Figure 2.
Effect of soil pH and vegetation type on mxaF, mch (a, b) genotype composition, and effect of soil pH, nitrate concentration, vegetation type on genotype composition of fae (c). Soil pH and nitrate concentration were used as vectors in CCA plots as they were significantly correlated to the respective genotype composition (Table 3). No data were available for mxaF of forest soil SEW 9. Thus, the data point of SEW 9 is missing in panel a. Closed circles, data from forest soils. Open circles, data from grassland soils. pH, soil pH; [NO3−], nitrate concentration; λ, eigen value.
