A Moss Flora of Central America, Part 4

[05:16 . 13]艾伦中美洲的苔藓是新热带地区最丰富的苔藓区系之一。《中美洲苔藓植物区系》是一本修订的植物区系，也就是说，它是对在中美洲发现的921种苔藓物种进行严格的科学描述，分析了野外、植物标本馆和文献资料。第四部分是植物志的最后一部分。《中美洲苔藓植物区系》是基于对美国主要植物标本馆的历史收藏和作者及其同事最近收集的资料的研究。它验证了现代的物种名称，同时考虑到古老的无效名称，对每种植物的形态进行了详细的描述，对每种植物的栖息地和生态进行了描述，提供了每种植物在中美洲和世界范围内的分布，并详细讨论了每种植物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通常很难辨别，因此植物区系中的每个物种都用一整页的线条图加以说明。此外，还提供了该物种以前所有插图的列表。《中美洲苔藓植物区系》以英文出版，植物区系的文本和随附的标本数据库也可在网上找到。该植物区系有西班牙语版本，这个版本的植物区系也可以在网上访问。《中美洲苔藓植物区系》将通过提供该地区所有苔藓的单一参考（英语和西班牙语）诊断钥匙和描述，促进整个新热带地区苔藓的研究。它将涉及为过去25年来在植物标本室中积累的大量未命名的藏品命名。这些收集，以及将广泛分发的重复材料，将构成主要参考收集的基础，这将大大提高科学家在整个新热带地区认识物种的能力。这将使苔藓被有意义地纳入许多其他跨学科的研究，尤其是生态学研究。此外，对中美洲苔藓的评估也可以用来支持或批评对该地区其他形式的植物甚至动物所做的研究。苔藓占据着对变化的物理条件极其敏感的微栖息地。在这个怀疑全球变暖的时代，以及全球气候变化对世界生态系统的不确定影响，中美洲的苔藓植物区系将提供来自世界上一个重要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地区的影响。

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.
