Aquatic ecosystems: temperature, nutrients, light, wind, nutrient availability (especially p, sometime fe, water movement, upwelling (marine, turnover (lakes, water chemistry: salinity, ph, depth gradient, dark, cold, low productivity, nutrient accumulation. Friday, november 14, 2014: light, warm high productivity, when you are deep dark +cold, not very productive, more nutrients, when you are shallow light + warm, productive, limited by nutrient levels.
