Long & Medium-Term Research: Population Ecology of Marine Specialist Herbivores on New Zealand Rocky Shores This award is under the Long and Medium-Term Research at Foreign Centers of Excellence Program, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a twelve-month postdoctoral research visit by Dr. Cynthia D. Trowbridge to visit Dr. Robert Creese at the University of Auckland, Leigh Marine Laboratory. Dr. Trowbridge proposed to study the population ecology of oligophagous ascoglossan sea slugs (Mollusca: Gastropoda: Opisthobranchia). She has already documented the population ecology of several species of intertidal ascoglossans in the N.E. Pacific. She now proposes to collect complementary information for three ecologically similar species in the Hauraki Gulf region of the North Island of New Zealand to address the following three questions. First, do ascoglossans seasonally reduce algal host abundances? Second, does interspecific competition among generalist and specialist herbivores reduce the effect of ascoglossan herbivory? Third, do fish and crab predators significantly reduce ascoglossan densities in the field? This study will provide valuable information about the role of marine specialists on temperate rocky shores. The award recommendation provides funds to cover international travel, a stipend for twelve months, and a dependent allowance.

长期中期研究：海洋生物种群生态学 新西兰岩石海岸上的食草动物 该奖项是根据长期和中期研究， 外国卓越中心计划，使美国 科学家和工程师将进行三到十二个月的 在国外经过验证的卓越研究中心进行研究。 的 该计划的奖项提供了联合研究的机会， 利用独特或互补的设施、专门知识和 国外的实验条件。 该奖项将支持为期十二个月的博士后研究访问 Cynthia D博士特罗布里奇去拜访罗伯特·克里斯博士 奥克兰大学利海洋实验室。 特罗布里奇博士提议研究 寡食子囊舌海蛞蝓（软体动物门：腹足纲： 后鳃类）。 她已经记录了 本文报道了东北部几种潮间带子囊藻的生态。 太平洋是如此 她现在建议收集补充信息 在豪拉基湾地区的三个生态相似的物种， 新西兰北岛，以解决以下三个问题 问题. 首先，子囊藻是否会季节性地减少藻类宿主 丰度？ 第二，种间竞争是否 多面手和专门的食草动物会降低Ascoglosan的作用 食草动物？ 第三，鱼蟹类捕食者是否显著减少 在田间的子囊菌密度？ 这项研究将提供有价值的 关于海洋专家在温带岩石 的海岸 该奖项的建议提供资金，以支付国际 旅费、12个月的津贴和家属津贴。
