Abstract:
|
In 1953, Howard Levene wrote a short paper that was published as a letter to the editor of The American Naturalist. In it, he showed that if more than one ecological niche is available to a population and one allele is favored over another in some niches and is at a selective disadvantage elsewhere, it is possible to have a stable equilibrium with both alleles present in substantial proportions everywhere. This paper still appears in reference lists of publications in which ideas contained in it are elaborated and generalized. I shall discuss lines of research to which Levene's note has given rise.
