• The genetic diversity of livestock has declined during the past century.

• Different breeds are adapted to different climatic conditions.

• Different breeds are adapted to resist different diseases.

Which statement is NOT correct about invasive exotic species?

• Their populations grow rapidly.

• They often have no major predators or herbivores.

• The Biosphere Reserve

Which is NOT an example of how the Endangered Species Act can affect human activities?

• It has been used to prevent new construction.

• It has prevented logging in particular areas.

• I prevents the killing of listed species.

• It prevents the trade of any parts of listed species.

• It prevents human use of biosphere reserves.

Which principle of island biogeography is NOT correct?

• A larger protected area should contain more species.

• Protected areas that are closer together should contain more species.

• National parks can be thought of as islands of biodiversity.

• A larger protected area will have fewer habitats.

• Marine reserves can be thought of as islands of biodiversity.

In a biosphere reserve

• sustainable agriculture and tourism are permitted in different zones.

• human activities are allowed throughout the reserve.

• human activities are restricted to the central core of the reserve.

• no human activities are permitted in a biosphere reserve.

• sustainable agriculture is permitted but tourism is not.
