Fig. 2 Partial least squares (PLS) correlation loading plots for models explaining relationships between biomass of different fungal guilds in relation to a all environmental variables, b soil properties and c variables related to climatic conditions. Blue and red colours of circles indicate explanatory and response variables, respectively. Values of R2 indicate the percentage of variation explained by the models and values of Q2 represent cross-validated explained variances and indicate how well the models predict new data. The areas of the circles are proportional to the variable importance (VIP) scores in the models and their placements indicate loading scores of the different factors. All projections (a–c) resulted in one significant component (PLS 1)
