The map above shows the Channel Islands off the California coast. True or False: According to the island biogeography model, Santa Cruz would have more species than San Miguel.

True
Clarify Question
• What is the key concept addressed by the question?
o This question addresses the island biogeography model.
• What type of thinking is required?
o This question is asking you to take what you already know and apply it to this unfamiliar situation.
Gather Content
• What do you already know about the island biogeography model?
o In some newly formed habitats such as volcanic islands, succession may be affected by the ability of species to colonize isolated areas.
o Species richness is affected by the distance of the habitat from a source pool of colonists, the pool of potential species available to colonize the island, and the size of the area to be colonized.
o The equilibrium model of island biogeography holds that the number of species on an island tends toward an equilibrium number that is determined by the balance between immigration rates and extinction rates.
o In studies of the numbers of lowland forest bird species in Polynesia, the number of species decreased with the distance from the source pool of New Guinea. More distant islands contained lower numbers of species than nearer islands.
Choose Answer
• Given what you now know, what information and/or problem-solving approach is most likely to produce the correct answer?
o Santa Cruz Island, is larger than San Miguel Island. It is also closer to the continent. For these two reasons, yes, it would be expected to have a higher equilibrium number of species-a higher species diversity.
Reflect on Process
• Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
o The question required you to take what you already know and apply it to this unfamiliar situation.
o Did you recognize that large islands close to the mainland are expected to have the highest number of species?
