Analysis of the taxonomic position of most species and forms of the char (genus Salvelinus, Salmonidae: Teleostei) was made based on RAPD-PCR. The material was represented by samples from 29 populations from the Kuril Islands, coast of the Sea of Okhotsk, Kamchatka, Chukotka, Taymyr, Transbaikalia, the Kola Peninsula, Svalbard, Finland, and North America.(More)
The aim of the study is a comparative investigation of changes that certain genome parts undergo during speciation. The research was focused on divergence of coding and noncoding sequences in different groups of salmonid fishes of the Salmonidae (Salmo, Parasalmo, Oncorhynchus, and Salvelinus genera) and the Coregonidae families under different levels of(More)
Genetic resemblance of chars Salvelinus alpinus krasheninnikovi (Salvelinus malma krasheninnikovi) of 35 samples collected in five Kuril Islands—Shumshu, Paramushir, Onekotan, Iturup, and Kunashir—has been studied by the PCR-RAPD method. In the limits of each island, both resident isolates and anadromous forms give strictly supported clusters distinct from(More)
Walleye pollock Theragra chalcogramma Pallas occupies a central place in ecosystems of the North Pacific and is an important target species of fisheries. The species is characterized by daily vertical, spawning, feeding, and wintering migrations and spawning occurring under the sea ice. Since population structure estimation by the tagging with recapture is(More)
The phenetic variability (types of life strategy, age and sex structure of population, biological peculiarities), the anthropogenic pressure, and the genetic diversity were studied by five microsatellite loci for several minor populations of brown trout Salmo trutta inhabiting the waterbodies of Velikaya Salma Strait watershed area (Kandalaksha Bay, the(More)
A BLAST search of the markers used for Kuril Island Dolly Varden population structure studies revealed homologies of these markers either with structural genes or at least with expressed sequences from the dbEST resources of GeneBank. The nature of the markers allows one to suppose an adaptive character of their evolution.
The intraspecific structure of major populations of the walleye pollock Theragra chalcogramma from the northwestern part of the Bering Sea was studied. Specimens from Navarin, Olyutor and Shirshov shoals were sampled in the 2001 spawning season. Preliminary cluster analysis (TREECON) of PCR-RAPD data revealed the existence of cluster with low level of(More)
Although the functional role is still unknown for most types of nuclear noncoding repetitive sequences, some of them proved to provide adequate phylogenetic and taxonomic markers for studying the genetic relationships of organisms at the species and within-species levels. Several markers were used in this work. First, microsatellite markers were used to(More)
Taxonoprint (a modification of DNA restrictase analysis) allows to distinguish sympatric species, that do not mate or produce hybrid offspring that are sterile or not viable. It is shown that taxonoprints of whitefish are very similar of identical. Sympatric whitefish are continuing to be separate despite they easily mate in experiments and in nature (up to(More)
