This morphological and genetic study is
performed on several types of amphipods from
coastal waters compared to species outside the
Romanian Black Sea basin. The evaluation and
interpretation of morphological characters
highlighted that the group of romanian amphipod
genera (Euxinia, Pontogammarus,
Compactogammarus, Obesogammarus) are
probably evolving. The separation of more
primitive forms such as Echinogammarus and
Dikerogammarus is confirmed by some aspects of
molecular genetics analysis. |
