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 .
Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
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.
The lower portion of the range was limited by interspecific interactions, namely competition with a cohabiting barnacle species and predation by a snail. [78] By removing the competing B. balanoides , Connell showed that C. stellatus was able to extend the lower edge of its realized niche in the absence of competitive exclusion .
Biological interactions are the interactions of organisms in an ecosystem. ... Interspecific competition; Intraguild predation; Intraspecific competition;
Intraguild predation is common in nature and widespread across communities and ecosystems. [2] Intraguild predators must share at least one prey species and usually occupy the same trophic guild, and the degree of IGP depends on factors such as the size, growth, and population density of the predators, as well as the population density and behavior of their shared prey.

The main subfields of evolutionary ecology are life history evolution, sociobiology (the evolution of social behavior), the evolution of interspecific interactions (e.g. cooperation, predator–prey interactions, parasitism, mutualism) and the evolution of biodiversity and of ecological communities.
A synomone is an interspecific semiochemical that is beneficial to both interacting organisms, the emitter and receiver, e.g. floral synomone of certain Bulbophyllum species (Orchidaceae) attracts fruit fly males (Tephritidae: Diptera) as pollinators, so can be classed as an attractant.
