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)

A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which potential ...
A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1]An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system.
In a Dominance preemption model of niche apportionment the species colonize random portion between 50 and 100% of the smallest remaining niche, making this model stochastic in nature. A closely related model, the Geometric Series, [ 9 ] is a deterministic version of the Dominance pre-emption model, wherein the percentage of remaining niche ...
A vacant niche or empty niche is an ecological niche in a particular ecosystem that is not occupied by a particular species. The issue of what exactly defines a vacant niche and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they ...
The Eltonian niche is an ecological niche that emphasizes the functional attributes of animals and their corresponding trophic position. This was the definition Eugene Odum popularized in his analogy of the niche of a species with its profession in the ecosystem as opposed to the habitat being its address.
Specialized applications of outlines also exist. A reverse outline is a list of sentences or topics that is created from an existing work, as a revision tool; it may show the gaps in the document's coverage so that they may be filled, and may help in rearranging sentences or topics to improve the structure and flow of the work.
