Definition

noun, plural: niches

(ecology) (1) The specific area where an organism inhabits.

Supplement

In ecology, the definition of niche has changed overtime. Joseph Grinnell in 1917 coined the term niche, which he used as largely equivalent to a species habitat. In 1927, Charles Sutherland Elton regarded niche to be equivalent to the position of a species in a trophic web. In 1958, George Evelyn Hutchinson used the term niche to describe the multi-dimensional space of resources available to and used by a species.


Word origin: From Old (and modern) French niche, from nichier ‘make a nest’ (modern nicher), from Latin nidus ‘nest’.
