This is a concise, very clear overview of the nonequilibrium dynamics in ecosystems -- why natural "disasters" are actually beneficial to the environment by encouraging biodiversity. The old, equilibrium models miss the fundamental role of the environment in species frequency and distribition -- see The Theory of Island Biogeography (E. O. Wilson) and The Song of the Dodo (David Quammen). While I thorougly enjoyed The Song of the Dodo as creative science writing, this drier and shorter volume provides a better basis for thinking about, and managing, our environment.
