Competition in ecosystems has become central to the study of ecology, and has been implicated as a major factor behind the patterns of species abundance and distribution. Though often studied together, abundance and distribution are two distinct designations, abundance being the density of a species in a given area, and the spatial arrangement of that species in an area is referred to as the distribution (Brown, 1984). In ecological terms competition refers to a fight between two organisms, of the same species or different, for a limiting resource, leading often to an adverse effect on one or both organism (Birch, 1957). When one of the organisms in the competition out competes the other for the desired resource this results in a negative consequence on the other species. The negative consequence can be either a reduction its population size and/or growth rate, which in turn effects the population abundance and distribution (Schoener, 1982). The limiting resource in question might be food, nutrients, habitat, or mates, anything for which the demand is higher than the supply (Schoener, 1982). It has become apparent to researchers that even within competition there are varying classifications, divisible by species involved, and mechanism of action (Schoener, 1983). When competition occurs between two organisms of the same species, it is known as intraspecific competition, whereas interspecific competition denotes competition ensuing between two differing species (Park,…
