Environmental factors influencing the species composition of acidophilous grassland patches in agricultural lanscapes

Popis výsledku v původním jazyce

The acidophilous grasslands of the south-western part of the Czech-Moravian Highlands in the Czech Republic were substantially reduced in the 20th century. These patches are addressed in this paper, in terms of the impacts of their size, isolation, and the quality of the surrounding land cover. Species recorded in the acidophilous grasslands are categorized by hemeroby and life form. Multivariate gradient analysis revealed that the greatest proportions of the variability of species data were explained by two local variables (soil pH and the shape of the patch). Some species groups were also substantially influenced by microrelief. The importance of the surrounding land cover for the species composition was studied by means of regression trees. An assumption that, aside from local factors (soil pH and micro-relief), the species composition is significantly influenced by the heterogeneity of the surrounding landscape, was confirmed.
