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 primary task of the research group is to study the structure, biological functions and long-term changes of the aquatic ecosystems and their communities (zooplankton, macro-invertebrate, fish, amphibian, reptile, waterbird) especially regard to the Danube and Tisza River valley ecosystems.

Conducting research on planktonic and benthic algae, studying the effects of dynamic water regime, hydrological events, local and global disturbances and climate change.

We apply a variety of ecological methods to study species, habitats, landscapes and ecosystems of conservation importance.

Fundamental and applied research on aquatic macrophytes and biofilm developed on plant surfaces with special focus on:

The department surveys the biodiversity in the different habitats of the Tisza River, the eleventh longest river in Europe, and in the connected wetlands of its catchment area, investigates the tolerance thresholds of the biota under extremely variable environmental conditions, and explores the role of the tributaries, connected ox-bows, canals, and the hyporheal in the regeneration of the fauna and flora especially following pollution events and flood waves.

Wetland Ecology Research Group conduct systematic ecological surveys on wetlands. We are basically interested in the process of community assembly in aquatic and semi-aquatic habitats. We do fundamental researches that aim to explore species distribution, autecological characteristics and species interactions. We give high importance to implement the results of fundamental studies into practice. Therefore, we address questions having relevance in restoration ecology and socio-economy (e.g. Water Framework Directive).

- 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

Development and management of IT applications, databases and web tools for ecology, botany and nature conservation. Contribution to developemtn of Biome-BGC ecosystem modeling and perform simulation runs. Modeling energy flow, carbon and nitrogen cycling of forest ecosystems.

Long term monitoring of strict forest reserves focused on stand structure, shrub and understorey layers. See: Homepage of Forest Reserve Programme.
