Augustinus Liechtenstein successfully defended his Master thesis "Phosphorus adsorption capacities of stream sediments in Lower Austria with relation to land use and riparian vegetation" under the supervision of Gabriele Weigelhofer at BOKU on Nov 16, 2022. His work was conducted at WasserCluster Lunz and studied the effects of riparian forests on the phosphorus uptake potential of stream sediments. We congratulate warmly.
