From: Southern Carpathian ultramafic grasslands within the central-southeast European context: syntaxonomic classification and overall eco-coenotic patterns

Fig. 3

Ordination of the 120 relevés of ultramafic grasslands in the space determined by the two most important NMDS axes, from the total of three axes extracted (final stress = 0.0987; linear R-square = 0.916); the length and orientation of the two environmental vectors stem from the outcome of the linear fitting of elevation and slope against the relevé scores (see Table 8). PA = Plantago serpentinae–Armerietum halleri; AsA = Asplenio serpentini–Achnatheretum calamagrostis; SP = Sileno saxifragae–Plantaginetum holostei; MP = Minuartio frutescentis–Plantaginetum holostei; Ah = Armerietum halleri; AaA = Artemisio albae–Achnatheretum calamagrostis; OF = Onosmo pavlovae–Festucetum dalmaticae; PP = Poo molinerii–Plantaginetum holostei; AP = Anthemido–Plantaginetum holostei
