Naturalized Reptiles and Amphibians of the World


Book Description

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.




Reptiles and Amphibians of the Pacific Islands


Book Description

The Pacific is not only the worldÕs 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 Gal‡pagos 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.




Biological invaders in inland waters: Profiles, distribution, and threats


Book Description

Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.




Handbook of Alien Species in Europe


Book Description

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.




Restoring the Oceanic Island Ecosystem


Book Description

Loss of biodiversity on tropical and subtropical oceanic islands is one of the most pressing conservation issues. These oceanic islands are well known for their unique fauna and ? ora, which evolved over long periods in isolation from external perturbation. However, the maj- ity of these islands in the Paci? c were eventually settled by Polynesians and then by Europeans; by about 200 years ago, only a few island groups remained untouched. The Bonin Islands are one of these groups. The Bonin Island group is one of the most remote in the world. The islands are located 1,000 km south of Japan off the eastern fringe of Eurasia. They were ? rst discovered by the Japanese in 1670, settled by Westerners from Hawaii in 1830, and ? nally recognized as a Japanese territory in 1862 on condition that previous settlers would be protected and allowed to remain with full rights. Because of this complicated history, the Bonins have two names.




Managing Australia's Pest Animals


Book Description

Pest animals are but one of many factors that influence the desired outcome from managing natural resource based systems, whether for production or conservation purposes. Others include diseases, weeds, financial resources, weather and fire management. To be effective, an integrated and systematic approach is required, and the principles and strategic approach outlined in this book can also be used to plan and manage the damage due to other factors. Managing Australia's Pest Animals includes case studies of successful and unsuccessful pest management strategies and covers a range of topics, including the history of pest management, current best practice principles, and guidelines for planning and applying strategic pest management approaches to effectively reduce pest damage. This book is the first clear and comprehensive guide to best practice pest management in Australia and will benefit students and trainers of pest managers, landholders, people involved in natural resource management, and industry and government pest management staff. This book will be of great benefit to students and trainers of pest managers, landholders, pest management staff, or volunteers working in natural resource management, including private and public land managers, parks and wildlife staff, pest management agencies, local councils, Landcare and catchment management groups and private pest contractors.




Conservation of Caribbean Island Herpetofaunas Volume 1: Conservation Biology and the Wider Caribbean


Book Description

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 introduces the issues particularly affecting Caribbean herpetofaunas, and gives an overview of evolutionary and taxonomic patterns influencing their conservation.




Status of Conservation and Decline of Amphibians


Book Description

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.




Conservation of Caribbean Island Herpetofaunas Volume 2: Regional Accounts of the West Indies


Book Description

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: Anguilla; Antigua and Barbuda; The Bahamas; Barbados; The British Virgin Islands; The Cayman Islands; The Commonwealth of Dominica; The Dominican Republic; The Dutch Windward Islands of St. Eustatius, Saba and St. Maarten; The French West Indies; Grenada; The Grenadines; Jamaica; Martinique; Puerto Rico; St. Vincent; The Turks and Caicos Islands; The United States Virgin Islands. Each account discusses the conservation problems of the herpetofauna and their solutions, in a region made up of islands of diverse ecology and political systems. The book will be useful to biologists and conservationists working in or visiting the Caribbean, and internationally as a summary of the current situation in the region.




Non-native Species and Their Role in the Environment


Book Description

The young field of invasion biology - initially a branch of ecology and conservation biology - has greatly expanded, particularly in the last two and a half decades or so. As a result, the potential negative effects of introduced species have been widely advertised and sometimes, perhaps, overemphasized. This book attempts to restore some balance to the current debate over the role of non-native species, by offering a broader perspective, and taking a longer term, evolutionary look at these species and their impact in their new environments. The relatively arbitrary nature of terms such as "native" and "non-native", and the rather inconsistent ways in which such terms are applied to biological species, as well as the subjective boundaries of so-called "native ranges" are analyzed. The role of non-native species in their new environments can be considerably more complex than the anti-introduced species information would often suggest. Thus, the more positive and nuanced perspective on introduced species and their impact offered in this book is much needed and long overdue.
