Effects of photoperiod on daily activity rhythm of juvenile sea cucumber, Apostichopus japonicus (Selenka)Springer Science and Business Media LLC - Tập 29 - Trang 1015-1022 - 2011
Guancang Dong, Shuanglin Dong, Xiangli Tian, Fang Wang
In nature, Apostichopus japonicus exhibits a behavioral characteristic of emerging at night and sheltering during the day. Hence, it was commonly believed that longer and darker light conditions are better for a population of A. japonicus. In aquaculture situations therefore, animals have commonly been cultured without lighting, especially during juvenile-hatching culture. However, how the length ...... hiện toàn bộ
Inhibitor effects on the anodic behavior of iron electrodesSpringer Science and Business Media LLC - Tập 15 - Trang 156-162 - 2013
Wang Jia
Polarization and impedance measurements were used in this study on inhibitor effects on the anodic behavior of iron electrodes showing that the sharp Tafel slope decreases of the anodic polarization curves resulted from inhibitor desorption for iron electrodes in acidic solution containing some types of inhibitors. An electrochemical parameter, desorption potentialE

Antioxidation and ATPase activity in the gill of mud crab Scylla serrata under cold stressSpringer Science and Business Media LLC - - 2007
Xianghui Kong, Guizhong Wang, Shaojing Li
Mud crab (Scylla serrata) is an important commercial crustacean in China. An experiment was designed to study the effect of cold stress on S. serrata. After a one-week adaptation at 28°C, the temperature is suddenly reduced to 4°C. The crabs were sampled every 2 h for 10 h and dissected immediately to measure the enzyme activity. The crabs at room temperature (28°C) were used as the control group....... hiện toàn bộ
Development and evaluation of a DNA microarray assay for the simultaneous detection of nine harmful algal species in ship ballast and seaport watersSpringer Science and Business Media LLC - Tập 34 Số 1 - Trang 86-101 - 2016
Chen, Xianfeng, Zhou, Qianjin, Duan, Weijun, Zhou, Chengxu, Duan, Lijun, Zhang, Huili, Sun, Aili, Yan, Xiaojun, Chen, Jiong
Rapid, high-throughput and reliable methods are urgently required to accurately detect and monitor harmful algae, which are responsible for algal blooms, such as red and green tides. In this study, we successfully developed a multiplex PCR-based DNA microarray method capable of detecting nine harmful algal species simultaneously, namely Alexandrium tamarense, Gyrodinium instriatum, Heterosigma aka...... hiện toàn bộ
A dinoflagellate Cochlodinium geminatum bloom in the Zhujiang (Pearl) River estuary in autumn 2009Springer Science and Business Media LLC - Tập 30 - Trang 371-378 - 2011
Zhixin Ke, Liangmin Huang, Yehui Tan, Xingyu Song
A severe Cochlodinium geminatum red tide (>300 km2) was observed in the Zhujiang (Pearl) River estuary, South China Sea in autumn 2009. We evaluated the environmental conditions and phytoplankton community structure during the outbreak. The red tide water mass had significantly higher dissolved inorganic phosphate (DIP), ammonia, and temperature, but significantly lower nitrite, nitrate, dissolved...... hiện toàn bộ

Studies on Gelidium amansii agar fractionations were carried out in this paper. Gelidium amansii agar was fractionated on DEAE-Cellulose, and four fractions were obtained sequentially. The fractions were analyzed on physical and chemical properties, and IR and 13C-NMR spectroscopy applied for elucidating the chemical structure. Among the four fractions obtained, water fraction measured up to the s...... hiện toàn bộ
