Elton sought to articulate more explicitly his vision of an entire field of invasion science. The 1958 book, aimed at an educated lay audience, was almost wholly descriptive, dominated by striking examples of the nature and scope of particular invasions beginning with the seven examples detailed in Chapter 1. From the materials in the proof copy and other sources, we can imagine a new edition would also have targeted biologists and been somewhat more technical and prescriptive. In autobiographical notes he penned near the end of his life, Elton wrote regarding EIAP, "This whole subject has deep significance for the study of plant and animal communities and their balance (or unbalance),"19 and indeed many of the reprints and notes refer to interactions among species and community-wide effects.
Of the 7,000 estimated non-native species present in North America,
approximately 1,000 are invasive. Clearly, invasive species are in
the minority, but their small numbers don't keep them from causing
billions of dollars in economic and ecological harm each year.
Policymakers and ecologists continue to try to figure out which
species might be harmful, which invasive species are doing the most
damage, and which of these might respond best to eradication
efforts. Invasive species reports and case studies are prevalent in
political, environmental, and scientific news cycles, and a
significant portion of the public is concerned about the issue.
This work is the first to focus systematically on a much-debated topic: the conceptual issues of community ecology, including the nature of evidence in ecology, the role of experiments, attempts to disprove hypotheses, and the value of negative evidence in the discipline. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Invasive species come in all sizes, from plant pathogens like the chestnut blight in eastern North America, to the red imported fire ant that has spread throughout the South, the predatory Indian mongoose now found in the Caribbean and Hawaii, and the huge Burmese python populating the Florida swamps. And while many invasive species are safe and even beneficial, the more harmful varieties cost the world economy billions of dollars annually, devastate agriculture, spread painful and even lethal diseases, and otherwise diminish our quality of life in myriad surprising ways. In Invasive Species: What Everyone Needs to Know, award-winning biologist Daniel Simberloff offers a wide-ranging and informative survey that sheds light on virtually every aspect of these biological invaders. Filled with case studies of an astonishing array of invasive species, the book covers such topics as how humans introduce these species-sometimes inadvertently, but often deliberately-the areas that have suffered the most biological invasions, the methods we use to keep our borders safe, the policies we currently have in place to manage these species, and future prospects for controlling their spread. An eminent ecologist, Simberloff analyzes the direct and indirect impacts of invasive species on various ecosystems, such as when non-native species out-compete native species for food or light, describes how invasive species (such as the Asian mosquito that is a vector for West Nile virus, itself an invasive species) transmit pathogens, and explains his acclaimed theory of "invasional meltdown" in which two or more introduced species combine to produce a far more devastating impact than any one of them would have caused alone. The book also discusses the more controversial issues surrounding invasive species and it concludes with suggested readings and a list of related web sites.

In the late 1970s, a Stuttgart zoo imported a lush, bright green seaweed for its aquarium. "Caulerpa taxifolia" was captively bred by the zoo and exposed, for years, to chemicals and ultraviolet light. Eventually a sample of it found its way to the Oceanographic Museum in Monaco, then headed by Jacques Cousteau. Five years later, while cleaning its tanks, that museum dumped the pretty green plant into the Mediterranean. This supposedly benign little plant - that no one thought could survive the waters of the Mediterranean - now covers 10,000 acres of the coasts of France, Spain, Italy and Croatia, and has devastated the Mediterranean ecosystem. And it continues to grow, unstoppable and toxic. When Alexandre Meinesz discovered a square-yard patch of it in 1984, he warned biologists and oceanographers of the potential species invasion. His calls went unheeded. At that point, one person could have weeded the small patch out and ended the problem. Now, however, the plant has defeated the French Navy, thwarted scientific efforts to halt its rampage, and continues its destructive journey into the Adriatic Sea. This text presents the biological and political horror story of this invasion. For despite Meinesz's pleas to scientists and the French government, no agency was willing to take responsibility for the seaweed, and while the buck was passed, the killer algae grew. In short, this work - part detective story and part bureaucratic object lesson - is a classic case of a devastating ecological invasion and how "not" to deal with it.

seaweed for its aquarium. "Caulerpa taxifolia" was captively bred
by the zoo and exposed, for years, to chemicals and ultraviolet
light. Eventually a sample of it found its way to the Oceanographic
Museum in Monaco, then headed by Jacques Cousteau. Fifteen years
