The Ngāi Tahu Research Centre invites you to attend its October seminar with Tara McAllister presenting: Formidable Phormidium: Toxic algae in Canterbury Rivers.

When: Thursday 13 October, 2.30pm – 3.30pm
Where: Room 208, Level 2, Te Ao Marama Building, University of Canterbury

Toxic algal blooms, in both lakes and rivers, are a major concern in many countries due to their increasing extent and severity. The particular species Tara studied is called Phormidium and proliferates in many of our Canterbury rivers. Phormidium can produce powerful toxins, posing a significant health risk, Phormidium inadvertently affects the ecology and health of rivers.

Tara sampled eight different Canterbury rivers in order to elucidate the effect of different environmental factors, like river flow and water temperature, on growth. Tara manipulated nutrient and flow conditions in experimental river channels to see how these changes would affect growth.

These experiments will help us begin to think about how Phormidium is likely to respond with increasing agricultural intensification. The results of these two studies will be presented and discussed.
