How might the loss of a key predator affect density-dependent control in a food web? How are density-dependent factors incorporated into models of species interactions?

Oct 21, 2005 ... Temperature, precipitation, topography, soil, and predators are examples of powerful ecological factor groups that operate as density-dependent ... Summary. 1. There has been increasing recognition that catastrophes are an important factor in modelling threatened populations. However, density dependence ... Oct 19, 2023 ... Density-dependent limiting factors tend to be biotic—having to do with living organisms. Competition and predation are two important examples of ... Apr 6, 2016 ... In real-life situations, population regulation is very complicated and density-dependent and independent factors can interact. A dense ... Here we report on both density-dependent and density-independent effects in a murid rodent pest species, the multimammate rat Mastomys natalensis. The density-independent factors are known as limiting factors in the population ecology. Earthquakes, fires, floods, and tornados are the factors of the density ... Limiting factors operate to depress a population without regard to its number; limiting fac- tors are density independent. Regulating factors are spe- cial ... Feb 15, 2024 ... Population density is one of the key factors affecting dispersal patterns. The relationship between natal dispersal and population density ... We define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the ... Jun 13, 2013 ... Effects of the density-dependent weak form factors on the neutrino reaction via neutral current for the nucleon in nuclear matter and 1 2 C.
