Download or read book Decaying Lakes written by B. Henderson-Sellers and published by . This book was released on 1987-05-08 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to eutrophication, the process by which the water quality of lakes deteriorates as a result of their increased levels of nutrients. (These nutrients, however, also increase the fertility of lakes.) The process normally takes centuries, but is accelerating as a result of man's activities in catchment areas. The book is divided into three parts. The first part looks at basic causes and control strategies; the second considers conflict between the natural environment and man's influence; the third presents the scientific basis of our understanding of both eutrophication and its control.

Download or read book Crystals of Dead Lakes written by Kim Aaron and published by still is the written word Publishing. This book was released on 2023-08-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last few years have separated people, physically and mentally. This isolation has not been healthy. Human beings are social creatures. Even so, many people were lonely or isolated long before the pandemic. My writing, despite itself, constantly toys with experiences of isolation, be it a physical separation from others, or that sense we get of being alone in a crowd. Loneliness and isolation have been near constant partners in my life, to more or lesser degrees, so the fact I find them showing up in my writing shouldn’t really be a surprise. Noticing thusly as I stare into the mirror, I decided to face isolation and loneliness directly, with a book of short stories orbiting these ideas, examining them from different angles like the facets of a cut diamond. My Crystals of Dead Lakes.

Download or read book Lakes A Very Short Introduction written by Warwick F. Vincent and published by Oxford University Press. This book was released on 2018-01-18 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the mysterious depths of Lake Vostok, Antarctica, to tropical floodplain lakes, inland seas, hydro-reservoirs and the variety of waterbodies in our local environment, lakes encompass a huge diversity of shapes, sizes, depths, colours, and even salinities. Often very large and very deep, they sustain important and unique ecosystems which can be hotspots of biodiversity, and are used by humans as sources of drinking water and food, in particular, fish. What is the origin of differences among lakes, and how does that affect the life within them? What are the seasons of a lake, and how do human actions alter lake ecosystems locally, and at a global scale? In this Very Short Introductions, Warwick Vincent outlines the essential features of lake environments and their biology, offering an up-to-date view of lake ecosystems. Vincent traces the origins of lake science (limnology) from the seminal work of François Forel on Lake Geneva at the edge of the Swiss Alps, to modern approaches such as environmental sensors, satellite observations, stable isotope analysis, and DNA-based technologies which are used to probe the microbial life support systems that lead from sunlight to fish. Drawing on varied case studies he considers the intimate relationship between humans and lakes, the value of lakes as indicators of environmental change, the impact of pollution,and our urgent need to improve the protection and management of these vitally important living resources via an integrated understanding of their ecology. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Download or read book Nutrient Dynamics and Retention in Land Water Ecotones of Lowland Temperate Lakes and Rivers written by A. Hillbricht-Ilkowska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.

Download or read book Still Waters The Secret World of Lakes written by Curt Stager and published by W. W. Norton & Company. This book was released on 2018-05-29 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating exploration of lakes around the world, from Walden Pond to the Dead Sea. More than a century and a half have passed since Walden was first published, and the world is now a very different place. Lakes are changing rapidly, not because we are separate from nature but because we are so much a part of it. While many of our effects on the natural world today are new, from climate change to nuclear fallout, our connections to it are ancient, as core samples from lake beds reveal. In Still Waters, Curt Stager introduces us to the secret worlds hidden beneath the surfaces of our most remarkable lakes, leading us on a journey from the pristine waters of the Adirondack Mountains to the wilds of Siberia, from Thoreau’s cherished pond to the Sea of Galilee. Through decades of firsthand investigations, Stager examines the significance of our impacts on some of the world’s most iconic inland waters. Along the way he discovers the stories these lakes contain about us, including our loftiest philosophical ambitions and our deepest myths. For him, lakes are not only mirrors reflecting our place in the natural world but also windows into our history, culture, and the primal connections we share with all life. Beautifully observed and eloquently written, Stager’s narrative is filled with strange and enchanting details about these submerged worlds—diving insects chirping underwater like crickets, African crater lakes that explode, and the growing threats to some of our most precious bodies of water. Modern science has demonstrated that humanity is an integral part of nature on this planet, so intertwined with it that we have also become an increasingly powerful force of nature in our own right. Still Waters reminds us how beautiful, complex, and vulnerable our lakes are, and how, more than ever, it is essential to protect them.

Download or read book Dead Zones written by David L. Kirchman and published by Oxford University Press, USA. This book was released on 2021-02-02 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dead zones are on the rise... Human activity has caused an increase in uninhabitable, oxygen-poor zones--also known as "dead zones"--in our waters. Oxygen is the third most abundant element in the universe, and it is a necessity for nearly all life on Earth. Yet many rivers, estuaries, coastal waters, and parts of the open ocean lack enough of it. In this book, David L. Kirchman explains the impacts of dead zones and provides an in-depth history of oxygen loss in water. He details the role the agricultural industry plays in water pollution, showcasing how fertilizers contaminate water supplies and kickstart harmful algal blooms in local lakes, reservoirs, and coastal oceans. Algae decomposition requires so much oxygen that levels drop low enough to kill fish, destroy bottom-dwelling biota, reduce biological diversity, and rearrange food webs. We can't undo the damage completely, but we can work together to reduce the size and intensity of dead zones in places like the Gulf of Mexico, Chesapeake Bay, and the Baltic Sea. Not only does Kirchman clearly outline what dead zones mean for humanity, he also supplies ways we can reduce their deadly impact on human and aquatic life. Nutrient pollution in some regions has already begun to decline because of wastewater treatment, buffer zones, cover crops, and precision agriculture. More needs to be done, though, to reduce the harmful impact of existing dead zones and to stop the thousands of new ones from cropping up in our waters. Kirchman provides insight into the ways changing our diet can reduce nutrient pollution while also lowering greenhouse gasses emitted by the agricultural industry. Individuals can do something positive for their health and the world around them. The resulting book allows readers interested in the environment--whether students, policymakers, ecosystem managers, or science buffs--to dive into these deadly zones and discover how they can help mitigate the harmful effects of oxygen-poor waters today.

Download or read book Environment Betrayed written by Edward C. Krug and published by iUniverse. This book was released on 2012-05-30 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this collection of articles, an environmental scientist traces a journey through the wilderness of environmental politics. In his travels, Dr. Edward Krug developed a unique perspective on vital areas of the environmental issues, making him critical of both sides of the environmental debate. "Environment Betrayed" delves into numerous environmental issues and into environmentalism itself, presenting both Dr. Krug's opinions and the well-documented opinions of others who were active participants in the environmental arena. Dr. Krug has worked as an environmental scientist since the early eighties, and much of the research and information included here originated in the eighties and nineties. Despite this gap of time, defenders of modern Western civilization don't seem to recognize the nature of the environmental war, let alone many of its details. By raising issues, environmentalists also define the battlefield-that is, the context of thought. Krug cites credible sources on both sides of the debate with varying perspectives on where things stand in this conflict. Only by gaining a clear understanding of what's at stake can we truly grasp the numerous environmental issues swirling around us and what they will mean for our future.
