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.

The Mandarin Duck is a small and (in the case of the males) spectacularly colourful species of waterfowl. Widely kept in aviaries around the world, populations often escaped to form wild colonies. One of the largest and best-studied is in southern England. Although declining and nowadays surprisingly hard to find, Britain's wild Mandarin population is probably more numerous than that of the duck's true home, China and the Russian Far East, where it is now endangered. This Poyser monograph is a detailed account of this beautiful duck's lifestyle and biology, with particular emphasis on invasive populations in Britain and overseas. It is a superb addition to the long-running and acclaimed Poyser series.

“As practical as it is poetic. . . . an optimistic call to action.” —Chicago Tribune Over time, with industrialization and urban sprawl, we have driven nature out of our neighborhoods and cities. But we can invite it back by designing landscapes that look and function more like they do in the wild: robust, diverse, and visually harmonious. Planting in a Post-Wild World by Thomas Rainer and Claudia West is an inspiring call to action dedicated to the idea of a new nature—a hybrid of both the wild and the cultivated—that can flourish in our cities and suburbs. This is both a post-wild manifesto and practical guide that describes how to incorporate and layer plants into plant communities to create an environment that is reflective of natural systems and thrives within our built world.

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

Naturalized Reptiles And Amphibians Of The World

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.

In most animals, from bees to bison, house flies to humans, it is possible to see at a glance whether an individual is male or female. How and why have these differences in appearance and behaviour developed and what are the nature and extent of the differences between men and women? This book reviews the latest molecular, genetic, hormonal, anatomical and behavioural data in a wide range of species in a series of lively and highly readable articles from the world's leading experts in this field. Such an overview has never before been attempted. It will have a wide appeal, especially to undergraduates and graduates in the biological and medical sciences, and will help to bridge the gap between those who study genes and molecules in the laboratory and those who study the behaviour of animals in the wild.

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.

A comprehensive guide that includes a vast range of species and plant communities and employs thorough, original keys. Based primarily on vegetative characteristics, the keys don't require that flowers or other reproductive features be present, like many plant guides. And this guide's attention to woody plants as a whole allows one to identify a much greater variety of plants. That especially suits an arid region such as Utah with less diverse native trees. Woody plants are those that have stems that persist above ground even through seasons that don't favor growth, due to low precipitation or temperatures. Woody Plants of Utah employs dichotomous identification keys that are comparable to a game of twenty questions. They work through a process of elimination by choosing sequential alternatives. Detailed, illustrated plant descriptions complement the keys and provide additional botanical and environmental information in relation to a useful introductory categorization of Utah plant communities. Supplementary tools include photos, distribution maps, and an illustrated glossary.
