This project will complete the transfer and integration of some 22,000 specimens of the moss genus Sphagnum from Binghamton University into the Duke University herbarium. The specimens will be transferred to archival quality specimen packets and associated collection information will be uploaded to appropriate databases to make specimen information available to researchers and citizen scientists. Sphagnum is both a genus of plants and an entire ecosystem. Sphagnum-dominated peatlands are estimated to store 25-30% of the total terrestrial carbon pool and are for that reason critical to understanding and management of the global climate. Sphagnum is currently under active development as a model for studying the impacts of changing climate on plants, and the combined Duke-Binghamton Sphagnum herbarium will be an irreplaceable resource to document geographic and ecological variation in Sphagnum peat mosses. It is well established that ecological function, including levels of carbon sequestration, varies with regard to both Sphagnum species and geographic setting. The augmented Duke University collection, with over 50,000 specimens of Sphagnum, will comprise the largest collection of this group in the world and will have unparalleled importance. This project supports the rescue of an at-risk collection of the moss genus Sphagnum from Binghamton University (BING) and its integration with the L.E. Anderson Bryophyte Herbarium at Duke University (DUKE). The collection will be curated both physically and taxonomically to preserve and increase its value as a resource for research and teaching. Most of the BING specimens are currently packeted in non-archival quality paper on herbarium sheets. Many of the packets, including many holding type specimens, are disintegrating, with labels and packets in various stages of detachment. All transferred specimens will be properly curated; they will be re-packeted with new labels, organized using the geographic system currently employed in the DUKE bryophyte herbarium, digitized, and made accessible via the Bryophyte Portal (bryophyteportal.org/portal/) and iDigBio.org. The taxonomy of these collections will be updated based on recent research findings of Sphagnum taxonomy. This activity will involve microscopic examination of specimens belonging to groups for which taxonomic revisions have been completed.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将完成从宾厄姆顿大学到杜克大学植物标本室的大约22000个苔藓属Sphagnum标本的转移和整合。这些标本将被转移到具有档案质量的标本包中，相关的收集信息将上传到适当的数据库，以便研究人员和公民科学家可以获得标本信息。水藻既是一个植物属，也是一个完整的生态系统。据估计，以泥炭为主的泥炭地储存了陆地总碳库的25-30%，因此对理解和管理全球气候至关重要。目前，作为研究气候变化对植物影响的模型，Sphagnum正处于积极发展阶段，杜克-宾汉姆顿Sphagnum植物标本馆将成为记录Sphagnum泥炭苔藓地理和生态变化的不可替代的资源。众所周知，生态功能，包括碳固存水平，在泥鳅种类和地理环境方面都是不同的。扩充后的杜克大学收集了超过50,000个泥鳅标本，将成为世界上最大的泥鳅收藏，具有无与伦比的重要性。该项目支持对宾汉姆顿大学（Binghamton University）濒临灭绝的苔藓属Sphagnum的抢救，并将其与杜克大学（Duke）的L.E. Anderson苔藓植物标本馆整合。这些藏品将在物理和分类上进行管理，以保存和增加其作为研究和教学资源的价值。大多数BING标本目前都是用非档案质量的纸张包装在植物标本馆的纸上。许多包，包括许多持有型标本，正在解体，标签和包处于不同的分离阶段。所有转移的标本将妥善保管；它们将被重新包装上新的标签，使用杜克大学苔藓植物标本馆目前使用的地理系统进行组织，数字化，并通过苔藓植物门户网站（bryophyteportal.org/portal/）和iDigBio.org进行访问。本文将根据近年来藻属植物分类的研究成果，对其分类进行更新。这项活动将包括对已完成分类学修订的群体所属标本进行显微镜检查。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
