During the inventory of bacterial genes present in the Sargasso Sea in the middle of the Atlantic Ocean, a research team concluded that at least 1800 bacterial species were discovered. Based on what you know about this area, what would you expect to see in coral reef waters?

In a debate about the destruction of tropical wet forests, the arguments keep focussing on biodiversity and how this affects the animals themselves, as well as the ecosystem. What is one direct benefit of biodiversity to humans that you can argue to help people understand why these forests need to be preserved?

Which of the following statements regarding species diversity is FALSE?

Figure 54.2 -Based on Figure 54.2, what snake antivenom would you administer to a person bitten by a king brown snake?

How can biodiversity affect the way we decontaminate industrial sites?

Figure 54.7 -Based on the species- area plot in the figure above, if habitable area on an island were reduced from 10,000 km² to 1,000 km², roughly what percentage of the species would disappear?

Figure 54.9 -Based on Figure 54.9, what can you conclude about land- use legacy in New England?

Figure 54.6 -In looking at the figure above, what can be said about edge effects?

Researchers have been studying a rare population of 87 voles in an isolated area. Ten voles from a larger population were added to this isolated population. Besides having 10 additional animals, what benefits are there to importing individuals?

What is the main purpose of the wildlife corridor?

The main focus in combating loss of biodiversity is

According to the figure above, what is the least likely explanation for the data after 1985?

If the last remaining population of a particular bird species were all highly related, which type of diversity would be of greatest concern when planning to keep the species from going extinct?

Figure 54.7 -In looking at the species- area plot in the figure above, what can be concluded?

Which one of the following is likely not a hotspot for birds?

Use the following information when answering the corresponding questions). Abstract: Recognition of the importance of land- use legacies in most ecological systems has been a major factor driving the recent focus on human activity as a legitimate and essential subject of environmental science. Ecologists, conservationists, and natural resource policy makers now recognize that the legacies of land- use activities continue to influence ecosystem structure and function for decades or centuries-or even longer-after those activities have ceased. Figure 54.8 -Based on the figure above, what can you conclude about land- use legacy in the southern Yucatán?

Ecosystems services include processes that increase the quality of the abiotic environment. Which of the following processes would not fall under this category?

Figure 54.4 -Hypothesis: Productivity increases with species richness because certain species or functional groups facilitate the growth of other species by providing them with nutrients, partial shade, or other benefits. In looking at the data in Figure 54.4, how would you relate it to this hypothesis?

You discover, in your massive 2000- hectare forest, a species of bat that is not found anywhere else. The habitat of your bat population is designated as a protected area. What, if any, would be an advantage of removing a small number of bats and placing them in a zoo?
