Collaborative Research: Global Survey and Inventory of SolifugaePaula E. Cushing & Lorenzo Prendini co-PIsSolifugae are the sixth most diverse order of arachnids in number of families, genera, and species, yet their evolutionary relationships and diversity are largely unknown. New species continue to be discovered. The objectives of this project are: 1) to conduct fieldwork in four regions of greatest solifuge diversity to discover new species, document their distributions, and gather fresh material for morphological, anatomical, behavioral, and genetic studies; 2) reconstruct the evolutionary relationships and revise the higher classification of the order; 3) establish international collaborations and provide resources for solifuge specialists currently working in isolation; 4) train new specialists; and 5) disseminate knowledge about solifuges to the public through scientific publications, seminars, and the internet. Solifugae are the dominant insect predators in arid ecosystems on all major terrestrial landmasses except Antarctica, Australia, Madagascar, and New Zealand, and form important prey for vertebrates in such habitats. They are indicators for desert environments, their disappearance signaling habitat degradation. Those studied in any detail appear to be habitat-specific and range-restricted, exacerbating their risk of extinction due to human activities, yet they receive no formal protection. Many species may disappear before being described. The activities planned in this project, including training of new taxonomic specialists, will enhance scientific infrastructure and will vastly improve our understanding of these poorly known arachnids.

合作研究：全球避日植物调查与编目。库欣Lorenzo Prendini co-PIsSolifugae是第六个最多样化的蛛形纲动物的家庭，属和种的数量，但他们的进化关系和多样性在很大程度上是未知的。新物种不断被发现。本计画的主要目的是：1）在四个避土目最具多样性的地区进行野外调查，以发现新的物种，记录其分布，并收集形态、解剖、行为和遗传学研究的新材料; 2）重建该目的演化关系，并修订该目的高级分类; 3）建立国际合作，为目前孤立工作的避日专家提供资源; 4）培训新的专家;（五）通过科学出版物、研讨会和互联网向公众传播避日剂知识。在除南极洲、澳大利亚、马达加斯加和新西兰以外的所有主要陆地上的干旱生态系统中，避日虫是主要的昆虫捕食者，并在这些生境中形成脊椎动物的重要猎物。它们是沙漠环境的指标，它们的消失标志着栖息地的退化。任何详细的研究似乎都是特定于栖息地和范围有限的，加剧了它们因人类活动而灭绝的风险，但它们没有得到正式的保护。许多物种可能在被描述之前就消失了。该项目计划的活动，包括培训新的分类专家，将加强科学基础设施，并将大大提高我们对这些鲜为人知的蛛形纲动物的了解。
