Arthropod Biodiversity in a Lowland Tropical Rainforest II

9401069石头作为热带研究组织和哥斯达黎加国家生物多样性研究所之间正在进行的合作项目的第二阶段，将在位于哥斯达黎加大西洋低地的生物丰富和科学活跃的生物站La Selva加强和扩大热带雨林节肢动物(蠕虫、蜘蛛和昆虫)的动物群清单。在项目第一阶段，在美国国家科学基金会的支持下，建立了设备齐全的专用节肢动物实验室、采集设施和数据管理系统，以及在这种支持下接受过广泛培训的ALAS准分类学家和生物多样性技术员的才能，将允许在第二阶段立即有效地利用物质和人力资源。随着两种新的重点分类群的增加，清单的范围将得到扩大：(1)在第一阶段建立的更广泛的调查分类群中的那些，因为已经进行了许多收集并已经准备了标本，(2)不在第一阶段调查分类群中的新的焦点分类群，但增加了扩大该项目的生态和系统发育范围。第二阶段新材料的收集和准备将转向项目工作人员和相关合作者一次为一个重点分类群(或一组相关的重点分类群)进行的一系列集中努力，使用生态结构的量化努力收集战略和适用于每个分类群的所有技术。25名系统学家P.I.S及其合作者(包括来自哥斯达黎加机构的7名合作者)将在第二阶段为名录工作做出贡献，同时用La Selva形式的材料丰富他们自己的系统发育和生物地理研究。标本将被纳入INBIO已经在进行的国家生物多样性清单，从而将La Selva调查材料置于更大的地理和系统背景下，促进INBIO不断扩大的国际专家网络S对这一材料的进一步研究，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合作途径。将继续探索和评价估计节肢动物区系丰富度和组成的方法，使用分类单元比率(等级和组间)、物种积累曲线以及丰度模式的参数和非参数分析。在第一阶段为该项目成功开发和实施的数据库应用程序的设计和功能将进一步完善和扩大，该应用程序将提供给其他项目，作为基于经验的想法的来源和工作工具。综上所述，这些活动应有助于进一步将该项目定位为其他多分类生物多样性清单的示范和方法评估试点，以及本身具有开创性和重大意义的清单。

9401069 Stone As the second phase of an ongoing collaborative project between the Organization for Tropical Studies and the Instituto Nacional de Biodiversidad (INBio, Costa Rica), a faunal inventory of tropical rainforest arthropods (mites, spiders, and insects) will be intensified and broadened at La Selva, a biotically rich and scientifically active biological station situated in the Atlantic lowlands of Costa Rica. A full-equipped, dedicated arthropod laboratory, collections facility, and data management system created with previous NSF support in Phase 1 of the project, and the talents of the ALAS Parataxonomists and Biodiversity Technician, who were extensively trained with that support, will allow immediate and efficient use of physical and human resources in Phase 2. The scope of the inventory will be expanded with the addition of two kinds of new focal Taxa: (1) those within the broader Survey Taxa established in Phase 1, for with many collections have been made and specimens already prepared, and (2) new Focal Taxa not within Phase 1 Survey Taxa, but added to enlarge the ecological and phylogenetic scope of the project. Collection and preparation of new material in Phase 2 will shift to a series of concentrated efforts, by the project staff and relevant collaborators, for one Focal Taxon (or set of related Focal Taxa) at a time, using an ecologically-structured, quantified-effort collection strategy and all techniques appropriate for each taxon. Twenty-five systematists P.I.'s and Collaborators (including 7 Collaborators from Costa Rican institutions) will contribute to work of the inventory in Phase 2, while enriching their own phylogenetic and biogeographical studies with material form La Selva. 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 systematic context, promoting further study of this material by INBio's growing international network of specialist s, and ensuring permanent accessibility of the specimens. The project is structured to promote extensive avenues of collaboration between North American and Costa Rican scientists. Exploration and evaluation of methods for estimating arthropod faunal richness and composition will continue, through the use of taxon ratios (both hierarchical and intergroup), species accumulation curves, and parametric and non-parametric analyses of abundance patterns. The design and functionality of the database application successfully developed and implemented in Phase 1 for the project will be further refined and expanded, and the application will be made available to other projects, both as a source of experience-based ideas and as a working tool. Taken together, these activities should serve to further position the project as a demonstration and methodological evaluation pilot for other multi-taxon biodiversity inventories, as well as a ground-breaking and significant inventory in its own right.
