As a collaborative project between the Organization for Tropical Studies (a consortium of 45 U.S. Costa Rican universities and museums) and the National Biodiversity Institute (INBio, a Costa Rican nongovernmental organization), a biodiversity inventory of tropical rainforest insects, spiders, and mites will initiated for La Selva, a biotically rich and scientifically active biological station situated in the Atlantic lowlands of Costa Rica. This stage of the project aims to produce full, species-level inventories for several focal groups of insects, spiders, and mites, including some of the most important groups in rainforest habitats. These inventories will be based on ecologically structured, repeatable sampling methods, as well as on less- structure supplemental collecting. A must broader range of survey groups, each including a focal group, will be inventoried using the structured sampling techniques alone. Statistical methods will be explored for estimating the total number of insect, spider, and mite species in the study areas, using the full inventory data for the groups to evaluate these methods and to calibrate estimates of species number for the broader survey groups. The sampling design will permit evaluation of the contributions of habitat would type vegetation structure species, and season to overall species richness. These estimated promise to provide the most realistic and comprehensive data yet available on the diversity of insect and spider species of tropical rainforests, and diversity estimates for any rainforest mite fauna. These groups or organisms, while representing well overall the species on earth, are still among the most poorly known. Specimens will be integrated into the national biodiversity inventory already underway at INBio, thus placing the La Selva survey material in a larger geographical and biological context, promoting further study of this material by INBio's growing international network of specialists, and ensuring permanent accessibility of the specimens. The project is structured to promote extensive new avenues of collaboration between North American and Costa Rican scientists.

作为热带研究组织（由 45 所美国哥斯达黎加大学和博物馆组成的联盟）和国家生物多样性研究所（哥斯达黎加非政府组织 INBio）之间的合作项目，将为位于大西洋的生物丰富且具有科学活性的生物站 La Selva 启动热带雨林昆虫、蜘蛛和螨虫的生物多样性清查 哥斯达黎加低地。 该项目的这一阶段旨在为昆虫、蜘蛛和螨虫的几个焦点类群（包括雨林栖息地中的一些最重要的类群）建立完整的物种级清单。 这些清单将基于生态结构、可重复的采样方法以及结构较少的补充收集。 将仅使用结构化抽样技术对范围更广的调查组（每个组包括一个焦点组）进行清查。 将探索统计方法来估计研究区域中昆虫、蜘蛛和螨虫物种的总数，使用各组的完整清单数据来评估这些方法并校准更广泛的调查组的物种数量估计值。 抽样设计将允许评估栖息地对植被结构物种和季节对总体物种丰富度的贡献。 这些估计有望提供有关热带雨林昆虫和蜘蛛物种多样性以及任何雨林螨类动物群多样性估计的最真实和最全面的数据。 这些群体或生物虽然很好地代表了地球上的物种，但仍然是最鲜为人知的。 标本将被纳入 INBio 正在进行的国家生物多样性清单中，从而将 La Selva 调查材料置于更大的地理和生物背景中，促进 INBio 不断扩大的国际专家网络对该材料的进一步研究，并确保标本的永久可获取性。 该项目旨在促进北美和哥斯达黎加科学家之间广泛的新合作途径。
