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.

Book Description
Palaeobatrachidae are an extinct family of frogs whose earliest members are recorded from the Middle Eocene (Geiseltal, Messel, Germany), almost 50 million years ago, although there are indications that they appeared as early as before the Cretaceous mass extinction event and survived almost to our times. Their last survivors are recorded from the Middle Pleistocene, less than 0.5 million years ago, such that they were contemporaries of Neanderthal man. Their last fossil evidence is from the regions that were adjacent to the Pleistocene continental glacier. Like today's pipid frogs (e.g. Xenopus), they were obligate water dwellers, not able to make long excursions onto dry land. Without exaggerating, they literally died out frozen in their ponds. Permanent life in water has a uniforming effect. This is why they all looked similar to one another, which is a source of difficulty for taxonomists. On the other hand, one cannot overlook features they have in common with pipids, restricted to the southern hemisphere. Palaeobatrachus and Xenopus are undoubtedly related, but when and why ancestors of Palaeobatrachus immigrated to the western part of northern Eurasia but not to its eastern part and not to North America remains a puzzling question. Thus, being acquainted with Palaeobatrachus means to be invited on an excursion not only into comparative anatomy, but also into paleogeography and many other fields of palaeontology. Last but not least, Palaeobatrachus was the first fossil frog scientifically described, as early as in 1831. Since that time, many excavation sites from which original material came have ceased to exist; thus there is no possibility that further material will be recovered. What is now deposited in scientific collections is the unique and limited source of data for future comparative studies. This is one of the main reasons why this rich illustrated review was published.

Book Description
The book describes each amphibian with its alternate name, its main characteristics, biological data, population status, and geographic distribution. Each entry is accompanied by plenty of figures and colored pictures of the amphibian and its geographic distribution map. These illustrate China's amphibian species diversity and the latest research findings. It is the most comprehensive summary of China's amphibians. The text and picture combination aids species identification and comparison, and is valuable for the in-depth study of their phylogeny. Its detailed, comprehensive and illustrative descriptions help to identify amphibian species, and have important academic significance for further surveys and research on amphibian numbers, animal protection and the development of protective measures as well as quarantine in customs. It provides important information for research units concerned with amphibians both in China, and the rest of the world, and also for animal protection and law enforcement agencies. Professor Liang Fei, was formerly the director of the department of the herpetological research at Chengdu Institute of Biology, the Chinese Academy of Sciences, Chengdu, China; Professor Changyuan Ye works at Chengdu Institute of Biology, the Chinese Academy of Sciences, Chengdu, China;

Book Description
Easy-to-use, comprehensive reference covering the less common species encountered in general veterinary practice Handbook of Exotic Pet Medicine provides easy-to-access, detailed information on a wide variety of exotic species that can be encountered in general veterinary practice. Offering excellent coverage of topics such as basic techniques, preventative health measures, and a formulary for each species, each chapter uses the same easy-to-follow format so that users can find information quickly while working in the clinic. Presented in full colour, with over 400 photographs, the book gives small animal practitioners the confidence to handle and treat more familiar pets such as budgerigars, African grey parrots, bearded dragons, corn snakes, tortoises, pygmy hedgehogs, hamsters and rats. Other species that may be presented less frequently including skunks, marmosets, sugar gliders, koi carp, chameleons and terrapins are also covered in detail to enable clinicians to quickly access relevant information. Provides comprehensive coverage of many exotic pet species that veterinarians may encounter in general practice situations Presents evidence-based discussions of topics including biological parameters, husbandry, clinical evaluation, hospitalization requirements, common medical and surgical conditions, radiographic imaging, and more The Handbook of Exotic Pet Medicine is an ideal one-stop reference for the busy general practitioner seeing the occasional exotic animal, veterinary surgeons with an established exotic animal caseload, veterinary students and veterinary nurses wishing to further their knowledge.

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.

Book Description
The book compiles case studies regarding the biodiversity research and monitoring program of Andean species and habitats carefully chosen as indicators to assess the short- and long-term effects of a linear disturbance: the PERU LNG pipeline. Set in a scientifically unexplored region of the Andes, Monitoring Biodiversity clearly articulates the Smithsonian-led conceptual framework for the implementation in the field by scientists. It addresses scientific and conservation questions addressed by the research protocols, the experimental design, and data gathering. Moreover, the book covers a gap on how to integrate biodiversity research, monitoring, and conservation into sustainable development projects of national and international interest. The text is presented in both English and Spanish.
