Species diversity of vascular plants in alpine vegetation of the Western Carpathian mountains on different spatial scales and its connection to soil pH

Alpine regions are hotspots of species diversity and are therefore at focal center of scientific interest. The research aiming to understand the influences and patterns that shape this unique environment, is complicated by mulitple metodological issues stemming from unclear definitions of used terms as well as the existence of various methodological approaches and their constrains/limitations. The breadth of the topic of species diversity, which can be viewed from multitude of perspectives, is also adding to complications. This work summarizes the most important information in available literature and addresses important correlations and trends in environmental variables and species diversity of alpine meadows in the areas of Malá Fatra, Nízke Tatry, Roháče, and Belianske Tatry. At the center of attention is the widely accepted theory of higher species richness in areas with basic, calcareous substrates compared to areas with acidic, silicate substrates in Europe. To confirm this theory at different spatial scales in alpine environment, hierarchical sampling was chosen. A total of 96 samples containing data on the presence/absence of plants and relevant environmental factors, including pH measurements, were obtained. The structure of these data was visualized using ordination techniques such as PCA...
