- 13. Multiple ChoiceWhich is NOT a factor in the theory of island biogeography?Islands farther from the continent have more species due to increased speciationdispersing species are more likely to find a large habitatislands can also be isolated areas within a continentlarger habitats contain a larger range of environmental conditions
- 14. Multiple Choice
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
- 15. Multiple Choice
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.
