Charles Elton was one of the founders of ecology, and his Animal Ecology was one of the seminal works that defined the field. In this book Elton introduced and drew together many principles still central to ecology today, including succession, niche, food webs, and the links between communities and ecosystems, each of which he illustrated with well-chosen examples. Many of Elton's ideas have proven remarkably prescient—for instance, his emphasis on the role climatic changes play in population fluctuations anticipated recent research in this area stimulated by concerns about global warming.

For Chicago's reprint of this classic work, ecologists Mathew A. Leibold and J. Timothy Wootton have provided new introductions to each chapter, placing Elton's ideas in historical and scientific context. They trace modern developments in each of the key themes Elton introduced, and provide references to the most current literature. The result will be an important work for ecologists interested in the roots of their discipline, for educated readers looking for a good overview of the field, and for historians of science.

Much as Rachel Carson's Silent Spring was a call to action against the pesticides that were devastating bird populations, Charles S. Elton's classic The Ecology of Invasions by Animals and Plants sounded an early warning about an environmental catastrophe that has become all too familiar today—the invasion of nonnative species. From kudzu to zebra mussels to Asian long-horned beetles, nonnative species are colonizing new habitats around the world at an alarming rate thanks to accidental and intentional human intervention. One of the leading causes of extinctions of native animals and plants, invasive species also wreak severe economic havoc, causing $79 billion worth of damage in the United States alone.

Elton explains the devastating effects that invasive species can have on local ecosystems in clear, concise language and with numerous examples. The first book on invasion biology, and still the most cited, Elton's masterpiece provides an accessible, engaging introduction to one of the most important environmental crises of our time.

Charles S. Elton was one of the founders of ecology, who also established and led Oxford University's Bureau of Animal Population. His work has influenced generations of ecologists and zoologists, and his publications remain central to the literature in modern biology.

"History has caught up with Charles Elton's foresight, and The Ecology of Invasions can now be seen as one of the central scientific books of our century."—David Quammen, from the Foreword to Killer Algae: The True Tale of a Biological Invasion

From its creation by Charles Elton in 1932 to its demise when he retired in 1967, the Bureau of Animal Population at Oxford was a mecca for ecologists from around the world. Crowcroft provides an anecdotal history of this small research institute that so strongly influenced the development of modern animal ecology.

"[This] is a very good account of the work and personal interactions of a group that played an important part in the development of animal ecology in the period 1930-60."—John Krebs, TREE
