with Sean Carroll, PhD, Beth McGee, PhD, Mary E. Power, PhD, and Brian R. Silliman, PhD

  1.  1.  Introduction and the role of science and policy
  2.  2.  Low oxygen concentrations are a key stress in Chesapeake Bay
  3.  3.  Water clarity controls the amount of underwater grasses
  4.  4.  Nitrogen, phosphorus, and sediment are three main types of pollution
  5.  5.  Overharvesting of menhaden in the Bay has altered the food web
  6.  6.  Q&A: Are programs that use fences to protect streams cost-effective?
  7.  7.  Q&A: How do invasive species affect the Bay food web?
  8.  8.  Q&A: How did the Chesapeake Bay form?
  9.  9.  Q&A: How do species invasions get started?
  10. 10.  Q&A: How can we reduce the deer population in the Bay watershed?
  11. 11.  Q&A: How can we reduce runoff in heavily developed areas?
  12. 12.  Q&A: How does pumping ground water affect ecosystems?
  13. 13.  Q&A: How do you remove invasive species from an ecosystem?
  14. 14.  Q&A: How do plastic microbeads affect ecosystems?
  15. 15.  Q&A: Would fish rather starve than go into a dangerous area?
  16. 16.  Q&A: Have you seen evidence of ocean acidification in your research?
  17. 17.  Q&A: What factors besides climate may cause grazer fronts?
  18. 18.  Q&A: Would mycorrhizal fungi make plants more resistant to stress?
  19. 19.  Q&A: Why are grazers more resistant to environmental stress than predators?
  20. 20.  Q&A: Is it more cost-effective to prevent or repair environmental damage?
  21. 21.  Q&A: How is the striped bass population recovery progressing?
