| Abstract: | A model has been formulated which, when completed, will represent the main components and interactions believed to be important in the ecosystem of Lake Conway and other southeastern lakes as well. Information from both field work and literature surveys was used in formulating the model. The model as currently formulated requires better definition of nutrient-productivity relationships and of zooplankton population dynamics. Given simulated introduction of white amur, the model predicts decreases in phytoplankton, zooplankton, and herbivorous fish and increases in epipelic algae (i. e. that living upon the sediment), benthic invertebrates, and secondary predator fish, all for a 10-year period. The model also predicts a decrease in the quantity of sediments, which suggests a possible reversal of trend in the trophic state of the lake. However, these results may change with further refinement of the model. |
