151 - Regarding the loss of dissolved organic compounds, if the first hypotheses is true, wouldn't it become apparent that algaes biomass does not increase in direct proportion with light levels, if light were the only altered variable? Does this same process happen with macrophytes?
154 - So does this page explain why we end up with a little hair algae near the base of large clusters of stem plants in the aquarium?
163 - What prevents algae from being temperature limited? Is a hotter tank (presuming it does not stress the plants) better for out-competing algae?
Overall I found the paper a more productive read than most of what I dig up. I'm going to give this paper a 2nd pass in a couple of days and see if I can't get my hands on some of the source studies they list.
Nice find, Tom.
