OPUS Career Cycad Biology monograph

项目摘要

In the plant tree of life, a group of plants of special interest are the cycads. The cycads are widely considered the world’s most endangered plants with most of the 380 living species considered threatened by extinction according to the International Union for the Conservation of Nature’s Red List of Threatened Species. These early plants are often termed living fossils because of their ancient origin over 300 million years ago and their prevalence during the age of the dinosaurs, a time in which they were much more widespread and diverse than they are today. The surviving cycads are particularly valuable for studying plant evolution because of their excellent fossil record. Even though they have changed little in outward appearance, these plants have many unique features, some of which are ancestral (primitive) and some of which are derived (advanced). To save them from extinction, we need to understand when those changes occurred through time and correlate them with environmental changes and other biotic factors. Furthermore, the chemistry of modern cycads is unique and has significant implications for human health, particularly in neurobiology. In a way, cycads serve as a Rosetta stone for plant evolution. This project will synthesize all available data on cycad biology and make those data accessible, via a web site, to a broad audience of researchers as well as to the community of people who are interested in and able to contribute significantly to cycad conservation efforts. This project will generate a complete, modern e-monograph and data repository of the Cycads. Many avenues of research will be opened in the areas of taxonomy, biogeography, genomics, and evolutionary biology. This e-monograph, hosted by The World List of Cycads, will serve to provide the resources, background, and basics for those pursuits. It will include original species descriptions, type specimens, synonyms, invalid and illegitimate nomenclature, and all published nomenclature at various taxonomic levels. There will be modern, parallel descriptions of all taxa accompanied by photographs and line art, as well as identification tools, distribution maps, habitat data with historic and contemporary photographs, ecology, structural data, chemical data, life cycle information, and phenology and pollination biology when known. The e-monograph will also include an illustrated glossary and sections on ethnobotany, vernacular names, phytochemistry, growth and development, and nitrogen fixation. The comprehensive synthesis undertaken here will benefit from the digitization of over 5000 historic and contemporary microscope slides made by C.J. Chamberlain on embryology and by Adriance Foster, Marion Johnson, and Knut Norstog on developmental anatomy and morphology. Relevant sections tied to black and white images published by these researchers, as well as those of PI Stevenson, will be digitized in color and incorporated into developmental pages, thereby providing more detailed information on cycad structure to the research community. Historic habitat photographs of cycads by Chamberlain, Norstog, and Stevenson will be scanned and added to the species descriptions and the geography and ecology sections.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.

在植物生命之树中，苏铁属植物被广泛认为是世界上最濒危的植物，根据国际红线自然保护联盟的数据，苏铁属植物中的大多数都被认为面临灭绝的威胁。这些早期植物通常被称为活化石，因为它们起源于 3 亿多年前，并且在恐龙时代盛行，当时它们的分布范围更加广泛和广泛。幸存的苏铁植物因其出色的化石记录而对研究植物进化特别有价值，尽管它们的外观变化不大，但它们具有许多独特的特征，其中一些是祖先的（原始的）。为了使它们免于灭绝，我们需要了解这些变化何时发生，并将它们与环境变化和其他生物因素联系起来。此外，现代苏铁的化学成分是独特的，对人类具有重大影响。健康，特别是在在某种程度上，苏铁植物充当植物进化的罗塞塔石碑，该项目将综合有关苏铁生物学的所有可用数据，并通过网站向广大研究人员和社区提供这些数据。对苏铁保护工作感兴趣并能够做出贡献的人们将生成一个完整的、现代化的苏铁电子专着和数据存储库，将在分类学、这本电子专着由苏铁世界名录主办，将为这些研究提供资源、背景和基础知识，其中包括原始物种描述、模式标本、同义词、无效和物种。非法命名法，以及所有已发布的不同分类学级别的命名法，将对所有分类单元进行现代、平行的描述，并附有照片和线条艺术，以及识别工具、分布图、带有历史的栖息地数据。以及已知的当代照片、生态学、结构数据、化学数据、生命周期信息以及物候学和授粉生物学。电子专着还将包括有关民族植物学、方言名称、植物化学、生长和发育以及氮的插图术语表和部分。这里进行的全面综合将受益于 C.J. 张伯伦胚胎学以及阿德里安斯·福斯特、马里昂·约翰逊和克努特制作的 5000 多张历史和当代显微镜幻灯片的数字化。 Norstog 关于发育解剖学和形态学的相关部分由这些研究人员以及 PI Stevenson 发表，将被数字化并纳入发育页面，为研究提供有关苏铁结构的更详细信息。张伯伦、诺斯托格和史蒂文森拍摄的苏铁类历史栖息地照片将被扫描并添加到物种描述以及地理和生态部分。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持。利用基金会的智力优势和更广泛的影响审查标准。
