Abstract

The ecological literature states that closely related species that occur in the same ecological area undergo competition until one out-competes the other (or until each becomes restricted to a very specific niche). Darwin (1859) stated that species of the same or related genera which had nearly the same structure and habits undergo severe competition. More recently this view has been restated in what is known as "Gause's Law" (Gause 1934; Gilbert, Reynoldson, and Hobart 1952). Bagenal (1951) emphasized the difficulties in determining what is meant by the same habitat or the same community. Actually, as Bagenal (Ibid.) pointed out, because of their relationships, related species are most likely to be found in similar habitats though not in identical ones.
