Such models easily reflect the direct impact of one population upon the other - for example, the production by one population of a metabolic product that inhibits the growth of the other. The simplest form of competition, however, occurs when two or more populations compete for the same resource, such as a common food supply or a growth-limiting nutrient. This is called exploitative competition. A simple example of this type of competition occurs in a laboratory device, called a chemostat or...

Another possibility is to use xenon-arc lamp irradiation for the same purpose, which extends the possibilities of excitation wavelengths to the 272-382-nm range. Exploiting competitive binding of trace amounts of (misused) drugs with fluorescence-labeled immunotracers can be spotted in the literature however, this is not a widely used approach at the moment. 

A different type of competition interaction is the case in which the growth rates of two competitors depend linearly on the same resource R(B, B2) (exploitative competition) ... 

Factors that drive the process of succession include interspecies competition, environmental conditions, inhibition, and facilitation. In a developing ecosystem, species compete for scarce resources. The species that compete most successfully dominate. Environmental conditions, as previously discussed, influence species viability. Finally, the activities of certain species can inhibit or facilitate the growth and development of other species. Inhibition results from exploitative competition or interference competition. In facilitation, a species or group of species lays the foundation for the establishment of other, more advanced species. For example, the presence of a certain bacterial population can change the pH of the soil, allowing for the growth of different types of plants and trees. 

In order for multiple enterprises to collaborate around an idea (e.g. the notion of a virtual enterprise), decision tools must be designed that help identify and exploit competitive and comparative advantages of partnerships. Parker [57] gives an example of a Father s Day gift developed from the formation of a coalition of a TurtleWax product with a Hallmark card packaged by an out-... 

Interference competition embraces any activity which directly or indirectly limits a competitor s access to a resource (Miller, 1967). Indirect interference invariably involves a form of chemical communication, or signal, which is effective in the owner s absence. Direct interference includes a range of interactions such as territoriality, dominance, physiological or physical suppression, and cannibalism. Exploitation is the joint utilization of a limited resource once access has been gained (Miller, 1967). Thus, rather than deal with other individuals, an exploiter deals exclusively with available resources and is successful only through competitive ability. Nicholson (1954) proposed a comparable, but not identical, distinction between modes of competition by designating contest and scramble competition, terms which relate to interference and exploitation competition, respectively.
