Sometimes by accident and sometimes on purpose, humans have transported plants and animals to new habitats around the world. Arriving in ever-increasing numbers to American soil, recent invaders have competed with, preyed on, hybridized with, and carried diseases to native species, transforming our ecosystems and creating anxiety among environmentalists and the general public. But is American anxiety over this crisis of ecological identity a recent phenomenon? Charting shifting attitudes to alien species since the 1850s, Peter Coates brings to light the rich cultural and historical aspects of this story by situating the history of immigrant flora and fauna within the wider context of human immigration. Through an illuminating series of particular invasions, including the English sparrow and the eucalyptus tree, what he finds is that we have always perceived plants and animals in relation to ourselves and the polities to which we belong. Setting the saga of human relations with the environment in the broad context of scientific, social, and cultural history, this thought-provoking book demonstrates how profoundly notions of nationality and debates over race and immigration have shaped American understandings of the natural world.
Larry Mayer is on a diving trip in Florida with his friend Cynthia Morrow when he runs into his friend, Joe Cole. They go with Joe to his house on St. Thomas. While there, Larry and Joe run into Luis Valero, a former CIA agent. Luis tells Larry that Joe has been a mole for the government for much longer than Joe had admitted. A couple weeks after he gets back to Ohio, Larry receives a call from Jackie Dunlap. This call leads to him and Jackie flying to Alexander Bay together. Larry receives several invitations from Melissa Macklin and eventually agrees to lead the divers on the salvage vessel after a diver dies. Larry feels uneasy about the operation, but he finds the wreck and recovers some valuable items. Just when it looks like the diving operation will start to pan out, Larry is sent ashore and fired by the owners. A day later, the federal government stops all salvage work and the diving vessels is docked and the divers and crew sent ashore. Larry returns to Ohio puzzled and tired from the ordeal.
There can only be one dominant life form on Earth. In the remote African wilderness, a rainforest is dying. But something else has come to life: A newly evolved predator that has survived the depredations of mankind, only to emerge from its natural habitat faster, stronger, and deadlier than anything humanity has ever faced. And it is no longer man.
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. In Invasive Species: What Everyone Needs to Know®, Simberloff will first cover basic topics such as how non-native species are introduced, which areas have incurred the most biological invasions, and how the rates of biological invasions have shifted in recent years. He then moves on to the direct and indirect impacts of the impacts of invasive species on various ecosystems, such as habitat and resource competition, how invasive species transmit pathogens, and how introduced plants and animals can modify a habitat to favor other non-native species. Simberloff's final chapters will discuss the evolution of invasive species, the policies we currently have in place to manage them, and future prospects for controlling their spread. The book will also contain a section dedicated to the more controversial topics surrounding invasive species: invasive natives, useful non-native species, animal rights versus species rights, and non-native species' impacts on the biodiversity of an ecosystem.

La biodiversité calédonienne, reconnue comme l’une des plus exceptionnelles avec son fort taux d’endémisme, est largement menacée par l’introduction de nouvelles espèces. Il est donc important de protéger l’écosystème calédonien, à la fois riche et vulnérable, des espèces envahissantes, l’une des principales causes de perte de la biodiversité à l’échelle mondiale. Face à cette menace, le Gouvernement et les trois provinces de Nouvelle-Calédonie souhaitent mettre en place une structure collective afin de définir les orientations stratégiques nécessaires pour préserver et conserver leur biodiversité. Elles ont ainsi voulu qu’un état des connaissances soit dressé et qu’une réflexion soit menée sur la prévention, la détection précoce, l’intervention rapide, l’éradication, le confinement et le contrôle des espèces envahissantes. Cette expertise collégiale apporte les éléments nécessaires à la construction d’un système de biosécurité pertinent et efficace pour l’archipel néo-calédonien.
