2. Both Cedar and Parramore Islands are shrinking due to erosion of the sand, a typical characteristic of barrier islands that is being accelerated by human interference Cedar Island has lost Ikm of its southern coast in the last 20 years while Parramore's coast has only changed by a few meters. Predict how this change will impact the diversity on the two islands, linking your response to island biogeography theory,
There are a number of barrier islands along the Atlantic coast of the Delmarva peninsula. In particular, many of the islands of the Virginia coast are truly Isolated from the mainland, Cedar, Parramore, Hox Cobb and Wreck Island are five that vary in size and distance from the main shore, The figure to the left depicts the islands, Cedar Cedar and Parramore Islands are approximately the same size - 8 sq, miles, Hog Island is only slightly smaller, 7 sq mi and Cobb (4 sq mi) and Wreck (2.5 sq mi) are the smallest. Parramore Cobb Island is only slightly farther (7.5 mi) than Wreck Island (7 mi) from the mainland. The other 3 Islands have some marsh and wetland that makes them closer to land. Hog Island is 5.5 miles away from any land, Parramore 3.25 mi, and Cedar only I mi. Hoz J Cobb & Wreck 1. What is the expected level of species richness at equilibrium for each island? Rank them from most to least rich. Use a diagram of immigration and extinction to support your answer.
