Between several traditional statements of ecological theory, MacArthur indicates that successional convergence of the community with a “climax” affliction, if it exists, is an easy residence with the Local community dynamics being an ergodic Markov chain. His bibliography is eclectic but idiosyncratic.
The most effectively-acknowledged principle of frequency distribution MacArthur proposed from the late fifties is definitely the so-known as broken adhere product. This product were prompt by MacArthur as amongst a few competing products of frequency distribution. He proposed that competing species divide up available habitat in a random fashion and without overlap, like the segments of the damaged stick.
MacArthur 1960b implies the usage of reproductive value in scientific tests of predator-prey relations, even though the context of the suggestion seems additional theoretical than useful.

Hutchinson and MacArthur presume that the world an individual can examine is correlated with its size, and derive a log-usual distribution of animal sizes.
