Book Description
Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region. It is essential to identifying and understanding the ecological role of regional herpetofauna and its conservational importance. It examines the biological origins and diversity of amphibians in North Africa, along with their diverse ecosystems, including deserts, grasslands and subtropical forests. The book features detailed descriptions of the adult and larvae stages of species, such as the North African fire salamander, the common painted frog, Brongersma's toad and the Mediterranean tree frog. This book is a vital resource for herpetology and ecology students and researchers, helping them identify, understand and conserve these amphibians and reptiles in their various habitats across the North African and Mediterranean regions. Presents the only book on research and species recognition of North West African and Mediterranean amphibians and reptiles in all life phases Provides novel, iconographic material about little-known species Features helpful visuals, including ink-drawings, photographs of adult and larvae stages, habitat photographs and distributional maps

Book Description
This book draws together a wide range of papers from researchers around the world that address the conservation and biodiversity of vertebrates, particularly those in terrestrial habitats. Collectively, the papers provide a snap-shot of the types of studies and actions being taken in vertebrate conservation and provide topical examples that will make the volume especially valuable for use in conservation biology courses.

Book Description
The taxonomy and systematics of European reptiles and amphibians have changed a lot in recent years, yet there is no modern, up-to-date field guide available that comprehensively covers all the species. The last illustrated field guide to European reptiles and amphibians was first published 38 years ago, and remains oudated despite occasional reprints and new editions. This major new field guide addresses this deficiency. A total of 219 species are covered in detail, with a focus on identification and geographical variation; species texts also cover distribution, habitat and behaviour. Superb colour illustrations by talented artist Ilian Velikov depict every species and all major variations, and colour photographs are also included for most species. This groundbreaking new guide will become the definitive field reference for these two groups of animals. It includes: - Over 370 colour artworks and 200 colour photographs - 155 accurate and up-to-date distribution maps - Easy-to-use keys and tables to help with swift species identification

Book Description
This beautifully illustrated photographic field guide is the first to focus on the identification of the fascinating, diverse and unique wildlife of Madeira and the Canary Islands--featuring the birds, mammals, reptiles, amphibians, butterflies and dragonflies that are most likely to be seen. Richly illustrated introductory sections cover the key wildlife sites to visit on each of the islands and provide an overview of the islands' geography, climate, habitat types and current conservation efforts. Stunning colour photographs highlight the key identification features of each species, and the accompanying text covers status, habitat preference, behaviour and, where appropriate, calls. The guide also features an up-to-date distribution map for each species. Complete with an attractive, user-friendly design, this is a must-have guide for all visitors to these magical islands. A beautifully designed and illustrated photographic field guide to the wildlife of Madeira and the Canary Islands Highlights the islands' unique native species and their conservation status Covers all birds, land and marine mammals, reptiles, amphibians, butterflies and dragonflies that are likely to be seen Features richly illustrated introductory sections on key sites to visit on each of the islands, covering their geography, climate, habitats and conservation Includes distribution maps for all species, as well as information on occurrence, status, habitat preference, behaviour and calls

Book Description
Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

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.

Book Description
"Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.
