Contents of the course

PART A. THE BASICS AND THE BASIS

  1. ALGAE – GENERAL
  • Primary production in freshwaters
  • Algal phylogeny
  • Characteristic features of algae
  • Periphyton: distribution and adaptations
  1. ASSESSING THE ALGAL BIOMASS AND THEIR EFFECTS IN THE RIVER
    ECOSYSTEMS
  • Sampling benthic algae
  • Sampling phytoplankton
  • Regularities in the biomass values
  • Nutrient relationships to biomass
  • Associated problems to the massive growth of algae in fluvial systems. Some case studies
  • Implications of massive algal growths for ecosystem functioning
  • Geosmin production
  1. ALGAE ECOLOGY
  • Making up the energy budget: the primary producers
  • Making up the energy budget: the primary producers
  • Environmental factors affects affecting algae-light
  • Environmental factors affects affecting algae-nutrients
  • Factors regulating primary production: light and nutrients
  • The relevance of water flow and thickness for algae
  • Environmental factors affects affecting algae –salinity and pH
  • Biological factors affects affecting algae: grazing
  • Environmental and biological factors affects affecting algae: summary
  • The “River Continuum Concept”
  • Measuring primary production
  • Measures in situ
  1. ALGAE TAXONOMY
  • Cyanobacteria
  • Dinophyta
  • Cryptophyta
  • Euglenales
  • Diatoms
  • Green algae
  • Chrysophyceae
  • Xanthophyceae
  • Rhodophyta
  • Phaeophyta

PART B. DESIGN AND APPLICATION OF ECOLOGICAL INDICES
– The definition of ecological indicator
– Diatoms as ecological indicators
– The use of algae and indicators of ecological quality
– Algae and environmental policy
PART C. PRACTICING THE USE OF ALGAE AS ECOLOGICAL INDICATORS
– Sampling methods
– Practicum: collection and analysis of algal samples, and confection of an
ecological index.

  • Field sampling: collecting plankton and periphyton samples in Can Tho river and in fish tanks
  • Lab work: recognize algae under microscopy for genera identification
  • Final report: conducting results of the river water quality base on the algae status and the application of an index

Certification: at the end of the course, most of participants were awarded a certificate certified his/her participation of the course.
