Ecological Niche


In the field of biological sciences, the place occupied by a species or a group of them in a given ecosystem is called an ecological niche, in addition to this it also refers to the function that a specimen has within the community in which it operates, However, it is not only limited to that, since it can also be defined as the place where diversity of species coexist, where various factors such as anthropogenic, biotic and abiotic intervene.

The ecological niche of an individual can vary depending on the ecosystem where it lives, the function it fulfills in said place and the way in which the other species that make up the niche influence it. The function that the species fulfill in a given ecosystem is totally unique and different from what another species can fulfill, all this despite the fact that there are similarities of ecosystems where there could be the case of several species that fulfill the same function but perhaps with a different impact. If this is the case where two species play the same role, over time a phenomenon known as interspecific competition will occur, which represents a race to determine who will be the species that dominates and ends up eradicating its competence.

This can influence the ecosystem in different ways, since a certain population of species may vary according to the abundance of its resources and the number of predators it has in that region, since, for example, when the quantity of resources is abundant and predators are minimal, there will surely be an increase in the quantity of this species, directly affecting the very elements that allow its reproduction, since the resources that previously existed in abundance will surely be depleted.

On the other hand, in ecology, it is called the construction of the ecological niche, a change in the habitat or the direct variability of a species, due to a living organism. This process of changing the environment usually has completely different specific objectives for the organism itself, such as caring for the young, managing resources in the area, among others. In nature, the clearest example of this can be seen when beavers build their dams or when spiders weave their webs.
