| 1 | Modeling the contribution of the microbial carbon pump to carbon sequestration in the South China Sea显示文摘The two key mechanisms for biologically driven carbon sequestration in oceans are the biological pump(BP) and the microbial carbon pump(MCP); the latter is scarcely simulated and quantified in the China seas. In this study, we developed a coupled physical-ecosystem model with major MCP processes in the South China Sea(SCS). The model estimated a SCSaveraged MCP rate of 1.55 mg C m^(-2) d^(-1), with an MCP-to-BP ratio of 1:6.08 when considering the BP at a depth of 1000 m.Moreover, the ecosystem responses were projected in two representative global warming scenarios where the sea surface temperature increased by 2 and 4°C. The projection suggested a declined productivity associated with the increased near-surface stratification and decreased nutrient supply, which leads to a reduction in diatom biomass and consequently the suppression of the BP. However, the relative ratio of picophytoplankton increased, inducing a higher microbial activity and a nonlinear response of MCP to the increase in temperature. On average, the ratio of MCP-to-BP at a 1000-m depth increased to 1:5.95 with surface warming of 4°C, indicating the higher impact of MCP in future ocean carbon sequestration. | Wenfang LU Yawei LUO Xiaohai YAN Yuwu JIANG | 2018 | Science China Earth Sciences2018，61，11： | 4 |

| 4 | A Preliminary Study on Cold Tolerance in Cinnamomum japonicum Sieb. at Different Ages显示文摘[Objective]This study aimed to further expand the production and application of Cinnamomum japonicum Sieb.and investigate the mechanism of cold resistance in evergreen broad-leaved tree species.[Method]Using adult Cinnamonum campora as control,during the entire wintering period from October 2011 to March 2012,the wintering adaptability of C.japonicum leaves at different ages was observed;the electrolyte leakage was measured under indoor low-temperature treatment to calculate the semi-lethal temperature(LT50)by fitting Logistic equation,thus conducting dynamic analysis and comprehensive evaluation of the cold resistance in C.japonicum.[Result]The results showed that the chilling injuries in leaves of different materials were aggravated with the decreasing temperature.According to the results of five times of dynamic observation on wintering adaptability,the cold resistance in different materials presented a decreasing order of adult C.japonicum>medium-aged C.japonicum>young C.japonicum>adult C.campora.The relationship between indoor low temperature and leaf injury rate showed an S-shaped curve.The significance test suggested relatively high fitting degree with Logistic equation.The semi-lethal temperature presented a V-shaped curve with the changing temperature and reached the minimum during late December to early February in the following year.The dynamic changes and minimum value of semi-lethal temperature indicated a consistent order of cold resistance in different materials to the results of wintering adaptability observation.Therefore,results of two analysis methods could be combined for cold resistance evaluation.[Conclusion]This study laid the foundation for the introduction and popularization of C.japonicum in northern gardens along the Yangtze River. | Dongqin ZHOU Yuwu XIONG Zhiguo LU Luwan HAN Ziyang WANG Yunlong YIN | 2013 | Agricultural Biotechnology2013，2，6： | 0 |
