^*Soil temperature data available from on-site sensors previous to sampling.

^**Soil texture (sand, silt and clay), temperature during sampling, humidity, pH, organic matter (%), soil organic matter (SOM), total nitrogen (%).

^***Number of samples or replicates for which sequencing failed indicated in parentheses if applicable.

^†During 2012–2013 temperatures were not measured at the 1500, 1600 or 2000 m stations due to equipment failure.

e.r. Excluding replicates. 16S amplicon sequencing was however carried out for 7 replicates from 2014 taken at 2400 m.
