Seedlings were grown in soil collected from an experiment at Hambleton Forest, North Yorkshire. Soils originated from plots containing either Scots pine or birch monocultures, or a mixture of both species. In the lab, pairs of seedlings of birch and Scots pine were grown as monocultures and mixtures from each of the three plot treatments. The data represent the biomass, leaf C:N ratio and mycorrhizal status determined after 20 weeks.

Data comprise soil microbial and biogeochemical data collected during a snow manipulation experiment on the summit of Hohe Mut (2650 m) near Obergurgl, in the Austrian Alps (lat. 46.84862, long. 11.02957). Soil microbial data include phospholipid fatty acid (PLFA) analyses, and bacterial (16S Small subunit ribosomal RNA) and fungal (internal transcribed spacer region 2) high throughput sequences. Soil biogeochemical data include soil extracellular enzyme activities, soil pH, gravimetric moisture content and various C and N pools and fluxes. The experiment was part of the NERC project NE/N009452/1. Full details about this dataset can be found at https://doi.org/10.5285/255320dd-38ae-4a07-93bb-4f90439309f8

Data comprise soil microbial and biogeochemical data collected during a climate and vegetation change experiment conducted across three valleys in Tyrol, in the Austrian Alps. Sites were located near the villages of Obergurgl (lat., long. = 46.844833, 11.023783; mean elevation = 2279m), Soelden (46.978367, 10.972217, mean elevation = 2469m) and Vent (46.863217, 10.896800, mean elevation = 2472m). Soil microbial data include phospholipid fatty acid (PLFA) analyses, and bacterial (16S Small subunit ribosomal RNA) and fungal (internal transcribed spacer region 2) high throughput sequences. Soil biogeochemical data include soil extracellular enzyme activities, soil pH, gravimetric moisture content and various C and N pools and fluxes. The experiment was funded by NERC project NE/N009452/1. Full details about this dataset can be found at https://doi.org/10.5285/977c422d-8529-432d-85d7-5de3c8dfdc5d

Data comprise numbers of soil microarthorpods (mesofauna) extracted over 10 days from soils in northern, subarctic Sweden sampled on 29th July 2019. Soils were sampled from treeline mountain birch forest and stands of tundra willow that were wither 'girdled' (connection between leaves and roots cut by disrupting the phloem transport) or ‘control’ (no treatment), two years prior. Full details about this dataset can be found at https://doi.org/10.5285/d3c98f24-7a4d-40b8-989a-6cc340e91cac

Fungal community DNA was sequenced from soils in northern, subarctic Sweden. Soils were sampled from treeline mountain birch forest and stands of tundra willow that were wither ‘girdled’ (connection between leaves and roots cut by disrupting the phloem transport) or ‘control’ (no treatment), 0, 1 and 2 years after the treatment was applied.
