    John Horne commented on "Approximately how many coral reef associated marine invertebrate species are widespread across the tropical Indo-Pacific?":

    To answer Barbara's question, the size of a species geographic range is a biological feature of importance. Generally, species with large geographic ranges and high dispersal are expected to be less likely to go extinct than species with small geographic ranges and low dispersal. The fossil record of marine invertebrates, such as mollusks and corals that leave behind durable remains, supports this idea. As we look forward to the future, and the gradual demise of coral reef ecosystems understanding the factors that determine species ranges and dispersal are going to be highly relevant to conservation efforts, and to evolutionary ecology.
