The Dominance of Cyanobacteria in Ponds of the Hudson Bay Lowlands and the Limiting Factors to their Growth
Seventy and thirty four Churchill ponds were surveyed for physical, chemical and algal data during July 2012 and July 2013, respectively. The physical results confirm that these ponds vary widely in surface area due to different pond origins. Mean pond depth values confirmed that these ponds are sha...
