Naturalized Reptiles and Amphibians of the World by Christopher Lever Pdf

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 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.

Naturalised Birds of the World by Christopher Lever Pdf

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.

Reptiles and Amphibians of the Pacific Islands by George R. Zug Pdf

The Pacific is not only the world’s largest body of water; its vast expanse also includes an extraordinary number and diversity of oceanic islands, from Palau and the Marianas east of the Philippines to Cocos Island and the Galápagos west of the Americas. The isolation of these islands and the extreme distances between them long prevented scientists from studying their floras and faunas in a comparative context. But now George R. Zug, one of the world's foremost experts on the diverse reptiles and amphibians of the Pacific Basin, offers the first such systematic overview in more than half a century. Reptiles and Amphibians of the Pacific Islands is a compendium of frogs, lizards, snakes, and turtles living on these lands and in the adjacent waters of the oceanic islands in the tropical Pacific. The means to identify each species is included, along with entries that describe each animal's form, coloration, habitat, distribution, reproductive biology, and natural history. Color plates of more than 75 percent of the species also help to facilitate visual identification. This accessible and informative guide is the most comprehensive field guide available and will appeal to both novice sightseers and professional naturalists.

Exotic Amphibians and Reptiles of the United States by Walter E. Meshaka Jr.,Suzanne L. Collins,R. Bruce Bury,Malcolm L. McCallum Pdf

The first complete field guide to the exotic amphibians and reptiles established in the continental United States and Hawaiʻi, this volume covers 74 species that are not native to the country and 29 species that are native but occur beyond their original geographic range. Dispersed from their former habitats by human activity, many of these species are invasive in their new environments, causing ecological or economic harm. Ideal for naturalists of all levels, Exotic Amphibians and Reptiles of the United States details each species’ taxonomy, distribution, history, and ecology and portrays each one with vibrant photographs. Drawing on county-level distribution maps from 2,908 published records, this guide provides an in-depth understanding of local factors that drive the success of exotic species. It connects species-specific information to conservation issues as it explores human causes of exotic and invasive establishment. The book also includes eight invited essays which provide regional perspectives on scientific, economic, and management-related aspects of this phenomenon. As ecological pressures on native species and habitats increase, understanding the histories and roles of exotic species is becoming more and more important for conservation efforts. Providing practical identification skills and an awareness of the environmental impacts of these amphibians and reptiles, this indispensable guide equips readers to confront the unusual biodiversity crisis of exotic species.

Handbook of Alien Species in Europe by Delivering Alien Invasive Species Pdf

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.

Conservation of Caribbean Island Herpetofaunas Volume 2: Regional Accounts of the West Indies by Adrian Hailey,Byron Wilson,Julia Horrocks Pdf

Most of the islands of the Caribbean have long histories of herpetological exploration and discovery, and even longer histories of human-mediated environmental degradation. Collectively, they constitute a major biodiversity hotspot – a region rich in endemic species that are threatened with extinction. This two-volume series documents the existing status of herpetofaunas (including sea turtles) of the Caribbean, and highlights conservation needs and efforts. Previous contributions to West Indian herpetology have focused on taxonomy, ecology and evolution, particularly of lizards. This series provides a unique and timely review of the status and conservation of all groups of amphibians and reptiles in the region. This volume provides regional accounts of the islands of the West Indies biogeographic region.

Status of Conservation and Decline of Amphibians by Harold Heatwole,Jodi Rowley Pdf

Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.

The Mandarin Duck by Christopher Lever Pdf

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.
