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

9709009纳德勒加州大学戴维斯分校线虫标本馆（UCDNC）是世界上最大和最全面的植物寄生线虫、自由生活土壤线虫、淡水线虫和海洋线虫标本馆之一。模式标本馆收藏了超过11，000个标本，包括3，454个主要类型，代表930个物种和18个公认目中的14个。一般幻灯片收藏包括超过53，000个标本，代表2，221种和16目。因此，收藏保存了新物种描述的原始标本，与线虫学研究相关的凭证标本，以及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、生物控制和农业的研究。有效的收集资源对于线虫学研究是必不可少的，不仅因为线虫是最多样和最丰富的多细胞生物群之一，而且因为它们对人类活动具有重大影响（例如，植物寄生虫与农业、脊椎动物寄生虫与畜牧业、人类健康）。作为鉴定标本的大量参考来源，UCDNC对于生物学相关研究中的精确鉴定非常有用。该项目将提供一个新的储存载玻片的系统，以减少标本损坏的频率，便于监测载玻片的变质情况，并增加为研究目的获取标本的机会。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），是必要的，以确保长期保存的标本。

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.
