Additional file 1 of Southern Carpathian ultramafic grasslands within the central-southeast European context: syntaxonomic classification and overall eco-coenotic patterns

Additional file 1: Appendix S1. Synoptic table displaying the species frequencies (%) of occurrence in several ultramafic herbaceous communities from central Europe (columns 1–2), Southern Carpathians (colums 3–6), western Balkans (columns 7–8), central Balkans (column 9) and southern Balkans (column 10). Values in bold (within grey-shaded cells) correspond to the regional differential species in the Southern Carpathians. Abbreviations: Ah = Armerietum halleri; DA = Diantho gratianopolitanae–Armerietum halleri; PA = Plantago serpentinae–Armerietum halleri; AsA = Asplenio serpentini–Achnatheretum calamagrostis; SP = Sileno saxifragae–Plantaginetum holostei; MP = Minuartio frutescentis–Plantaginetum holostei; AaA = Artemisio albae–Achnatheretum calamagrostis; PP = Poo molinerii–Plantaginetum holostei; OF = Onosmo pavlovae–Festucetum dalmaticae; AP = Anthemido–Plantaginetum holostei.
