Instructions

Check your understanding of concepts from 16·12–16·14 We can develop strategies for effective conservation by answering the following questions.

1.

1. Increased exposure to short-wavelength ultraviolet radiation by depletion of stratospheric ozone:

increase the acidification of lakes and streams.

has raised the average daily temperature on the earth’s surface by 4% per decade.

reduces the rate of photosynthesis by plants.

has lowered the average daily temperature on the earth’s surface by 4% per decade.

increases the rate of photosynthesis by plants.

Correct. (See section 16·12 Reversing ozone layer depletion illustrates the power of good science, effective policymaking, and international cooperation.)

Incorrect. (See section 16·12 Reversing ozone layer depletion illustrates the power of good science, effective policymaking, and international cooperation.)

2.

2. Ozone holes tend to form in the stratosphere over:

the oceans.

areas of high industrial activity.

the continents.

areas with high greenhouse gas concentrations.

the poles.

Correct. (See section 16·12 Reversing ozone layer depletion illustrates the power of good science, effective policymaking, and international cooperation.)

Incorrect. (See section 16·12 Reversing ozone layer depletion illustrates the power of good science, effective policymaking, and international cooperation.)

3.

3. A flagship species is one that:

conservationists use to protect all of the other species that associate with it.

conservationists use to increase public knowledge and support for all conservation issues.

humans have transported, usually through the shipping industry, from its natural habitat to an exotic location.

if removed from an ecosystem, will cause that ecosystem to collapse.

indicates the presence of a suite of species that associate with it in a particular ecosystem type.

Correct. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)

Incorrect. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)

4.

4. An umbrella species:

is a species whose removal will severely damage or cause the collapse of its ecosystem.

is a term used for any species with a larger than expected effect on its ecosystem.

is a non-native species, usually introduced to an area on accident.

is a popular species that the public tends to rally behind and support.

is a species whose protection results in the protection of many other species as well.

Correct. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)

Incorrect. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)

5.

5. When preserving areas to act as reservoirs for biodiversity, corridors are important because:

they increase the interactions at the edges of ecosystems, thus increasing species diversity.

they decrease the rates of local extinctions.

they increase the rates of local extinctions.

they increase rates of gene flow between the areas they connect.

they increase the interactions at the edges of ecosystems, thus decreasing species diversity.

Correct. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)

Incorrect. (See section 16·14 There are multiple effective strategies for preserving biodiversity.)
