Fig. 2. Variance partitioning from the PERMANOVA of prokaryote and fungal community composition, overall, across elevational gradients, and among master horizons (lack of samples in the C horizon prevented analysis in this layer).

Climate is the combined effect of mean annual temperature and precipitation. Soil chemistry is the combined effect of pH (1:2 CaCl₂) as well as the concentration of total extractable aluminum, calcium, carbon, iron, magnesium, nitrogen, phosphorus, potassium, silicon, and sodium (mmol kg⁻¹).
