Interspecific Competition vs. Intraspecific Competition | Sciencing
Interspecific scaling relationships (e. g. of limb size with body mass) in vertebrates are usu processes within species and ecological differences between them. Interspecific competition occurs between species, while intraspecific competition Symbiotic Relationships in the Temperate Grasslands. Intraspecific and interspecific competition are terms we use when talking about both biology and ecology. Both refer to situations in which organisms are.
The Interspecific and Intraspecific Relationships of Organisms in an Ecosystem
Commensalism is a relationship between species in which one of the organisms benefit from the relationship while the other organism is neither benefited nor harmed.
Mutualism is a relationship between organisms in which both species benefit from the relationship they are in to.
Parasitism is a relationship in which one organism benefit from the relationship while the other is harmed. Competition is a relationship in which the two or more species are competing with each other to utilize the same limited resources that are necessary in order for them to survive. Predation is a kind of relationship in which one form of species serves as food to the other species.
This involves a predator and prey relationship wherein specie is hunt by the other as food to eat. Amensalism is a kind of relationship in which one population of specie is inhabited while the other population of specie is not affected. The most dramatic form of interspecific competition occurs among mates. Similarities Between Interspecific and Intraspecific Competition Interspecific and intraspecific competition are two types of symbiotic relationships between species in a same ecological area.
They occur due to the limited resources in that ecological area such as food, mates, and territory. Both depend on the density of the population. Both types of competition can lead to evolution. Difference Between Interspecific and Intraspecific Competition Definition Interspecific competition refers to a form of competition between different species inhabiting the same ecological area while intraspecific competition refers to the competition for resources between members of the same species.
Competition The competition in interspecific competition is between members of different species while the competition in intraspecific competition is between the members of the same species.
Differentiate intraspecific relationship from interspecific relationship
This is the main difference between interspecific and intraspecific competition. This evolution may result in the exclusion of a species in the habitat, niche separationand local extinction. The changes of these species over time can also change communities as other species must adapt.
Gause's law The competitive exclusion principle, also called " Gause's law "  which arose from mathematical analysis and simple competition models states that two species that use the same limiting resource in the same way in the same space and time cannot coexist and must diverge from each other over time in order for the two species to coexist.
One species will often exhibit an advantage in resource use. This superior competitor will out-compete the other with more efficient use of the limiting resource. As a result, the inferior competitor will suffer a decline in population over time. It will be excluded from the area and replaced by the superior competitor.Interspecific population Interactions: Competition
A well-documented example of competitive exclusion was observed to occur between Dolly Varden charr Trout Salvelinus malma and white spotted char Trout S. Both of these species were morphologically similar but the former species was found primarily at higher elevations than the latter.
What is the Difference Between Interspecific and Intraspecific Competition
Although there was a zone of overlap, each species excluded the other from its dominant region by becoming better adapted to its habitat over time. In some such cases, each species gets displaced into an exclusive segment of the original habitat. Because each species suffers from competition, natural selection favors the avoidance of competition in such a way.
Niche differentiation Niche differentiation is a process by which competitive exclusion leads to differences in resource use. In the previous example, niche differentiation resulted in spatial displacement. In other cases it may result in other changes that also avoid competition. If competition avoidance is achievable, each species will occupy an edge of the niche and will become more specialized to that area thus minimizing competition.
This phenomenon often results in the separation of species over time as they become more specialized to their edge of the niche, called niche differentiation. The species do not have to be in separate habitats however to avoid niche overlap. Some species adapt regionally to utilizing different resources than they ordinarily would in order to avoid competition. There have been several well-documented cases in birds where species that are very similar change their habitat use where they overlap.
For example, they may consume different food resources or use different nesting habitat or materials.
On the Galapagos Islandsfinch species have been observed to change dietary specializations in just a few generations in order to utilize limited resources and minimize competition.
