Brief description of the main scopes: 

I am doing research on ecological physiology of aquatic plants in freshwater environments. My research focuses on the influence of biotic and abiotic factors on growth, production and distribution of macrophytes. I work with effect of nutrients, light environment of water on submerged-emergent macrophytes. Interested in interclonal, interspecific competition of macrophytes. Work with phenology of macrophytes, as well as with all aspecty of phenotypic plasticity. Interested also in morphological and physiological variability of native and invasive macrophytes.

Mostly studied species:

  • Phragmites australis
  • Potamogeton perfoliatus
  • Myriophyllum spicatum
  • Ludwigia grandiflora
  • Trapa natns
  • Nelumbo nucifera
  • Nuphar lutea


Main profile in keywords: 
ecological physiology of macrophytes; interaction of macrophytes with algae, bacteria; plant phenology; inter clonal competition, variability; phenotypic plasticity; morphological and photophysiological processes
