From: Climatic and anthropogenic factors explain the variability of Fagus sylvatica treeline elevation in fifteen mountain groups across the Apennines

Fig. 5

Comparative multivariate data analysis among mountain groups. Panel a shows hierarchical ordination of Apennine mountain groups according to Euclidean distance calculated on treeline elevation (TLE): maximum TLE, minimum TLE, average TLE, Δ average TLE north aspect – average TLE south aspect, Δ maximum TLE – average TLE variables. Grey numbers in correspondence of the nodes report p value, in bold significant differences. Panel b shows specific association of treeline attributes with Apennine mountain groups, clustering of mountain groups is performed through overlay function of Euclidean distance. Panel c shows the geographical distribution of the fifteen selected mountain groups throughout the Apennine Fagus sylvatica range
