Exam 9: Sustaining Biodiversity: Saving Ecosystems

A ____________________ contains only one species, as in a tree plantation.

One way that an individual living in a desert area could protect terrestrial biodiversity would be to xeriscape with native plants that do not require much water in the way that a traditional lawn does.

When ____________________ from the atmosphere is absorbed by ocean water, it combines with water to form carbonic acid.

The Wilderness Act passed in 1964 allows the government to ____.

Wolves were successfully reintroduced into Yellowstone National Park after being absent for almost 50 years. The reason that wolves were chosen for this effort was partly that they are a(n) ____.

Reintroduction of the wolf eventually reduced attacks on domestic cattle by what other species?

The process of logging that removes all of the trees from an area is called ____.

The Everglades in southern Florida were affected substantially by surrounding development and use of land for agricultural purposes. Additionally, introduced species have been a major problem. In one part of Everglades National Park, abandoned farmland was colonized by invasive plant species that outcompeted native species. Researchers are attempting to replace the invasive species with native species to produce an ecosystem more similar to the one that existed before these problems occurred. Which term best describes this type of study?

Once an area of tropical forest is logged and burned, ranchers can graze cattle there for decades.

Focusing on establishing and maintaining new habitats to conserve species diversity in places where people live, work, or play in order to increase our beneficial environmental impact - by learning how to share some of the spaces we dominate with other species - is called____.

When surface fires occur, they release valuable plant nutrients that had been tied up in slowly decomposing litter and undergrowth.

When managed properly, ecotourism can be a useful form of reconciliation ecology, but without proper controls, it can lead to degradation of popular sites if visitors overrun them.

What are some advantages and disadvantages to using habitat corridors?

After the number of wolves declined in Yellowstone National Park, ____.

In debt-for-nature swaps, participating countries ____.

One way to help sustain terrestrial biodiversity would be to map the world's terrestrial ecosystems and create an inventory of the species contained in each of them, along with the ecosystem services they provide.

When trees in an area have been removed by human activities, such as clear-cutting, or natural forces, such as fires and hurricanes, which type of forest develops naturally if there is no further human interference?

Despite significant efforts to protect biodiversity, Costa Rica has continued to experience biodiversity losses.
