Population model

A population model is a type of mathematical model that is applied to the study of population dynamics.

A population model is a type of mathematical model that is applied to the study of population dynamics. ==Rationale== Models allow a better understanding of how complex interactions and processes work. Modeling of dynamic interactions in nature can provide a manageable way of understanding how numbers change over time or in relation to each other. Many patterns can be noticed by using population modeling as a tool. Ecological population modeling is concerned with the changes in parameters such as population size and age distribution within a population. This might be due to interactions with the environment, individuals of their own species, or other species. Population models are used to determine maximum harvest for agriculturists, to understand the dynamics of biological invasions, and for environmental conservation. Population models are also used to understand the spread of parasites, viruses, and disease. Another way populations models are useful are when species become endangered. Population models can track the fragile species and work and curb the decline. : \frac{dN}{dt} = rN\left(1-\frac{N}{K}\right)\, Competitive Lotka–Volterra equations: \frac{dN_1}{dt} = r_1 N_1\frac{K_1-N_1 - \alpha N_2}{K_1}\, Island biogeography: S = \frac{IP}{I+E} Species–area relationship: \log(S) = \log(c)+z \log(A)\, ==External links== [https://web.archive.org/web/20120211165831/http://iugo-cafe.org/greenboxes GreenBoxes code sharing network.
