Describe what happens during the bottleneck effect.

• A population size is increased because of an environmental event. This increases the genetic variation and can increase biodiversity.

• A population size is reduced because of an environmental event. This reduces the genetic variation and can lead to a loss of biodiversity.

• A population size is reduced because of an environmental event. This increases the genetic variation and can lead to greater biodiversity.

The Theory of Island Biogeography states that

• There are more species on islands that are smaller and farther from the mainland.

• There are more species on islands that are smaller is

  and closer to the mainland.

• There are more species on islands that are larger and closer to the mainland.

• There are more species on islands that are larger and farther from the mainland.
