Exam 56: Conservation Biology and Global Change

Which one of the following is most likely to be a hot spot of biodiversity for birds?

Agricultural lands frequently require nutrient augmentation because ________.

Elevated carbon dioxide levels have been shown to contribute to the greenhouse effect, resulting in an increase in mean global temperature. Ecosystems where the largest warming has already occurred include snow-covered northern coniferous forests, tundra, and arctic sea ice habitats. Which statement best explains how the elimination of ice-covered ecosystems affects the rise or fall in global temperature?

Eutrophication is often caused by excess limiting-nutrient runoff from agricultural fields into aquatic ecosystems. This process results in massive algal blooms that eventually die and decompose, ultimately depleting the dissolved oxygen, killing large numbers of fish and other aquatic organisms. Predict which of the following human actions would best address the problem of eutrophication near agricultural areas?

Which of the following terms includes all of the others?

Which of the following statements about protected areas that have been established to preserve biodiversity is correct?

Which of the following criteria have to be met for a species to qualify as invasive?

Tropical forests are being converted to farm or pasture land at an alarming rate, and one major focus is on the biodiversity and the impact to these ecosystems. What is a direct benefit to humans that helps explain why these forests need to be preserved?

During the inventory of bacterial genes present in the Sargasso Sea, a deep isolated area in the middle of the Atlantic Ocean, a research team concluded that at least 1,800 bacterial species were present. Based on what you might predict about the habitat structure of such an area, what kind of bacterial diversity would you expect to see in tropical coral reef waters?

Which of the following nations has become a world leader in the establishment of zoned reserves?

Which of the following is a consequence of biological magnification?

Establishing new nature reserves in biodiversity hot spots may not necessarily the best choice because ________.

Use the following figure to answer the question. Looking at the figure, what can you conclude about the data?

Which of the following is a generally accurate statement about the current research regarding forest fragmentation?

Movement corridors can be harmful to certain species because they ________.

Which of the following statements is accurate with respect to the red-cockaded woodpecker populations in the southeastern United States?

Burning fossil fuels releases oxides of sulfur and nitrogen. These air pollutants can be responsible for ________.

The primary difference between the small-population approach and the declining-population approach to biodiversity recovery is that ________.

The main goal of sustainable development is to ________.

Use the following figure to answer the question. Examine the figure and consider this hypothesis: Plant biomass increases with species richness. Functional groups are categories of plants each containing numerous species, such as grasses and wildflowers, or trees and shrubs. In looking at the data in the figure, how would you relate it to this hypothesis? The hypothesis is ________.
