Title Amount of Redistributed water
Downloaded 5 times
Description Amount of redistributed water from chamber I to chamber II based on hydrogen stable isotope analyses (isotope mass spectrometer: delta V advantage, Thermo Fisher Scientific) of extracted water from collected soil samples of chamber II after deuterium-labeling of chamber I. Data is in relation to time after rewetting of chamber I and from all mesocosms of HR as well as control treatments (data used in Fig. 1).

Title Carbon dioxide production rates
Downloaded 9 times
Description Carbon dioxide and 13C-CO2 production rates based on efflux measurements using a infrared gas analyzer (LiCOR 820, Licor, USA) and an elemental analyzer (NA 1108, CE Instruments) – isotope ratio mass spectrometer (delta S, Finnigan MAT) linkage, respectively. Data is in relation to time after rewetting of chamber I and from all mesocosms of HR as well as control treatments.

Title Cumulative carbon mineralization of labelled plant material in chamber II
Downloaded 7 times
Description Cumulative carbon mineralization of labelled plant material in chamber II interpolated from measured 13C-CO2 efflux values (see also Carbon dioxide production rates.csv). Data is in relation to time after rewetting of chamber I and from all mesocosms of HR as well as control treatments.

Title Enzyme activity rates on soil surface of chamber II
Downloaded 10 times
Description Enzyme activity rates of N-acetylglucosaminidase (NAG) and cellobiohydrolase on soil surface of chamber II. Enzyme activite was measured using soil zymography with fluorogenic 4-methylumbelliferone-substrates. Data is in relation to time after rewetting of chamber I and the postion on the surface of chamber II (from 1-4 with increasing distance to the air gap). Values are given for all mesocosms of HR as well as control treatments.

Title Volumetric water change in chamber II
Downloaded 6 times
Description Volumetric water change in chamber II as monitored by soil moisture sensors (ECH2O-10 moisture sensors, Decagon Devices Inc). Data is in relation to time after rewetting of chamber I for all mesocosms of HR as well as control treatments.

Title Water potential of soil samples from chamber II
Downloaded 8 times
Description soil water potential ( as pF value) measured on collected soil samples from chamber II using the chilled mirror dewpoint method (WP4-T, Decagon Devices Inc.).Data is in relation to time after rewetting of chamber I and distance to the air gap (1=0-6.66 cm; 2= 6.66-13.33 cm; 3=13.33-20 cm). Values are given for all mesocosms of HR as well as control treatments.
