Clines Induced by Variable Selection and Migration.
Abstract
The problem studied is in the area of differential equations; it models the spatial distribution of the genetic composition of a population in a heterogeneous environment, account being taken of migration and natural selection effects. More generally, it models a distribution in the composition of an ecological community. A number of conditions are given which guarantee the existence or nonexistence of a stable nonuniform equilibrium distribution, which is known as a cline. Of special interest is the case when two stable homogeneous distributions are possible; there may or may not also exist a heterogeneous one. (Author)
