    主 講:David Hutchins, Professor of Marine and Environmental Biology, University of Southern California

    地 點:周隆泉樓A3-206

        由高坤山教授邀請的,來自南加州大學的David Hutchins教授于20157-9月訪問廈門大學,并將于716日做學術報告,詳情如下:

    Abstract:

    The Hutchins lab works on how phytoplankton communities and the marine biogeochemistry of carbon, nutrients and trace metals may be affected by future environmental change.  One current project is using experimental evolution techniques to examine the effects of long-term selection by high CO2 on the physiology, gene expression and protein expression of a key player in the ocean nitrogen cycle, the N2-fixing cyanobacterium Trichodesmium.  This cyanobacterium adapts to high CO2 in a manner that is completely unprecedented in the microbial evolution literature, and does so based on a set of surprising and unexpected mechanisms.  These results will be discussed in light of their implications for marine microbial evolution and the biogeochemical cycles of a rapidly changing ocean.
