Abstract

The Altai Mountains of central Asia are biologically rich and comprise a wide diversity of ecosystems and lineages, including numerous endemic vascular plant species. Here we provide an updated checklist of the endemic vascular flora of the Altai Mountains with more taxa and higher geographic resolution than previously reported, as well as first molecular data and specimen images for many of these species. This flora is now known to contain 321 endemic species distributed in 34 families, many of which are narrowly restricted to one subregion of the Altai. The Fabaceae has given rise to the most endemic species in the Altai (74 spp.), and most of this diversity is found in the large and ecologically important genera Astragalus and Oxytropis. Approximately 60% of the endemic flora was imaged and successfully barcoded with at least one of three common DNA barcoding loci, and a phylogenetic tree based upon these loci is also presented to display the evolutionary breadth of endemism in the Altai. The distribution of each endemic species is presented in terms of a standard geographic subdivision of the Altai region, with general conservation priorities discussed based on areas currently afforded protected status.
西伯利亚生物多样性热点地区阿尔泰山特有维管植物区系的分布分析、更新清单和DNA条形码
中亚的阿尔泰山脉生物资源丰富,包括多种多样的生态系统和谱系,包括许多特有的维管植物物种。本文提供了一份最新的阿尔泰山特有维管植物区系清单,其中包括比以前报道的更多的分类群和更高的地理分辨率,以及许多这些物种的第一个分子数据和标本图像。目前已知该植物群包含321种特有种,分布于34科,其中许多仅局限于阿尔泰的一个分区域。在阿尔泰地区,豆科植物产生了最特有的物种(74种),而这种多样性主要存在于大型和生态重要的黄芪属和棘豆属中。大约60%的特有菌群被成像并成功地用三个常见的DNA条形码位点中的至少一个成功地进行了条形码,并基于这些位点建立了一个系统发育树,以显示阿尔泰特有的进化广度。每一特有物种的分布都是按照阿尔泰地区的标准地理细分来介绍的,并根据目前获得保护地位的地区讨论了一般的保护优先事项。

期刊介绍: Systematics and Biodiversity is devoted to whole-organism biology. It is a quarterly, international, peer-reviewed, life science journal, without page charges, which is published by Taylor & Francis for The Natural History Museum, London. The criterion for publication is scientific merit. Systematics and Biodiversity documents the diversity of organisms in all natural phyla, through taxonomic papers that have a broad context (not single species descriptions), while also addressing topical issues relating to biological collections, and the principles of systematics. It particularly emphasises the importance and multi-disciplinary significance of systematics, with contributions which address the implications of other fields for systematics, or which advance our understanding of other fields through taxonomic knowledge, especially in relation to the nature, origins, and conservation of biodiversity, at all taxonomic levels. The journal does not publish single species descriptions, monographs or applied research nor alpha species descriptions. Taxonomic manuscripts must include modern methods such as cladistics or phylogenetic analysis.
