Some of the models use environmental stochasticity in the calculations. I found out that this has to do with random variables. This program is obviously meant for use in education and research. It's not your everyday, let's have-fun-with-science project.

Features include:

• Geometric growth graphs
• Help files with explanations of equations and variables, and example runs for some of the models
• A logistic model with an environmental stochasticity parameter

The radio buttons that set which graph to display sometimes need to be selected twice in order to change the graph display.
