Electrophoretic variation in proteins encoded by seven presumptive gene loci was analyzed in four populations of the stygobiont amphipod Niphargus rhenorhodanensis and it is suggested that either low migration rates or the presence of ecological barriers to gene flow may result in strong genetic differention among local populations of Niph argus.

The Bou-Rouch technique was used to sample two small alluvial plains in two different karst areas. One was mainly supplied by karst water (Verna), the other by both karst and surface water…
