It is named after G. Evelyn Hutchinson who concluded that various key attributes in species varied according to the ratio of 1:1.1 to 1:1.4.
In this paper this was strong evidence for niche differentiation for interspecific competition, and would also be a good argument for Hutchinson's rule.
And, therefore, it would be of particular interest to study the size differentiation of closely related species in different communities and reveal cases meeting Hutchinson's rule M.
[5] however, presents evidence that Hutchinson's constant is an artifact of the distribution of the size of animate, as well as inanimate, objects in nature.
They argue that the size ratio Hutchinson suggests doesn't tell a lot about the actual structuring of animal communities.
