Abstract. Studies on ecological successions have a long tradition and have strongly contributed to the understanding of community assembly, niche theory, and ecosystem structure and functionality. Reports on ecological successions are however mostly restricted to one or two taxonomic groups, neglecting the mutual influences and dependencies between multiple taxonomic groups that are the building blocks of diverse communities. We introduce the Alpine research platform Odenwinkel to promote observational and experimental research on the emergence of multidiversity and ecosystem complexity. We established n= 140 permanent plots along the successional gradient of the forefield of the Odenwinkelkees glacier at the end of the Stubachtal valley in the Hohe Tauern range (Hohe Tauern National Park, Land Salzburg, Austria). In summer 2019 we completed a first full inventory of biotic and abiotic characteristics of these plots covering the diversity and composition of vascular plants, bryophytes, arthropods, and other animals, bacteria and fungi as well as some geomorphologic properties. In this paper we introduce the design of the research platform and show first results. While focusing on the diversity and composition of vascular plants along the successional gradient, we also provide data on the diversity of animals, bacteria, and fungi. The Odenwinkel platform will be available as a long-term ecological research site where researchers from various disciplines can contribute to the accumulation of knowledge on ecological successions and on how interactions between various taxonomic groups structure ecological complexity in this Alpine environment.

Ödenwinkel：一个高山平台，用于对多样性和生态系统复杂性的出现进行观察和实验研究

摘要。生态演替研究有着悠久的传统，对理解群落组装、生态位理论以及生态系统结构和功能做出了重大贡献。然而，关于生态演替的报告大多仅限于一两个分类群，而忽略了作为不同群落基石的多个分类群之间的相互影响和依赖关系。我们引入了阿尔卑斯研究平台 Odenwinkel，以促进对多样性和生态系统复杂性的出现的观察和实验研究。我们沿着位于 Hohe Tauern 山脉（奥地利萨尔茨堡州的 Hohe Tauern 国家公园）Stubachtal 山谷尽头的 Odenwinkelkees 冰川前场的连续梯度建立了 n=140 个永久地块。2019 年夏季，我们完成了这些地块的生物和非生物特征的首次完整清单，涵盖维管植物、苔藓植物、节肢动物和其他动物、细菌和真菌的多样性和组成以及一些地貌特征。在本文中，我们介绍了研究平台的设计并展示了初步结果。在关注沿演替梯度维管植物的多样性和组成的同时，我们还提供了关于动物、细菌和真菌多样性的数据。Odenwinkel 平台将作为一个长期的生态研究站点提供，来自不同学科的研究人员可以在那里为生态演替以及不同分类群之间的相互作用如何构建阿尔卑斯山环境中生态复杂性的知识积累做出贡献。
