1. What are the 6 threats to biodiversity and give an example of each?

2. What determines the success of an invasive species?

3. What are the distinctions between "critically endangered", "endangered", and "vulnerable" species?

4. What are good predictors of successful species invasion?

5. How does habitat fragmentation contribute to species extinction?

6. How do we estimate rates of species loss?

7. What are the protected area categories for the IUCN?

8. What is a Gap Analysis and how is it used?

9. What is necessary to have an effective nature reserve?

10. Describe the difference between background, mass, and anthropogenic extinctions.

11. Of the Sextet of Threats, which are the most important? Although it isn't considered one of the biggest threats, what is an important threat for oceans and bushmeat animals?

12. How does human intervention exacerbate species extinction?

13. How can we measure the value of biodiversity?

14. Given the varying reasons for species extinction, how can we as humans best protect biodiversity? And what are some of the possible parameters we can use to measure effectiveness?

Biodiversity Interesting questions:
1. Choose one of the six threats to biodiversity presented in lecture and argue why it is the most important. What are the implications of this threat? What natural ecosystems are impacted by it? What human institutions are impacted by the threat? What policies would you present or support to address this threat?
2. Describe how the relationship between habitat area and number of species relates to forecasting of future extinctions? Is this true in all cases? Why do different sized islands demonstrate this effect so effectively?
3. Define/ in biodiversity terms:
a. Endemism
b. Hot spots
c. Matrix
d. Domino effect
e. Size matters
f. Nuisance is in the eye of the beholder
4. Give a quick “elevator speech” of why we are in the sixth extinction and what it means for the future of humanity.
