Table 1 Correlation between the tree species’ relative basal area (in %) in the plots and the ordination (DCA) axes 1 to 4. a Characteristics of the first four axes in the analysis with all tree species. b Association of the most dominant tree species (according to their relative basal area in %) to the DCA axes 1 and 2 (expressed as direction cosines) and correlation of the species to the ordination space (given are the R² and p values). While the data set with all tree species was used to establish the ordination in a, all oak species were pooled to Quercus spp. in analysis (b) and this species group was only correlated post hoc to the ordination space

From: Climate warming-induced replacement of mesic beech by thermophilic oak forests will reduce the carbon storage potential in aboveground biomass and soil
