对虾白斑综合症病毒核衣壳蛋白VP664的鉴定研究

对虾白斑综合症病毒核衣壳蛋白VP664是至今知道的分子量最大的结构蛋白，全长18234bp，预计编码6077个氨基酸．从编码vp664基因的两端各选600bp，分别命名为vp664n、vp664c进行原核表达，成功表达纯化了目的蛋白并制备抗体．蛋白印记杂交（Western blot）实验中蛋白特异抗体只与完整的病毒和核衣壳裂解蛋白中的VP664蛋白反应，而不和膜蛋白反应，证明VP664基因所编码的蛋白在完整病毒颗粒上定位于核衣壳．     

Geographic and bathymetric trends in abundance, biomass and body size of four grenadier fishes along the Iberian coast in the western Mediterranean

The present study is a mesoscale analysis of latitude and depth related trends in abundance, biomass and body size of the four grenadier species Caelorinchus caelorhincus, Hymenocephalus italicus, Nezumia aequalis and Trachyrinchus scabrus inhabiting the deep western Mediterranean. We have analysed data from seven annual bottom trawl surveys, carried out down to 800 m depth along the Iberian Mediterranean coast covering a distance of approximately 1200 km. The objectives were to establish general patterns in the mesoscale distribution of abundance, biomass and body size of deep-water grenadier fishes and also analyse the consistency of the bathymetric distribution of these parameters along a large latitudinal gradient. Five complementary series of analyses have been completed. The first focussed on describing the general patterns of abundance and size by correspondence canonical analysis, CCA, in the area. The second and third series focussed on the existence of temporal, geographical and bathymetric trends of abundance, weight and mean size by analysis of covariance, ANCOVA and multiple regression analysis. The fourth series compared the frequency distributions of body length. Finally, the last series focussed on the patterns of abundance versus size. The total number of individuals of all four grenadier species captured in 260 bottom trawls amounted to 27,435 and their weight was 1404 kg. No general trends for the four species have been observed between years. All four species showed a general pattern of increasing size with depth, which, except in the case of C. caelorhincus, was consistent along a large latitudinal gradient. Nezumia aequalis was unique in showing the same noticeable trend of increasing abundance with depth along the entire latitudinal range, but with clear differences in the intercepts. The abundance of N. aequalis and C. caelorhincus decreased significantly northwards. Hymenocephalus italicus was the least abundant species and had a homogeneous distribution without any specific trend along the entire latitudinal range analysed. The distribution of T. scabrus in the Mediterranean seemed to be more localised. Higher abundances were found to the north and south of the latitudinal gradient with lower values between. The grenadiers studied also showed a general trend of decreasing mean size northwards, except in the case of the smallest species, H. italicus. The relation between abundance and body size differed between sectors for the whole grenadier population and species-specific variations were also observed. The relationship between individual body mass and population density fit well to a second-order polynomial function rather than to a linear regression, showing a significant trend for density to increase with increasing size until some mid-point, then to decline with increasing size thereafter. The observed latitudinal gradient in the distribution patterns of grenadiers along the upper slope of the western Mediterranean can be discussed in relation to direct and indirect factors of biogeographic, environmental and anthropogenic origin.     

西菲律宾海晚第四纪沉积地球化学特征

对１９８８对取自西菲律宾海区的３个沉积物柱样进行系统的地球化学研究。结果表明，本区的沉积物属半远洋沉积物，其地球化学特征受控于陆源沉积作用、海洋生物沉积作用和海底火山常积作用。据主要化学元素和ＣａＣＯ５的柱状变化进行地层划分和古气候的恢复，区分出末次冰期的亚间冰期沉积、冰期最盛期沉积和全新世沉积。本区的ＣａＣＯ３变化表现出两种类型，ＷＰ１柱样属大西洋型溶解旋回；ＷＰ２和ＷＰ４０柱样属太平洋型溶解旋
