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.

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.

Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

The late 20th Century and the early 21st century has been characterized by an unprecedented deterioration of the environment of the earyh and the throes of one of the major extinction events of all time. New diseases have emerged. Unmitigated deforestation,desertation,erosion and salinization of soil,pollution of water and air,and thinning of the UV-protective ozone layer constitute dire ecological threats for life on the planet. This volume contains 12 dynamic chapters reated to amphibian decline; Viral and Bacterial diseases of amphibians,Fungal Diseases; Factors affecting Interspecific variation in susceptibility to Disease ,Digenitic trematodes and their relationship to amphibian declines and deformaties,Amphibian malformations,Ultra Violet-B radiation,pollution,impact of reactive nitrogen, evaluating the impact of pesticides,endocrine disrupting chemicals,role of petrochemicals and heavy metals,acidification,and its effects and climate change.

Study of the osteology of extant forms, primarily morphological in focus but with some chapters stressing development, functionality or phylogeny. Topics include: a comparison of dermal skulls of recent amphibians with those of their palaeozoic ancestors; whole bones of the 3 orders of modern amphibians; salamanders; caecilians; anurans.

Inevitably, overlap occurs when dealing with separate aspects such as behaviour, development and anatomy, that relate to the same function. In this volume, the design was to avoid undue overlap but not to eliminate it altogether. The first chapter provides the morphological background for the rest of the book by describing the anatomy of the amphibian endocrine system. Following chapters treat the various endocrine systems in terms of their function and development as related to particular aspects of amphibian life. Three chapters deal with different aspects of reproduction, including reproductive cycles, breeding behaviour, and the development of secondary sexual characters. Two chapters have a strong developmental emphasis, with treating the role of hormones in metamorphosis and dealing with hormonal regulation of growth. Three chapters deal with hormonal regulation of various day-to-day physiological processes such asmetabolism, osmoregulation and colour change. The book closes with an account of the role of hormones in the immune system of amphibians.

Now reissued in paperback with an updated preface by the authors, Biology of Amphibians remains the standard work in its field.

This book focuses on the impacts of anthropogenic radiation on wildlife and ecosystems and provides an in-depth look at the approaches and available tools we can use to gain information about biological effects of radiation in the environment. The nuclear accidents in Chornobyl in 1986 and Fukushima in 2011 focussed the attention of the world on the vulnerability of ecosystems to radiation. In Chornobyl, there still remains an exclusion zone where levels are considered to be too high for people and impacts on terrestrial and aquatic ecosystems can still be measured 35 years later. In the area impacted by the Fukushima disaster, intense remediation is still under way at tremendous cost and causing widespread disruption to the environment. That accident impacted the terrestrial and marine ecosystems. In both accidents it became obvious that a radiation protection framework focussing on protection of “humans” (a single species) and using evacuation as a key strategy, was not sufficient to protect the natural environment. The complexity of ecosystems makes developing a protection framework very challenging but in order to even start the process it is vital to gather information about likely impacts of low dose exposures on wildlife and to develop monitoring tools to measure changes over time. This book contains reviews and original research aimed at filling our knowledge gaps about these important areas. Environmental Radiobiology will be a key resource for academics, researchers, and advanced students of Radiobiology, Radioecology, Biology, Ecology, Biomedicine and Research Methods. The chapters included in this book were originally published as a special issue of International Journal of Radiation Biology.

Explores equilibrium and non-equilibrium in undisturbed and disturbed ecological systems, examining how human activities affect the balance/imbalance of nature.

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided. A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them
