Aquatic Macroinvertebrate Research Group
The research group conducts basic and applied ecological research in aquatic and wetland ecosystems on macroscopic aquatic invertebrates.
Our basic research is related to the following specific topics: investigating the overall taxonomic, functional and phylogenetic diversity of aquatic communities, exploring the causes of changes in diversity profiles at different spatial scales. Determining spatial and environmental factors in community assembly in aquatic ecosystems. Impact of climate change induced droughts on community organisation. Investigating the role of dispersal in the taxonomic, functional and phylogenetic composition of aquatic communities in response to environmental factors altered by climate change. Assessment of distribution areas of macroscopic aquatic macroinvertebrate species of European importance using different climate scenarios.
In addition, we systematically and continuously carry out zoological surveys of the Tisza River Basin. With these baseline studies we are making a significant contribution to reducing the knowledge gap on various aspects of biodiversity that has made it difficult to conduct comprehensive analyses so far. Zoological surveys and mapping will greatly facilitate the early detection of invasive species and the monitoring of their spread as well.
We conduct our applied research primarily in line with the EU Water Framework Directive. From a societal point of view, it is important to study the impact of pressures on surface waters, and we analyse the individual and synergistic effects of pressures on the taxonomic, functional and phylogenetic composition of aquatic communities. For vulnerable waters (e.g. saline and small drying water bodies), we are developing more effective biotic indices to support ecological water quality assessment, which will allow a more accurate assessment of the ecological status of our socially important waters. In the urban environment, we monitor wetland habitats and carry out awareness-raising activities in line with our research activities.
