The vector-borne Zika virus joins avian influenza, Ebola, and yellow fever as recent public health crises threatening pandemicity. By a combination of stochastic modeling and economic geography, this book proposes two key causes together explain the explosive spread of the worst of the vector-borne outbreaks. Ecosystems in which such pathogens are largely controlled by environmental stochasticity are being drastically streamlined by both agribusiness-led deforestation and deficits in public health and environmental sanitation. Consequently, a subset of infections that once burned out relatively quickly in local forests are now propagating across susceptible human populations whose vulnerabil...
Heather Wright is always all right. That's what people say. But if she's always all right, then why is life so hard?

This book describes the theoretical basis and practical application of 20 diverse silvicultural systems for the benefit of ecologists, land-use managers and other professionals. These systems offer the key to regenerating, tending, and harvesting forests in an era of rapid deforestation and increasing demand for wood as fuel and building material. The approaches described here are being used successfully in widely different parts of the world, from Europe to the tropical rain forests, where reduced forest areas must be carefully managed in order to produce the highest possible sustained yield of timber products compatible with environmental protection and preservation. The systematic presentation and discussion of advantages and disadvantages of each program enables readers to select and apply the program most suitable for their needs.
