The Late, Great Lakes is a powerful indictment of man's carelessness, ignorance, and apathy toward the Great Lakes. With the longest continuous coastline in the United States, they hold one-fifth of the world's freshwater supply. Author William Ashworth presents a compelling history of the Great Lakes, from their formation in the Ice Age, to their "discovery" by Samuel de Champlian in 1615, and, finally, to their impending death in our time. Ashworth systematically deals with the wild life that once flourished in the region-beaver, salmon, whitefish, and trout-and describes the threatening elements which have displaced them-the predatory sea lamprey, the alewives, toxic waste, and volatile solids.

The International Society for Ecological Modelling (ISEM) sponsors conferences, workshops and training courses with the aim of advancing the development of ecological and environmental modelling. The 3rd International Conference on the state-of-the-art in ecological modelling was sponsored by the ISEM in cooperation with the National Park Service Water Resources Laboratory and hosted by the Natural Resource Ecology Laboratory at Colorado State University. Its theme was the application of ecological modelling to environmental management and this book contains the full texts of the three invited papers presented in the five general sessions, plus the final summaries and syntheses of the topics covered during those sessions.
