[5] Alteration of an ecological niche by its inhabitants is the topic of niche construction. [6] The majority of species exist in a standard ecological niche, sharing behaviors, adaptations, and functional traits similar to the other closely related species within the same broad taxonomic class, but there are exceptions.
The source–sink model of population dynamics has made contributions to many areas in ecology. For example, a species' niche was originally described as the environmental factors required by a species to carry out its life history, and a species was expected to be found only in areas that met these niche requirements. [18]
Ecomorphology, on the other hand, refers to those features which can be shown to derive from the ecology surrounding the species. In other words, functional morphology focuses heavily on the relationship between form and function whereas ecomorphology is interested in the form and the influences from which it arises.
Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of an organism from one habitat to another where it then experiences different environmental pressures.
A species' realized niche is usually much narrower than its fundamental niche width as it is forced to adjust its niche around the superior competing species. The physical area where a species lives, is its habitat. The set of environmental features essential to that species' survival, is its "niche." (Ecology. Begon, Harper, Townsend)
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...
Apparent competition can help shape a species' realized niche, or the area or resources the species can actually persist due to interspecific interactions. The effect on realized niches could be incredibly strong, especially when there is an absence of more traditional interference or exploitative competition.
Almost all species engage in ecosystem engineering, which occurs when the availability of a resource is altered by organisms that create, alter, or destroy habitats. [18] [19] Niche construction occurs when the interactions and relationship between a species and its environment alters the niche and selective pressure of the species. [8]
