| 1 | Identification of coastal water quality by multivariate statistical techniques in two typical bays of northern Zhejiang Province,East China Sea显示文摘The Hangzhou Bay(HZB) and Xiangshan Bay(XSB), in northern Zhejiang Province and connect to the East China Sea(ECS) were considerably affected by the consequence of water quality degradation. In this study, we analyzed physical and biogeochemical properties of water quality via multivariate statistical techniques. Hierarchical cluster analysis(HCA) grouped HZB and XSB into two subareas of different pollution sources based on similar physical and biogeochemical properties. Principal component analysis(PCA) identified three latent pollution sources in HZB and XSB respectively and emphasized the importance of terrestrial inputs, coastal industries as well as natural processes in determining the water quality of the two bays. Therefore, proper measurement for the protection of aquatic ecoenvironment in HZB and XSB were of great urgency. | YE Ran LIU Lian WANG Qiong YE Xiansen CAO Wei HE Qinyan CAI Yanhong | 2017 | Acta Oceanologica Sinica2017，36，2： | 4 |
| 2 | A new long-acting GLP-1 derivative KTP ameliorates hyperglycemia and dyslipidemia and improves pancreas and fatty liver in db/db mice显示文摘Glucagon-like peptide-1 (GLP-1) is a polypeptide incretin hormone that glucose-dependently promotes the secretion and synthesis of insulin. However, its half-life is extremely short. To enhance its half-life, we developed a long-acting GLP-1 derivative KTP with controlled release, designed on the basis of another GLP-1 derivative GP62. The kinetics and bioactivity of KTP were evaluated in Sprague Dawley (SD) rats. Long-term treatment of KTP was performed in db/db mice. Mice were treated twice daily with subcutaneous injections of KTP (1.2 mg/kg body weight), Exendin-4 (0.1 mg/kg body weight) or vehicle (phosphate buffered saline (PBS), pH 7.4) for 60 d. KTP had a longer half-life, as well as further increasing the secretion and production of insulin and reducing blood glucose concentrations, than GP62. Long-term treatment with KTP also induced anorexia, decreased water and food intake, decreased weight gain, improved blood glucose and blood lipid and ameliorated pancreatic damage and fatty liver in db/db mice. | SANG YanXia ZHOU TianHong LI HongJian RAN YanHong JIANG DeQi ZHENG Fei CHEN Ying WANG CongFeng ZOU Xin | 2013 | Chinese Science Bulletin2013，58，20： | 2 |
| 3 | The biogeographical distribution of tree species-abundance and its relation to climatic factors in mass islands显示文摘Tree species-abundance in forests is a function of geographical area and climate, although it is not clear whether such relationships apply to mass islands. We examined the spatial pattern of tree species in mass islands along the coast of Zhejiang, East China Sea using the Preston model, to identify the relationships between tree communities and climatic conditions. The results show that:(1) the biogeographical distribution of tree species-abundance conformes to Preston's log-normal pattern, and is in accordance with the findings in both tropical rainforests and estuarine forests;(2) the climatic factors related to tree communities in mass islands are similar to that of the subtropical zone, including the major species of evergreen needle-leaf, broad-leaf and deciduous broad-leaf forests. We conclude that the Preston model can be applied to the trees of mass islands and thus facilitate the systematic ecological researches of vegetation species' composition in subtropical zone. | LI Xiaoming WU Chengzhen GU Wu YE Ran ZHANG Haibo QI Ping WANG Shengqiang ZHOU Siying WEI Yongjie CAI Yanhong | 2017 | Acta Oceanologica Sinica2017，36，9： | 1 |

| 6 | Phytoplanktonic biogeography in the subtropical coastal waters,East China Sea along intensive anthropogenic stresses: roles of environmental versus spatial factors显示文摘Understanding the relative roles of local environmental effects and spatial effects on phytoplankton community is of essential importance to study the biogeography of them at regional scale. However, the determinants that driving the biogeography of phytoplankton communities in the coastal area of northern Zhejiang still remained unclear. We surveyed phytoplankton community compositions in water columns associated with environmental and spatial influences across five subzones that geographically covering this region over four seasons. Diatoms and dinoflagellates were recorded as the main dominant groups and Coscinodiscus oculs-iridis, Coscinodiscus jonesianus, and Skeletonema costatum, were identified as the major abundant species existing in all seasons.Spatially structured environmental conditions, rather than pure spatial or environmental factors, substantially shaped the biogeography of phytoplankton community, with the former mainly comprised of water temperature,dissolved oxygen, phosphate, pH, and salinity, and the latter referring to a non-negligible factor. This study was the first integrated research that combining environmental filtering with spatial factors in structuring phytoplankton communities at a complete tempo-spatial scale. Our results may facilitate to the further study of harmful algal blooms early-warning in this region. | Ran Ye Haibo Zhang Yige Yu Qing Xu Dandi Shen Min Ren Lian Liu Yanhong Cai | 2023 | Acta Oceanologica Sinica2023，42，4： | 0 |
| 7 | Ecological thresholds of phytoplankton community across environmental gradients in the harmful algal blooms-frequently-occurring,subtropical coastal waters,East China Sea显示文摘Phytoplankton communities can response immediately and directly to environmental changes,and thus have been applied as reliable biotic indicators in aquatic systems.This study provided insights into the relationships concerning ecological thresholds of phytoplankton communities and individual taxon in response to environmental changes in coastal waters of northern Zhejiang Province,East China Sea.Results demonstrated that there existed seasonal variations of phytoplankton community ecological thresholds of which spring being higher than those in summer.As for individual species,Prorocentrum donghaiense and Noctiluca scintillans were identified as the most tolerant and sensitive indicator species in spring and summer,respectively.They exhibited strong indications in response to environmental changes.These findings highlighted that phytoplankton community structure in this region was stable when environmental gradients were below the thresholds of sensitive species,whereas potential harmful algal blooms may occur when environmental gradients exceeded the thresholds of tolerant species. | Ran Ye Chunying Ge Qiong Wang Qing Xu Guofeng Xu Yongkang Yan Mingli Qin Yanhong Cai Yuejun Fei | 2021 | Acta Oceanologica Sinica2021，40，6： | 0 |
