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

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
Zoogeographic subdivision of the north-western Sea of Japan based on species areas of pelagic nektonRussian Journal of Marine Biology - Tập 35 - Trang 87-96 - 2009
O. A. Ivanov
A new approach to biogeographical division was used to divide the north-western Sea of Japan into fragments with a uniform latitudinal zonal status of pelagic nekton species. This approach is based on computerized plotting of maps representing spatial distribution of continuous fields. Computer mapping of the study area was carried out in various time aspects: intradaily, interseasonal, and intera...... hiện toàn bộ
The Spatial Variability of the Fluorescent Characteristics of Phytoplankton in the Black SeaRussian Journal of Marine Biology - Tập 44 - Trang 1-7 - 2018
V. S. Tsilinsky, Z. Z. Finenko
The spatial variability of the photochemical efficiency of phytoplankton photosystem II was analyzed in two contrasting regions of the Black Sea: the western part of the deepwater region and a region influenced by the Danube River discharge. The fluorescence values for open (F0) and closed (Fm) photosystem II reaction centers in the investigated areas varied by an order of magnitude and correlated...... hiện toàn bộ
