9522034 Magill Mosses, although conspicuous in tropical forests, are among the more neglected groups of organisms, especially for tropical parts of the world. There are few institutions in North America with significant resources for their study, but one such is the Missouri Botanical Garden, St. Louis, where Drs. Robert Magill and Bruce Allen have pulled together a team of colleagues for a five-year enterprise studying mosses of the family Meteoriaceae. Traditional morphological investigations, supplemented when possible with gametophyte culturing studies, will be enhanced with additional data from molecular analyses, including DNA sequencing with assistance from colleagues at Washington University. Field collecting in Central and South America and in Africa will target both taxa and regions needing better samples, and will make possible biogeographical studies of current and historical distribution patterns. Improved taxonomic understanding of species diversity in these mosses and plausible hypotheses of their evolutionary and phylogenetic relationships will result from the work. In particular, tests can be made of the idea that the pendent, epiphytic habit of many of the Meteoriaceae has evolved convergently or independently a number of times, in various parts of the New and Old World tropics. Training of new graduate and postdoctoral students is a significant component of the project, through associations with three universities in the area, Washington University, the University of Missouri-St. Louis, and St. Louis University. Formal course work as well as laboratory and museum study comprise the training program, along with field work and apprenticeship in taxonomic monographic research. Computerization of many aspects of the enterprise, including specimen databasing, character analyses, and phylogenetic inference, enhances the timely dissemination of results through the Missouri Botanical Garden's World Wide Web service.

小马吉尔9522034 苔藓，虽然在热带森林中很显眼，但在世界的热带地区，特别是在热带地区，是更被忽视的生物群体之一。 北美很少有机构拥有大量研究资源，但圣路易斯的密苏里州植物园就是其中之一，罗伯特·马吉尔博士和布鲁斯·艾伦博士在那里召集了一个同事团队，开展了一项为期五年的研究。蔓苔科苔藓的企业。 传统的形态学研究，在可能的情况下辅以配子体培养研究，将得到分子分析的额外数据的加强，包括在华盛顿大学同事的协助下进行DNA测序。 在中美洲、南美洲和非洲进行的实地采集将针对需要更好样本的分类群和地区，并将使对当前和历史分布模式的地理学研究成为可能。 这些苔藓的物种多样性和合理的假设，其进化和系统发育关系的分类学的理解将导致从工作。 特别是，可以测试的想法，悬垂，附生习性的许多蔓藓科已经进化收敛或独立的次数，在不同地区的新的和旧的世界热带地区。 通过与该地区的三所大学（华盛顿大学、密苏里-圣路易斯大学和圣路易斯大学）的合作，培训新的研究生和博士后学生是该项目的一个重要组成部分。 正式的课程工作以及实验室和博物馆研究包括培训计划，沿着野外工作和分类学专题研究的学徒。 企业的许多方面的计算机化，包括标本数据库，字符分析和系统发育推断，通过密苏里州植物园的万维网服务，提高了结果的及时传播。
