Research groups

The basic task of the group is to study the taxonomy, population dynamics, feeding ecology, reproduction as well as community ecology of aquatic invertebrates. The studied objects are planktonic and benthic invertebrates, as well as aquatic and semi-aquatic insects. The profile of the research group includes the monitoring and impact assessment of the non-native invasive species, the assessment of the effects of anthropogenic disturbances on invertebrate communities, as well as chironomid-based paleolimnological research.

One of the main topics of the research group is survey structure and quantification of fish population in shallow water bodies of different trophy using hydroacoustics. The aim of the bioacoustic reearch is to establish ecological rehabilitation of eutrophic waters. As a first step toward ecological restoration, the research group applies the hydroacoustics as a new technique first time in Hungary aiming at measuring the population dynamics, the structure of fish communities, size frequeny distribution, stock abundance and biomass.

The core of the research program of the of Chemical ecology and Neurobiology Research Team is the analysis in invertebrates, mainly in mollusks, of chemosensory processes, interactions as well as the processing of chemical stimuli originating from the surrounding. All these aim to reveal the chemical ecological aspects of animal-plant and plant-animal interactions.

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 ...

The primary scope of the department is the exploration of river ecosystems, mechanisms, biological funcions and long term dynamics of their animal communities (zooplankton, macroinvertebrates, fish), especially the impact of landscape management, water utilization, river regulation and other human activities inducing also polarized light pollution, as well as the establishment of the scientific basis for the restoration and conservation of river ecosystems.

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.

We investigate how changing climate and land use affect vegetation in the sand region of Kiskunsag, Central Hungary. Research topics include the ecological effect of warming, drying, wildfires, and plant invasion, as well as succession following land abandonment and following the removal of alien tree plantations. Approaches range from descriptive local case studies and long-term monitoring, through lanscape and regional-scale surveys, to complex field experiments.

The Forest Ecology Research Group investigates the biodiversity, species and functional composition, pattern, history, dynamics and function of forests. The research is mainly focused on the temperate deciduous forest zone of the Carpatian Basin including unmanaged and managed forest stands.
