Book Description
Fish species that migrate within the great rivers of South America support important local fisheries but are little known outside their native range. This book represents the first collection of the work of local scientific experts on these remarkable fish. The authors cover the Upper Parani, Paraguay-Parani, Uruguay and Suo Francisco basins in Brazil, as well as the Brazilian and Colombian Amazon. They discuss not only the principal migratory species and their fascinating relationship with the water cycle in the rivers and wetlands, but also the fisheries they support, and their often precarious conservation status."

Book Description
This book highlights the advances in essential oil research, from the plant physiology perspective to large-scale production, including bioanalytical methods and industrial applications. The book is divided into 4 sections. The first one is focused on essential oil composition and why plants produce these compounds that have been used by humans since ancient times. Part 2 presents an update on the use of essential oils in various areas, including food and pharma industries as well as agriculture. In part 3 readers will find new trends in bioanalytical methods. Lastly, part 4 presents a number of approaches to increase essential oil production, such as in vitro and hairy root culture, metabolic engineering and biotechnology. Altogether, this volume offers a comprehensive look at what researchers have been doing over the last years to better understand these compounds and how to explore them for the benefit of the society.

Book Description
Ticks of the family Ixodidae, commonly known as hard ticks, occur worldwide and are second only to mosquitoes as vectors of agents pathogenic to humans. Of the 729 currently recognized hard tick species, 283 (39%) have been implicated as human parasites, but the literature on these species is both immense and scattered, with the result that health professionals are often unable to determine whether a particular tick specimen, once identified, represents a species that is an actual or potential threat to its human host. In this book, two leading tick specialists provide a list of the species of Ixodidae that have been reported to feed on humans, with emphasis on their geographical distribution, principal hosts, and the tick life history stages associated with human parasitism. Also included is a discussion of 21 ixodid species that, while having been found on humans, are either not known to have actually fed or may have been misidentified. Additionally, 107 tick names that have appeared in papers on tick parasitism of humans, and that might easily confuse non-taxonomists, are shown to be invalid under the rules of zoological nomenclature. Although the species of ticks that attack humans have long attracted the attention of researchers, few comprehensive studies of these species have been attempted. By gleaning and analyzing the results of over 1,100 scientific papers published worldwide, the authors have provided an invaluable survey of hard tick parasitism that is unprecedented in its scope and detail.

Book Description
In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

Book Description
From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.

Book Description
Based on a workshop held at the University of Bielefeld in Germany in March 1986, this book presents the work of researchers from a diversity of fields, from neuroanatomy to behavioural ecology, covering the anatomy, physiology and behavioural correlates of the auditory system in the vertebrate class amphibia. It summarizes all aspects of the amphibian auditory system, reviewing current knowledge of the structure, function and evolution of this sensory system, and offers new contributions to our understanding of this subject. Chapters discuss amphibian phylogeny, the anatomy and physiology of the peripheral auditory system, the anatomy and physiology of central auditory areas, specialized topics in sound localization, the development of the amphibian auditory system (including changes that occur during metamorphosis), acoustic communication in anurans, selected topics in the evolution of amphibian and vertebrate audition, and others aspects.
