Diogenes Nitidimanus

A redescription of adult and larval stages of diogenid hermit crab Diogenes nitidimanus Terao, 1913 is presented. Morphological similarities suggest that D. nitidimanus is allied to D. avarus Heller, 1865, D. granulatus Miers, 1880, D. ovatus Miers, 1881, D. pugilator (Roux, 1838) and D. rectimanus Miers, 1884. Diogenes nitidimanus can be distinguished from the latter four species by different armature or ornamentation of the left chela and/or the shape of the ambulatory dactyli. Zoeal and megalopal stages of this species are described from laboratory-reared material hatched from parental individuals collected from Peter the Great Bay, Russian Far East. Larval development in the Russian population is compared with that described for a population of this species from southern Japan. The developmental morphology between the two populations is generally similar, but some minor differences, which might be attributable to variability, are found. Larvae of D. nitidimanus are morphologically closest to those of D. avarus among eight species of Diogenes for which larval descriptions are available.

The larval development of the hermit crabAreopaguristes nigroapiculus(Komai, 2009) (Decapoda: Anomura: Diogenidae) is described and illustrated from the material reared in the laboratory. The development included three zoeal and a single megalopal stages. At 22–25°C, megalop ofA. nigroapiculuswas attained 6–9 days after hatching. The present paper is the first description of the complete larval development in the genusAreopaguristes. Morphological characters of zoeas and megalop ofA. nigroapiculusare compared with those described for the closely relatedPaguristesspecies. The comparison on the zoeal characters revealed thatA. nigroapiculusis distinguished fromPaguristesspecies by the absence of anterolateral carapace spines and by the fused fourth telson process in zoea III. These two features are possible generic characters ofAreopaguristes. In the rest of larval characters,A. nigroapiculusagree well withPaguristesspecies having three zoeal stages. In the plankton of Peter the Great Bay, the larvae ofA. nigroapiculussporadically occurred only in July and August, at depths of 3–45 m and surface water temperatures of 18–22°C.

One of the most northern representatives of the family Atyidae, an amphidromous shrimp Paratya borealis Volk, 1938 (Crustacea: Decapoda: Atyidae), is considered as a junior synonym of Paratya compressa (De Haan, 1844 [in De Haan, 1833-1850]) based on morphological and genetic investigations of the specimens collected in rivers flowing into Peter the Great Bay and Posyeta Bay along the Russian coasts of the Sea of Japan. The study greatly increases the area of distribution of P. compressa to north for more than 1000 km and suggests that the species probably inhabit rivers flowing into the Sea of Japan also along North and South Korean coasts.

Two territories on the western coast of Peter the Great Bay were mapped in the large scale. The geobotanical mapping means revealing and displaying the essential regularities of vegetation cover. Both the spatial and temporal regularities of vegetation under natural and anthropogenic influences are well pronounced in the territory under consideration. The concept of the vegetation spatial unit (vegetation complexes) was applied as a basis for mapping. The maps and their legend were worked out as a system of vegetation combination types (vegetation combination is a spatial unit of the supracoenotic level). Such categories, as vegetation of tops and slopes, lowlands and river valleys, sea coasts reflect maximal contrasts in vegetation cover, so they are the highest level divisions of the map legend. Types of succession series and stages of series are developed for construction of the second and third levels of the legend. Communities, similar in ecotope, total species composition, saplings and some other characteristics, are referred to one type of series. 5 types of series have been distinguished: dry, fresh, moist, very moist, wet. The main factor of dynamics in considered territory is fire and the series are mainly pyrogeneous. Series are presented as sequences of vegetation stages. The vegetation stages for tops and slopes are: closed low forest — open low woodland — shrub thicket with saplings — meadow with saplings, for lowlands and river valleys they are: open low woodland — thicket of saplings — meadow or mire with saplings.

The sublittoral hermit crab Pagurus trigonocheirus (Stimpson, 1858) (Crustacea: Decapoda: Paguridae) is recorded from depths of 80–200 m along the continental coastline of the Peter the Great Bay, Sea of Japan. The exact sampling localities as well as photographs of live specimens are presented in the paper. Doubtful records of hermit crabs from the southern Russian coastline of the Sea of Japan are also discussed.

Littoral Fauna

Aim. The littoral fauna of the Far East Marine Reserve was studied at the end of the last century; however, the monitoring studies of the malacofauna are relevant because of the increased recreational load and the threat of new species introduction. The aim of the work is to update the data on species composition and distribution of gastropods and bivalves on the littoral zone of the reserve.Methods. The material was collected during the monitoring studies in 2012-2014. The compilation of the collections and identification of the species were carried out according to standard methods. For the definition, conventional determinants and atlases were used.Results. As a result of the research, 49 species and taxa of mollusks were found, including 33 gastropods and 15 species and 1 hybrid of bivalves. New for the littoral fauna of the reserve were 13 species of Gastropoda, 3 species and 1 hybrid Bivalvia. It was established that the introduction of Atlantic mussel Mytilus galloprovincialis into benthic communities occurs through its hybridization with native species.Conclusion. The data obtained allows us to present a more complete picture of the biodiversity and distribution of the littoral malacofauna of the reserve, an integral part of Peter the Great Bay.

Middle And Late Holocene

The results of biostratigraphic analysis of bottom sediments of the Karas’e, Utinoe, Krugloe lakes as well as loose sediments of accumulative plains at the mouths of the Tumannaya and Poima rivers in the south of the Far East are presented. Natural conditions were recovered and periodicity of vegetation changes in the foothills of the East Manchurian Mountains and in the coastal plains of the Peter the Great Bay in the Middle and Late Holocene were reconstructed by the complex of data. The synchronicity of both the development of vegetation formations and changes of sedimentation conditions with global climatic variations were revealed. The first, Middle Holocene stage proceeded in the conditions of general planetary increase of average annual temperatures, accompanied by flooding of lowland plains of the coast of the Sea of Japan by sea waters. The distribution and species diversity of broad-leaved plants in spurs of the East Manchurian Mountains increased. In the Holocene Optimum, the polydominant forests with richer composition of species than that of the present time were formed and vegetation on the foothill accumulative plains was represented with sedge and mixed meadows. The second, Late Holocene stage was characterized by a decrease in average annual temperatures and series of climatic changes. Its beginning was marked by the cooling, during which the coastal lowlands were freed from sea waters. Climate deterioration caused expansion of dark coniferous and small-leaved plants in the East Manchurian Mountains, as well as reduction of polydominant forests. On the foothills near the coast of the Peter the Great Bay sedge meadows were developed, sometimes there were thickets of shrubby birch (Betula sect. Nanae) and sphagnum swamps. At the end of the Late Holocene the warming occurred again. On the slopes of the East Manchurian Mountains, the vegetation formations with the dominance of Mongolian oak (Quercus mongolica Fisch. ex Ledeb.) and dentate oak (Quercus dentataThunb.), needle fir (Abies holophylla Maxim.), Korean pine (Pinus koraiensis Siеbold et Zucc.) and with the presence of birches began to dominate. The dissemination of pine (Pinus densiflora Siebold et Zucc.), elm (Ulmus sp.), hornbeam (Carpinus cordata Blume) and maple (Acer sp.) has increased. On the foothill lowlands the sedge-reed meadows with different grass dominated.
