0211186TrowbridgeThis three-year award for cooperative research on the invasive alga, Codium fragile ssp. Tomentosoides, involves field surveys and experiments at Lough Hyne, Ireland, the Channel Islands, the English Channel Coast and Atlantic French Coast. Cynthia D. Trowbridge of Oregon State University, Colin Little of Bristol University, William F. Farnham of University of Portsmouth, and Alan Critchley of Degussa, Texturan Systems Research Centre, will conduct research on ecological mechanisms inhibiting or facilitating invasion of Codium fragile. This macroalga is a widely distributed temperate seaweed that has spread across geographic regions and international boundaries.The investigators propose to conduct field surveys of invaded regions and field experiments testing causal mechanisms. They will document community attributes of the French and English shores to determine whether the invasive agla establishes itself primarily in disturbed communities. In the intertidal community of Lough Hyne, they will explore inhibiting and facilitating mechanisms, such as high cover of intertidal seaweed, high densities of fauna grazers, and low nutrient levels. The U.S. investigator brings to this collaboration expertise in the genus C. fragile and marine zoology. This is complemented by Dr. Farnham's expertise on introduced macroalgae, Dr. Critchley's expertise macroalgae biology, and Dr. Little's experience in intertidal communities. Insights into causes and conditions conducive to seaweed invasions could prevent future spread and impact coastal management practice.

0211186特罗布里奇这三年的合作研究奖的侵入性，松藻脆ssp。Tomentosoides，包括在海恩湖，爱尔兰，海峡群岛，英吉利海峡海岸和大西洋法国海岸的实地调查和实验。 辛西娅·D俄勒冈州州立大学的特罗布里奇，布里斯托大学的科林利特尔，威廉F。朴茨茅斯大学的法纳姆和德固赛组织系统研究中心的艾伦·克里奇利将对抑制或促进松藻入侵的生态机制进行研究。 这是一种广泛分布的温带海藻，已经跨越地理区域和国际边界。调查人员建议对入侵地区进行实地调查，并进行实地实验，以测试因果机制。 他们将记录法国和英国海岸的社区属性，以确定入侵的阿格拉是否主要在受干扰的社区建立自己。 在海恩湖的潮间带社区，他们将探索抑制和促进机制，如潮间带海藻的高覆盖率，动物食草动物的高密度和低营养水平。美国研究人员为这次合作带来了C属的专业知识。脆弱的海洋生态。 Farnham博士在引进大型藻类方面的专业知识、Critchley博士在大型藻类生物学方面的专业知识以及Little博士在潮间带社区方面的经验，都对这一点起到了补充作用。 深入了解有利于海藻入侵的原因和条件可以防止未来的传播和影响沿海管理实践。
