A Moss Flora of Central America, Part 4

中美洲的苔藓形成了新热带地区最丰富的苔藓植物区系之一。中美洲的苔藓植物区系是一种修正性的植物区系，也就是说，对在中美洲发现的921种苔藓物种进行了严格的科学描述，从野外、植物标本馆和文献来源进行了分析。第四部分是植物区系的最后一部分。中美洲的苔藓植物群是基于对美国主要草本植物的历史收藏以及作者和同事最近收藏的研究。它验证了现代物种名称，同时说明了较老的无效名称，详细描述了每种植物的形态，说明了每种物种的栖息地和生态，提供了这些物种在中美洲和世界范围内的分布情况，并详细讨论了每种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，所以植物区系中的每一种都用一整页的线条画来说明。此外，还给出了该物种以前的所有插图清单。《中美洲苔藓植物区系》以英文出版，植物区系文本和所附标本数据库也可在网上查阅。FLORA有西班牙语版本，这个版本的FLORA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(英文和西班牙文)诊断检索表和描述，促进对整个新热带地区苔藓的研究。它将涉及命名在过去25年中在草本植物中积累的大量未命名的收藏品。这些收集，以及将广泛分布的复制材料，将构成主要参考收集的基础，这将极大地提高科学家识别整个新热带地区物种的能力。这将使苔藓能够有意义地被纳入许多其他跨学科研究，尤其是生态学研究。此外，这种对中美洲苔藓的评估也可以用来支持或批评用该地区其他形式的植物甚至动物所做的研究。苔藓占据的微生境对变化的物理条件极其敏感。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候，中美洲的苔藓植物群将提供来自世界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将有助于评估气候变化对世界这一关键区域的影响。

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.
