9724759 CORNELL Professors Howard Cornell and Ronald Karlson of the Department of Biology at the University of Delaware, and Dr. Terence P. Hughes of the Department of Marine Biology of James Cook University, Australia, will sample corals in six sectors of increasing regional species richness across the Indo-West and Central Pacific Ocean to quantitatively evaluate the relative influence of regional and local processes on local richness. Data will be collected on species presence, relative abundance, habitat breadth, and depth range of selected species to test the effects of the increasing regional pool on local richness, evenness, habitat compression, and habitat overlap. This synthesis of regional and local perspectives should provide an integrated conceptual framework not only for basic studies of community ecology but also for applied problems associated with species extinctions, habitat loss and fragmentation, and ecological restoration.

[9724759]特拉华大学生物系的Howard CORNELL教授和Ronald Karlson教授，以及澳大利亚詹姆斯库克大学海洋生物系的Terence P. Hughes博士，将在印度洋-西太平洋和中太平洋的六个区域取样，以定量评估区域和局部过程对当地物种丰富度的相对影响。收集物种的存在、相对丰度、生境宽度和深度范围等数据，以测试区域池的增加对当地丰富度、均匀度、生境压缩和生境重叠的影响。这种区域和地方观点的综合应不仅为群落生态学的基础研究，而且为与物种灭绝、生境丧失和破碎化以及生态恢复有关的应用问题提供一个综合的概念框架。
