You're analyzing biodiversity on three islands: Island A, located near the equator with varied elevations; Island B, situated in temperate latitudes and relatively flat; Island C, another equatorial island but with a wide variety of habitats. To test your answers to the first question, you decide to survey the lizard species on the islands. Below is a graphical representation of a survey plot from each island, where icons represents different species and the abundance of each species is tallied in the table below. (note: these surveys may not represent the entire island patterns, so don’t use these to try to answer the first question!) A. What is the alpha diversity on each island? Island A Island B Island C B. What is the beta diversity between each island pair (A-B, A-C, B-C)? Beta diversity A-B Beta diversity A-C Beta diversity B-C C. Calculate the Shannon-Weiner index and Simpson’s index of diversity for each island. Island A Island B Island C D. What do these diversity metrics tell you about biodiversity on each island?
