population dynamics

Biology

The study of the fluctuations that occur in the numbers of individuals in animal and plant populations and the factors controlling these fluctuations. Changes in numbers depend on rates of births, deaths, emigration, and immigration (see population growth). An important distinction is between controlling factors that are dependent on population density and have a stabilizing effect (e.g. food supply) and those that are independent of population density (e.g. catastrophes, such as flooding). Fluctuations of certain predators may follow those of their prey in fairly regular population cycles.

Geography

The study of the numbers of populations and the variations of these numbers in time and space. The main determinants are birth and death rates and migration; which, in turn, reflect levels of development, and socio-economic and cultural factors. See Millington et al. (1999) App. Geog. 19, 4 on population dynamics and socio-economic change; Bhandari and Grant (2007) J. Rural & Comm. Dev. 2 on population dynamics and land use; Ahn in H.-R. Kim and B. Song (2007) on population dynamics and urbanization in Korea. See also H. Macbeth and P. Collinson, eds (2002); try L. M. Hinter (2000) on the environmental implications of population dynamics. For geolinguists, see N. Komarova and M. Nowak (2002) on the population dynamics of grammar acquisition.
