WebPopulation Size, Density, and Distribution. Communities are made up of populations of different species. In biology, a population is a group of organisms of the same species that live in the same area. The population is the unit of natural selection and evolution. How large a population is and how fast it is growing are often used as measures ... WebApr 10, 2024 · Density-dependent habitat selection. Many models of habitat selection result in animals changing their spatial distribution as total abundance increases (Avgar et al. 2024). For example, density-dependent habitat selection can result in local responses to population abundance that vary across space (MacCall 1990).
