Flume experiment started

Our first flume experiments started in November. We colonized biofilms under dark conditions and exposed them to nutrients with and without leaves. Preliminary results show that leaves stimulate heterotrophic P and N uptake.

Field sampling

Our field sampling in Lower Austria has started, comparing different headwater streams with and without riparian buffers and riparian forests. We investigated P uptake, P release, and respiration in the sediments.
