Chapter 12 Study Questions

  1. Conservation organizations sometimes invoke metapopulation structure as a rationale for protecting small areas. Explain this rationale. What minimal information is needed to determine if metapopulation structure exists?
  2. There is considerable debate about the best way to manage endangered species. At the extremes, one school of thought holds that a species-based approach is essential, while the other school argues that we should use an ecosystem-based approach. In the context of this chapter and of Chapter 13, discuss the pros and cons of each approach. Are they mutually exclusive approaches to biodiversity protection?
  3. Cranes exemplify the need for conservation management across political boundaries in order to achieve conservation goals. Think of another family of organisms and consider the needs for conservation of this group. For example, what might the conservation needs of sturgeon or parrots be?
  4. Wildlife biologists have very successfully increased populations of white-tailed deer in North America. What characteristics of the contemporary landscape in eastern North America have helped increase the deer population? How can these deer populations be managed in human-dominated landscapes where hunting creates too much risk? White-tailed deer are expanding their range into tropical South America. Should they be considered invasive species there?
