This SGER proposal is an outgrowth of collaboration between Horn Point Laboratory,University of Maryland Center for Environmental Science and the University of Trieste andthe Laboratory for Marine Biology, Trieste, Italy. It is to support the participation ofDK Stoecker and a graduate student in an Italian expedition to the Ross Sea during theaustral summer 2002-2003. Techniques which have been recently developed to investigatethe autecology and population dynamics of temperate, coastal bloom-forming algae will beapplied to polar protists from the Ross Sea. This collaboration presents a tremendousopportunity to compare the role of microzooplankton grazing in bloom dynamics in temperateand polar systems, determine if polar microplankton have ectocellular protease activityand to obtain samples of the photosynthetic ciliate, Mesodinium rubrum and its crytophytealgal "prey" from the Ross Sea for molecular analysis. Futhermore, the cruise wouldcontribute to the education of a graduate student in polar science and provide materialfor his dissertation. It would also contribute to continued collaboration between UMCESand the Marine Biological Laboratory in Trieste, Italy.

该 SGER 提案是马里兰大学环境科学中心 Horn Point 实验室与意大利的里雅斯特大学和海洋生物学实验室合作的成果。这是为了支持 DK Stoecker 和一名研究生在 2002-2003 年澳大利亚夏季参加意大利罗斯海探险活动。最近开发的用于研究温带沿海水华形成藻类的自生态和种群动态的技术将应用于罗斯海的极地原生生物。这项合作提供了一个巨大的机会，可以比较微型浮游动物的放牧在温带和极地系统的水华动态中的作用，确定极地微型浮游生物是否具有胞外蛋白酶活性，并从罗斯海获取光合纤毛虫、红色中甲藻及其隐生藻类“猎物”的样本进行分子分析。此外，这次航行还将有助于极地科学研究生的教育，并为他的论文提供材料。它还将有助于 UMCES 与意大利的里雅斯特海洋生物实验室之间的持续合作。
