A Laboratory Study of the Effect of Temperature on the Embryonic Diapause of the Hermit Crab Pagurus proximus Komai, 2000 (Decapoda: Paguridae) from Peter the Great Bay, Sea of Japan
Russian Journal of Marine Biology - Tập 48 - Trang 231-237 - 2022
E. S. Kornienko
Under laboratory conditions, the effect of temperature on the reversible arrest in embryo development, which occurs as a result of winter spawning, was studied in the hermit crab Pagurus proximus, Komai, 2000 from Amurskiy Bay (Peter the Great Bay, Sea of Japan). In clutches of females that spawned under natural conditions at a water temperature of 5°C and below, an increase in water temperature t...... hiện toàn bộ
The composition and structural characteristics of polysaccharides of the brown alga Eisenia bicyclis
Russian Journal of Marine Biology - Tập 39 - Trang 208-213 - 2013
R. V. Men’shova, S. P. Ermakova, B. H. Um, T. N. Zvyagintseva
The present study examines the polysaccharide composition of the brown alga Eisenia bicyclis. The major polysaccharide of E. bicyclis is shown to be sodium alginate (15.8% of the dry defatted alga weight). The yields of laminaran and fucoidan were 1.4% and 1.3% of the dry defatted alga weight, respectively. The alga contains laminaran (1,3;1,6-β-D-glucan) that has a unique structure, a high conten...... hiện toàn bộ
On the Species Structure of a Competitive Marine Community
Russian Journal of Marine Biology - Tập 44 - Trang 159-163 - 2018
V. V. Sukhanov
Some examples of marine animal and plant communities with a structure determined by competitive inter-species relationships are discussed. It has been shown that the ranked species structure of these communities obeys a geometric progression, whose coefficient does not differ significantly from the constant exp(–1) = 0.368. A relationship between a certain parameter of this progression and the spe...... hiện toàn bộ
Bottom Communities of Nyivo Lagoon (Northeastern Sakhalin)
Russian Journal of Marine Biology - Tập 28 - Trang 225-234 - 2002
N. V. Pecheneva, V. S. Labai, A. I. Kafanov
Clasterization of benthic stations by biomass of common species using an index of coenotic similarities allowed us to distinguish three communities of macrophytobenthos (Zostera marina + Z. japonica, Zostera japonica, and Potamogeton pectinatus) and eight macrozoobenthos communities (Macoma balthica, Limnodrilus hoffmeisteri + Anisogammarus tiuschovi, Spio filicornis + Archaeomysis grebnitzkii, Ka...... hiện toàn bộ
Analysis of interpopulation and interspecies morphological differences between Far Eastern redfins of the genus Tribolodon (Teleostei: Cyprinidae)
Russian Journal of Marine Biology - Tập 42 Số 1 - Trang 1-10 - 2016

Description of a New Quadrigyrid Species from Periophthalmus waltoni Koumans, 1941 in Iran
Russian Journal of Marine Biology - Tập 47 - Trang 226-231 - 2021
Saeed Yaghfoori, Mehdi Ghanbarifardi, Fatemeh Bossaghzadeh
In 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 processes. A. (A.) persicus n. sp. is recognized by havin...... hiện toàn bộ
Perspectives of the conservation of the marine and coastal ecosystems in the frame of the realization of the Convention on Biological Diversity
Russian Journal of Marine Biology - Tập 32 Số S1 - Trang S45-S49 - 2006
V. N. Bocharnikov, А. Б. Мартыненко
The Use of the Mortality Rate of Marine Fish Prelarvae for the Estimation of Zinc and Lead Toxicity
Russian Journal of Marine Biology - Tập 30 - Trang 217-222 - 2004
S. A. Cherkashin, M. V. Nikiforov, V. A. Shelekhov
The effect of zinc on the prelarvae of the Japanese anchovy Engraulis japonicus and on the sand flounder Limanda punctatissima punctatissima and of lead on the prelarvae of the Japanese anchovy was investigated. The median lethal concentrations and maximum ineffective concentrations for a 96-h exposure were calculated. The maximum ineffective concentrations of metals did not exceed their backgroun...... hiện toàn bộ
The Influence of an Extract from the Marine Brown Alga Sargassum pallidum on the Metabolic Reactions in the Liver under Experimental Toxic Hepatitis
Russian Journal of Marine Biology - Tập 43 - Trang 479-484 - 2018
V. G. Sprygin, N. F. Kushnerova, S. E. Fomenko, E. S. Drugova, L. N. Lesnikova, V. Yu. Merzlyakov, T. V. Momot
This study explores the influence of an extract enriched with polyphenol substances obtained from the brown alga Sargassum pallidum and the effect of the Legalon commercial reference preparation on the biochemical indices of the blood at acute hepatic injury induced in rats with carbon tetrachloride (CTC). Administration of S. pallidum extract exhibited a pronounced antioxidant and hepatoprotectiv...... hiện toàn bộ
