Model 1 – Island Biogeography
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.).
Directions and background information are embedded in the model exercise.
This model is loosely based on the water quality monitoring procedure of the Save Our Streams project of the Izaac Walton League of America. The underlying premise is that water quality affects the biodiversity of a stream. Thus, surveying the macroinvertebrates in a stream is a way to indicate water quality.
This model simulates plants present in two habitats that are separated into a southeast-facing xeric slope and a northwest-facing mesic slope. These species represent wildflowers common to the southern Appalachians, with some being more characteristic of mesic habitat, others more characteristic of xeric, and some that may be found in both. With this model you can set up different sampling protocols to compare and contrast the biodiversity of the two habitats.
