A. Differences between islands and other types of habitats

B. An approach to reducing the impact of habitat fragmentation on wildlife

C. Determining the effectiveness of wildlife corridors

D. A theory about why an increase in habitat fragments has not led to greater biodversity in those fragments

2. What does the theory of island biogeography attempt to explain?

A. Factors that affect the number of species on islands

B. Consequences of introducing new spocies onto islands

C. Why some animals migrate farther than other animals of the same species

D. Why certain animal species live in specific isolated areas

D. The island’s distance from other landmass

4.What is the relationship between habitat fragmentation and the theory of island biogeography?

A. They are opposing explanations for the reduction in species blodiversity on islands

B. Habitat fragmentation was ackknowledged as a problem only after the theory of island biogeooraphy had been developed.

C. The theory of island biogeography was applied to address problems caused by habtat fragmentation.

D. The theory of island biogeography may predict where habitat fragmentation is likely to occur.

5. Why does the professor mention wolves and elephants?

A. To describe wildlife corridors that produced unexpected results

B. To explain why some areas do not need wildlife corridors

C.To illustrate why wildlife corridors need to differ in size

D. To point out an unanticioated danger of wildlife corridors

6.What is the professors opinion about the usefulness of wildlife corridors?

A. They should be indluded in plans of all new constructian projects.

B. They probably have no effect on the number of species in fragmented habitats

C. Most animal specles could thrive in fracmented habitats without wildite corridors

D. More research is needed before determining which wildife corridors are helpful
