At first I was mildly confused by the layout and look of the thing; it took me a minute to figure out that these are lecture notes. A lot of it doesn't apply to our situation, but I did find the part on competition interesting. I think I may have to put Tilman’s book on the subject of resource competition on my list of eventual purchases.
There's more lecture notes from the same class here: Limnology
Some of the other lecture topics seem hit and miss. I'd probably glaze over during the phosphate = algae lectures, and try to shake it out of my head after. If I were a student, I'd also want to know why there needs to be 4-5 lectures on the evils of humanity, but none on the processes involved with a lake naturally meeting its end.
