Laboratory of Evolutionary Morphology

Staff Gallery

Laboratory of evolutionary morphology exists as an independent scientific unit since 1965. It has been founded and headed by a known scientist, Lenin Prize laureate, member opf the Academy of Sciences Leopoldina, academician A.V. Ivanov. 20 years later, laboratory was headed by his favorite disciple Yu.V. Mamkaev, widely known specialist on morphology and taxonomy of flatworms. Since 2007, the laboratory is headed by O.V. Zaitseva, recognized specialist on evolutionary morphology of invertebrate nervous system. Laboratory performs complex comparative morphological studies of the organization of Anatomical, histological, and functional systems in representatives of different taxonomic groups of invertebrate animals, including cnidarians, lower bilateral animals Acoela, parasitic and free-living flatworms, nemertines, mollusks, annelids, bryozoans, ascidians, and some others. The circle of objects studied in the laboratory includes representatives of the mentioned animal groups from all the oceans of Earth, the Black Sea, arctic and Far Eastern seas, freshwater reservoirs of European Russia, Middle Asia, the Lake Baikal, terrestrial snails and slugs of European Russia, Crimea, and Caucasus. Laboratory obtains laboratory cultures of tropical mollusks. The main part in studies is given to evolutionary and ontogenetic peculiarities of the formation and development of nervous system, receptor organs, and musculoskeletal system of animals. At present, the laboratory is virtually a single center of studies of evolutionary invertebrate neuromorphology in Russia.
