Tigers living in warm climates have thinner coast 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:

• organization 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

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 meridan

• decreases in warmer climates

• increases toward the poles
