1)In the context of conservation biology, what does genetic diversity mean?

2. What is a biodiversity "hotspot?"
3. According to Figure 54.4, which of the following locations has the highest numbers of endemic birds?
4. What is habitat fragmentation?
5. Which of the following is NOT a reason why habitat quality deteriorates when fragmentation occurs?

6. Stochastic processes are random and/or unpredictable. Which of the following represents a stochastic process that can have a disproportionately large impact on small populations?
7. The graph in Figure 54.10 shows the relationship between the size of a habitat (in Polynesia) and the number of bird species found there. According to these data, if a habitat of 100,000 km^2 were reduced to 10,000 km^2 by logging, about how many bird species would be lost?
8. What is "genetic restoration" of endangered species?
9. What is a wildlife corridor?
10. What does it mean to say that a plant community provides ecosystem services? (please look back at p. 1154)
11. What is ecological restoration?
12.  “Diversity leads to stability.” This slogan claims that ecosystems with a large number of species present are more stable than ecosystems with a low number of species. Which of the following lines of evidence support this claim?
13. In biological communities, what is "resistance?
14. In biological communities, what is "resilience?"
15. Both sets of data graphed in Fig. 54.12 have the same general shape. Which of the following is the best interpretation of this pattern?
