Secure Slide Storage and a Frozen Tissue Component for the University of California Davis Nematode Collection (UCDNC)

加州大学戴维斯分校线虫收藏馆（UCDNC）是世界上最大、最全面的植物寄生、自由生活的土壤、淡水和海洋线虫收藏馆之一。模式幻灯片收集了11,000多个标本，包括代表930种和18个已确认目中的14个的3,454个主要类型。一般幻灯片收藏包括53,000多个标本，代表2221个物种和16个目。因此，该收藏保存了来自新物种描述的原始标本，与线虫学研究相关的代金券标本以及来自世界各地调查的标本。这些标本被研究线虫的科学家用于比较形态学、分类学、进化、生态学、生物防治和农业等方面的研究。高效的收集资源对线虫学研究至关重要，不仅因为线虫是最多样化和最丰富的多细胞生物群体之一，而且因为它们对人类活动（例如，植物寄生虫和农业，脊椎动物寄生虫和畜牧业，人类健康）具有重大影响。作为已鉴定标本的大型参考来源，UCDNC对线虫学相关研究的精确鉴定非常有用。该项目将提供一种新的玻片存储系统，以减少标本损坏的频率，促进玻片恶化的监测，并增加研究目的的标本获取。所采用的储存系统已被证明是非常有效的（在其他线虫收藏中），并且是确保标本长期保存的必要条件。

9709009 Nadler The University of Califomia Davis Nematode Collection (UCDNC) is known world-wide as having one of the largest and most comprehensive collections of plant parasitic, free-living soil, freshwater, and marine nematodes. The type slide collection includes more than 11,000 specimens, including 3,454 primary types representing 930 species and 14 of the 18 recognized orders. The general slide collection includes more than 53,000 specimens representing 2,221 species and 16 orders. Thus, the collection conserves original specimens from descriptions of new species, voucher specimens associated with nematology research, and specimens from surveys throughout the world. These specimens are used by scientists studying nematodes for research in comparative morphology, taxonomy, evolution, ecology, biological control, and agriculture. Efficient collection resources are essential for nematology research, not only because nematodes are among the most diverse and abundant multicellular groups of organisms, but because they have significant impact on human activities (e.g., plant parasites and agriculture, vertebrate parasites and animal husbandry, human health). As a large reference source of identified specimens, the UCDNC is extremely useful for precise identifications in nematology-related research. This project will provide a new system for storing slides to decrease the frequency of specimen damage, facilitate monitoring of slides for deterioration, and increase access to specimens for research purposes. The storage system to be employed has proved to be very efficient (in other nematode collections), and is necessary to ensure the long-term conservation of the specimens.
