A "New York Times "Notable Book
Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series is published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world. This volume, Part 4 in the series, is concerned with Southern Europe (Italy, Malta, Croatia, Slovenia, Serbia, Montenegro, Bosnia and Herzegovina, Macedonia, Albania, Greece, Romania, Hungary, Bulgaria, Turkey, and Cyprus). Each chapter has been written by experts from each country, describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites, threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climatic change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programs, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.
Amphibian skin has, over the last century, proven to contain a treasure-trove of biologically active compounds. Since that time further investigation has added hundreds of such compounds to the list of active substances from amphibian skin. Peptides, proteins, bufadienolides steroids and alkaloids (tetrodotoxins, biogenic amines and lipophilic alkaloids) represent the main compounds found in the amphibian skin. This book discusses the anatomy of amphibians. It also provides topics on the ecological significant and conservation strategies of these marine animals.
In this book the authors present current research in the study of frogs. Frog's neuromuscular junction (NMJ) is a classic and favourite object which have played a leading role in developing understanding of the basic mechanisms of synaptic transmission and secretion of neuromediator. The genetic diversity, neural development and ecological implications of frogs are examined throughout the book. Some of the topics the authors discuss in this compilation include poison storage and maturation in serous cutaneous glands of anurans; a mini review of the suppression of anuran metamorphosis by synthetic chemical compounds; mechanisms of suprathreshold excitation of a frog tectal neuron column by discharge of a single moving edge or darkness detector and their relation to a frog escape reactions; behavioral, ecological, and evolutionary aspects of diversity in frog colour patterns; physiological features of blood's system of frogs rana ridibuda pall; and presynaptic voltage-dependent calcium channels at the frog neurmuscular junction.
Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series will be published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world; this Part 3 is concerned with Western Europe (Britain, Ireland, The Netherlands, Belgium, France, Spain and Portugal). Experts from each country contribute a chapter describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites (also covered in a general chapter), threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climate change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programmes, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will therefore provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.
Reef Aquarium Success - Volume 1: Learn How To Maintain A Beautiful Mini-Ocean Environment Within Your Tank" is Volume 1 of the original electronic book "Reef Keeping Basics - Successful Reef Management." To assist in the marketing and promotion of that original book, the author - Eric V. Van Der Hope, decided to publish a paperback version of the book. Also, because the original electonic book comprised over 700 pages & over 300 colorful images, it wasn't cost effective to produce as a single printed book. Thus, "Reef Aquarium Success - Volume 1" has become part 1 of an extremely informative and educational resource.About "Reef Aquarium Success - Volume 1""A Comprehensive Reef Keeping Resource - Written by Hobbyists - For Hobbyists "Do You Want To Maintain A Beautiful Pristine Reef Environment Successfully, While Maintaining Proper Conditions For The Health of Your Tropical Fish, Invertebrates and Corals?Learn to master what it takes to successfully maintain a mini-ocean environment within your home or office Here's just a sample of what's revealed within the pages of "Reef Aquarium Success - Volume 1": Discover what the most important aspect to consider is before even beginning the thought of maintaining your very own mini-reef environment Learn 10 critically important steps to help guarantee your chances of establishing a successful reef tank.You'll get a revealing look at some of the most common mistakes hobbyists make that result in disastrous results.

Host to more than one hundred species of reptiles and amphibians, the Savannah River Site, a 780-square-kilometer tract in South Carolina, is one of the most intensely studied areas of herpetological ecology in the world. This guide is a summary of basic information on the site's richly varied herpetofauna, from their taxonomy and distribution to their behavior and habitats. Keys to identify the adult and larval forms of the site's known species comprise the core of the guide. These keys are supplemented by maps, graphs, and illustrations as well as by information on habitats; population characteristics and distribution; behavior related to movement, feeding, and reproduction; morphology; and techniques for collecting specimens. The guide also includes information about special identification and study problems involving unresolved sighting reports; subspeciation; and venomous, edible, endangered, and introduced species. Finally, a bibliography gives not only the sources referred to in the guide but virtually all studies and reports based on herpetological research conducted at the Savannah River Site. The site-related publications are listed by author but can also be found through an index to the subjects they cover. Guide to the Reptiles and Amphibians of the Savannah River Site is a valuable one-volume introduction to the existing information on herpetofauna at the site and to the countless research opportunities the site still presents. Because it is clearly written and designed and lists most of the reptiles and amphibians found in Georgia and South Carolina, the guide is also useful to wildlife observers--professional and amateur--in those states.
"Assays of assemblages of amphibians and reptiles provide important information on community structure in the tropics. These ectothermic organisms are highly responsive to slight differences in the environment and to seasonal differences, such as patterns of rainfall. Most species seem to have rather restricted home ranges; therefore, data gathered in a restricted area provide much better insight into the requirements of, and potential interactions among, the species in the assemblage." from the IntroductionThe rainforests in the southwestern part of the Amazon Basin in southeastern Peru are home to scores of amphibians and reptiles. Cusco Amazonico is a richly illustrated and comprehensive account of the lives of 151 of these species. William E. Duellman's masterpiece of community ecology includes descriptions of the physical environment and vegetation found in this unique habitat along with syntheses of abundance, mass, feeding, reproductive guilds, and daily and seasonal patterns of activity. Identification keys in English and Spanish precede detailed and illustrated species accounts. Tadpoles of many frogs are described and illustrated.Cusco Amazonico will become a standard reference for herpetologists, tropical biologists, biogeographers, ecologists, and conservationists and stands on its own as a portrait of an animal community in a unique bioregion. The illustrations include 236 color photographs, 121 charts and graphs, 16 maps, 42 line drawings, 2 halftones, and 56 sets of audiospectrograms and waveforms. There are 71 tables."
"This book is an outstanding contribution to our understanding and enjoyment of frogs by an eminent leader in the field of amphibian biology. It is written in an engaging style, which reflects the author's long interest in popularizing natural history subject matter."—Robert C. Stebbins, Emeritus Professor of Zoology and Emeritus Curator in Herpetology, Museum of Vertebrate Zoology, University of California, Berkeley Australia is home to some of the most interesting and unusual frogs in the world and Michael J. Tyler is acknowledged to be the foremost expert on them. This lavishly illustrated new edition of Australian Frogs is the definitive resource on the subject, with updated tables and supplementary text on the fossil record which is vital to historical understanding. Tyler covers the origins, environment, nomenclature, habits, and biology of frogs. Tyler writes conversationally about the amphibian creatures he clearly loves, and his book does not require detailed technical knowledge. He does, however, provide a wealth of information on the ways and needs of Australian frogs in all their fragile variety.
The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date. Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.
Despite their abundance in many parts of North America, salamanders have generally been neglected by all but a few specialists. In this book-first published in 1943-Sherman C. Bishop discusses in a lively but authoritative manner the 126 species and subspecies of salamanders that are known to exist in the United States, Canada, and Baja California.Group by group, Bishop describes salamanders in accounts that give the common and technical names, type of locality, range, habitat, size, anatomical characteristics, color, breeding habits, and relationships-all in a uniform arrangement that makes the handbook especially convenient for studying both living animals and laboratory specimens. His brief introduction surveys the relationships and general habits of salamanders and gives information on collecting and preserving them. In his foreword to the 1994 reprint edition, Edmund D. Brodie, Jr., a specialist on salamanders, updates the taxonomy of the group.
This edited volume explores the various views on the origins of tetrapods-amphibians, reptiles, birds, and mammals-views that agree or differ depending in part on how certain fossil animals are classified and which methodology is used for classification. Eighteen chapters by an international group of paleontologists and neontologists here present current hypotheses, emphasizing the kinds of data needed to answer controversial questions, as well as the variety of solutions that emerge from diferent analyses of the same data set. The book is arranged in five sections, each of which contains an overview essay that either describes the development of various schools of thought regarding the origin of the tetrapod group in question or critically summarizes the arguments presented in the section. The first section addresses the origins of tetrapods as a group, focusing on lobe-finned fishes and early tetrapods. Next is a section dealing with amphbians, followed by one on reptiles. The fourth section concerns avian origins, and the final section treats the origins and early diversification of mammals. With an overall goal of stimulating critical evaluation by the reader rather than providing unequivocal answers, this volume will be of particaular interest to vertebrate paleontologists, evolutionary morphologists, and ichthyological, herpatological, avian, and mammalian systematists.
In this book, the authors gather and present topical research from across the globe in the study of the biology, ecology and uses of frogs. Topics discussed include using frog red blood cells for exploring the ion transport pathways across cellular plasma membranes and their regulation; the significance of retinal glial cells for glutamatergic neural transmission in frog retina; a review of the intraspecific patterns and differences in life-history traits of frog populations living at different altitudes; the peripheral nervous system in the frog as a tool to examine the regulation of the transmission of neuronal information; ecological traits in the Omei treefrog in western China; taxonomic patterns of tadpole behavioural responses to alarm cues and frogs and toads used as bioindicator organisms in pollution studies. |
