On one site the population was reduced by a population control program; the population on the other site received no interference. The high-density plot was twice as dense as the low-density plot.
