"A phosphorus enrichment experiment was run in flow-through troughs at Hinton, Alberta to examine taxonomic, growth and biomass responses by periphytic algae to P04-P additions in the Athabasca River. A standard test for nutrient deficiency showed that growth of algal periphyton was limited by phosphorus. More detailed growth and biomass responses to P additions were examined at P04-P additions of 0 (control), 0.1, 0.2, 1, 5, 10, 25 and 50 ugL-1 applied to randomly selected troughs from which tile and silt substrata were sampled to measure the time-course accrual of chlorophyll a. In unamended river water, the algal community was dominated by diatoms on both substrata but at P concentrations %5E1 /ug-L'1, the green alga, Chlorella sp. became the most abundant single genus on tile, comprising almost 70% of total cell numbers"--Report summary.
