This handbook is the first complete guide to the herpetofauna of northeast Africa, covering seven countries - Djibouti, Egypt, Ethiopia, Eritrea, Somalia, South Sudan and Sudan. It contains keys, comprehensive descriptions, maps of all species and photographs of virtually all species known from the region, including 114 species of amphibians and more than 460 species of reptiles. It is an essential tool for herpetologists and conservationists involved with any aspect of the African herpetofauna, and for museums and specialist libraries. Comprehensive and written by the world's leading experts in the field, this is the first book ever written on these animals.

This is a lightweight and portable guide, partly adapted from the popular and highly acclaimed A Field Guide to the Reptiles of East Africa by the same authors. Covering the most prominent 150 reptiles and 80 amphibians found in the region (Kenya, Tanzania, Uganda, Rwanda and Burundi), with concise text, photograph and map for each, this is a convenient and attractive pocket guide for a diverse and often conspicuous and attractive group of animals.

Much has happened in the 19 years since the publication of the first edition of Reptiles and Amphibians: Self-Assessment Color Review. Many more scientists and clinicians have taken an interest in reptiles and amphibians, novel radiographic techniques have been developed, and veterinary surgeons have devised operative solutions to numerous serious conditions in both reptiles and amphibians. The time is right for an expanded second edition that covers these developments and more. See What's in the Second Edition: More than 230 new and revised reptile and amphibian cases, illustrated in color Case studies with answers that fully explore the disease or disorder in question Case selection based on common reptilian and amphibian species kept as pets or study animals Written by a foremost authority, this book presents more than 230 cases and questions at different levels of expertise, with detailed explanatory answers. The cases appear in random order, just as they would in real life, and enable you-by solving the clinical puzzle-to make differential diagnoses, treatment plans, and prognoses. The color review includes a wealth of problem-oriented information of value-and enjoyment-for formal and informal training and continuing education.

Reproductive Biology and Phylogeny of Lizards and Tuatara is a remarkable compendium of chapters written by the world's leading experts from over four continents. The book begins with a chapter recounting historical discoveries in reproductive biology and a review of phylogenetics and up-to-date hypotheses concerning evolutionary relationships among lizards. Following these chapters are detailed reviews with additional new data concerning chemical communication, sexual selection, reproductive cues, female reproductive anatomy, female reproductive cycles, oogenesis, parthenogenesis, male reproductive anatomy, male reproductive cycles, spermatogenesis, reproductive investment, viviparity and placentation, multiple paternity, and parental care. The book culminates in two chapters on tuatara reproduction giving unique insight into evolutionary patterns in reproductive biology in squamates and tuatara. This is an essential resource for anyone studying reproduction in reptiles and/or vertebrates and offers a fascinating read for those interested in reproductive biology.

An indispensable manual for conservationists throughout the UK and much of mainland Europe. It provides conservation guidance on the twelve non-marine amphibian and reptile species native to the British Isles. It covers a wide range of issues, from advice on surveying to reintroductions. Reprint edition of 1861074506 published in 1998.

Offering coverage of a wide range of topics on snake reproduction and phylogeny, this comprehensive book discusses everything from primordial germ migration in developing embryos to semelparity (death after reproduction) in the aspic viper. Beginning with a review of the history of snake reproductive studies, it presents new findings on development, placentation, spermatogenesis, male and female reproductive anatomy, hormonal control of reproduction, reproductive cycles, sex pheromones, and parental care. An indispensible reference, this book offers comparative chapters on snake phylognetics examining morphological characteristics alongside strictly molecular concerns. It is rife with illustrations and color plates.

Featuring in-depth contributions from an international team of experts, the Biology of Turtles provides the first comprehensive review of the Testudinata. The book starts with the premise that the structure of turtles is particularly interesting and best understood within the context of their development, novelty, functional diversity, and evolution. It provides a robust discussion of the development and diversity of the shell. The book also explores the turtle body plan, its physiological and ecological consequences, evolutionary novelties, and their importance. The 200 illustrations found throughout the text enhance the chapters combine with color illustrations of the development of the shell, aspects of bone structural diversity, growth, and skeletochronology, to make this book an unparalleled resource. The volume concludes with a thoughtful discussion of the more than century long debate on the origins of turtles and the reasons why our understanding of the phylogenic origins and evolution of turtles remains tentative. Currently available books on this subject are woefully out of date and no overall review of Testudinata has been undertaken...until now. Each chapter represents a milestone in synthesizing a wide range of available information on specific subjects. The book's challenge: look both inside and outside the shell to build a clearer understanding of the diversity and evolution of turtles.

Southern Africa is home to a diverse reptile fauna of more than 600 species. Of these, nearly 70% are endemic to the region, being found nowhere else.

The extended continental South American turtle record (Norian to Lujanian) allows us to follow the evolution of this reptile clade from its origins. Several significant stem turtle taxa such as: Palaeochersis talampayensis and Condorchelys antiqua provide information on the first steps of turtle evolution. Others such as: Chubutemys copelloi or Patagoniaemys gasparinae provide clues to the origin of the bizarre horned tortoises of the clade Meiolaniidae. The panpleurodiran species such as Notoemys laticentralis or Notoemys zapatocaensis shed light on the origin of modern pleurodiran turtles. This book explores aquatic and terrestrial cryptodiran turtles, South Gondwana pleurodiran turtles, North Gondwana pleurodiran turtles; Meiolaniforms and early differentiation of Mesozoic turtles.

This book provides a brief description of the ecology and natural history of sixteen amphibians, eight snakes and lizards and the Chelonia species found in the temperate climatic region of Europe (North-west Europe). The book commences with an introduction to the biology of amphibians and reptiles and describes the differences between the main groups. The main ecological adaptations are discussed and there is particular mention that it is erroneous to refer to amphibians and reptiles as cold blooded. There is also the suggestion that the colour of an amphibian or reptile may not necessarily mean anything in terms of the animal's thermal properties. For each species there is a brief account of the following: the etymology or origin of the name of the species, reference to early accounts of the species, taxonomy, protection, general description, distribution and habitat, seasonal movements and behaviour, vagility and population ecology, feeding ecology, thermal ecology, reproduction, growth and development, ge

This groundbreaking new guide is an authoritative field reference for these two groups of animals. 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. 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

In April 2007, eleven leatherback turtles captured the imagination of the public worldwide as they "raced" from Costa Rica toward the Galapagos Islands. Known as the Great Turtle Race, this event tracked these critically endangered sea turtles, drawing attention to their fragile status and generating data on the turtles vital to efforts to study and protect them.

But the Great Turtle Race is just one of many tools marine conservationists use to inform people about the status, biology, and lives of the seven sea turtle species. Due to human actions, once-plentiful sea turtle population levels plummeted throughout much of the twentieth century, stabilizing somewhat only after Archie Carr and Jacques Cousteau popularized their plight. With "Saving Sea Turtles," award-winning author James R. Spotila picks up where Carr and Cousteau left off, going inside the modern-day conservation movement to tell the tales of today's sea turtle conservationists. He provides a complete overview of sea turtle biology and life cycles, discusses the human and natural world threats they face, and examines the new methods and technologies humans are using to save them. Throughout, Spotila dots the narrative with stories of real-life heroes who risk life and limb to understand, track, and conserve sea turtles across the globe.

Spotila has been at the forefront of sea turtle research and conservation for decades. His inspirational story of dedicated individuals, creative endeavors, and adventure reveals what is being done and what else we must do in order to ensure that these fascinating animals continue swimming in the oceans.

The definitive resource for finding, identifying, and conserving Maryland's amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity-and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.

Chameleons are fascinating creatures: they almost always evoke in people a strong response, be it delight, wonder or fear.

Chameleons of Southern Africa explores this interesting group of lizards and discusses their strange and unusual, sometimes unnerving, characteristics. It presents an overview of all types of chameleons (of which there are up to 160 species in total, worldwide), their history, geographic distribution (restricted mainly to Madagascar and Africa), reproduction, behaviour and their relationships to each other.

It also contains a clear identification guide to all southern African species - some 25 have been identified to date - together with distribution maps and colourful photographs of their many features and guises. For interested students, gardeners, naturalists and even just the curious, Chameleons of Southern Africa is an essential guide to these intriguing lizards.

South Africa has an inordinate wealth of plants and animals. It is a country of superlatives with an entire floral kingdom occurring within its borders. With a land surface area of only 2 per cent of the global landmass, it contains 10 per cent of the world's plants and between 6 and 7 per cent of the world's mammals, birds and reptiles. Not only does South Africa boast the greatest number of species of land tortoises of any place on Earth, it ranks fifth in the world with regard to overall number of reptile species. Such an array of reptiles, which at last count numbered 363 species, with more being described annually, shows an incredible range of adaptations enabling these remarkable creatures to live in extremes of climate from the high mountains to desert, from coast to coast and some even adapting to an urban environment. Despite this, the daily lives of most reptile species remain a closed book. Many species are cryptic, preferring not to be seen, while others display amongst the brightest colours in the animal kingdom. They range from very small species weighing less than a gram to the giant Nile crocodile, which may achieve a mass of 1 000 kg, and include some of the most poisonous species on the planet. It is indeed a treasure house. Remarkable Reptiles offers a glimpse into the fascinating world of snakes, lizards, chameleons, tortoises, terrapins and crocodiles and hopes to provide a greater insight into the behaviour of these often maligned animals. Many reptiles, especially snakes, receive unjust treatment because of attacks on humans, while anthropogenic causes, which are far more lethal, tend to be less emphasised. Hopefully this book will contribute to, and instil respect and interest in the remarkable diversity of reptiles with which South Africa has been blessed.

How did the zebra really get its stripes, and the giraffe its long neck? What is the science behind camel humps, leopard spots, and other animal oddities? Such questions have fascinated us for centuries, but the expanding field of evo-devo (evolutionary developmental biology) is now providing, for the first time, a wealth of insights and answers. Taking inspiration from Kipling's 'Just So Stories', this book weaves emerging insights from evo-devo into a narrative that provides startling explanations for the origin and evolution of traits across the animal kingdom. Held's unique and engaging style makes this narrative both enlightening and entertaining, guiding students and researchers through even complex concepts and encouraging a fuller understanding of the latest developments in the field. The first five chapters cover the first bilaterally symmetric animals, flies, butterflies, snakes, and cheetahs. A final chapter surveys recent results about a menagerie of other animals.
