| 1 | Community structure and spatial distribution of macrobenthos in the shelf area of the Bering Sea显示文摘Field investigations of marine macrobenthos were conducted at ten sites in the Bering Sea in July 2010. Altogether 90 species of macrobenthos belonging to 59 families and 78 genera were identified. Among them, 41 polychaetes, 16 mollusks, 23 crustaceans, three echinoderms, two cnidarians, one nemertean, one priapulid, two sipunculids, and one echiuran were identified. The average density and biomass of total macrobenthos were 984 ind./m2 and 1 207.1 g/m2 of wet weight, respectively. The predominant species in the study area were Scoloplos armiger, Eudorella pacifica, Ophiura sarsii, Heteromastus filiformis, Ennucula tenuis, and Harpiniopsis vadiculus by abundance, while the predominant species in this area was Echinarachnius parma by biomass. Hierarchical cluster analysis(Bray–Curtis similarity measure) revealed that two important benthic assemblages in the study area were Community A and Community B. Community A was stable and Community B was unstable, as shown by the Abundance/Biomass Comparisons(ABC) approach. The macrobenthic community structure in the shelf of the Bering Sea was characterized by its high abundance and biomass, high productivity but great heterogeneity. | WANG Jianjun HE Xuebao LIN Heshan LIN Junhui HUANG Yaqin ZHENG Chengxing ZHENG Fengwu LI Rongguan JIANG Jinxiang | 2014 | Acta Oceanologica Sinica2014，33，6： | 4 |
| 2 | Biodiversity and community structural characteristics of macrobenthos in the Chukchi Sea显示文摘Field sampling of the macrobenthos from 23 stations in the Chukchi Sea was conducted during the 4th CHINARE(Chinese National Arctic Research Expeditions, July–August, 2010). We identified a total of 140 species of macrozoobenthos belonging to nine phyla, which were dominated by polychaetes(66), crustaceans(30), and mollusks(25), followed by echinoderms(9) and others(ten others, including four cnidarians, one oligochaete, one sipuncula, one priapulida, two bryozoans, and one urochordata). The dominant species were Aphelochaeta pacifica, Heteromastus filiformis, Nephtys ciliata, Nephtys caeca, Scoletoma fragilis, Golfingia margaritacea, Nuculana pernula, Macoma calcarea, Ennucula tenuis, Macoma inquinata, Musculus discors, Echinarachnius parma, and Ophiura sarsii, so there were more cold-eurythermal boreal immigrants than truly Arctic species(endemics). The average density and biomass(mean ± SD across all stations) of the total macrozoobenthos were(916 ± 907) ind/m2 and(902.9 ± 1 227.7) g/m2(wet weight), respectively. Relatively high density and biomass were observed in the samples from the northeastern and southern Chukchi Sea. The spatial variation of benthic communities in the study sea area was relatively large; this spatial heterogeneity has led to high diversity and a patchy distribution pattern in the community structure. Compared to the 1st CHINARE( July–August, 1999), this investigation revealed different degrees of decreases in the average taxa numbers and the average density, abundance, and biodiversity in the area over the recent decade, which might be associated with global warming, human activities, and sea ice variations. | WANG Jianjun LIN Heshan HE Xuebao LIN Junhui HUANG Yaqin LI Rongguan ZHENG Chengxing ZHENG Fengwu JIANG Jinxiang | 2014 | Acta Oceanologica Sinica2014，33，6： | 3 |
| 3 | 皮肤脂肪随着年龄变化而丢失的天然免疫抗菌功能是由转化生长因子TGFβ介导的显示文摘文章简介当皮肤受到金黄色葡萄球菌(S.aureus)感染后,真皮成纤维细胞(dFBs)可应激分化为脂肪细胞,释放抗菌肽CAMP来抵御细菌感染。在此项研究中,研究人员发现新生儿皮肤富含高表达抗菌肽Camp的成脂性成纤维细胞和未成熟脂肪细胞。这些具有成脂分化和抗菌能力的真皮成纤维细胞在出生后随年龄增长逐渐下降,导致皮肤脂肪在老化后减少。 | 张凌娟 Stella Xiang Chen Christian F.Guerrero-Juarez Fengwu Li Yun Tong Yuqiong Liang Marc Liggins Xu Chen Hao Chen Min Li Tissa Hata Ye Zheng Maksim V.Plikus Richard L.Gallo | 2020 | 科学新闻2020，，2： | 1 |
| 4 | Mediomastus chinensis sp. nov., a new species of Capitellidae (Annelida: Polychaeta) from the southeast coast of China显示文摘Mediomastus is a common genus around the world,and Chinese specimens used to be identified as M.californiensis Hartman.In this study,118 Mediomastus specimens collected from four localities along the southeast coast of China were examined.They belonged to an unknown species.We treat them as a new species,described herein.The new species is characterized as follows:(1)chaetigers 1–9 biannulate with chaetal fascicles at midsegment,thereafter multiannulate with chaetal fascicles posterior to midsegment;(2)parapodial ridges on posterior abdomen;(3)possession of bilimbate capillary chaetae on chaetigers 1–4;(4)thoracic hooks with long,straight shaft,hood length about 3–5 times width;(5)abdominal hooks shorter,with developed shoulder and distinct constriction,markedly different from those in thorax;(6)unique staining pattern with methyl green.The present study indicated that Mediomastus species inhabiting Chinese waters might be misidentified as M.californiensis,and that Mediomastus chinensis sp.nov.is widely distributed along the southeast coast of China. | LIN Junhui WANG Jianjun ZHENG Fengwu | 2018 | Acta Oceanologica Sinica2018，37，10： | 1 |
