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... more...

The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play a very significant role in the saline areas specially in the coast by... more...

This completely revised edition includes up-to-date information on distribution, new species and biology of the 59 species of fish found in Alberta. Information on identification, distribution, biology, taxonomic history, and, where appropriate, angling is included. Fishes of Alberta will be useful to anyone interested in Alberta's fishes, from anglers to scientists, as well as students of biology.

This volume provides an identification key for the ephyrae of 18 common scyphozoan species, documents the Mediterranean-wide bloom of the invasive ctenophore Mnemiopsis leidyi, and addresses the direct effects of ocean acidification on jellyfish.

Ohio’s original heavily forested landscape included glacial lakes, large rivers, and streams that teemed with an abundant variety of fish, most of which remain resident today. Native Fishes of Ohio documents the more than 130 species originally found in the state and describes how their aquatic habitats have evolved as a result of agriculture and industrial development. Naturalist Dan Rice and photographer Gary Meszaros draw upon more than 40... more...


Hydrology and Global Environmental Change presents the hydrological contribution to, and consequences of, global environmental change. Assuming little or no prior knowledge on the part of the reader, the book looks at the main processes of global environmental change - global scale processes, large regional processes, repetitive processes - and how the hydrological cycle, processes and regimes impact on GEC and vice-versa.

This book celebrates the fiftieth anniversary of publication of one of the landmarks of the modern ecological thought: the “Homage to Santa Rosalia or why are there so many kinds of animals” by George Evelyn Hutchinson. Published in 1959 in the journal “The American Naturalist”, this article has been the engine which have moved most of the ecological research on biodiversity in the last half a century. Hutchinson starts his article by telling... more...

In Glen Canyon waters rose, inundating petroglyphs and creating Lake Powell. Now the Colorado River basin is experiencing the longest dry spell in modern history—one that shows alarming signs of becoming the new normal.   In A New Form of Beauty photographer Peter Goin and writer Peter Friederici tackle science from the viewpoint of art, creating a lyrical exploration in words and photographs, setting Glen Canyon and Lake... more...

The oceans cover 70% of the terrestrial surface, and exert a pervasive influence on the Earth's environment but their nature is poorly recognized. Knowing the ocean's role deeply and understanding the complex, physical, biological, chemical and geological systems operating within it represent a major challenge to scientists today. Seafloor observatories offer scientists new opportunites to study multiple, interrelated natural phenomena... more...
