[...]... therefore ecosystem engineers? If so, isn’t the concept too broad to be useful? Don’t engineers always have large or large-scale impacts? Shouldn’t engineers be limited to species with large effects? Aren’t engineers and keystone species the same? Isn’t engineering equivalent to facilitation or positive influence? Isn’t the approach overly reductionist? Why do we need the concept? How can we use it? Ecosystem. .. examples of ecosystem engineers A major aim of this section is to provide tangible, highly varied examples to apply to conceptual and theoretical developments in other sections Chapters in Section 3 develop the mathematical theory of ecosystem engineers and review the very brief ecosystem engineer theoretical literature Finally, the authors of Section 4 address applied Preface examples where ecosystem engineers. .. important to the success or failure of resource management, restoration, or conservation Each section has a concluding chapter that brings together the contributions in that section into a more unified framework We hope that the biggest contributions of our book are to stimulate discussion of ecosystem engineering, and perhaps spur further development of viable tools to aid its study, particularly to practical...
