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 CommunityRussian 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
Description of a New Quadrigyrid Species from Periophthalmus waltoni Koumans, 1941 in IranRussian 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
The Use of the Mortality Rate of Marine Fish Prelarvae for the Estimation of Zinc and Lead ToxicityRussian 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 HepatitisRussian 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
