WitrynaSome are density-dependent, while others are density-independent. Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. One example is … WitrynaPopulation dynamics often depend on density-dependent factors, which influence a population’s growth rate based on the population’s size. Many of these factors are negative density-dependent, meaning that they reduce the population growth rate as the population gets bigger and thus limit the population’s size.

WitrynaInside the fence, red kangaroo and emu populations showed a 'typical' post-drought recovery. The data therefore suggest that, in some situations, dingoes may not simply limit red kangaroo and emu populations, but also regulate them. For this to occur, predation rate would need to be density dependent at low prey densities. Witrynad. habitat. d. habitat.

Scramble competition for food affects viability and adult size, which are correlated with the fecundity of females. Adult effects on fecundity are also explicitly modeled. In the two submodels considered, changes in the minimum amount of food …
