In a very dense but remarkably rewarding argument, he develops analogs of Haldane’s and Fisher’s theorems through which carrying potential replaces reproductive charge because the responding variable (see also MacArthur 1971, cited underneath Bird Species’ Diversity). The quantitative benefits from the analogs correspond to Haldane’s end re
