0651325WitmanThis proposal will develop a research and training program for graduate and undergraduate students focused on biodiversity and ecosystem functioning in the Galapagos Marine Reserve. Undergraduate students will be recruited nationally as well as from Brown University. Each year for three years two graduate students and one undergraduate student will spend seven weeks in Ecuador at the Galapagos Marine Reserve, under the supervision of Dr. Witman of Brown University and Stuart Banks of the Charles Darwin Research Station in Ecuador. Students will focus on 2 major questions using experimental and observational approaches. 1) Does the diversity of grazers affect productivity, a key ecosystem function? and 2) What is the relationship between taxonomic diversity and functional diversity for invertebrates and fishes across the GMR? The project will also include a complementary study of the effect of fish predation on sea urchins, to build an understanding of how trophic cascades influence biodiversity - ecosystem functioning relationships.

0651325 Witman该提案将为研究生和本科生制定一项研究和培训计划，重点是加拉帕戈斯海洋保护区的生物多样性和生态系统功能。 本科生将在全国范围内以及布朗大学招募。 三年来，每年两名研究生和一名本科生将在厄瓜多尔的加拉帕戈斯海洋保护区度过七周，由布朗大学的Witman博士和厄瓜多尔查尔斯达尔文研究站的Stuart Banks监督。 学生将使用实验和观察方法专注于2个主要问题。1)食草动物的多样性是否会影响生产力这一关键的生态系统功能？大湄公河次区域无脊椎动物和鱼类的分类多样性与功能多样性之间的关系是什么？ 该项目还将包括一项关于鱼类捕食海胆影响的补充研究，以了解营养级联如何影响生物多样性-生态系统功能关系。
