Three main types of water masses were present in the study area: surface polar, Atlantic, and transformed Atlantic. The content of mineral biogenic elements increased with depth. The concentration of chlorophyll a had low values (0.07–0.13 mg/m3). The abundance and biomass of prokaryotes varied from 286 000 to 675 000 cells/mL and from 2.7 to 11.7 mg C/m3, respectively. The composition of prokaryotic plankton was dominated by single small cells (more than 97% of the abundance and more than 68% of the biomass). The average cell volume was 0.034–0.096 μm3. The number of viruses varied from 724 000 to 3 920 000 particles/mL, and the biomass varied from 0.040 to 0.216 μg C/m3. Against the background of local maxima in the abundance of prokaryotic plankton in the 0–25 m layer, the highest concentrations of viruses were noted in the surface layer. In the latitudinal distribution (from south to north), an increase in the number of viruses and prokaryotes was revealed. A close relationship between their abundance and biomass with hydrological parameters and phosphate content was established; the role of certain water masses in the vertical distribution of microbes was insignificant. The relatively high abundance of viruses and prokaryotes indicated their significant activity during the polar night.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139589849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results from the study divulged the meiofaunal assemblage pattern. It is diversified with the presence of ten meiofaunal groups represented by Foraminifera, Tintinnida, Nematoda, Polychaeta, Copepoda, Kinorhyncha, Tanaidacea, Ostracoda, Acarina and Priapulida larvae. Meiofaunal abundance was observed to be low during the year 2018 (5646 ± 874 ind./10 cm2) compared with previous reports from adjacent fjord systems and the samples collected during the 2017 study (8826 ± 1501 ind./10 cm2). The decrease in meiofaunal assemblage in the fjord is associated with changes in environmental constraints and organic matter availability. The diminishing sea ice habitats in the Arctic waters are expected to have pronounced impacts on meiofaunal communities and their appearances in the coming future. In this regard, data gathered during the present study will form a baseline information on meiofaunal communities in the Krossfjorden system for understanding future changes in the benthic habitat and have important implications on predicting the direction of change with regard to meiobenthic productivity.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139590109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

M. japonica was the most abundant in the shallow areas of the bays, closed from the direct wave impact, where, at a depth of up to 4–5 m, the density of the mollusc reached 27 ind./m2, and the biomass was almost 4 kg/m2, which averaged 56% of the total macrozoobenthos biomass. With increasing depth and moving from the dead-end of the bay to the open sea, the abundance of M. japonica decreased by one or two orders of magnitude. Local settlements differed significantly in size and age composition, size-frequency distribution of molluscs, indicating the nature of the replenishment of the benthic population with juveniles, as well as the proportion of commercial size individuals, which ranged from 37 to 98%.

In this study, fragments of soft-bodied animals were obtained among trawled material from the bathyal zone in the Japan Trench, about 41.51° N, 144.13° E, at depths of 1987–2007 m during the cruise KH-22-8 of the R/V Hakuho-maru in October 2022.

The results of observations of killer whales hunting for different types of prey and the data from an analysis of the contents of their stomachs were summarized; the species affiliation of the prey was compared with the affiliation of predators to the R- or T-type based on a genetic analysis. It has been shown that killer whales of the Far Eastern seas of Russia have a pronounced foraging specialization, which correlates with the haplotype of the mitochondrial DNA control region. Killer whales with the NT1 and GAT haplotypes previously described for mammal-eating T-type killer whales from the northeast Pacific (also called Bigg’s killer whales) have been observed preying on marine mammals but not on fish. Killer whales with the SR haplotype, previously described for fish-eating R-type killer whales from the northeastern Pacific, preyed only on fish. Two new T-type killer whale haplotypes have been discovered; animals with these haplotypes have been observed preying on large baleen whales. The importance of traditions and social learning in the differentiation of ecological niches in cetaceans has been noted. The specialization to hunt certain prey transmitted from mother to calves allows killer whales of different ecotypes to avoid food competition and acquire morphological and behavioral adaptations that facilitate hunting for a particular type of prey.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139589996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To clarify the taxonomic status of the Pacific worms, we obtained the genetic characteristics of L. cirrata from Grøtsund Fjord, near Tromsø, one of the sites where Michael Sars collected worms to describe this species. The phylogenetic analysis of sequences of five gene fragments (mitochondrial COI and 16S rDNA, nuclear 18S rDNA and 28S rDNA, and Histone 3) showed significant difference between the Norwegian worms and worms from the north-western part of the Sea of Japan (Russia) earlier identified by morphology as L. cirrata. Common inhabitants of shallow waters in the Sea of Japan, these worms are assigned to the new species Laonice kasyanovi sp. nov. Both Northeast Atlantic and the Northwest Pacific populations exhibit high and overlapping variability of the diagnostic morphological characters of adults, and thus the two species can be considered as siblings. The distribution of these two species in the North Pacific remains uncertain and can only be elucidated by molecular data. Adults and one larva from the White Sea were also sequenced and found to be genetically identical to L. cirrata from Norway. The trochophores of L. cirrata are described and illustrated. They are characterized by two circles of large vesicles in the thick egg membrane and have been incorrectly referred to Aonides by previous authors.
