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. Thus during my studies I worked with effect of nutrients, light environment of water on submerged macrophytes. Interested in interclonal interspecific competition of macrophytes, and within plant morphological andphysiological variability and its ecological and evolutional significance.

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, macrophyte periphyton interaction, inter clonal competition, within-plant variability, effect of nutrient availability, optical properties of water, wave impact on morphology and photophysiological processes
