CO2 efflux, root and mycorrhizal hyphae production in subarctic willow shrub and treeline birch forest, Abisko 2017-2018
This dataset contains in situ CO2 efflux, root production and fungal hyphae production from plots distributed across a subarctic landscape in Northern Sweden. Six paired plots were established in mountain birch forest and five paired plots were established in tall shrub tundra where one of each pair was 'girdled' and one acted as a non girdled 'control'. Efflux measurements were made during six sampling campaigns over 2017 and 2018 at an approximate frequency of once per week during each campaign, constituting a time series of measurements. Production measurements integrated root or hyphae production over the whole growing season (June-September) and therefore there is one datapoint per plot per year.

Efflux data were generated using a infrared gas analyser in closed system mode which measures the linear increase in CO2 concentrations over a 2 minute period. Root ingrowth was measured by inserting root-free peat in a container with 2 mm mesh openings into the ground in June and extracting in September, the in-grown roots were picked out, washed, dried and weighed. Hyphae ingrowth was measured by inserting a bag with 35 um openings filled with washed sand into the ground over the same period of time as the root bags. Sand was extracted from bags and immediately freeze dried. The sand was then sonicated and the hyphae were extracted and ingrowth carbon was compared with lab black controls.
