Another flume experiment, this time with a day-night-cycle to stimulate algal growth
Finally, after almost one year delay (waiting for an opportunity to meet in person), we had an online kick-off meeting on February 10. At least, we could look at the first results of 2020 and plan the sampling and the experiments accordingly for 2021.
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.
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.
Due to the Covid situation, we had to postpone our field work to summer. We keep you informed
