From 20 to 24 April 2026, students enrolled in courses focused on hydrobiology, the ecology of non-native organisms, and biological invasions took part in a professional field excursion to Austria and Hungary. Among other sites, they visited the Biological Station of Lake Neusiedl, the Kis-Balaton wetland system, Lake Hévíz—the largest thermal lake in the world suitable for swimming—and the Balaton Limnological Research Institute in Tihany.
The excursion focused on the study of unique freshwater ecosystems and on issues related to non-native and invasive species. Students had the opportunity to observe a wide range of rare animal species and to become familiar with practical aspects of research, monitoring, and management of aquatic ecosystems. The programme concluded with a discussion on the risks associated with the introduction of non-native species through trade in live organisms.
For the participants, the excursion represented a valuable opportunity to link theory with practice and made a significant contribution to their professional development.
