The Theory of Island Biogeography Directions: Part 1: Control run 1) First, you will run the models when both islands are the same diameter (256km) and the same distance from the mainland (10km). Always uses the arthropods. Write a prediction before you run the model: do you believe the number of species will be the same on each island? Why or why not? If the two islands are the same diameter and distance away from the mainland, then the number of species on each island won’t be the same because even though the dimensions are the same the number of species won’t be the exact same. 2) Under run hit “go.” Run the simulation until the time reaches at least the 1000 mark. Then hit the “go” button again to stop the simulation. Record the data in the table below 3) Did your data align with your prediction? Explain. The data aligned with my prediction since even though the number of species between the two islands is similar, the number of species was not the same. Part 2: Island Distance 4) Under Island variables, increase the distance of Island 1 to 410km. Write a prediction before you run the model: Which Island do you think will have a greater number of species? Explain your reasoning.
