WebThis smooth curve is called a density curve and can be thought of as the theoretical version of the population histogram. Density curves also provide a way to visualize probability distributions such as the normal distribution. A normal density curve is superimposed on the histogram above.

WebAt each t, fX(t) is the mass per unit length in the probability distribution. The density function has three characteristic properties: (f1) fX ≥ 0 (f2) ∫RfX = 1 (f3) FX(t) = ∫t − ∞fX. A random variable (or distribution) which has a density is called absolutely continuous. This term comes from measure theory.

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). WebWhen a population reaches a high density, there are more individuals trying to use the same quantity of resources.
