Аннотация: The results of a study of the specific features of morphological and genetic polymorphism of the population of the anadromous White Sea common whitefish (Coregonus lavaretus L.) from the Keret' River are presented. As assessed by its morphological features, the whitefish population of the Keret' is homogenous. A comparison of the Keret' whitefish with whitefish populations of both Europe and Siberia revealed clear differences. These differences relate first and foremost to the fish locomotion and orientation in space: body depth, length and positions of fins, and interorbital width. The characteristics of skull features (craniological analysis) of the White Sea whitefish are presented for the first time. The results of an analysis of the polymorphism of the ND1 fragment of the mitochondrial DNA confirmed an earlier suggestion about the mixed origin of the Keret' River whitefish: the descendants of three different phylogenetic lineages were revealed in the population.

Vendace -- Morphological characters -- Allopatric origin -- Phylogenetic -- lineages -- Lake Pleshcheyevo
Аннотация: This is the report about the secondary contact zone of coregonids in the Upper Volga basin. Two mitochondrial DNA (mtDNA) phylogenetic lineages of vendace Coregonus albula (Linnaeus, 1758) living in Lake Pleshcheyevo have been analyzed and compared in terms of morphological characters. These lineages have developed under the conditions of allopatry and are characterized by strong differences of the mitochondrial DNA sequences. The lineages have coexisted in the same lake since the last glaciation maximum (about 10,000years ago). The morphological analysis has shown that representatives of both lineages correspond to C. albula, while slight, morphological variations between lineages indicate different food preferences and locomotor abilities. Scenarios where multiple distinct coexisting phylogenetic lineages are characterized by low levels of morpho-ecological divergence are uncommon. These situations are important for understanding biodiversity dynamics and the mechanisms that drive coexistence, adaptive divergence, hybridization, and extinction when genetically divergent lineages meet in secondary contact.

peregrine earthworm -- cryptic diversity -- morphology -- DNA-barcoding -- bioluminescence
Аннотация: The small synanthropic and peregrine earthworm Microscolex phosphoreus (Duges, 1837) is reported for the first time from Siberia. Morphological and DNA barcode (COI) analyses of this and widely separate samples worldwide demonstrate that, as currently identified, M. phosphoreus is a heterogeneous taxon, with divergent lineages occurring often in the same locality and hardly providing geographically structured genetic signals. The combined morphological and genetic evidence suggests that at least four of the found clades should be reclassified as separate species, both morphologically and genetically distinct from each other. However, as the specimen number was limited and only the COI gene was studied for the genetic work, we hesitate in formally describing new species. There would also be the problem of assigning the available names to specific lineages. Our findings encourage careful external and anatomical examination and using reliable characters such as the interchaetal distances and spermathecal morphology for correct identification and for deeper evaluation of cryptic diversity in this interesting bioluminescent worm.
