Tigers living in warm climates have thinner coats of fur than tigers living in cool climates. This is a result of

• genetic diversity.
• species diversity.
• ecosystem diversity.
• general diversity.

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Convention on Biological Diversity are examples of

• organizations that promote poaching.
• polls measuring American opinion about biodiversity.
• treaties to protect biodiversity.
• laws to increase the number of species.

To manage, protect, and reintroduce threatened and endangered species are the goals of

• wildlife corridors.
• conservation concessions.
• Species Survival Plans.
• biodiversity hotspots.

Relieving a nation from repaying some of the money it owes other nations in exchange for protecting its biodiversity is called a

• debt-for-nature swap.
• conservation concession.
• Species Survival Plan.
• wildlife corridor.

A region that includes tigers, eagles, lizards, fish, rabbits, and many other types of organisms would be described as having a high level of

• taxonomic diversity.
• genetic diversity.
• ecosystem diversity.
• species diversity.

The latitudinal gradient is a natural pattern in which species diversity generally

• increases toward the equator.
• decreases toward the prime meridian.
• decreases in warmer climates.
• increases toward the poles.

High levels of biodiversity tend to

• have little or no effect on ecosystems.
• decrease an ecosystem’s resistance.
• make an ecosystem less resilient.
• increase the stability of an ecosystem.

Which product is often derived from the natural environment?

• cooking oil
• medicines
• fuel
• all of the above

The disappearance of a particular population from a given area, but not of the entire species globally, is called

• extirpation.
• extinction.
• poaching.
• fragmentation.

A species that is at serious risk of extinction is called a(n)

• threatened species.
• invasive species.
• endangered species.
• extirpated species.
