Book Description
"This book provides up-to-date information on the effects of environmental pollutants on larval development of anuran amphibians from spawning to the end of metamorphosis. It focuses on molecular, biochemical and physiological aspects of tadpoles associated with the lifestyle and ecology of the many species of anuran tadpoles found in natural environments. Anurans are among the most endangered animal groups, presenting populations with the highest known decline rates on the planet. Among the main causes of this decline are environmental pollutants, which impose negative effects on animals, impairing their development, growth, reproduction and survival. For a better management, conservation and protection of anuran species, it is important to know how anthropogenic pollutants affect their metabolism and physiology. Data from studies on anuran toxicology may support more effective policies for the conservation of these organisms, mitigating the decline of their populations, and resulting in better environmental legislation and regulation aiming the protection of these endangered organisms. The book also provides information on the use of anuran tadpoles as model organisms in human toxicology, and about the influence of environmental factors such as extreme or adverse environments and climate changes on tadpoles' responses to environmental pollutants"--

Book Description
Anuran amphibians are among the animal groups with the highest rate of population decline on the planet. Among the factors driving this decline are environmental pollutants, whose negative effects on larvae and tadpoles are still relatively little studied. This is the first book devoted entirely to studying the effects of environmental pollutants on amphibian tadpoles. Throughout its 14 chapters, various aspects of the toxic effects of different classes of environmental contaminants are explored, such as the toxicokinetics of toxic compounds in tadpoles and their health effects, which may result in negative consequences at populations level.

Book Description
Although feeding is not yet been thoroughly studied in many vertebrates taxa, and different conceptual and methodological approaches of the concerned scientists make a synthesis difficult, the aim of the editors is to provide a comprehensive overview of the feeding design in aquatic and terrestrial vertebrates with a detailed description of its functional properties. The book emphasizes the constant interaction between function and form, behaviour and morphology in the course of evolution of the feeding apparatus and way of feeding both complementary and basically related to survival interspecific competition, adaptation to environmental changes and adaptive radiations. Special stress is drawn onquantification of the observational and experimental data on the morphology and biomechanics of the feeding design and its element jaws, teeth, hyoidean apparatus, tongue, in order to allow present and further comparisons in an evolutionary perspective.

Book Description
CHEMOMETRICS AND CHEMINFORMATICS IN AQUATIC TOXICOLOGY Explore chemometric and cheminformatic techniques and tools in aquatic toxicology Chemometrics and Cheminformatics in Aquatic Toxicology delivers an exploration of the existing and emerging problems of contamination of the aquatic environment through various metal and organic pollutants, including industrial chemicals, pharmaceuticals, cosmetics, biocides, nanomaterials, pesticides, surfactants, dyes, and more. The book discusses different chemometric and cheminformatic tools for non-experts and their application to the analysis and modeling of toxicity data of chemicals to various aquatic organisms. You’ll learn about a variety of aquatic toxicity databases and chemometric software tools and webservers as well as practical examples of model development, including illustrations. You’ll also find case studies and literature reports to round out your understanding of the subject. Finally, you’ll learn about tools and protocols including machine learning, data mining, and QSAR and ligand-based chemical design methods. Readers will also benefit from the inclusion of: A thorough introduction to chemometric and cheminformatic tools and techniques, including machine learning and data mining An exploration of aquatic toxicity databases, chemometric software tools, and webservers Practical examples and case studies to highlight and illustrate the concepts contained within the book A concise treatment of chemometric and cheminformatic tools and their application to the analysis and modeling of toxicity data Perfect for researchers and students in chemistry and the environmental and pharmaceutical sciences, Chemometrics and Cheminformatics in Aquatic Toxicology will also earn a place in the libraries of professionals in the chemical industry and regulators whose work involves chemometrics.

Book Description
Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Book Description
The potential impact of anthropogenic pollutants such as agrochemicals on the environment is of global concern. Increasing use of certain compounds can result in contamination of food, water and atmospheric systems and in order to combat this pollution it is important to be able to accurately monitor the short and long term effects. This book describes the latest non-traditional terrestrial species models used as indicators of the toxic effects of environmental pollutants. The book enables understanding of the effects of pollutants in non-target species, and therefore enables analysis of the effects on ecosystems. This book will be of interest to anyone interested in developing new biomarker species with high degrees of ecological relevance. It will serve as a useful resource for regulatory and research toxicologists, particularly those interested in soil screening and the effects of pollutants on wildlife and insects and their use as biological indicators.
