Presentation Transcript

  1. Effects of Cyanobacteria State of Science Paper Illinois State University Geology – Hydrology (361)

  2. Outline • Purpose • Background / Thesis • Spreading • Factors (Harming) • Conclusion

  3. Cyanobacteria

  4. Purpose • How does cyanobacteriaspread? • What does cyanobacteria harm/kill? • Thesis purpose – Treated?

  5. Location

  6. Hydrology • Temperature • Samples – Total nitrate, phosphorus, nitrogen, ammonium, phosphate • Ion Chromatography • Dissolved Oxygen • Conductivity • Flow cam

  7. Summer of 1996 • Five weeks • Zooplankton and Cyanobacteria • Temperature 20 degrees Celsius • Added Nutrients • Depths • Shallow (2m) • Deep (5m)

  8. Summer of 2003 Figure 2. Nutrients added (Nitrogen & Phosphorus)

  9. Summer of 2003 • Amsterdam, Europe • Mixing of the water depths • Hottest Summer • Common type of Cyanobacteria • Family of Toxins • Harmed/ Killed

  10. Sunlight • Growth of bloom • Eggproduction • Daphnia • Two types of toxins • Alkaloid neurotoxin (A. flos-aqua) • Nucleosides (A. affinis)

  11. Daphnia vs. Anabaena(Zooplankton) (Cyanobacteria) Figure 3. Survivorship vs. Days

  12. Toxins Alkaloid Neurotoxins Nucleosides Animals and Humans Anorexia Weakness Vomiting Diarrhea • Domestic & Wild • Muscle fatigue • Staggering • Gasping • Convulsions • Death – Hours later due to respiratory matters

  13. China • Cold environments • November • Water column • January • Summer • Start of summer • Tests done

  14. Conclusion
