Ferns and their relatives ("pteridophytes") arose approximately 420 million years ago and were the dominant plant groups for hundreds of millions of years afterwards. Today the pteridophytes are outnumbered by the diversity and abundance of other plant groups, such as those that bear flowers, but they remain diverse (with around 12,000 species), ecologically important, and are found throughout the world. This Thematic Collections Network (TCN) brings together 9 core institutions whose goal is to make digital images and data on the distribution and biology of 1.6 million fossil and modern ferns and their relatives available to researchers. This effort includes 39 US Museums and Herbaria that will provide on-line access of collections data to researchers worldwide who will be able to address pressing questions about the evolution, distribution, and biology of land plants. This project would train students and reach the public through teacher training opportunities, the development of curriculum and education boxes and through the production of informative science videos. The Pteridological Collections Consortium TCN is an interdisciplinary initiative that will database, image, and disseminate information on an unprecedented number of extant and fossil pteridophyte specimens. The combining of neo- and paleobotanical collections data will produce an online resource via a Symbiota framework to enable research on the distribution, ecology, genetics, and deep-time evolution of an important group of vascular plants. Pteridophytes are important because they 1) are relatively diverse and have extensive global distributions, 2) are associated with evolutionary innovations that shaped adaptations to terrestrial ecosystems, 3) they are sensitive to local environmental conditions and play important roles in modern communities, and 4) they have an excellent fossil record for addressing deep-time questions. This award is made as part of the National Resource for Digitization of Biological Collections through the Advancing Digitization of Biological Collections program and all data resulting from this award will be available through the national resource (iDigBio.org).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.

蕨类植物和它们的近缘植物(“蕨类植物”)大约出现在4.2亿年前，在此后的数亿年里一直是主要的植物类群。今天，蕨类植物的数量超过了其他植物群的多样性和丰富性，例如那些开花的植物群，但它们仍然多样化(约有12,000个物种)，具有重要的生态意义，在世界各地都有分布。这个主题收藏网络(TCN)汇集了9个核心机构，他们的目标是向研究人员提供关于160万化石和现代蕨类及其近缘植物的分布和生物学的数字图像和数据。这一努力包括39个美国博物馆和草本植物，它们将为世界各地的研究人员提供在线收藏数据访问，他们将能够解决有关陆地植物的进化、分布和生物学的紧迫问题。该项目将通过教师培训机会、开发课程和教育盒以及制作内容丰富的科学录像，对学生进行培训，并向公众宣传。蕨类植物收藏联盟TCN是一项跨学科倡议，将对数量空前的现存和化石蕨类植物标本进行数据库、图像和信息传播。新植物学和古植物学采集数据的结合将通过共生区框架产生一个在线资源，使人们能够研究一类重要维管植物的分布、生态学、遗传学和深层进化。蕨类植物之所以重要，是因为它们1)相对多样化，具有广泛的全球分布，2)与形成陆地生态系统适应的进化创新有关，3)它们对当地环境条件敏感，并在现代群落中发挥重要作用，4)它们在解决深层问题方面有很好的化石记录。该奖项是作为通过推进生物收藏数字化计划的生物收藏数字化国家资源的一部分颁发的，由此产生的所有数据将通过国家资源(iDigBio.org)获得。该奖项反映了NSF的法定使命，并已通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
