AbstractThe effect of exposure to acute hypoxia on the level of methemoglobin (MtHb) in blood and the activity of catalase (CAT) and superoxide dismutase (SOD) in erythrocytes of the Black Scorpionfish (Scorpaena porcus, Linnaeus 1758) was studied in experiments in vivo. The O2 concentration in seawater was reduced from 8.5–8.7 mgO2/L to the requir...

AbstractHemolymph is one of the main tissues providing invertebrates’ immunity and homeostasis. Earlier, we showed that some of the hemolymph immune parameters of the common Far Eastern mollusk Modiolus kurilensis are sensitive to bacterial and anthropogenic challenges. In this work, a number of cellular parameters such as total hemocyte count (THC...

AbstractTo assess the biodiversity of symbiotic dinoflagellates (SD) in hydrocorals, we compared the molecular species compositions of four SD lipid classes such as diacylglyceryl-3-O-carboxyhydroxymethylcholine (DGCC), digalactosyldiacylglycerol (DGDG), monogalactosyldiacylglycerol (MGDG), and sulfoquinovosyldiacylglycerol (SQDG) in Millepora dich...

AbstractThe white-edged rockfish Sebastes taczanowskii Steindachner, 1880 is a marine viviparous teleost, which plays a substantial role in the functioning of subtidal fish communities and is an important recreational fishery species [2]. The biology of S. taczanowskii has been well studied; however, there is no information about the population str...

AbstractThis article presents the results of studies of the cyanobacteria from foulings of natural and anthropogenic substrates of the intertidal zone of the Kola Bay of the Barents Sea for the period from 2010 to 2019. Ninety-five cyanobacterial species from 46 genera, 20 families, and 6 orders were found; 22 species are given for the first time f...

AbstractFive consecutive ichthyoplankton surveys were conducted during the spawning season of the walleye pollock Gadus chalcogrammus, in April and May 2019, at a spawning ground off the western coast of the Kamchatka Peninsula. Daily walleye pollock egg production was estimated for each survey based on the number of spawned eggs recorded. The tota...

AbstractThe study of diatoms (Bacillariophyta) collected in 2000–2001 with a plankton net from the hypersaline Kara-Bogaz-Gol Bay revealed 13 species and varieties of the genera Campylodiscus, Cocconeis, Diploneis, Epithemia, Navicula, Nitzschia, Planothidium, Surirella, and Tryblionella. These diatoms occurred at water salinities from 44 to 250‰. ...

AbstractThe effects of polyphenolic impurities on the biological activity of fucoidan samples from the brown alga Fucus distichus subsp. evanescens were studied using the model of developing embryos of the sea urchin Strongylocentrotus intermedius. The embryotoxic action of fucophloretol from F. evanescens (IC50 = 96.90 ± 12.20 μmol/L) and cucumari...

AbstractThe problem of the coexistence of closely related species of Paguroidea (Decapoda: Anomura) and the main mechanisms of structuring the communities of these species in sympatry are discussed: differential use of habitats, competition for resources, and physiological resistance to abiotic factors. It is thought that the competition for gastro...
