Behavior of simple closed ecological systems; lower nutrient concentrations allow longer persistence of grazer populations

Abstract: caused by greater algal photosynthesis and the lack of exchange with the atmosphere. Replicate variability that used small Daphnia suggested that inadequate grazing capability allowed algae to create conditions unfavorable to Daphnia survival. Over months, algal and Daphnia abundance decreased, presumably because of inadequate nutrient recycling; these populations increased temporarily after the addition of nutrients. The addition of natural lake organisms did not increase the nutrient-recycling capabilities of the systems. Understanding the mechanisms of closed systems will be useful in implementing biological processes in managing life support systems.
