This chapter proposes a quantitative definition of niche that includes a species' requirements from and impacts on a factor. Requirements refer to the conditions where an organism's birth rates exceed its death rates on a particular factor, whereas impact refers to the effect that species has on the factor. The explicit recognition of both requirement and impact components of the niche provides a general framework for understanding the problems of species interaction and coexistence, which form the basis of much ecological inquiry.

Keywords: niche concept; species niche; birth rates; organisms; species interaction; coexistence
