Name of the researcher(s) and research group:

  • Dr. Sándor Szabó
  • Gergő Koleszár

Name of the Institute:
University of Nyíregyháza, Institute of Environmental Science

Research objectives:
The aim of the project is to find those potential key factors that sustain the stable dominance of submerged vegetation against floating plants.

Description and results of research:

Submerged vegetation contributes to clear water state with high biodiversity and good water quality, on the other hand free-floating plant dominance leads to anoxia with low water quality. Both vegetation types are able to sustain alternative stable states. In laboratory experiment and in large scale field survey we examine the competitive interactions between them and how they can sustain their stable state against each other during eutrophication. Result contributed to overall knowledge for the conception of sustaining clear water state in freshwater ecosystems.
