Give an example of an Allee effect. How do density-dependent factors affect population distribution and dispersal?

Feb 15, 2024 ... Population density is one of the key factors affecting dispersal patterns. The relationship between natal dispersal and population density ... Density-dependent factors are environmental influences that depend on population size or density, such as competition for resources, predation, and disease. They also use data from other species to learn how density-dependent factors limit population size. The Click & Learn includes realistic and actual data ... Here we report on both density-dependent and density-independent effects in a murid rodent pest species, the multimammate rat Mastomys natalensis. Apr 8, 2003 ... An increasing population of the mute swan Cygnusolor, was studied from its very establishment in 1976 until 1998. Jun 30, 2020 ...

May 17, 2017 ... ... density interacting with environmental factors (i.e. refugia, competition and predation). 2.3. Experiment 1: density-dependent larval survival. The persistence of prey encountering intense predation varies by species, prey density, and habitat type; however, the collective impact of these factors has ... Most density-dependent factors are biological in nature (biotic), and include predation, inter- and intraspecific competition, accumulation of waste, and ...
