This model is an agent-based population genetics simulation. The program contains the tools to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).
LAB
This model simulates MacArthur & Wilson's 1963 Island Biogeography Equilibrium paper. You can run virtual experiments manipulating the following: island size, distance from mainland, habitat type, and species types (e.g. birds, arthropods, etc.).
LAB
This model is a simulation which draws upon Gauss' (1934) classic experiments with protists. In this virtual petri dish, you can add bacteria, two species of Paramecium, and a predator. The two Paramecium (P. aurelia & P. bursaria) species compete for resources.
LAB
As the name suggests, this model simulates the foraging behavior of two predator species. Predators forage and gain energy from prey while using energy to move. The model tracks the mean and standard deviation in energy for each species.
LAB
This model illustrates resource-limited population growth. Populations have a per-capita growth rate and carrying capacity. Two populations are compared on three graphs: N vs time, dN/dt vs N, and dN/Ndt vs N.

LAB
This model simulates the classic example of natural selection on color patterns in peppered moths (Biston betularia). When air pollution is low, lichens cover the trees and the light moths are well camouflaged. When air pollution is high, the trees become dark and the light moths stand out.

Knowing how many individuals are in a population can be critical. How can you tell how many there are when there are too many to count? This model simulates a pond of tadpoles. The population size can be estimated in three ways: direct sampling, sampling with removal, and mark/recapture.
LAB
Many animals are at risk of being eaten by other animals. Such an animal must balance food intake with predation risk. These models simulate Pulliam's (1973) vigilance model, which suggests that feeding in flocks is advantageous. Individual - Individual parameters can be adjusted.
