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

This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and tracking, fish species recognition and analysis, a large SQL database to record the results and an efficient retrieval mechanism. Novel user interface mechanisms were developed to provide easy access for marine ecologists, who wanted to explore the dataset. The book is a useful resource for system builders, as it gives an overview of the many new methods that were created to build the Fish4Knowledge system in a manner that also allows readers to see how all the components fit together.

This volume celebrates the contributions of Dr. Eugene Gaffney to the study of turtles, through a diverse and complementary collection of papers that showcases the latest research on one of the most intriguing groups of reptiles. A mix of focused and review papers deals with numerous aspects of the evolutionary history of turtles, including embryonic development, origins, early diversification, phylogenetic relationships, and biogeography. Moreover it includes reports on important but poorly understood fossil turtle assemblages, provides historical perspectives on turtle research, and documents disease and variation in turtles. With its broad scope, which includes descriptions of material and new taxa from Australia, Asia, and Europe, as well as North and South America, this work will be an essential resource for anyone interested in the morphology and evolution of turtles. "This volume's breadth of time, geography, and taxonomic coverage makes it a major contribution to the field and a 'must have' for all vertebrate paleontologists.", James F. Parham, California State University, CA, USA "A comprehensive and sweeping overview of turtle evolution by the top experts in the field that will interest everyone curious about these unique reptiles." Jason S. Anderson, University of Calgary, Canada "An invaluable addition to the literature that covers the full spectrum of approaches toward understanding the evolution of these noble creatures." Ann C. Burke, Wesleyan University, CT , USA "A truly comprehensive volume that both the student of fossil turtles, as well as the general reader interested in these enigmatic creatures, will find fascinating." Tyler Lyson, Yale University, CT, USA

New species of animal and plant are being discovered all the time. When this happens, the new species has to be given a scientific, Latin name in addition to any common, vernacular name. In either case the species may be named after a person, often the discoverer but sometimes an individual they wished to honour or perhaps were staying with at the time the discovery was made. Species names related to a person are 'eponyms'. Many scientific names are allusive, esoteric and even humorous, so an eponym dictionary is a valuable resource for anyone, amateur or professional, who wants to decipher the meaning and glimpse the history of a species name. Sometimes a name refers not to a person but to a fictional character or mythological figure. The Forest Stubfoot Toad Atelopus farci is named after the FARC, a Colombian guerrilla army who found refuge in the toad's habitat and thereby, it is claimed, protected it. Hoipollo's Bubble-nest Frog Pseudophilautus hoipolloi was named after the Greek for 'the many', but someone assumed the reference was to a Dr Hoipollo. Meanwhile, the man who has everything will never refuse an eponym: Sting's Treefrog Dendropsophus stingi is named after the rock musician, in honour of his 'commitment and efforts to save the rainforest'. Following the success of their Eponym Dictionary of Reptiles, the authors have joined forces to give amphibians a similar treatment. They have tracked down 1,609 honoured individuals and composed for each a brief, pithy biography. In some cases these are a reminder of the courage of scientists whose dedicated research in remote locations exposed them to disease and even violent death. The eponym ensures that their memory will survive, aided by reference works such as this highly readable dictionary. Altogether 2,668 amphibians are listed.

This title now includes 30 additional species. Revised and updated to reflect the most current science, and including 30 new species, this authoritative and comprehensive volume is the definitive guide to the amphibians and reptiles of the Carolinas and Virginia. The new edition features 189 species of salamanders, frogs, crocodilians, turtles, lizards, and snakes, with updated color photographs, descriptions, and distribution maps for each species. It is an indispensable guide for zoologists, amateur naturalists, environmentalists, backpackers, campers, hikers, and everyone interested in the outdoors.

This book focuses on the first vertebrates to conquer land and their long journey to become fully independent from the water. It traces the origin of tetrapod features and tries to explain how and why they transformed into organs that permit life on land. Although the major frame of the topic lies in the past 370 million years and necessarily deals with many fossils, it is far from restricted to paleontology. The aim is to achieve a comprehensive picture of amphibian evolution. It focuses on major questions in current paleobiology: how diverse were the early tetrapods? In which environments did they live, and how did they come to be preserved? What do we know about the soft body of extinct amphibians, and what does that tell us about the evolution of crucial organs during the transition to land? How did early amphibians develop and grow, and which were the major factors of their evolution? The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, and is edited by Professor Mike Benton, University of Bristol. Books in the series provide a summary of the current state of knowledge, a trusted route into the primary literature, and will act as pointers for future directions for research. As well as volumes on individual groups, the series will also deal with topics that have a cross-cutting relevance, such as the evolution of significant ecosystems, particular key times and events in the history of life, climate change, and the application of a new techniques such as molecular palaeontology. The books are written by leading international experts and will be pitched at a level suitable for advanced undergraduates, postgraduates, and researchers in both the paleontological and biological sciences.

Boas of the West Indies is a comprehensive survey of boid snakes, commonly known as boas, found on the islands of the Lucayan Archipelago, the Greater Antilles, and the Lesser Antilles. Bringing together the expertise of leading herpetologists R. Graham Reynolds, Robert W. Henderson, Luis M. Diaz, Tomas Michel Rodriguez, and Alberto R. Puente-Rolon, this volume synthesizes established knowledge and new findings on the evolutionary biology, natural history, and conservation statuses of these iconic snakes. One of the most ecologically diverse snake families, boas have inhabited the West Indies for millions of years. From the Cuban boa, which in many folk legends may grow to over twice a person's height, to the Hispaniolan vineboa, discovered only in 2020 and known to measure less than a meter long, Boas of the West Indies examines the eighteen species extant on these islands along with several others now extinct. Species accounts include details such as phenotypic traits, distribution, and behavior. Introductory chapters discuss the history of human-boa interaction, differences between West Indian and neotropical mainland boids, current conservation efforts, and more. Illustrated with over a hundred color photographs and range maps, Boas of the West Indies is a benchmark reference for herpetologists, conservationists, and snake hobbyists that expands our knowledge of-and celebrates-these fascinating creatures so integral to the ecology of these islands.

In a Panamanian pond, male tungara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Tungara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the tungara frog's calls.

"Evidence bases for conservation are becoming increasingly important to convince landowners and politicians of the need to take action in defence of species and habitats all around the world. A valuable feature of this book is its emphasis on collecting and analysing such essential information." Trevor Beebee, Phyllomedusa Amphibians are among the most globally endangered groups of vertebrates with more than one-third of species being assessed as declining or threatened. Often, amphibian declines can be attributed to a suite of interacting factors, many of which are human in origin, but further information is needed to elaborate the key causes and to discover ways of reversing declines. Robust surveys provide vital ecological and biological data on amphibian populations, and underpin the decisions made to protect species and reverse their declines. Ongoing monitoring informs land managers and decision makers about whether they are taking the right action. This book is designed to help you carry out amphibian surveying and monitoring so that the results of your surveys can be used effectively. Part 1 introduces amphibians: order Anura (frogs and toads); Caudata (newts and salamanders); and order Gymnophonia (caecilians). Part 2 is essential reading before you start surveying. It introduces the different types of survey and monitoring programmes and discusses survey aims and resources. It contains chapters on collecting and handling survey data; survey permissions and licencing; health and safety, and biosecurity; and handling amphibians. Part 3 discusses everything you need to know during your survey, and provides a detailed look at amphibian survey methods. Part 4 covers presenting and using your survey's data to best effect. A useful resources section is also provided, with example survey forms and details of additional information resources that will optimize the impacts of your surveys. Key amphibian survey techniques are discussed with reference to published examples of successful surveys - so you'll be able to choose what's right for your situation. Tips on optimizing your survey effort and handling amphibians in the field are also included. Whether carrying out a student expedition project or seeking information to support the management of a protected area, this book contains essential advice from an amphibian ecologist who has encountered the same sorts of decisions you'll face when planning your surveys.

Amphibians are the extant descendants of the first vertebrate class to successfully colonize terrestrial environments; hence they occupy a unique position between fish and reptiles. Amphibian skin provides essentially no resistance to evaporative water loss, and consequently daily water turnover rates are an order of magnitude greater than in other terrestrial vertebrate groups. This has led to a suite of physiological, morphological and behavioural adaptations that have allowed a successful terrestrial existence in spite of this apparently spendthrift water retention strategy.
Ecological and Environmental Physiology of Amphibians provides a synthesis of current research on the comparative physiology of amphibians with a particular emphasis on water balance. It adopts a strong environmental perspective and includes a wealth of information on ecology, phylogeny and development. As with other books in the Ecological and Environmental Physiology Series, the emphasis in this book is on the unique physiological characteristics of the amphibians, although the latest experimental techniques and future research directions are also considered. This accessible text is suitable for both graduate students and researchers in the fields of amphibian comparative physiology and physiological ecology, including specialist courses in amphibian ecology. It will also be of value and use to the many professional herpetologists requiring a concise overview of the topic.

Through its emphasis on recent research, its many summary tables, and its bibliography of more than 4,000 entries, this first modern, synthetic treatment of comparative amphibian environmental physiology emerges as "the" definitive reference for the field. Forty internationally respected experts review the primary data, examine current research trends, and identify productive avenues for future research.
