The Competitive Exclusion Principle: Gause's Principle, Effects of the Competitive Exclusion Principle

Introduction Competition between individuals or species chances when there be limited resources that must be sha release. It is an interaction in which mavin existence deprives other of resources, for ex vitamin Ale food; water; nesting space, and causes a reduction in fitness i.e. reduced growth, fewer progeny, and greater risk of termination of the weaker species (employees.csbsju.edu). Competition is expresed by all exploitation, in which one organism will use up shared resources, or impediment whereby animals keep others international from resources by fighting or by aggressive displays (Krebs & Davies, 1993). When exhibited between dickens different species it is called interspecific contention, and intraspecific when between individuals of the same species. For competitive elision to occur interspecific aspiration must be greater than intraspecific (Begon et al., 1996). Gauses Principle Competitive exclusion or Gauses Principle is the well-nigh severe outc ome of interspecific competition that leads to the extinction or removal from the habitat of the weaker species (Reitz & Trumble, 2002). It occurs when ii species share a very similar or same niche inside the habitat, in that they use the same resources in the same ways. The to a greater extent similar the needs shared by the species the more fervent the competition (Oosting, 1956).

Inevitably one of the two species will ever have a slight good over the other, either by better utilization or defence of resources, and thus out-competes the weaker species, causing exclusion from the habitat, by either extinction of the species, or extinction from the area. This principle can ofttime s be discover when non-native invading spec! ies drive native species to extinction, or competitive displacement, with their superior competitive ability (www.tiem.utk.edu), and absence of environmental stops. For example, red squirrel populations in Britain have plummeted mainly delinquent to competitive exclusion (also influenced by other factors such as disease, and habitat disappearance). The...
