Niche   Ecology ]

Dictionary of botanic terminology - index of names

Synonym: Ecological niche, Environmental niche.
  The unique environment or set of ecological conditions in which a specific plant or animal species occurs, and the function the organism serves within that ecosystem.  
In a general meaning, a niche is a special place within the scheme of things. It sometimes denotes the function or position of a thing within a structure.
In ecology a niche is the role of an organism within its environment and community (affecting its survival as a species), the ecological opportunities it exploits and its adaptive response to that environment. Includes nutrition, where it lives, when itís active and its interaction with other living things.
Practically a niche is the physical and functional "address" of an organism within an ecosystem (the special area with special conditions that supplies a species with factors necessary for its survival) or the life style of an organism, where a living thing is found and what it does there.

Each organism has a specific role (or job) referred to as its niche, and two species are not expected to share the same exact niche for long.
