First Time

We report seven species of the genus Henricia Gray, 1840 that were found in Vostok Bay, and two species from adjacent area, known from museum collection or seen in underwater footage. while existing literature reported no confirmed species from this area. Most of these species: H. djakonovi, H. alexeyi, H. densispina, H. hayashii, H. granulifera, H. pacifica, H. asiatica, and H. oculata robusta were reported from the Sea of Japan previously. H. nipponica, known from Japan, is reported from Russian seas for the first time. All studied taxa are re-described here using a range of morphological characters and partial 16S rRNA nucleotide sequences, life colorations of several species are reported for the first time, and an identification key is provided. Lectotype designations are fixed for studied series of species described by AM Djakonov.

Проведены химико-экологические и микробиологические исследования современного состояния поверхностных прибрежных вод зал. Восток (Японское море). Наиболее напряженная экологическая ситуация отмечена в бухте Гайдамак, в районах у Волчанецкой протоки и устья р. Литовка. Протока, а также приустьевая зона р.Литовка являются главными тревожными участками в морском заказнике Залив Восток . The current state of the Vostok Bay water area (the Sea of Japan) is estimated using hydrochemical and microbiological indicators. The most intense environmental situation was noted for Gaydamak Bight, the area near the Volchanets duct and the mouth of the Litovka River. The duct, as well as the mouth of the Litovka River, are the main alarming sites in the Vostok Bay marine reserve.

First Time

An overlapping (postvolcanic) ore mineralization of volcanic rocks building up submarine edifices in the Sea of Japan has been semi-quantitatively and qualitatively evaluated for the first time. The study considers the main types of volcanic rocks (marginal continental, post-rift, and alkali ones) and focuses primarily on mineral phases formed in them by nonferrous, noble, and rare metals. The most enriched are post-rift rocks. That is due to the initial magma’s fluid saturation, as well as long-lived volcanic and postvolcanic processes.

Alpheid Shrimp

The originally poorly described alpheid shrimp Betaeus levifrons Vinogradov, 1950 is redescribed based on several adult specimens collected in the Vostok Bay (part of Peter the Great Bay) situated near Nakhodka City, about 90 km southwest from the type locality of the species, the Zolotoi Rog Bay, the Sea of Japan. The specimens were collected with the yabby pump from burrows on sandy-gravel bottom and appears to be associated with the burrowing mud-shrimps Upogebia major (De Haan, 1841) and U. issaeffi (Balss, 1914) (Upogebiidae).

The 16S Rrna Gene

An aerobic, Gram-stain-negative, saffron-pigmented, non-motile bacterial strain KMM 9545T, was isolated from a marine sand sediment sample obtained from the Sea of Japan seashore and characterized in a taxonomic study using a polyphasic approach. The 16S rRNA gene sequence of strain KMM 9545T showed a high level of similarity to species of the genus Gaetbulibacter (95.1–96.2 %), the type strains of species of the genus Tamlana (94.9–96.1 %) and members of the genus Algibacter (94.8–96.1 %). Phylogenetic analysis based on the 16S rRNA gene sequences positioned strain KMM 9545T as a distinct lineage in the cluster comprising species of the genus Tamlana . Strain KMM 9545T grew at temperatures between 5–36 °C and in the presence of 2–4 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C15 : 1, iso-C17 : 1 3-OH, iso-C15 : 0 3-OH and iso-C15 : 0 2-OH as the major fatty acids. The genomic DNA G+C content was 31.3 mol%. On the basis of the phenotypic characteristics and phylogenetic distance, it can be concluded that strain KMM 9545T represents a novel species of the genus Tamlana , for which the name Tamlana sedimentorum sp. nov. is proposed. The type strain is KMM 9545T ( = NRIC 0921T = JCM 19808T).

The larval shell morphology of 10 bivalve species of the family Mytilidae (Adula falcatoides, Crenella decussata, Crenomytilus grayanus, Modiolus kurilensis, Musculista senhousia, Mytilus coruscus, Mytilus galloprovincialis, Mytilus trossulus and Septifer keenae, and an unidentified species Mytilidae indeterminate) from the Sea of Japan is described. The following morphological features were comparatively examined: larval shell outlines including shape and size of umbones, and anterior, posterior and ventral margins, hinge morphology, ligament location, sculpture, colour, and eye-spot outlines. Some dimensional parameters of larval shells are given. The time interval of occurrence of larvae in the plankton, water temperature in this period, and shell length of competent larvae are presented. It is demonstrated that, in spite of sometimes similar external morphological characters, identification of mytilid larvae creates no difficulties if all distinguishing characters are used.

Four solitary ascidians are recorded in the deep-water material from the Sea of Japan. Two species, Agnezia orthenteronand Pelonaia bursaria are recorded for the first time since original descriptions, a third species, Styela squamosa, is awidely distributed deep-water species not known previously from the Sea of Japan. A fourth species was identified only to a genus level.

На основании обширного материала впервые проведена корреляция нижнесреднепалеозойских стратиграфических подразделений местного ранга различных регионов Япономорской зоны перехода континент–океан. Выделены стратифицирующиеся и нестратифицирующиеся магматические комплексы этих возрастов, представляющие собой вулканические, субвулканические, вулканоплутонические и плутонические образования. Авторами детально рассмотрены территориально разрозненные в основном палеонтологически охарактеризованные разрезы ордовика, силура и девона данного региона. В структурах, наложенных на докембрийские массивы, рассматриваемые отложения обычно хорошо прослеживаются по латерали, в то время как в полициклических подвижных поясах они залегают часто в виде олистолитов в мезозойских микститах или крупных ксенолитов в разновозрастных гранитоидах. Субмаринные ордовикские, силурийские и девонские отложения ЯЗ накапливались в сходной палеогеографической обстановке практически в одних и тех же седиментационных бассейнах, которые соединялись с центральноазиатскими, приохотскими и австралийскими морями. Континентальные осадки исследованной территории представлены девонскими толщами, включающими многочисленные растительные остатки, широко распространенными также в Центральном Казахстане, Западной Сибири, Приохотье и Южном Китае. On the basis of extensive material the correlation of Lower – Middle Paleozoic local-rank stratigraphic divisions of the Sea of Japan Continent – Ocean Transitional Zone is carried out for the first time. The stratified and non-stratified magmatic complexes of these ages, representing volcanic, subvolcanic, volcano-plutonic and plutonic generations are allocated. The authors have considered territorially separate, generally paleontologically characterized Ordovician, Silurian and Devonian sections of the given region in details. In the structures superimposed on Precambrian Massifs, considered sediments are usually well traced along the strike, while in Polycyclic Mobile Belts they lie down often in the form of olistoliths in Mesozoic mixtites or – large xenoliths in uneven-aged granitoids. Submarine Ordovician, Silurian and Devonian sediments of JZ accumulated in similar paleogeographic conditions, practically in the same sediment basins, which incorporated to the Central-Asian, Okhotsk and Australian Seas. Continental deposits of the investigated territory are presented by the Devonian strata, including the numerous vegetative remnants, widespread as well in the Central Kazakhstan, Western Siberia, Okhotsk Region and in Southern China.
