Plant species diversity of black alder-dominated forests was studied in three biogeographical regions (Alpine, Continental and Pannonian) of Central Europe. They were represented by regions of the Polish Plain (Continental), the High Western Carpathians and Matricum of the Western Carpathians (Alpine) and the Pannonian lowland (Pannonian). We analysed 35 plots per region in order to identify: i) local alpha (α) diversity defined as the counted number of plant taxa occurring in a single sampling plot, ii) amongst-site beta (β) diversity, iii) regional (γ) diversity defined as the total species richness of all sampling plots and iv) zeta diversity (ζ) as a generalisation of beta diversity. We recorded a total of 432 vascular plant taxa in all bioregions; more than 13% were alien plants. Statistically significant differences in species richness (α) of both native and alien plants were found between assemblages of the regions. The High Western Carpathians showed the highest native and the lowest alien plant species richness. Total β-diversity was high in all regions, but significantly differed amongst regions only for alien plant species. Cumulative native and alien species richness (γ) was the highest and lowest in the High Western Carpathians and Matricum of Western Carpathians, respectively. Our results identified the High Western Carpathians as a hotspot for diversity of native plants in Central European black alder-dominated forests.
在中欧的三个生物地理区域（阿尔卑斯、大陆和潘诺尼亚）对以黑桤木为主的森林的植物物种多样性进行了研究。这些区域分别由波兰平原地区（大陆）、西喀尔巴阡山脉高地和西喀尔巴阡山脉的马特里库姆地区（阿尔卑斯）以及潘诺尼亚低地（潘诺尼亚）代表。我们对每个区域分析了35个样地，以确定：i）局部α多样性，定义为单个采样样地中出现的植物分类单元数量；ii）样地间β多样性；iii）区域γ多样性，定义为所有采样样地的总物种丰富度；iv）ζ多样性，作为β多样性的一种概括。我们在所有生物区域共记录了432种维管束植物分类单元；超过13%是外来植物。在不同区域的组合之间，本地植物和外来植物的物种丰富度（α）存在统计学上的显著差异。西喀尔巴阡山脉高地的本地植物物种丰富度最高，外来植物物种丰富度最低。所有区域的总β多样性都很高，但仅外来植物物种在区域间存在显著差异。累积本地和外来物种丰富度（γ）分别在西喀尔巴阡山脉高地和西喀尔巴阡山脉的马特里库姆地区最高和最低。我们的结果确定西喀尔巴阡山脉高地是中欧以黑桤木为主的森林中本地植物多样性的一个热点地区。
