Interannual Variability in Bioluminescence Field Intensity in Nearshore Waters of the Black SeaInland Water Biology - Tập 11 - Trang 286-291 - 2018
E. B. Melnikova
This paper analyzes interannual variations in the bioluminescence field intensity in nearshore relatively deep outside waters and in an enclosed shallow-water bay from 2009 to 2014; it presents analytical expressions of the interannual trends and reveals the 1.4- to 2.7-time decrease in the interannual bioluminescence field intensity over the studied period.
Diatom Algae (Bacillariophyta) in Rock Pools on Islands and Shore of the Kandalaksha Gulf, White SeaInland Water Biology - Tập 14 - Trang 241-246 - 2021
S. I. Genkal, N. V. Vekhov
A total of 131 taxa of species and intraspecies rank of diatom algae from 41 genera have been identified during a scanning electron microscopy study of material from several rock pools on islands and the shore of the Kandalaksha Gulf in the White Sea. Among them, one species (Cymbopleura cf. angustata var. fontinalis Krammer) is new for the flora of Russia; 16 forms from 12 genera are identified o...... hiện toàn bộ

The content of total free nucleotides (TFNs) in the plankton of the Rybinsk reservoir and in specific size fractions of the plankton has been determined by the spectrophotometric method modified by the authors. The content of TFNs amounts to 58.1 ± 5.4, 75.2 ± 4.6, and 64.1 ± 7.3 μg/L in spring, summer, and autumn, respectively, and exhibits a close correlation with the total plankton biomass (r =...... hiện toàn bộ
New Representative of the Genus Aulacoseira (Bacillariophyta) from Chukotka (Russia)Inland Water Biology - Tập 16 - Trang 136-138 - 2023
S. I. Genkal
A new species of diatoms, Aulacoseira chukotkaensis sp. nov., is described using scanning electron microscopy. The new species is morphologically similar to other species of the genus. It differs from A. alpigena by the number of rows of areolae (per 10 µm) and the length and shape of the spines, from A. helvetica by the valve height and number of rows of areolae (per 10 µm), and from A. pardata b...... hiện toàn bộ
