Population responses to environmental disturbance

  • Chapter
Disturbance in Grasslands

Part of the book series: Geobotany ((GEOB,volume 10))

Abstract

The term ‘population’ is used in several biological contexts and, if confusion is to be prevented, we need first to define the context. Leaving aside the misuse of the term as a synonym for ‘density’, there are two main uses of the term ‘population’. Firstly, it is used in a genetical context, sometimes termed ‘Mendelian population’, to indicate a group of individuals, normally of the same species, which interact reproductively, i. e. exchange genes. Secondly, it is used in an ecological context to indicate a group of individuals of the same species that interact ecologically, mainly by competition. In each case, unless the group of individuals is geographically isolated, it is usually not possible to clearly define the boundary of the population. As a result, the group is ill-defined, and the term population is therefore normally used very loosely.
