Ecological Niche

The range of conditions and resources over which a species can continually exist. There are many often interrelated variable factors which influence an ecological niche, and it can be considered a multi-dimensional space of relationships (called an n-dimensional hypervolume).

The competitive ability of a species to successfully extract required resources within an environmental space will be a major driver in determining abundance of the species within a niche, along with its impact on co-existence with one or more other species.
