Research interests of the Laboratory of Hydrobiology are related to studies of freshwater ecosystems in Latvia. The main research topics are:

  • complex hydrochemical and hydrobiological studies of Latvian rivers, lakes, and reservoirs;
  • studies of biodiversity and its long-term changes in freshwater ecosystems;
  • eutrophication of freshwater ecosystem, changes in flows of nutrients and organic matter.

Researchers have elaborated and intercalibrated national methods for the ecological quality assessment of lakes and rivers according to the requirements of the EU Water Framework Directive.

Teaching at the University of Latvia

Laboratory staff is teaching students at the Faculty of Biology and Faculty of Geography and Earth Sciences. They are advisors and reviewers of Bachelor, Master and PhD thesis.
