Abstract

The evolutionary advantages of sexual dimorphism were theoretically investigated, using Volterra-like competition equations. A sufficient condition for the persistence of a dioecious species is an ecological partitioning of the habitat along sexual lines. If such specialization insures that the dioecious species is ecologically more efficient than its monoecious progenitor, then the dioecious type will prevail. Considerable ecological specialization is required to overcome an initial reproductive disadvantage, but, with the requisite specialization, a permanent reproductive deficit can be supported.
