Abstract
Abstract Clonal plants, fungi, and invertebrate animals often display both intra- and interspecific heterochronic variation in the relative proportions of ramets (e.g., polyps, plantlets) and stolons (or rhizomes, hyphae). Treatment of developing colonies of Podocoryne carnea, a hydractiniid hydroid, with dilute solutions of 2,4-dinitrophenol (DNP), an uncoupler of oxidative phosphorylation, accelerates the usual ontogenetic trajectory of polyp and stolon production. This morphological heterochrony can be related to the hydrodynamic behavior of the gastrovascular system under the conditions of "loose-coupling" of oxidative phosphorylation produced by DNP. In its...
