Description:

Individual-based population models are being increasingly used to predict the consequences for populations of environmental stress on individuals. This project aims to test the fundamental assumption behind individual-based modeling; namely, that a population may be modeled as a collection of individuals growing, reproducing and dying in accordance with the same rules that were previously determined and tested for isolated individuals. The research will involve the use of modeling to generate predictions, and experiments on laboratory populations of Daphnia to test the predictions. The project is a crucial part of a larger program that aims to develop methods for predicting the effects of exposure to toxicants, and other human-induced perturbations, on the dynamics of ecological systems.
