Our recent work found Indonesian throughflow (ITF) have three major branches: the flow through the Makassar Strait; through the South China Sea; and through the eastern Indonesian basins.The results reveal that the Makassar Strait and the eastern Indonesian basins throughflow displays strong interannual variation.Inspection of depth integrated dynamic height within the eastern basins suggests that this interannual variation can be traced to the New Guinea Coastal Current,indicative of a strong influence of the South Pacific.The depth integrated dynamic height along the south Java coast is related to variation in the North Pacific as well as in the Indian Ocean equatorial wave guide,and in particular near the east of Mindanao Island.Whereas the depth integrated dynamic height along the coast of West Australia is related to variation in the South Pacific,in particular near the coast of New Guinea.The integrated dynamic height difference between the Java and New Guinea coast appears to be a good proxy of ITF transport on the interannual time scale.Regression analysis shows a phase dependence of the three ITF pathways on the Nino3.4 index.Decoupling of current anomalies between the surface and subsurface layers is identified in the developing and mature phase of El Nino,reflecting different effects of local forcing and remote forcing through oceanic pathways at the Makassar Strait and the eastern Indonesian basins.

微生物之所以能形成生物膜是因为有胞外多聚物( extracellular polymeric substances,EPS)组成的基质网(matrix)将单个的细菌联合在一起.该基质网是如何形成,以及在生物膜发育过程中是否有相应的变化并不很清楚.在此报道中,我们以铜绿假单胞菌作为模式菌对该问题进行了探索性研究.利用与生物膜基质网关键多糖Psl 特异性结合的凝集素标记,我们观测了整个生物膜发育过程中

林分、林窗结构是森林生态学基础研究和森林经营实践的重要基础,因此,探索准确、快捷确定林分、林窗结构量化的方法并在森林经营中应用便成为森林可持续经营的关键之一.综观国内外关于森林结构研究历史和现状发现,林分结构的研究多集中于水平结构及带状防护林结构上,而关于林分垂直结构的研究则十分薄弱;另外,林窗作为森林演替中最重要的小尺度干扰,其结构的变化直接影响森林演替方向,而关于林窗结构研究则多为定性研究,不
