- What is biological diversity? Compare, contrast and give examples of species richness, genetic diversity and ecosystem diversity. Why is biological diversity important?
- What are examples of ecosystem services?
- What are the characteristics that make a species more vulnerable to extinction? What are examples of human causes of species endangerment? Be able to name at least two endangered species beyond those mentioned in the book. When identifying endangered species, be sure to identify where and why they are endangered. What is the difference between background and mass extinction?
- Identify direct causes of human induced species endangerment. What is the greatest threat to biological diversity? What underlying factors or indirect causes contribute?
- Define an invasive species and biotic pollution. What kind of harm do invasive species inflict? What are examples of invasive species in California and/or Sonoma County? Why are these species considered to be invasive? Why do invasive species often do better than native species? Are all non-native species considered invasive?
- What is the difference between endemic and invasive species?
- What is Conservation biology? Protecting habitats, restoring habitats, reintroducing endangered species, seed banks. Ex situ versus in situ conservation. Examples of how this is being done.
- Endangered Species Act (ESA) – when was it passed? What does it authorize? According to the Act what is endangered and what is threatened? What successes has the ESA been able to accomplish? What are specific examples of endangered species that have been placed listed under the Endangered Species Act?
- What is an indicator or bellwether species (also called sentinel species). What are examples of indicator species?
- Other: endemic versus invasive. Habitat fragmentation, wildlife corridors, biodiversity hotspots,
Additional Topics not necessarily in the book
- What is genetic engineering (GE) and genetically modified organisms (GMO)? How is genetic engineering different than conventional breeding? Give specific examples of organisms that have been genetically modified. What are examples of existing and potential uses of GMO’s? What are the pros and cons associated with genetic engineering?
Potential Paragraph Questions
- Is biological diversity a renewable or nonrenewable resource? Why could it be seen in both ways? Make sure to define renewable and nonrenewable resources in your answer.
- What is conservation biology and what strategies are used to cope with declining biological diversity. What are examples of projects being done?
- Compare and contrast invasive and endangered species and provide specific examples of each in your answer. Define invasive and endangered in your answer.
- Define the term genetically modified organisms (GMO), identify two specific examples of GMO’s (including what specific organisms were combined and why) and give two arguments for and two arguments against their use.
