Review

Genetic diversity: source of variations that enable

populations to adapt to environmental changes

Species diversity: important in maintaining structure

of communities and food webs

Ecosystem diversity: Provide life-sustaining services

such as nutrient cycling and waste decomposition

Slide 52

You should now be able to:

Distinguish between conservation biology and restoration biology.

List the three major threats to biodiversity and give an example of each.

Define and compare the small-population approach and the declining-population approach.

Distinguish between the total population size and the effective population size.

Slide 53

Describe the conflicting demands that may accompany species conservation.

Define biodiversity hot spots and explain why they are important.

Define zoned reserves and explain why they are important.

Explain the importance of bioremediation and biological augmentation of ecosystem processes in restoration efforts.

Slide 54

Describe the concept of sustainable development.

Explain the goals of the Sustainable Biosphere Initiative.
