Genetic heterogeneity in euphausiid populations: Euphausia krohnii and Nematoscelis megalops in North Atlantic Slope Water1

Genetic heterogeneity of samples of Euphausia krohnii and Nematoscelis megalops collected from a 6,000‐km 2 area in western North Atlantic Slope Water was investigated by electrophoretic assay of allozymic variability at eight enzyme loci. Both species exhibited significant among‐sample heterogeneit...

Description
Summary:Genetic heterogeneity of samples of Euphausia krohnii and Nematoscelis megalops collected from a 6,000‐km 2 area in western North Atlantic Slope Water was investigated by electrophoretic assay of allozymic variability at eight enzyme loci. Both species exhibited significant among‐sample heterogeneity of allozyme frequencies. Genetic distances between samples were large for intraspecific comparisons ( D̄ = 0.116 for E. krohnii and D̄ = 0.203 for N. megalops ). This heterogeneity indicates that both species are genetically structured.
