Biogeography

Based on the theory of island biogeography, which of the following is the most likely reason that an island in the ocean that is 5 kilometers from a continent would have a higher number of species than one that is 15 kilometers from a continent?

• There are more species that have the ability to travel 5 kilometers than can travel 15 kilometers.

• Islands that are closer to continents always have a wider range of habitats than more distant islands do.

• There are smaller populations of each species on islands that are at greater distances from continents.

• Islands that are closer to continents always have more ecological niches than more distant islands do.

What prediction is correct about island biogeography?

• Smaller islands have more resources, and will have more biodiversity

• Larger islands have more space for resources, but will have less biodiversity due to competition

• Islands closer to mainland will be more diverse due to more successful dispersal.

• There is more diversity far away from the mainland because some species fly.

Why do small, isolated islands have a faster rate of species extinction that larger, less isolated islands?

• Small remote islands have more available resources.

• Small remote islands have less available resources.

• There is typically greater genetic diversity on small remote islands.

• Small remote islands typically experience greater migration rates.
