Formal definitions of Slovakian mire plant associations and their application in regional research

摘要: We applied the Cocktail method to a large data set of 4 117 releves all Slovak vegetation types with aim create formalised definitions Slovakian mire plant associations. defined 21 groups species statistical tendency joint occurrences in vegetation. These differed substantially their position along pH/calcium gradient. further 24 associations according presence and/or absence certain strong dominance some species. Only six traditional were not possible be reproduced this way. our regional mires from surrounding Vysoke Tatry Mts. Combined frequency-positive fidelity index has led classification majority plots into ten When obtained Cocktail-based and cluster analysis compared respect measured pH conductivity study region, 82% pairs significantly either or water former 69% latter one.
