Cognitive: Knowledge of the fundamental structure and function of freshwater ecosystems focusing on the hydromorphological, chemical and biological elements required by the Water Framework Directive (2000/60/EC) for the evaluation and monitoring of the ecological status of freshwaters.                 

Affective: Awareness on protection and management of freshwater ecosystems.

Skills: Use of field polymeters, realise field sampling, perform species identification of phytoplankton, zooplankton and macroinvertebrate organisms, use of biotic indices, specialised software (for statistical analyses). Using bibliography, analysing, writing and presenting relative subjects (access to the electronic library of AUTH), working individually or in groups.

Teaching Methods: 

Lectures, laboratory and field work.

Course Contents: 

Lake and river origin. Geo-morphological characteristics. Physical characteristics (light, temperature, movement). Chemical characteristics (O2, CO2, ions + pH, nutrients, sulphur, conductivity, TDS, TSS, salinity). Organisms (benthos, plankton, nekton, macrophytes) and sampling methods. Food webs. Productivity. Pollution, biomonitoring, biological indices. Management. Legislation. Restoration.

Laboratory Exercises: 

1. Determination of nutrients (D. Bobori), 2. Phytoplankton (Μ. Moustaka), 3. Zooplankton (Ε. Michaloudi), 4. Macroinvertebrates (Μ. Lazaridou, Ε. Michaloudi, PhD and Master students), 5. Biological Indices (Μ. Lazaridou), 6. Statistical analyses (Μ. Lazaridou), 7. Written assignments concerning the ecological status of river and lake ecosystems (Μ. Lazaridou, Μ. Moustaka, D. Bobori, Ε. Michaloudi).

Υπαίθριες ασκήσεις:
