Sympatric speciation was studied in two sister species of cottoid fish from Lake Baikal (East Siberia): big golomyanka or Big Baikal oilfish (Comephorus baicalensis Pallas, 1776) and small golomyanka or Little Baikal oilfish (C. dybowski Korotneff, 1905). Analysis of nucleotide sequences of mitochondrial cytochrome b gene showed that the Little Baikal(More)
Baikalian cyclopoids represent one of the richest endemic faunas of freshwater cyclopoid copepods. The genus Diacyclops Kiefer, 1927 is the most numerous by species number in the lake. In this work, molecular-phylogenetic analysis of 14 species and 1 sub-species from Lake Baikal and its water catchment basin is performed. The regions of mitochondrial(More)
The population structure of Epischura baicalensis Sars (Copepoda, Calanoida), one of the key endemic species of the plankton community of Lake Baikal was studied. An analysis of mitochondrial DNA polymorphism revealed no genetic differences between Epischura sampled in the different basins of the lake or in the winter-spring/summer generations. Baikal(More)
The value of chromatin diminution (CD) in different species of freshwater cyclopoid copepods can differ significantly. The biological and evolutionary roles of these differences remain unclear. To expand the knowledge on CD distribution and magnitude in this group of copepods, a quick method for its evaluation was required. This study proposes a simple(More)
The content of total lipids, total phospholipids, and fatty acids of total lipids in muscles and liver of juvenile Lake Baikal sympatric coregonid fishes have been analyzed for the first time under a common garden experiment. Baikal omul, Coregonus migratorius Georgi, is an active migrant of the pelagic zones of the lake. Baikal (lacustrine) whitefish, C.(More)

Intraspecific genetic polymorphism of a Baikal Lake endemic, little Baikal oilfish (Comephorus dybowski Korotneff, 1905), was evaluated based on microsatellite analysis. Six microsatellite loci designed for the European sculpin, Cottus gobio, were used. Each locus was tested using 25 to 32 individuals from each of the Baikal basins (southern, middle, and(More)
Structure and cytometric indices of red blood cells (RBC) and hemoglobin content (Hb) and oxygen capacity of the blood (OCB) of omul, whitefish, and hybrids thereof captured in Lake Baikal (wild) and incubated and grown in a freshwater aquarium complex (FAC) (farmed) have been analyzed. Cytometric parameters of red blood cells of wild omul, whitefish, and(More)
Lake Baikal is inhabited by a relatively large number of cyclopid species, many of which are endemics. Two genera, Diacyclops Kiefer, 1927 and Acanthocyclops Kiefer, 1927, are the most specious in the lake. Taxonomic discrimination of the majority of representatives of these genera is difficult owing to their high morphological similarities and poor(More)
