Abstract

Abstract. The Austral High Andean area extends from south-eastern Mendoza, Argentina, to the southernmost tip of South America in the form of isles on the peaks of the Andes range. The objective of this biogeographic regionalisation study was to characterise this area. Individual tracks were made on the basis of the distribution maps of 232 species of vascular plants present in the area, from which localities were identified and georeferenced. A parsimony analysis of endemicity (PAE) was used to obtain a generalised track. The results support an area of endemism located mainly in the Neuquén province, which is treated as a district of the Patagonian province that belongs to the Patagonian subregion of the Andean region. This track analysis is a preliminary contribution for understanding the distributional patterns of the High Andean biota within an evolutionary biogeographic framework.

基于维管植物分类群的巴塔哥尼亚省澳大拉高安第斯地区的生物地理特征

摘要澳大拉高安第斯地区从阿根廷门多萨东南部以安第斯山脉山峰上的岛屿形式延伸至南美洲最南端。这项生物地理学区域化研究的目的是对该地区进行表征。根据该地区232种维管植物的分布图进行了单独的追踪，从中确定了地点并进行了地理参考。使用地方性的简约分析（PAE）来获得广义轨迹。研究结果支持了一个主要位于Neuquén省的地方病地区，该地区被视为巴塔哥尼亚省的一个区，属于安第斯地区的巴塔哥尼亚区域。这一轨迹分析是在进化生物地理学框架内理解高安第斯生物群分布模式的初步贡献。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
