AbstractAn endosymbiotic dinoflagellate isolated from the soft coral Stichodactyla haddoni from the coast of Hormuz Island, Strait of Hormuz, Persian Gulf, has been characterized morphologically for the first time. Spherical and egg-shaped cells 6–13 μm in diameter (8–13 μm during mitosis) were recorded. Transmission electron microscopy showed the ...

AbstractPoorly esterified pectin was isolated from the seagrass Phyllospadix iwatensis Makino, 1931 and modified using acidic hydrolysis in 0.5 M HCl. The concentration of anhydrogalacturonic acid, the degree of methoxylation, and the molecular weight distribution were determined in the native and hydrolyzed pectins. The sorption capacity of these ...

AbstractThis paper presents an analysis of the literature data on the Subantarctic fauna of the benthic Myodocopida, including 97 species. The studied fauna is characterized by a high degree but a low level of endemism. The fauna is based on the species of common genera. Ostracods of the families Cylindroleberididae and Cypridinidae lead in the num...

AbstractA method for estimating the integral microalgae biomass beneath a unit surface was designed based on a mathematical model for phytoplankton vital function in the water column and subsequently tested. The model was verified based on data collected during field studies. The results of remote sensing allow extending this method to cover large ...

AbstractThe status of the aggregation of the Pacific oyster Crassostrea gigas (Thunberg, 1793) in the Busse Lagoon (Sakhalin Island) was assessed in 2019. The uncontrolled harvesting of this bivalve species caused its abundance to decline. The total oyster stock in the lagoon is estimated at 24.1 t; the commercial stock is estimated at 3.8 t; the a...

AbstractThe reproduction, growth, and variability of the shape of the shell in the gastropod Boreotrophon candelabrum (Reeve, 1848) from Peter the Great Bay (Sea of Japan) were investigated. In aquarium conditions, the mollusks started to lay transparent hemispherical egg capsules in late April at a water temperature of 5.6°C. The females with a sh...

AbstractA brief overview on the history of systematics of the order Gigartinales (Rhodophyta) is provided. The changes in the taxonomy of algae of this order from the Far Eastern seas of Russia based on the molecular phylogenetic data are analyzed. Taxonomic problems that can only be resolved by modern methods are discussed.

AbstractThe benthic flora off the Luhuitou Peninsula (Sanya Bay) was studied, for the first time, in areas located opposite a wastewater outlet from fish farm ponds and, thus, heavily polluted with nutrients (dissolved organic nitrogen (DIN), on average 30 μM; orthophosphates, 5.0 μM). Changes in the benthic flora were recorded before and after the...

AbstractA number of polyphenol fractions were extracted from the brown alga Thalassiophyllum clathrus (Postels & Ruprecht, 1840) by the method of liquid–liquid extraction using solvents of increasing polarity, and their antioxidant activities were studied. The extract obtained with ethyl acetate was characterized by a maximum polyphenol content of ...
