Are these assumptions always met in natural systems?

Density dependent factors are environmental factors that limit the population when it reaches a certain density. Some examples of density dependent factors that ... Here we report on both density-dependent and density-independent effects in a murid rodent pest species, the multimammate rat Mastomys natalensis. As population density increases the amount of deer food in the area declines; this decline in food affects deer body condition. Body condition serves as a ... The persistence of prey encountering intense predation varies by species, prey density, and habitat type; however, the collective impact of these factors has ... I suggest that both density-dependent and independent factors operate simultaneously on wild turkey populations, where the relative strength of each is governed ... Identify the concept of density-dependent limiting factors, which are factors that affect population growth and become more intense as the population density ... Jun 19, 2021 ... Uthe et al. (2019) provided evidence of both DD and DI effects on Yellowstone Cutthroat Trout growth dynamics, where factors such as temperature ... The Ghost of Density-Dependence: Environmental (Hydrological) Factors Drive the Numerical Changes of Young Migratory Trout Salmo trutta in a Lake District ... PDF | On Jan 9, 2020, S. Furuichi and others published Disentangling the effects of climate and density-dependent factors on spatiotemporal dynamics of ... Density-dependent factors change in intensity based on population size, acting as a form of population regulation, while density-independent factors can cause ...
