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.
Our focus is on the relationship between environmental pollution and health problems according to the following major points:
1. Screening-level risk assessment of pollutants (SLRA), with special reference to heavy metals, polycyclic aromatic hydrocarbons and polychlorinated biphenyls. The use and drawing up proper site models to identify pollution sources, pathways and fate of contaminants of potential concern.
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 research group basically investigates the cycling of the macro elements (Carbon, Nitrogen, and Phosphorous). One of the main goal is to determine the effect of internal and external nutrient loading and water level fluctuations on the water quality of Lake Balaton. The concentrations of different compounds of nitrogen and phosphorous are regularly measured in the water column and sediments of the Lake. Their uptake are determined with labelled nitrogen (15N) and phosphorous (32P), the competition of bacteria and algae for nutrients are investigated in cultures and in situ experiments.
The group studies the distribution, diversity, dynamics and ecophysiology of phytoplankton in Lake Balaton and other lakes with particular emphasis on extreme habitats. Besides nano- and microplankton, the picoplankton constitute the focus of the research, which are studied with traditional methods as well as fluorescence and molecular biological tools. . . .
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.
