Chptr 35 Part 2 CONSERVATION BIOLOGY

About one-third of all animal and plant species are concentrated on of Earth's land.

• 20%.

• 10%.

• 5%.

• 1.5%.

What is likely to be the greatest challenge facing the zoned reserve systems of Costa Rica?

• High predation by jaguars.

• The impossibility of ecotourism.

• Decreasing soil erosion.

• A growing human population.

One result of Costa Rica's commitment to conservation is that _.

• Destructive practices such as massive logging and large-scale single-crop agriculture have been nearly eliminated.

• Both protected park areas and the buffer zones around them have suffered only negligible deforestation.

• Ecotourism generates many jobs and brings in a significant fraction of the country's revenue.

• About 95% of the country's land is protected in some way.

The introduction of wolves into Yellowstone National Park in 1991 resulted in _.

• A decline in habitat for the entire community.

• Ecological changes involving numerous plant and animal species.

• The migration of most of these wolves out of the park and back to Canada.

• The death of all of the wolves, likely due to an insufficient amount of available prey.

The Yellowstone to Yukon Conservation Initiative is a plan to _.

• Connect all of the national parks in the western United States.

• Connect all of the national parks in the United States.

• Connect parks in the United States and Canada with protected corridors where wildlife can travel safely.

• Create a giant, fenced private land area between the national parks in the United States to create a protected zone for wildlife.

If wolves were now removed from Yellowstone National Park _.

• Elk populations would increase.

• Deer populations would decrease.

• The vegetation would remain unchanged.

• Vegetation would increase, providing shelter for smaller animals.

The aspect of conservation ecology concerned with returning degraded ecosystems (as nearly as possible) to their natural state is _.

• Bioremediation.

• Sustainable development.

• Restoration ecology.

• Landscape ecology.

Using living organisms to clean up polluted ecosystems is known as _.

• Migration.

• Restoration ecology.

• Bioremediation.

• Landscaping.

The Kissimmee River Restoration Project is an _.

• Example of large-scale bioremediation to clean up a mercury spill.

• Example of a dam that interrupted the breeding of salmon and other species.

• Attempt to restore the natural wetlands associated with the Kissimmee River.

• Effort to join two previously unconnected lakes to permit better drainage.

The Kissimmee River Restoration Project is intended to _____.

• Drain natural wetlands in the central Florida region.

• Increase biodiversity of the region.

• Restrict ecotourism and other recreational usage in the impacted region.

• Provide areas for homes and businesses.
