• 
  
• Includes case studies and interviews with prominent conservation scientists to help situate key concepts in a real world context
  
• Covers a broad range of topics including: the fate of the coral reefs; the impact of agriculture, urbanization, and logging on habitat depletion; and the effects of fire on plants and animal survival
  
• Highlights conservation successes in the region, and emphasizes the need to integrate social issues, such as human hunger, into a tangible conservation plan
  
• Documents the current state of the field as it looks for ways to predict future outcomes and lessen human impact

Sodhi et al. have done a masterful job of compiling a great deal of literature from around the tropical realm, and they have laid out the book in a fruitful and straightforward mannerI plan to use it as a reference and as supplemental reading for several courses and I would encourage others to do the same.Ecology, 90(4), 2009, pp. 11441145
