The Theory of Island Biogeography Says That the Number of Species

question 18

Multiple Choice

The theory of island biogeography says that the number of species on an island of a given size will stay fairly constant over time. How did the Simberloffs test this using mangrove islands in Florida, and was the theory supported?

• A) They counted all the insects on a group of islands over time and the numbers didn't change so the theory was supported.
• B) They removed all the insects on a group of islands and then monitored how many came back. Before and after numbers were similar, so the theory was supported.
• C) They removed all the living species on a group of islands over time and monitored how many came back. Before and after numbers were similar, so the theory was supported.
• D) They removed all the insects on a group of islands and then monitored how many came back. Very few came back, so the theory was not supported.
• E) They physically isolated a group of islands and then monitored all the species over time. The numbers changed quite dramatically so the theory was not supported.
