CSBR Natural History: Rehousing and inventory of fluid-preserved mollusks at the Academy of Natural Sciences

该项目将在费城自然科学学院(ANSP)清点5万多个液体保存的软体动物样本。旧瓶盖的失败率越来越高，这一问题将通过用档案材料制成的盖子更换来解决。该藏品包含来自140个国家的约150万份标本。濒危和灭绝的物种在1000多个样本中得到了代表，包括20多万个样本。许多液体保存的收藏品除了适合解剖外，还适合进行DNA分析。确保这些材料得到适当的存档，并确保有关的信息在网上可用，以支持世界各地关于软体动物生物学和保护的研究。该项目将对德雷塞尔大学的四名本科生进行软体动物系统学、分类学和策展技术方面的培训。每个学生将在ANSP担任为期六个月的全职策展助理，学习保护和保护技术。学生将获得软体动物多样性的介绍，并了解系统收集在进化和保护生物学研究中的价值。该项目将在2014年有1000多人参加的ANSP年度会员之夜和吸引约1500名参观者的年度费城贝壳展上向公众介绍。该项目将在档案材料中存放ANSP的41000个样本，并整合从其他机构收到的约9500个样本。藏品中的许多罐盖都是用胶木或钢材制成的，现在已知这些材料不能存档以保存液体。当盖子失效时，标本就会干涸，降低它们的科学价值；所有非档案盖子都将被档案盖子取代。罐子将从直接站在货架上移到铝制托盘中，这样就可以通过扫描整个托盘来检查液位，而不是一次拿起一个罐子。在DNA技术出现之前，人们假设从液体保存的收藏品中借出的样本在被解剖时会被销毁，因此ANSP要求提供类似的材料作为交换。然而，当样品被取消访问以进行破坏性采样时，通常不会记录下来。此外，在某些情况下，目录中没有记录除干酒外还有酒精酒的情况。因此，每个样本都将根据其数据库记录进行验证，从而产生流体保存的收藏品的当前库存。一个模块将被添加到数据库中，以记录样品在重新安置时的状况和采取的任何行动。该项目产生的所有数据将与iDigBio(https://www.idigbio.org/)，)共享，以确保研究人员和教育工作者能够访问。将通过国家科学计划网站(http://clade.ansp.org/malacology/collections/)和其他门户网站在线提供数据。

This project will inventory more than 50,000 samples of fluid-preserved mollusks at the Academy of Natural Sciences of Philadelphia (ANSP). The collection is threatened by the increasing failure rate of old jar lids, which will be addressed by replacing the lids with ones made of archival materials. The collection contains about 1.5 million specimens from 140 countries. Endangered and extinct species are represented in more than 1,000 samples containing more than 200,000 specimens. Much of the fluid-preserved collection is appropriate for DNA analysis, in addition to being suitable for dissections. Ensuring that this material is properly archived and that information about is available online supports research on molluscan biology and conservation throughout the world. The project will train four undergraduate students from Drexel University in molluscan systematics, taxonomy, and curatorial techniques. Each student will work full-time for six months as a curatorial assistant at ANSP, learning conservation and preservation techniques. Students will receive an introduction to molluscan diversity and learn about the value of systematic collections for research in evolutionary and conservation biology. The general public will be introduced to the project at the annual Members' Night at ANSP, which was attended by more than 1,000 people in 2014, and at the annual Philadelphia Shell Show, which attracts about 1,500 visitors.The project will rehouse in archival materials 41,000 samples from ANSP and integrate about 9,500 samples received from other institutions. Many of the jar lids in the collection are made of bakelite or steel, materials now known not to be archival for fluid preservation. When lids fail, the specimens dry out, reducing their scientific value; all non-archival lids will be replaced with archival ones. Jars will be moved from standing directly on shelves into aluminum trays, so that fluid levels can be checked by scanning entire trays rather than picking up one jar at a time. Before the advent of DNA technology, it was assumed that samples sent on loan from the fluid-preserved collection would be destroyed when they were dissected, so ANSP asked for similar material in exchange. However, it was not usually recorded when a sample had been deaccessioned for destructive sampling. Also, in some cases, the presence of an alcohol lot in addition to a dry lot was not recorded in the catalogue. Each sample will therefore be verified against its database record, yielding a current inventory of the fluid-preserved collection. A module will be added to the database to record the condition of the sample at the time of rehousing and any action taken. All data resulting from this project will be shared with iDigBio (https://www.idigbio.org/), ensuring accessibility to researchers and educators. Data will be made available online through the ANSP website (http://clade.ansp.org/malacology/collections/) and other portals.
