| 520 | |a"Eutrophic hardwater lakes on western Canada's Boreal Plain are characterized by late summer cyano-bacterial blooms, hepato- and neurotoxin release during blooms, high macrophyte standing crop, and dissolved oxygen (DO) depletion that can kill aquatic organisms (S: Prepas, 1990; Kotak et al., 1993). These conditions have been at least partially induced by human activities such as land clearing for agriculture and recreational development (Allan et al., 1980; Mitchell & Prepas, 1990; Hall et al., 1999; Prepas & Serediak, 1999)"--Introduction. |
