Fig. 3From: The influence of bioclimate on soil microbial communities of cork oakEvaluation of the main environmental factors affecting fungal (A) and bacterial (B) diversity. Non-metric multidimensional scaling (NMDS) analyses were performed using Bray-Curtis dissimilarity coefficients. Each symbol represents a different soil sample (three samples from each forest), with colours representing different forest bioclimates. Environmental variables were fitted onto the NMDS ordination. The arrows directions indicate positive correlations between continuous environmental factors and microbial assemblages. Tmax represents the maximum temperature in the warmest month, Tmin is the minimum temperature in the coldest month), Organic C is the organic carbon, Total N is the total nitrogen and C:N ratio is the carbon:nitrogen ratio. Only those factors that were significantly correlated with NMDS ordination axes (p < 0.05) are representedBack to article page
