An electrophoretic study of the antarctic zooplankter Euphausia superba1

Genetic variability has been estimated for a large population of the antarctic krill, Euphausia superba, by gel electrophoresis. Of 36 loci studied, 21 (58.3%) exhibit allelic variation. An average individual is heterozygous at 5.8% of the loci, a moderately low level of variability when compared to...

Description
Summary:Genetic variability has been estimated for a large population of the antarctic krill, Euphausia superba, by gel electrophoresis. Of 36 loci studied, 21 (58.3%) exhibit allelic variation. An average individual is heterozygous at 5.8% of the loci, a moderately low level of variability when compared to benthic invertebrates. Low to moderately low genetic variabilities are previously recorded from benthic invertebrates in environments with highly seasonal trophic resources, and E. superba fits this relationship.
