Below is a screen recording of an example of G. Evelyn Hutchinson’s visualization using three species: K, L, and M, plotting three factors on three axes (dimensions). The x-axis might define the range of temperatures tolerated by the species. Another dimension (y) might describe the depth range to which the species occurs. Prey size selection might be represented by another axis (z).
Hutchinson (1957) defined niche as an n-dimensional hypervolume (hyperspace). This represents the space of all environmental factors that affect the welfare of a species. Niche overlap can therefore potentially result in competition, niche differentiation allows species to coexist (Kaiser et al., 2011).
