| Summary: | This dataset consists of measurements of leaf and root growth, species abundance and soil temperature made in ten subarctic plant communities located at the Arctic Biosphere Atmosphere Coupling at Multiple Scales (ABACUS) project sites near to Abisko, Sweden, and Kevo, Finland. The data were collected during the summer growing seasons (May to September) in 2008 and 2009, and comprise field survey measurements, temperature logs and values derived from analyses of mini-rhizotron images. ... : At each field site, eight replicate 1 x 1 m plots were established in five subarctic vegetation communities representative of the wider landscape, including birch forest, forest margin, tall and dwarf shrub tundra communities and sedge lawns. Each plot had a mini-rhizotron (0.3x0.7 m length of 70 mm diameter clear acrylic tubing) installed at 45o and shoots of the dominant plant species tagged with numbered cable ties. In 2008 in Kevo and 2009 in Abisko, length of all tagged shoots was recorded approximately weekly during the growing season, and a weekly 360o scan of all mini-rhizotrons taken with a CID-600 root scanner (CID Bioscience, Camas, Washington, USA). Root length was obtained from the scanned images by manually digitising visible roots using MapInfo Professional v. 8.0 software (Pitney Bowes Business Insight, New York, USA). Percentage cover of all species was estimated once at peak biomass in early August by a single surveyor, using a 0.75 x 0.75 m quadrat placed over each mini-rhizotron. Soil ... |
