0003944RheeThis award supports Dr. G-Yull Rhee, Laboratory of Environmental Biology, Wadsworth Center, New York State Department of Health, to conduct collaborative research withDr. Jongseol Kim of the University of Ulsan in Korea. The joint study will investigate cell death among phytoplankton species. Phytoplankton cell death is an important loss process that affects the productivity of aquatic ecosystems. While external factors such as herbivore grazing and viral infection are major causes of cell death, internally-driven physiological death may also play a significant role in phytoplankton mortality. If the physiological death rate varies with species, it will not only affect primary productivity, but also interspecies competition and succession. Since cell death is accompanied by the release of dissolved organic carbon, it can also divert photosynthetically-fixed carbon to the microbial loop. This project will combine the complementary expertise and facilities of the American and Korean laboratories to advance our mutual understanding of the problem.

0003944RHEETHIS奖支持纽约州卫生部Wadsworth Center环境生物学实验室G-Yull Rhee博士，以进行合作研究。韩国Ulsan大学的Jongseol Kim。 联合研究将研究浮游植物物种之间的细胞死亡。 浮游植物细胞死亡是一个重要的损失过程，会影响水生生态系统的生产力。 尽管外部因素（例如草食动物放牧和病毒感染）是细胞死亡的主要原因，但内部驱动的生理死亡也可能在浮游植物死亡率中起重要作用。 如果生理死亡率随物种而变化，则不仅会影响主要生产力，而且会影响种间竞争和继承。 由于细胞死亡伴随着溶解的有机碳的释放，因此它还可以将光合固定的碳转移到微生物环上。该项目将结合美国和韩国实验室的互补专业知识和设施，以提高我们对问题的相互了解。
