The maintenance of hybrid zones across a disturbance gradient.

abstract：:Twenty-eight spontaneous alterations modifying the hybridization banding pattern of six families of transposable elements (297, Foldback, copia, jockey, P and hobo) have been fixed in a set of mutation-accumulation lines of Drosophila melanogaster. Their effect on fitness has been studied by competition with the origi...
