Theory of Island Biogeography

What is is the study of how and why plants and animals live where they do?

• Evolution

• Adaptive Radiation

• Biogeography

• Biogeology

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

I. island distance from mainland

II. how the island is formed

III. island size

• II only

• III only

• I and III

• II and III

Which is NOT a factor in the theory of island biogeography?

• Islands farther from the continent have more species due to increased speciation
• dispersing species are more likely to find a large habitat
• islands can also be isolated areas within a continent
• larger habitats contain a larger range of environmental conditions

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

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 LESS genetically diverse a population is, the better it can respond to environmental stressors

• True

• False
