Research Interests

Avital Gasith’s interests lie in  freshwater ecology, conservation and rehabilitation of aquatic systems (stream pollution and rehabilitation, structure and function of the littoral zone in lacustrine ecosystems, conservation of rain-pool ecosystem). His research includes the role of flooded shore vegetation in the ecology of Lake Kinneret (fish reproduction), the impact of stone quarrying on the ecosystem of dryland Negev streams, integrating road runoff in roadside ecosystems, restoration of abandoned  agricultural land (creation of a community nature park by restoring native vegetation and construction of a rain-pool). He is Head of the Environmental Studies Master’s Program (Porter School, TAU). 


Specific research interests include:  

  • Stream ecology, health, pollution and rehabilitation
  • Structure and function of littoral zone in lakes
  • Aquatic conservation (streams, rain pools)
  • Amphibia studies
