Competition is an interaction between organisms or species in which both require one or more resources that are in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. [2]
In ecology, contest competition refers to a situation where available resources, such as food and mates, are utilized only by one or a few individuals, thus preventing development or reproduction of other individuals. It refers to a hypothetical situation in which several individuals stage a contest for which one eventually emerges victorious.
An example of direct competition. Intraspecific competition is an interaction in population ecology , whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. [ 1 ]
Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis. Competition between members of the same species is called intraspecific competition.
The iGEM (International Genetically Engineered Machine) competition is a worldwide synthetic biology competition that was initially aimed at undergraduate and 'overgraduate' university students, but has since expanded to include divisions for high school students, entrepreneurs, and community laboratories. iGEM is presented as "the heart of synthetic biology" - educating the next generation of ...
Example: Let α −2 = 0.451, α −1 = 0.5, and α 2 = 0.237. If α 1 = 0.5 then all eigenvalues are negative and the only attractor is a fixed point. If α 1 = 0.852 then the real part of one of the complex eigenvalue pair becomes positive and there is a strange attractor. The disappearance of this Lyapunov function coincides with a Hopf ...
AI, for example, is poised to revolutionize materials science by screening candidate compounds at superhuman speeds to better predict which ones are most likely to exhibit desirable properties.
Scramble competition also exists in lepidopterans. For example, male mourning cloak butterflies will fly around in search for widely dispersed females. [12] Another example of scramble competition exists in Lactrodectus hesperus, the western black widow spider. There is a male-bias or skew within the sexually active population of this species ...
