Microbial-geochemistry associations in the serpentine soils from the SEP. a Landscape classification of the serpentine soils based on their microbial composition, considering the abundance of prokaryotes and fungi per phylogenetic class, and soil geochemistry. Inset is the distance graph showing the cut point for two clusters. b Microbial-geochemistry associations based on the Geochemical-Landscape classification of Fig. 4 and considering prokaryotic and fungal abundance for every location sampled. Three main components explained ~ 65% of the variance within the samples according to PCA: PC1 (32.1%), PC2 (18.3%) and PC3 (14.4%). The score of each variable within each component is in Additional file 1: Fig. S13
