For a man cut loose from his life in the U.S., Lake Baikal-Siberia's sacred inland sea-becomes a place of pilgrimage, the focal point of a 25,000-mile journey by land and sea in search of connection, permanence, restoration and hope.

Following a difficult divorce, veteran environmental journalist Peter Thomson sets off from Boston with his younger brother for one of nature's most remarkable creations, in one of the farthest...

If fresh water is to be treasured, the Great Lakes are the mother lode. No bodies of water can compare to them. One of them, Superior, is the largest lake on earth, and the five lakes together contain a fifth of the world's supply of standing fresh water. Their ten thousand miles of shoreline bound eight states and a Canadian province and are longer than the entire Atlantic and Pacific coasts of the United States. Their surface area of 95,000 square miles is greater than New York, New Jersey, Connecticut, Massachusetts, Vermont, New Hampshire, and Rhode Island combined. People who have...

Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework.

The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used...

Annelida, mainly consisting of marine Polychaeta and in faunal and partly parasitic Clitellata, is one the most significant metazoan taxa. Its more than 20.000 described species invade nearly all habitats and play a central role in marine benthic systems as well as in terrestrial soil communities. Annelids include all soft-bodied segmented worm-like organisms and have been recognized as a separate "phylum" for almost 200 years.

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as...

This book comes after several decades of outstanding and successful research that has helped ameliorate some of the most important and controversial fisheries issues in the world ??? those associated with the unwanted wastage of fish from by-catch and discarding.

The 8 chapters encompass contributions from 27 of the world??'s leading experts in by-catch reduction. They take the reader through most aspects of the field at a variety of scales and viewpoints. They examine the methodologies used to develop by-catch reduction techniques and provide new avenues for...
