MacArthur was additional serious about competition than in predator-prey and ecosystem dynamics, though he made a few contributions into the latter. He argued that, less than plausible assumptions, biotic assemblages would are likely towards a gradual-state composition in their parts, variously: for age distributions in just a populace in MacArthur 1958, for species inside a trophic level or simply a Group in MacArthur 1958 and MacArthur 1960a, and for species or functional units within just an ecosystem in MacArthur 1955. MacArthur 1955 was a very important initiator with the discussion concerning the relation between range and balance; the paper has frequently been misconstrued as proving that range conveys steadiness, but it is cited admiringly and handled effectively by Rooney and McCann 2012.
