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 andsocio-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 extremelydestructive 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 populationsunsupported by, and independent of, mankind.

They change color depending on their mood. They possess uniquely adapted hands and feet distinct from other tetrapods. They feature independently movable eyes. This comprehensive volume delves into these fascinating details and thorough research about one of the most charismatic families of reptiles—Chameleonidae. Written for professional herpetologists, scholars, researchers, and students, this book takes readers on a voyage across time to discover everything that is known about chameleon biology: anatomy, physiology, adaptations, ecology, behavior, biogeography, phylogeny, classification, and conservation. A description of the natural history of chameleons is given, along with the fossil record and typical characteristics of each genus. The state of chameleons in the modern world is also depicted, complete with new information on the most serious threats to these remarkable reptiles.

"The reference source that biologists interested in West Indian herpetofauna have been waiting for."--Steven Reichling, curator, Memphis Zoo "A state-of-the-art compendium. The West Indies is one of the hottest of the world's biodiversity hot spots and will continue to be a focus of ecological research, now invigorated by this definitive synthesis."--S. Blair Hedges, Pennsylvania State University The West Indies have become a major focus for biologists and conservationists. Its herpetofauna is considered one of the richest and most vulnerable in the world. These fragile natural environments are home to many unique animals that occur only on these islands. Loss of habitat, development of scenic areas for a burgeoning tourist industry, and the introduction of invasive species have contributed to an already tenuous situation for many of the region's native species. This volume summarizes the natural history of each of the more than seven hundred species of frogs and reptiles that live in the West Indies. Sure to be the starting point for all future research on West Indian amphibians and reptiles, it will be an essential companion to the biologist contemplating or conducting research in the area.

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 authoritative and eminently readable book relates how the alien vertebrate animals now living in the wild in Britain and Ireland were introduced and naturalized, their status and distribution, and their impact on the local environment. The core of the book describes animals that have been imported deliberately or accidentally and have established populations in the wild, among them the Red-necked Wallaby, Monk Parakeet and African Clawed Toad. There are also sections on feral domesticated species such as feral cats, goats and Reindeer, ephemeral species such as the Canadian Beaver and Mongolian Gerbil, and reintroduced species like the now-thriving Red Kite. Distribution maps show the locations of most of the featured species, and full-colour photographs reveal their amazing diversity.
