A landmark work of science, history and reporting on the past, present and imperiled future of the Great Lakes. The Great Lakes—Erie, Huron, Michigan, Ontario and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come. For thousands of years the pristine Great Lakes were separated from the Atlantic Ocean by the roaring Niagara Falls and from the Mississippi River basin by a “sub-continental divide.” Beginning in the late 1800s, these barriers were circumvented to attract oceangoing freighters from the Atlantic and to allow Chicago’s sewage to float out to the Mississippi. These were engineering marvels in their time—and the changes in Chicago arrested a deadly cycle of waterborne illnesses—but they have had horrendous unforeseen consequences. Egan provides a chilling account of how sea lamprey, zebra and quagga mussels and other invaders have made their way into the lakes, decimating native species and largely destroying the age-old ecosystem. And because the lakes are no longer isolated, the invaders now threaten water intake pipes, hydroelectric dams and other infrastructure across the country. Egan also explores why outbreaks of toxic algae stemming from the overapplication of farm fertilizer have left massive biological “dead zones” that threaten the supply of fresh water. He examines fluctuations in the levels of the lakes caused by manmade climate change and overzealous dredging of shipping channels. And he reports on the chronic threats to siphon off Great Lakes water to slake drier regions of America or to be sold abroad. In an age when dire problems like the Flint water crisis or the California drought bring ever more attention to the indispensability of safe, clean, easily available water, The Death and the Life of the Great Lakes is a powerful paean to what is arguably our most precious resource, an urgent examination of what threatens it and a convincing call to arms about the relatively simple things we need to do to protect it.

Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

This book places the main actors in environmental microbiology, namely the microorganisms, on center stage. Using the modern approach of 16S ribosomal RNA, the book looks at the taxonomy of marine and freshwater bacteria, fungi, protozoa, algae, viruses, and the smaller aquatic animals such as nematodes and rotifers, as well as at the study of unculturable aquatic microorganisms (metagenomics). The peculiarities of water as an environment for microbial growth, and the influence of aquatic microorganisms on global climate and global recycling of nitrogen and sulphur are also examined. The pollution of water is explored in the context of self-purification of natural waters. Modern municipal water purification and disease transmission through water are discussed. Alternative methods for solid waste disposal are related to the economic capability of a society. Viruses are given special attention. By focusing on the basics, this primer will appeal across a wide range of disciplines.

Shallow wetlands that occur primarily in semi-arid to arid environments, playas are keystone ecosystems in the western Great Plains of North America. Providing irreplaceable habitat for native plants and animals, including migratory birds, they are essential for the maintenance of biotic diversity throughout the region. Playas also serve to recharge the aquifer that supplies much of the water for the Plains states. At the same time, however, large-scale habitat changes have endangered playas across the Great Plains, making urgent the need to understand their ecology and implement effective conservation measures. This book provides a state-of-the-art survey of all that is currently known about Great Plains playa ecology and conservation. Loren Smith synthesizes his own extensive research with other published studies to define playas and characterize their origin, development, flora, fauna, structure, function, and diversity. He also thoroughly explores the human relationship with playas from prehistoric times, when they served as campsites for the Clovis peoples, to today's threats to playa ecosystems from agricultural activities and global climate change. A blueprint for government agencies, private conservation groups, and concerned citizens to save these unique prairie ecosystems concludes this landmark study.
