Objectives: I explore and analyze diversity and evolution of species and communities of arthropods, especially scavenging beetles in forest leaf-litter, and faunal  assemblages on geographic islands and in habitat islands such as caves.  Islands and caves are chosen as frequently repeated natural experiments in replicating "simple" communities. Approach:  I use extensive field work to gather data on the presence of arthropod species, and their life cycles, habitat preferences, behaviour, ecology, etc. The approach provides a taxonomic data-base, and is aimed at testing and supplementing general ecological and evolutionary theory as well as generating and testing new hypotheses of species and community origin and organization.  Laboratory and museum study prepares systematic reviews and revisions to document patterns of biodiversity (including biochemical methods).   Significance: The work contributes to baseline documentation of arthropod diversity in forest-litter, caves, and islands.  Arthropods are life's most diverse phylum, and I contend that we know the least about arthropods on a per-species basis.  Generalities on patterns and processes in ecology and evolution will be further strengthened with data and tests from arthropods.  My work preserves samples of vanishing tropical arthropod biodiversity, and gives a standard for measuring disturbance impact, as in the Galapagos Islands.  Since 1989, my work there has added some 900 insect species (50% of the total) to the known fauna of the islands through innovative sampling methodologies.  Lastly, the research involves and supports students at all levels, and contributes to their training to meet further scientific manpower needs.  Student projects often have an applied or conservation orientation.

目的：我探索和分析的物种和节肢动物群落的多样性和演变，特别是在森林落叶层拾荒甲虫，和地理岛屿和栖息地岛屿，如caves.Islands和洞穴的动物群组合被选为经常重复的自然实验复制“简单”的社区。方法：我使用广泛的实地工作来收集节肢动物物种存在的数据，以及它们的生命周期，栖息地偏好，行为，生态等。这种方法提供了一个分类数据库，实验室和博物馆的研究旨在检验和补充一般的生态学和进化理论，以及产生和检验物种和群落起源和组织的新假设。实验室和博物馆的研究准备系统的评论和修订记录生物多样性的模式（包括生物化学方法）。 重要性：这项工作有助于森林凋落物、洞穴和岛屿中节肢动物多样性的基线记录。节肢动物是生命中最多样化的门，我认为我们对每种节肢动物的了解最少。节肢动物的数据和测试将进一步加强生态学和进化中的模式和过程的普遍性。我的工作保存了正在消失的热带节肢动物多样性的样本，并给出了一个衡量干扰影响的标准，比如在加拉帕戈斯群岛。自1989年以来，我在那里的工作增加了大约900种昆虫（占总数的50%）通过创新的采样方法对岛屿的已知动物群进行研究。最后，研究涉及并支持各级学生，并有助于他们的培训，以满足进一步的科学人力需求。学生的项目往往有一个应用或保护的方向。
