This book looks at the world's naturalised (successfully introduced) species of bird. Many species have been introduced to countries outside their natural range by people, either deliberately or accidentally, with varied consequences for both those species themselves and the native fauna of their 'new' homes. In Britain, the introduced Canada Goose has quickly become ubiquitous at every lake and riverside, while the Golden Pheasant remains a scarce and unobtrusive inhabitant of a few scattered, remote woodlands. The House Sparrow and Common Starling, both in decline over parts of their native range, are thriving in a naturalised state in North America and elsewhere in the world. Naturalised populations of Mallard in various parts of the world are threatening a total of seven other duck species with extinction through hybridisation. This book discusses each species in turn, describing how, why, when and where its introduction took place, how it became established, and the ecological and economic impacts its presence has had in the country or countries it is naturalised in. Each account has a map, showing natural and introduced range, and there is a wealth of beautiful line drawings of the species concerned.

Fish are an important part of a region's biological diversity and a human resource throughout the world. They are valuable for food and/or as a sporting asset. The human interest in fish has inevitably led to the widespread practice of introducing various species to waters outside their normal range. This unique book describes when, where, why, how, and by whom the alien inland fishes now living in a wild state throughout the world were introduced. It also exploreshow they subsequently became naturalized and what, if any, effects they have had in their new environment. Includes a comprehensive index useful for cross-referencing Explains the multiplicity of technical terms in a complete glossary Provides country listings with naturalized fish species Explores the benefits and drawbacks of species displacement in their new ecosystems

This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact (if any) on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency (either accidentally or deliberately) and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by, and independent of, mankind.

Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

Kaninchenplage in Australien, Ameisen in Großcomputern und Krankenhäusern, Piranhas in französischen Flüssen – mit solchen Ereignissen beschäftigt sich die Invasionsbiologie. Seit jeher ist die Besiedlung neuer Lebensräume für Tiere und Pflanzen eine Überlebensfrage. Früher gab es Hindernisse, die sich der Reiselust widersetzten. Gebirge, Ozeane, Kontinente, Wüsten bildeten unüberwindbare Barrieren. Mit dem Erscheinen des modernen Menschen hat sich die Situation verändert. Ein Netz von Verkehrswegen verbindet, was über Jahrmillionen getrennt war. Bei Warentransporten von einem Kontinent zum anderen reist die Natur mit. Bernhard Kegels faszinierendes Buch erzählt, welche erstaunlichen Folgen das für uns und unsere Umwelt hat.

Obwohl Effia und Esi Schwestern sind, lernen sie sich nie kennen, denn ihre Lebenswege verlaufen von Anfang an getrennt. Im Ghana des 18. Jahrhunderts heiratet Effia einen Engländer, der im Sklavenhandel zu Reichtum und Macht gelangt. Esi dagegen wird als Sklavin nach Amerika verkauft. Während Effias Nachkommen über Jahrhunderte Opfer oder Profiteure des Sklavenhandels werden, kämpfen Esis Kinder und Kindeskinder ums Überleben: auf den Plantagen der Südstaaten, während des Amerikanischen Bürgerkrieges, der Großen Migration, in den Kohleminen Alabamas und dann, im 20. Jahrhundert, in den Jazzclubs und Drogenhäusern Harlems. Hat die vorerst letzte Generation schließlich die Chance, einen Platz in der Gesellschaft zu finden, den sie Heimat nennen kann und wo man nicht als Menschen zweiter Klasse angesehen wird? Mit einer enormen erzählerischen Kraft zeichnet Yaa Gyasi die Wege der Frauen und ihrer Nachkommen über Generationen bis in die Gegenwart hinein. ›Heimkehren‹ ist ein bewegendes Stück Literatur von beeindruckender politischer Aktualität. New-York-Times-Bestseller Das Hörbuch erscheint am 4. August bei DAV, gelesen von 14 Sprecherinnen und Sprechern: Bibiana Beglau, Wanja Mues, Britta Steffenhagen, Götz Schubert, Johann von Bülow, Stefan Kaminski, Felix Goeser, Bjarne Mädel, Max Mauff, Rike Schmid, Jodie Ahlborn, Jule Böwe, Judith Engel, Lisa Wagner

Die Polizei und ein Drogenboss setzen Starr und ihre Familie unter Druck. Was geschah an jenem Abend wirklich? Die Einzige, die das beantworten kann, ist Starr. Doch ihre Antwort würde ihr Leben in Gefahr bringen...
