Twenty-one species of cyclostome bryozoans are described from the coast of Qingdao (South Yellow Sea, China), belonging to 11 genera (Filicrisia, Crisia, Tubulipora, Exidmonea, Idmidronea, Qingdaoella n. gen., Nevianipora, Hemipustulopora, Microeciella, Patinella and Disporella). One genus (Qingdaoella n. gen.) and 10 species are new, while an additional species is reported for the first time from China. The most similar bryozoan assemblages to the Chinese cyclostomes described here are reported from the Sea of Japan and the western Pacific.

The identity of the pilumnid crab, Pilumnus dofleini Balss, 1933, is reassessed based on the female holotype and additional male specimens from Sagami Bay and the Sea of Japan, Japan. Three new species allied to P. dofleini are described and illustrated: P. curvipenis n. sp. from the Izu Islands, Japan; and P. armatus n. sp. and P. bohol n. sp. from the Bohol Sea, the Philippines. These four species are diagnosed, compared and differentiated from the related P. acanthosoma Ng, 2000.

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.

<p>Northeast China—located near the northern limit of the influence by the East Asian summer monsoon—receives most moisture through the westerly airflow, but variations in moisture contributions from the Yellow Sea in the western Pacific Ocean determine its hydroclimate during summer monsoon season. The proportion of moisture from the Yellow Sea is strongly modulated by the location and intensity of the Western Pacific Subtropical High (WPSH). However, it is still unclear how sensitive regional hydroclimate to WPSH-modulated change in moisture sources and its impact on peatland carbon accumulation. Here, we used macrofossil data and paired δ<sup>13</sup>C and δ<sup>18</sup>O isotope analysis of Sphagnum moss cellulose from a well-dated bog from a steep mountain slope in the Greater Khingan Mountains (~47˚N) to reconstruct peatland moisture changes and elucidate past shifts in moisture sources. δ<sup>13</sup>C values reflect peatland surface moisture, as dry conditions with less water film effects would increase isotopic discrimination against <sup>13</sup>C and result in lower δ<sup>13</sup>C values. Our results from a 250-year peat record show a decrease of ~3‰ in δ<sup>13</sup>C from -25 to -28‰—with corresponding increase in dry-adapted moss Polytrichum—suggesting a drying trend since about 1980 AD. Also, the down-core δ<sup>18</sup>O and δ<sup>13</sup>C data show a positive correlation (r = 0.65, p < 0.001), in contrast with evaporative enrichment of δ<sup>18</sup>O being the dominant effect. We argue that δ<sup>18</sup>O values reflect the input of moisture derived from the Yellow Sea—that has higher δ<sup>18</sup>O values than that from the westerlies—as modulated by the WPSH. When the WPSH extends westward, it blocks moisture transport from the Yellow Sea to North China, causing low δ<sup>18</sup>O values in summer precipitation, dry conditions, and negative shifts in δ<sup>13</sup>C, and vice versa. Furthermore, carbon accumulation rates show a major decrease after the 1980s—despite that more recent peat tends to have higher apparent accumulation rates—suggesting a sensitive response of this steep-slope mountain peatland to shift in regional hydroclimate in monsoon-margin region of Northeast China.</p>

AbstractActumnus simplex Rathbun, 1911, described 100 years ago and never reported again since, is recorded for the first time from the Persian Gulf. The species is characterized by a prominently convex dorsal carapace surface, regions that are weakly defined, four serrated anterolateral teeth, and a gently serrated frontal margin with a distinct median notch. It is morphologically close to Neoactumnus convexus Sakai, 1965, and N. unispina Garth & Kim, 1983, both from the western Pacific, but is easily distinguishable by possessing a distinct median notch in the frontal margin.
