Here is the context for Significantly of MacArthur’s later on operate, and Hutchinson generously cites MacArthur, in addition to Other individuals of his pupils.

The papers Within this part all address the problem: “The quantity of likely competitive species can be packed into a offered setting?” The papers kind an orderly sequence in complexity, subtlety, and energy: from raising aggressive effects that disfavor coexistence in Hutchinson and MacArthur 1959, to dividing discrete renewable methods by exploiting individual ratios of Those people sources in MacArthur and Levins 1964, to the same with continual and non-renewable means in MacArthur and Levins 1967, to including an explicit evolutionary element in MacArthur 1969, to an extension to other forms of Opposition in MacArthur 1970, and MacArthur 1972.
