0516013Allen The mosses of Central America form one of the richest moss floras in the Neotropics. The Moss Flora of Central America is a revisionary flora, that is to say a rigorous scientific account of the 921 moss species found in Central America, analyzed from field, herbarium, and literature sources. This fourth part is the final section of the flora. The Moss Flora of Central America is based upon the study of historical collections held in major U.S. herbaria as well as recent collections made by the author and colleagues. It authenticates modern species names, while accounting for older non-valid names, gives detailed descriptions of each plant's form, an account of the habitat and ecology of each species, provides the distribution of the species both within Central America and world-wide, and presents detailed discussions of the unique features of each species as well as the best ways of distinguishing species from each other. Differences between moss species are often difficult to discern, and so each species in the flora is illustrated with a full page of line drawings. Also, lists of all previous illustrations of the species are given. Publication of the Moss Flora of Central America is in English, with the text of the flora and accompanying specimen databases also available on the web. The flora is available in Spanish, and this version of the flora can also be accessed on the web. The Moss Flora of Central America will stimulate the study of mosses throughout the Neotropics by providing in a single reference (in English and Spanish) diagnostic keys and descriptions to all the mosses in the region. It will involve the naming of large numbers of un-named collections that have accumulated in herbaria over the last twenty-five years. These collections, as well as duplicate material that will be widely distributed, will form the basis of a primary reference collection that will greatly enhance the ability of scientists to recognize species throughout the Neotropics. This will allow mosses to be meaningfully incorporated into many other interdisciplinary studies, most notably ecological studies. Furthermore, this assessment of Central American mosses can also be used to support or criticize studies done with other forms of plants or even animals in the region. Mosses occupy microhabitats that are extremely sensitive to changing physical conditions. In this time of suspected global warming and the uncertain impact of global climatic changes on world ecosystems, the Moss Flora of Central America will provide critical baseline bio-data from a crucial and ecologically sensitive part of the world. This baseline data in conjunction with future studies on the mosses of Central America will be useful in assessing the effects of climatic changes in this critical region of the world.

0516013艾伦中美洲的苔藓是新热带地区最丰富的苔藓植物区系之一。《中美洲苔藓植物群》是一本修订版的植物群，也就是说，它对中美洲发现的921种苔藓进行了严格的科学描述，并从野外、植物标本室和文献来源进行了分析。第四部分是植物群的最后一部分。《中美洲苔藓植物群》是基于对美国主要植物标本馆中历史收藏品的研究以及作者及其同事最近的收藏品。它鉴定了现代物种名称，同时解释了旧的无效名称，详细描述了每种植物的形式，每个物种的栖息地和生态，提供了中美洲和世界范围内的物种分布，并详细讨论了每个物种的独特特征以及区分物种的最佳方法。苔藓物种之间的差异往往很难辨别，因此植物群中的每一个物种都用一整页的线条图来说明。此外，所有以前的插图的物种的列表给出。《中美洲苔藓植物群》以英文出版，植物群的文本和附带的标本数据库也可在网上查阅。该植物群有西班牙文版本，该版本的植物群也可在网上查阅。 《中美洲苔藓植物群》将通过提供该地区所有苔藓的单一参考（英语和西班牙语）诊断关键词和描述，促进整个新热带地区苔藓的研究。它将涉及对过去二十五年来在植物标本馆中积累的大量未命名藏品的命名。这些收集，以及重复的材料，将被广泛分发，将形成一个主要的参考收集，这将大大提高科学家的能力，以识别整个新热带地区的物种的基础。这将使苔藓有意义地纳入许多其他跨学科的研究，最显着的生态研究。此外，对中美洲苔藓的评估也可用于支持或批评对该地区其他形式的植物甚至动物进行的研究。苔藓占据着对变化的物理条件极其敏感的微生境。在这个怀疑全球变暖和全球气候变化对世界生态系统的影响不确定的时期，中美洲苔藓植物群将提供来自世界上一个关键和生态敏感地区的关键基线生物数据。这一基线数据与今后对中美洲苔藓的研究相结合，将有助于评估气候变化对世界这一关键区域的影响。
