"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 extremeor adverse environments and climate changes on tadpoles' responses to environmental pollutants"--
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.

Eduardo Alves de Almeida is a biologist with Ph.D. in Biochemistry, and is a full professor at the Regional University of Blumenau, Brazil. He has extensive experience in ecotoxicology, working since 1996 on the effects of environmental pollutants on aquatic vertebrates and invertebrates. He currently coordinates the Center for Studies in Aquatic Toxicology, at the Regional University of Blumenau, where he conducts studies on the effects of pesticides and pharmaceutical compounds on amphibian tadpoles.
Juliane Silberschmidt Freitas is a biologist with a Ph.D. in Animal Biology from the State University of Sćo Paulo, Brazil. Her Ph.D. internship was held at the University of California (UCR) and postdoctoral in Ecotoxicology at the University of Sćo Paulo (USP). Research on amphibians began in 2008 and since 2013 she has been dedicated to understanding the impacts of contaminants on tadpoles. Currently, she teaches Animal Physiology at the University of Minas Gerais (UEMG).
