Island 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.

The study of rates of colonization and extinction of species on islands or other isolated areas is known as

• The study of Islandology

• Genetic drift

• Demographic bottleneck

• Island biogeography

According to the Theory of Island Biogeography, which of the following statements are true?

• Larger islands are able to support more species.

• Smaller islands have more niches than larger islands.

• Islands closer to the mainland have higher species richness.

• Islands that experience a disturbance will quickly repopulate.

The theory of island biogeography suggests that species richness is affected by which of the following factors?

• II only

• III only

• I and III

• II and III

The theory of island biogeography suggests that species richness is affected by which of the following factors?

• Island distance from mainland

• How the island is formed

• Island size

• All of these are correct

Which of the following is true about island biodiversity?

• Small islands are more likely to have more immigrated species

• Small islands have higher biodiversity than large islands

• Small islands have more resources and as a result may have more species

• Small islands have fewer resources and as a result may have fewer species
