Book Description
An examination of the ecological damage that has been done by several invasive species in the Great Lakes. There are more than 180 exotic species in the Great Lakes. Some, such as green algae, the Asian tapeworm, and the suckermouth minnow, have had little or no impact so far. But a handful of others—sea lamprey, alewife, round goby, quagga mussel, zebra mussel, Eurasian watermilfoil, spiny water flea, and rusty crayfish—have conducted an all-out assault on the Great Lakes and are winning the battle. In Lake Invaders: Invasive Species and the Battle for the Future of the Great Lakes, William Rapai focuses on the impact of these invasives. Chapters delve into the ecological and economic damage that has occurred and is still occurring and explore educational efforts and policies designed to prevent new introductions into the Great Lakes. Rapai begins with a brief biological and geological history of the Great Lakes. He then examines the history of the Great Lakes from a human dimension, with the construction of the Erie Canal and Welland Canal, opening the doors to an ecosystem that had previously been isolated. The seven chapters that follow each feature a different invasive species, with information about its arrival and impact, including a larger story of ballast water, control efforts, and a forward–thinking shift to prevention. Rapai includes the perspectives of the many scientists, activists, politicians, commercial fishermen, educators, and boaters he interviewed in the course of his research. The final chapter focuses on the stories of the largely unnoticed and unrecognized advocates who have committed themselves to slowing, stopping, and reversing the invasion and keeping the lakes resilient enough to absorb the inevitable attacks to come. Rapai makes a strong case for what is at stake with the growing number of invasive species in the lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action. Although this volume tackles complex ecological, economical, and political issues, it does so in a balanced, lively, and very accessible way. Those interested in the history and future of the Great Lakes region, invasive species, environmental policy making, and ecology will enjoy this informative and thought-provoking volume.

Book Description
Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.

Book Description
A thoughtful, accessible look at the rapidly growing issue of invasive plants, animals, and microbes around the globe with a focus on the scientific issues and ecological, health, and other challenges From an award-winning adventure and science journalist comes an eye-opening exploration of a burgeoning environmental phenomenon and the science coalescing around it. Leslie Anthony leads readers on adventures physical and philosophical as he explores how and why invasive species are hijacking ecosystems around the globe. Weaving science, travel, history, and humor with diverse examples to chart and describe the phases of species invasion and human response, Anthony introduces field researchers and managers who seek to understand the biological, social, and economic aspects of this complex issue, and whose work collectively suggests the emergence of a global shadow economy centered on invasives. With tales of pythons in the Everglades, Asian carp and lamprey in the Great Lakes, Japanese knotweed seemingly everywhere, and the invasive organisms we don’t see—pathogens and microbes such as the Zika virus—this book rivets attention on a new ecological reality.

Book Description
Essay from the year 2006 in the subject Biology - Ecology, grade: A, University of Bremen (Center of Marine Tropical Ecology), course: Essay for M.Sc. course, language: English, abstract: In the first part, this essay aims at providing a rough overview about the most important topics in the literature dealing with alien invasive species. This overview tries to answer questions about the general biology of alien invasive species and the existence of a perfect invader. However, some ecosystems seem to be more susceptible to invasion than others do. General assumptions are that the tropics are less invasible than temperate regions and that islands are more vulnerable than continental areas. An alien species must complete three stages of human-mediated spreading which are transportation, introduction and establishment in order to become invasive. An alien invasive species might then have positive or negative impacts. Either it adds to the species richness or it has detrimental effects on the ecological, economical or human health sector. However, sophisticated treatments are available to prevent several means of introduction. The second part of this essay will provide a critical evaluation about the literature reviewed. There still exists a great deal of uncertainty and variety of opinions within publications. The need of increased prevention of introductions and collaboration are conclusions that can be drawn. Furthermore, public awareness has to be raised and a clear definition of terms is a must. Finally, it is important to recall that many alien species are responsible for human well-being by providing food and aesthetics.
