Download or read book The Mollusks written by Charles F. Sturm and published by Universal-Publishers. This book was released on 2006 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.

Download or read book Animal Biomarkers as Pollution Indicators written by David B. Peakall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.

Download or read book The Case of the White Footprints written by R. Austin Freeman and published by Simon and Schuster. This book was released on 2014-05-30 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Case of the White Footprints is a murder mystery set in Margate. A lady has been found dead in her room in a boarding house. At first glance it looks like a clear case of suicide, but then the two doctors attending the death spot a set of white footprints in paint on the red linoleum of the floor. As the house is currently being repainted, and the window-sills were still covered in wet paint, it is clear that the woman has been murdered by someone who entered and left through the window. Moreover, the footprints have some strange peculiarities. They are bare footprints...and on both feet it appears that the little toe is missing. When Dr. Thorndyke is called onto the case these extraordinary footprints lead him immediately to the track of the murderer.

Download or read book Coastal Landscapes of South Australia written by Robert P. Bourman and published by University of Adelaide Press. This book was released on 2016-08-09 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geologically, the South Australian coast is very young, having evolved over only 1% of geological time, during the past 43 million years since the separation of Australia and Antarctica. It is also very dynamic, with the current shoreline position having been established from only 7000 years ago. The South Australian mainland coast is 3816 km long, with islands providing an additional 1251 km of coast, giving a total coastline of just over 5000 km. South Australian coastal landforms include cliffs, rocky outcrops and shore platforms, mangrove woodlands, mudflats, estuaries, extensive sandy beaches, coastal dunes and coastal barrier systems, as well as numerous near-shore reefs and islands. This book is a landmark study into the variable character of the South Australian coast and its long-term evolution.
Download or read book The Geography of Georgia written by Igor V. Bondyrev and published by Springer. This book was released on 2015-05-18 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the political and economic history and geography of Georgia, the problems it has faced, and how it has overcome and is still overcoming them. In most countries, at the end of the 20th century the successful resolution of social-economic, political, demographic and ecological problems was largely dependent on effectively protecting the population and economic assets from natural disasters and on ensuring conditions for their sustainable development. These problems are most acute in mountainous regions like Georgia, where the unplanned development of natural ecosystems has had drastic consequences. It is therefore necessary to understand not only the probability of changing conditions (natural as well as political and demographic), but also the probability of the resulting economic losses. The book is divided into four sections; historical and political geography, geological processes, ecological processes and developmental geography. In the historical and political geography section the authors present a detailed discussion on ancient history, historical and political geography, ethnic groups and religions, demographics and socio-cultural geography. The geological processes section contains information on geology, geodynamical processes, glacial and periglacial processes. The ecological processes section examines a variety of landscapes and ecosystems, aspects of deforestation, reforestation and desertification along with anthropogenic impacts on the environment. The developmental geography section looks at different economies, natural resources, sustainable development and climate change.

Download or read book Stream Ecology written by J. David Allan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Download or read book Dinosaurs and Other Extinct Saurians written by Richard Moody and published by Geological Society of London. This book was released on 2010 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of dinosaurs and other large extinct saurians - a term under which the Victorians commonly lumped ichthyosaurs, plesiosaurs, pterosaurs and their kin - makes exciting reading and has caught the attention of palaeontologists, historians of science and the general public alike. The papers in this collection go beyond the familiar tales about famous fossil hunters and focus on relatively little-known episodes in the discovery and interpretation (from both a scientific and an artistic point of view) of dinosaurs and other inhabitants of the Mesozoic world. They cover a long time span, from the beginnings of modern scientific palaeontology in the 1700s to the present, and deal with many parts of the world, from the Yorkshire coast to Central India, from Bavaria to the Sahara. The characters in these stories include professional palaeontologists and geologists (some of them well-known, others quite obscure), explorers, amateur fossil collectors, and artists, linked together by their interest in Mesozoic creatures.
