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 among members of the same species is known as intraspecific competition, while competition between individuals of different species is known as interspecific competition. According to the competitive exclusion principle , species less suited to compete for resources must either adapt or die out , although competitive exclusion is ...
Competition is often for a resource such as food, water, or territory in limited supply, or for access to females for reproduction. [18] Competition among members of the same species is known as intraspecific competition , while competition between individuals of different species is known as interspecific competition .
For example, a slight modification of the assumption of how growth and body size are related leads to a different conclusion, namely that, for a given ecosystem, a certain range of species may coexist while others become outcompeted. [10] [11] One of the primary ways niche-sharing species can coexist is the competition-colonization trade-off ...
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 ]
A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
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 ...
The crab-coral interaction described above is also an example of refuge from competition, since the herbivory of crabs on seaweed reduces competition between coral and seaweed. [12] Similarly, herbivory by sea urchins ( Strongylocentrotus droebachiensis ) on kelps ( Laminaria spp.) can protect mussels ( Modiolus modiolus ) from overgrowth by ...
