A genetic and morphometric comparison of Helisoma trivolvis and Gambusia holbrooki from clean and contaminated habitats.

Ecotoxicology and environmental safety - 1 Oct 1994

Benton M J, Diamond S A, Guttman S I

Abstract excerpt

Genetic and morphometric data from freshwater snail (Helisoma trivolvis) and mosquitofish (Gambusia holbrooki) populations from a relatively clean and a severely contaminated habitat were compared. Within the clean habitat, snail genetic patterns may have been more influenced than those of mosquitofish by site-specific selection because of the lesser likelihood of gene flow among snail subpopulations. Distinct...
