Our article „Dissolved Organic Matter Quality and Biofilm Composition Affect Microbial Organic Matter Uptake in Stream Flumes“ has been published in Water as part of the Special Issue „Transformation of Dissolved Organic Matter in Aquatic Landscapes“ and is available online:
Within the project „Organic Carbon ORCA“, a portable sensor for DOM fluorescence indices was developed. The paper is online now: „Brandl, M., T. Posnicek, R. Preuer, G.

The paper describes the effects of drying and re-wetting on the CO2, CH4 and N2O fluxes in the parafluvial zone of a restored floodplain channel. Enhanced biogeochemical turnover rates were identified during the intermittent period, when N2O and CO2 emissions peaked.
