Research groups

We examine the biodiversity and assemblage organization of freshwater fish and macroinvertebrates. Our primary model system is Lake Balaton and its catchment, which is affected by a variety of human impacts. The primary focus is to explore the environmental drivers of population dynamics and assemblage organization.

The group studies the distribution, diversity, dynamics and ecophysiology of phytoplankton (nano-, micro- and picoplankton) in Lake Balaton and other lakes with particular emphasis on extreme habitats.

The main objective of the group is to study ecological communities. We focus mostly on freshwater macroinvertebrates. We examine the effects of human impacts on freshwater biodiversity. We deal also with the methodology of community ecology. We are interested in approaches quantifying community-level phenomena

- Chemical characterization of aquatic environment (water body, sediment, phyto- and zooplankton, phyto-and zoobenthos, macrophyton, macro invertebrates, fish) with special attention to the exploration of pollution sources and identification and quantification of pollutants (e.g. pharmaceutical residues, microplastics)
- Monitoring of water quality in rivers and lakes complying with the requirement of the EU Water Framework Directives and database building to follow the changes of physical, chemical and biological parameters of Lake of Balaton as well as Duna and Tisza rivers

A basic task of the team is the monitoring of the zooplankton and littoral invertebrate communities in several different standard sampling sites of Lake Balaton. This activity serves the continuous enlargement of the long term datasets concerning to the species composition, individual density, biomass and production of the zooplankton and macroinvertebrates dvelling the littoral zone.
