By contrast, interspecific competition occurs when members of different species compete for a shared resource. Members of the same species have rather similar requirements for resources, whereas different species have a smaller contested resource overlap , resulting in intraspecific competition generally being a stronger force than ...
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 .
Concerning the possibility that competition has led to segregation in the evolutionary past, Wiens (1974, 1984) [65] [66] concluded that such assumptions cannot be proven, and Connell (1980) [67] found that interspecific competition as a mechanism of niche segregation has been proven only for some pest insects.
Interspecific competition, when individuals of different species compete for the same resource in an ecosystem; Interspecific feeding, when adults of one species feed the young of another species; Interspecific hybridization, when two species within the same genus generate offspring. Offspring may develop into adults but may be sterile.
According to competitive-relatedness hypothesis (Cahil et al., 2008 [19]) or phylogenetic limiting similarity hypothesis (Violle et al., 2011 [20]) interspecific competition [21] is high among the species which have similar functional traits, and which compete for similar resources and habitats.
This model conditions for coexistence can be directly related to the general coexistence criterion: intraspecific competition, α jj, must be greater than interspecific competition, α ij. The direct expressions for intraspecific and interspecific competition coefficients from the interaction between shared predators and resources are
