This is an updated version of an existing lab. It includes some theoretical background information and the lab which simulates MacArthur & Wilson's 1963 Island Biogeography Equilibrium paper.

This is an updated version of an existing lab. It includes some theoretical background information and the online lab which models Connell's 1961 classic competition experiment. Students can explore the fundamental and realized niches of two species of barnacles, Chthamalus and Balanus.
LAB
This is an updated version of the existing lab. It includes some theoretical background and the online lab, which allows students to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).

This simulation visualizes the process of diffusion accross a semipermeable membrane and helps to explore the role of this phenomenon in body functioning.

The number of individuals in a population, or population size, is perhaps the most important thing to know about a population.

Garrett Hardin (1968) described how multiple individuals acting in their own interests, while exploiting a common resource, will inevitably overexploit the resource. This model illustrates the concept in a common field where four farmers are grazing cattle.
LAB
This simple model simulates seining a stream for animal life. Sixteen species of;invertebrates wash down the stream. When the seine is open they may get caught and separated into buckets.
LAB
This model simulates Endler's 1980 classic experiment on the balance of sexual selection and natural selection. In guppies, females prefer to mate with males that have lots of spots, but those males are more easily seen by predators.
LAB
This model is an adaptation of the classic experiment conducted by Peter Buri (1956), which documented genetic drift in laboratory populations of Drosophila.
