How can the future number of deer, agricultural pests, or cod be calculated based on the present number of individuals and their age distribution? How long will it take for a viral outbreak in a particular city to reach another city five hundred miles away? In addressing such basic questions, ecologists today are as likely to turn to complicated ...
Aimed at readers who seek the scientific background behind contemporary issues related to the use and misuse of biology in society, this volume covers racism, genetics and evolution, gender and sexuality, the environment, the development of language and abstract thought.
The practice of growing two or more crops together is widespread throughout the tropics and is becoming increasingly practised in temperate agriculture. The benefits of nutrient exchange, reduced weed competition and pathogen control can generate substantial improvements in growth and yield. In this book John Vandermeer, a leading worker on the ...
The vanishing of the rain forest haunts our imagination, and we urgently need to understand the root causes of a global environmental crisis. In this hardhitting, scrupulously researched book, ecologists Vandermeer and Perfecto look beyond the simplistic, blame-the-victim explanations to show exactly why biodiversity is in such jeopardy around the ...
Tropical areas present ecological, cultural and political problems that demand analysis that is distinct from general ecological analysis. The tropical environment is special in many ways, from the lack of a biological down season (winter), to generally poor soil conditions, to a reliance on traditional methods of agriculture in an undeveloped ...
In Agroecology, experts from diverse disciplines define the basic concepts, research methodologies, sociopolitical aspects, and future directions of this rapidly developing field. This unique multidisciplinary review shows how researchers can learn to: develop cost-effective, environmentally sound agricultural practices; prevent the further ...
Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and ...
