FACTORS CONTRIBUTING TO THE PROLIFERATION OF THE TOXIC COASTAL BLUE GREEN ALGA, LYNGBYA MAJUSCULA

Increasing occurrence of blooms of the harmful blue green alga Lyngbya majuscula in Queensland coastal waters has led to detailed investigations into the factors contributing to these blooms. While appropriate temperature and light regimes are critical, increased inputs of terrestrial organic matter and the trace nutrient iron appear to be major factors contributing to increased growth of this organism. Organic leachates that are strong ferrous iron complexants appear particularly facile in stimulating algal growth. In addition to investigations of the physiological response of Lyngbya majuscula to changes in solution chemistry, we also report on the results of genetic studies of this organism.
