Abstract: | Isoelectric focusing was used to study total protein patterns and allozyme variations of six species of the genus Calanus. Each species could be characterized by total protein patterns. The results of the allozyme study indicated, in agreement with previous morphological studies, that the six Calanus species belong to three different groups: the C. finmarchicus group C. finmarchicus, C. glacialis and C. marshallae the C. helgolandicus group (C. helgolandicus, C. pacificus), and C. hyperboreus, which stands apart. There is no indication that there are more loci coding for the proteins studied in species with larger genome sizes. Nor is the degree of enzyme polymorphism related to genome size in these species. |
