Abstract

Methods of macroevolutionary systematics as recently modified are explained and applied to the genus Anoectangium Schwägr. (Pottiaceae) in hyperoceanic areas of coastal northwestern North America. It was revealed that this area harbored species like those reported for the Himalayan region of northern India. Keys are provided for North American and Himalayan species of the genus. A macroevolutionary analysis, detailed in the Methods section, distinguishes and gives relationships between the species. There is strong Bayesian support for progenitor-descendant pairs and lineages. Anoectangium thomsonii Mitt. is considered a synonym of A. aestivum (Hedw.) Mitt. Anoectangium crassinervium Mitt. is transferred to Molendoa Lindb., under a nomen novum with A. handelii Schiffn. as a synonym. Anoectangium incrassatum Broth., related to the Asian A. clarum Mitt., is reported as a well-characterized species from the West Indies. Anoectangium stracheyanum Mitt. is re-lectotypified. Distinctions between A. aestivum and A. euchloron (Schwägr.) Spruce in the New World are clarified. Causal explanations in systematics are equated with entropy maximization in Shannon information analysis in the context of serial descent. A Pleistocene species pump hypothesis is advanced to explain the stenomorphic populations of species of the genus in eastern North America.

宏观进化评价方法的扩展、巩固和例证——以北美和喜马拉雅地区的苔藓藓属植物为例

解释了最近修改的宏观进化系统学方法，并将其应用于Anectangium Schwägr。（Pottiaceae）产于北美洲西北部沿海的远海地区。据透露，该地区有与印度北部喜马拉雅地区类似的物种。提供了该属北美和喜马拉雅物种的钥匙。方法部分详细介绍了宏观进化分析，区分并给出了物种之间的关系。有强大的贝叶斯支持祖-子配对和谱系。汤氏Anectangium thomsoii Mitt。被认为是a的同义词。夏令属（Hedw.）。粗糙无尾管。转移到Molendoa Lindb。，在与a.handelii Schiffin合作的新专辑下。作为同义词。Anectangium incassatum肉汤。，与亚洲A.clarum Mitt。，据报道，它是来自西印度群岛的一个特征良好的物种。stracheyanum Mitt。被重新选为型号。阐明了A.aestivum和A.euchloron（Schwägr.）云杉在新大陆的区别。系统学中的因果解释等同于序列下降背景下香农信息分析中的熵最大化。提出了更新世物种泵假说来解释该属物种在北美东部的狭窄种群。

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
