Book Description

Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Book Description

What makes a frog an amphibian but a snake a reptile? Both classes may lay eggs, but they have different skin coverings and breathe in different ways. Pages of fun facts will help kids identify each animal in the class like a pro after reading the fourth book in Arbordale’s Compare and Contrast series. Similar to Polar Bears and Penguins, Clouds and Trees; Amphibians and Reptiles uses stunning photographs and simple non-fiction text to get kids thinking about the similarities and differences between these two animal classes.

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 is the first book on ranaviruses. Ranaviruses are double-stranded DNA viruses that cause hemorrhagic disease in amphibians, reptiles, and fish. They have caused mass die-offs of ectothermic vertebrates in wild and captive populations around the globe. There is evidence that this pathogen is emerging and responsible for population declines in certain locations. Considering that amphibians and freshwater turtles are suitable hosts and the most imperiled vertebrate taxa in the world, ranaviruses can have significant impacts on biodiversity and ecosystem function. Additionally, many fish that are raised in aquaculture facilities and traded internationally are suitable hosts; thus, the potential economic impact of ranaviruses is significant. Ranaviruses also serve as a model for replication and gene function of large double-stranded DNA viruses. There is an urgent need to assemble the contemporary information on ranaviruses and provide guidance on how to assess their threats in populations. Through the Global Ranavirus Consortium, 24 experts from six countries were organize to write this volume, the first book on ranaviruses. The book begins with a discussion on the global extent of ranaviruses, case histories of infection and disease in ectothermic vertebrates, and current phylogeny. Basic principles of ranavirus ecology and evolution are covered next, with a focus on host-pathogen interactions and how the virus emerges in its environment. There are two chapters that will discuss the molecular biology of ranaviruses, host response to infection, and the genes responsible for immune system evasion. One chapter establishes standards for testing for infection and diagnosing ranaviral disease. The book ends by providing guidance on how to design ranavirus surveillance studies and analyze data to determine risk, and discussing the role of the Global Ranavirus Consortium in organizing research and outreach activities.

Book Description

The paleontologist and professor of anatomy who co-discovered Tiktaalik, the “fish with hands,” tells a “compelling scientific adventure story that will change forever how you understand what it means to be human” (Oliver Sacks). By examining fossils and DNA, he shows us that our hands actually resemble fish fins, our heads are organized like long-extinct jawless fish, and major parts of our genomes look and function like those of worms and bacteria. Your Inner Fish makes us look at ourselves and our world in an illuminating new light. This is science writing at its finest—enlightening, accessible and told with irresistible enthusiasm.

Book Description

The Teeth of Non-Mammalian Vertebrates is the first comprehensive publication devoted to the teeth and dentitions of living fishes, amphibians and reptiles. The book presents a comprehensive survey of the amazing variety of tooth forms among non-mammalian vertebrates, based on descriptions of approximately 400 species belonging to about 160 families. The text is lavishly illustrated with more than 600 high-quality color and monochrome photographs of specimens gathered from top museums and research workers from around the world, supplemented by radiographs and micro-CT images. This stimulating work discusses the functional morphology of feeding, the attachment of teeth, and the relationship of tooth form to function, with each chapter accompanied by a comprehensive, up-to-date reference list. Following the descriptions of the teeth and dentitions in each class, four chapters review current topics with considerable research activity: tooth development; tooth replacement; and the structure, formation and evolution of the dental hard tissues. This timely book, authored by internationally recognized teachers and researchers in the field, also reflects the resurgence of interest in the dentitions of non-mammalian vertebrates as experimental systems to help understand genetic changes in evolution of teeth and jaws. - Features more than 600 images, including numerous high-quality photographs from internationally-recognized researchers and world class collections - Offers guidance on tooth morphology for classification and evolution of vertebrates - Provides detailed coverage of the dentition of all living groups of non-mammalian vertebrates

Book Description

"The Bartlett's provide a convenient identification guide and reference manual for the reptiles and amphibians most likely to be encountered by visitors to the Amazon basin. It will be of great interest to ecotourists and herpetological hobbyists, and the basic natural history information will be useful to professional biologists who are not specialists in the taxa covered in the book."--Paul E. Moler, Florida Fish and Wildlife Conservation Commission Though travel to the Amazon Basin once was accessible only to the most intrepid explorer, today the region is a popular destination for scores of ecotourists, visitors who are likely to observe 50 species of reptiles and amphibians in just a weeklong trip. Until publication of this illustrated field guide, no book has been available to help identify these delightful, stunning, and sometimes venomous creatures. This handbook offers a colorful, easy-to-use guide to more than 250 of the snakes, lizards, turtles, frogs, and salamanders common to the Amazonian regions of Peru, Brazil, Bolivia, and Colombia. From brightly colored frogs so small they fit on a thumbnail to large poisonous snakes camouflaged by green and brown patterned skin, it features all the more frequently seen species as well as types that are less common, and it also provides basic natural history information. Clear close-up photos accompany text that describes appearance, range, size, and color and lists similar species. For many years the authors have led tours to the rainforest. They travel remote rivers on small boats, bunk in tents pitched on sleeping platforms, and walk seldom-trodden trails, usually finding a herpetologic species new to them on each trip. At times, they were hard-pressed to identify the species they photographed; their fellow travelers have found the task even more difficult. For those who want to attach names and information to their natural surroundings, this new field guide will open up the beautiful and mysterious world of herpetofauna. In addition, students of rainforest ecology will find useful information about the infinite variety of rainforest adaptations, and hobbyists will appreciate hard-to-find information about imported specimens. R.D. Bartlett is the author of many books, including In Search of Reptiles and Amphibians and Popular Boas and Pythons, and has published more than 500 articles about herpetology in such magazines as Tropical Fish Hobbyist, Reptiles, and Reptile and Amphibian. Patricia Bartlett is the coauthor with R.D. Bartlett of numerous books, including A Field Guide to Florida Reptiles and Amphibians. Together they have led herpetology photography tours to many areas of the Amazon Basin.
