Interacting particle systems, a vigorous area in probability theory, have a structure that makes them appropriate to the development of ecosystems. Their use as models is impeded by the fact that the mathematical theory is not easy to read and understand. To bridge the gap between theory and applications the project will develop software to allow biologist interested in using these models to learn about existing results and to simulate and analyze their own models. ***
