Populus

http://www.cbs.umn.edu/software/populus.html/

The Populus software contains a set of simulations that we use to teach population biology and evolutionary ecology at the University of Minnesota. Simulation models are chosen from menus, and students can move among the parameter boxes of an input window, changing initial defaults to values of their own choosing. Most modules offer several graphical outputs of model dynamics, and all provide help screens explaining the computational algorithms.
