AbstractThe concentrations of Fe, Mn, Cu, Zn, Pb, Cd, and Ni were studied in the brown algae Sargassum miyabei Yendo and S. pallidum (Turner) C. Agardh collected in Ussuri Bay, Sea of Japan, from 2001 to 2018. The degree of heavy metal pollution in different parts of the bay was assessed by comparing the actually measured concentrations of the meta...

AbstractThe effect of copper (10, 25 and 50 μg/L) on the population growth, physiological state, and ultrastructure of the microalga Heterosigma akashiwo (Raphidophyceae) were studied. Copper had a greater effect on the mitochondrial membrane potential than on chlorophyll a fluorescence. The neutral lipid content was lower in the exposed cell than ...

AbstractThe ability of fucoidans to scavenge reactive oxygen species still remains a subject of debate in scientific literature, as shown by an analysis of the results of recent studies on the antioxidant activity (AOA) of fucoidans. On the one hand, in vitro and in vivo experiments provide evidence that fucoidans of brown algae can modulate diseas...

AbstractIn this study, Acanthogyrus (Acanthosentis) persicus n. sp. is described from Periophthalmus waltoni Koumans, 1941 in Qeshm Island, Iran. P. waltoni is a species of oxudercine gobies, with a wide range of habitats including mangrove forests and tidal mudflats of the Persian Gulf. It is known as a biological indicator to monitor evolutionary...

AbstractThe values of the osmolality and the contents of sodium, potassium, as well as the contents of the total, free, and bound water fractions in blood serum, muscles, liver, and brain that are characteristic for fish in the sea and in rivers were determined for the far eastern big-scaled redfin, Tribolodon hakonensis. The osmolality associated ...

AbstractDescriptions of ten new and little-known species of macroalgae found during a revision of herbarium and live material collected by the authors from Peter the Great Bay, Sea of Japan, in 2001, 2018, and 2019 are provided in the present report. Of these, seven species are new to the Russian coast of the Sea of Japan, five species are new to t...

AbstractIn order to further understanding of how alga are adjusted to chromium(VI) toxicity at the level of photosynthesis, the pigment content and chlorophyll a (Chla) fluorescence parameters, were studied in Macrocystis pyrifera blades treated with 0, 0.5, 2, 10 and 20 mg/L Cr (VI) solution for 24 h. Results showed that these parameters were clea...

AbstractThe contents of total lipids and lipid fractions, the intensity of oxidative processes, and the antioxidant defense level in the blood, kidney, spleen, and liver of the Antarctic toothfish Dissostichus mawsoni (Actinopterygii: Nototheniidae) that inhabit stably cold Antarctic waters were studied depending on gender and age. This study revea...

AbstractA total of 137 strains of mesophilic and psychrotolerant hydrocarbon-oxidizing bacteria have been isolated from three regions of the Sea of Japan exposed to different levels of anthropogenic pollution. The taxonomic affiliations of the culturable bacteria from surface waters and bottom sediments that are involved in the biodegradation of pe...

AbstractThe limpet Lottia cf. borealis, a gastropod species widely distributed in the Far Eastern Seas of Russia, has been subjected to genetic analysis. Three genetic markers (COI, 16S, and 12S) showed no evidence of a distinct genetic structure of this species within the studied part of its range (the southern coast of Primorsky Krai and the coas...
