Biosystematic studies and monograph of the goldenrod genus Solidago L. (Compositae: Astereae)

拟议研究的主要目标是完成一部黄花属植物专著所需的生物系统和命名研究。此外，对Asters的长期研究也将继续进行。一枝黄花包括分布在北美、南美洲和整个欧亚大陆的100多种植物，其中几种北美本土物种现在是欧洲和东亚的主要入侵植物。申请者已经在Solidago工作了40年，见过该领域的大多数N.A.物种，并培育了来自南美洲和欧亚大陆的其他物种。与研究人员在基于DNA的系统发育方面的合作将继续下去。该属内所有类群的细胞地理学和多变量形态计量学分析已接近完成。在过去的五年里，对2000多个标本进行了形态研究，以解决物种限制，扩大北美植物志申请人和《中国的植物志》英文版对该属的治疗工作，并解决书中指出的问题。数十份关于该属内物种群的细胞地理学和形态分析的手稿将提交出版。为了创建详细的分布图并解决命名问题，需要访问加拿大、欧洲和美国的大型草本植物。申请人对这些有时常见、分布广泛、有时非常稀有、分布狭窄的植物物种拥有罕见的、非常高水平的知识，这些植物物种构成了夏季花卉群落的重要组成部分，并覆盖了该属多大陆分布的大部分地区。将这些知识转化为一本详细的、插图丰富的整个属的专著一直是一个长期的目标。这本专著的完成确保了这些知识以最有用的形式被传递给生态学家、博物学家和普通公众：一本书，其中包括描述、分布图、线条插图和每种黄花的详细讨论，这将有助于识别一个被广泛认为是最具分类学挑战的开花植物属的成员。

The main objective of the proposed research is to complete biosystematic and nomenclatural studies needed for a monograph of the entire goldenrod genus Solidago (Compositae: Astereae). As well, long term research on asters will continue. Solidago includes more than 100 species distributed in North and South America and across Eurasia with several native North America species now being dominant invasive plants in Europe and eastern Asia. The applicant has worked on Solidago for four decades and has seen most N.A. species in the field and cultivated others from South America and Eurasia. Collaboration with researchers on a DNA based phylogeny will continue. Cytogeographic and multivariate morphometric analyses of all groups within the genus are nearly complete. During the past five years over 2000 specimens were scored for morphogy studies done to resolve species limits and to expand work done for the treatments of the genus by the applicant for Flora North American and the English language version of the Flora of China and to resolve problems noted in the books. Dozens of manuscripts on cytogeography and morphological analyses of species groups within the genus will be submitted for publication. Visits to large herbaria across Canada, in Europe and in the U.S. are needed to create detailed distribution maps and resolve nomenclature problems. The applicant has acquired a rare, very high level of knowledge on these sometimes common and widely distributed, sometimes very rare and narrowly distributed plant species that make up important parts of floral communities in the summer and fall over much of the multi-continent distribution of the genus. Turning this knowledge into a detailed, richly illustrated monograph of the entire genus has been a long term goal. Completion of the monograph ensures that this knowledge is set down in the most useful format for transfer to ecologists, naturalists and the general public: a book with descriptions, distribution maps, line drawing illustrations, and detailed discussions of each kind of goldenrod that will facilitate identification of members of a genus widely acknowledged to be a one of the most taxonomically challenging genera of flowering plants.
