Book Description
This publication provides an historical review and evaluation of documented ecological effects associated with salmonine introductions to the Laurentian Great Lakes. The introduction of salmonines to the Great Lakes date back to the 1870s, when natural populations of native salmonines in the Great Lakes were in severe decline. Using established evaluation protocols, it was determined that there is evidence of significant ecological effects in six different categories: (1) diseases and parasites, (2) predation on native species, (3) competition for limiting resources, (4) genetic alteration, (5) environmental alteration and (6) community alteration. Taken together, this body of evidence supports the conclusion that the ongoing introduction of non-native salmonines poses an ecologically-significant risk to the Great Lakes ecosystem and its native organisms, and that the introductions should be terminated.

New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review 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.

Book Description
The St. Lawrence Seaway was considered one of the world's greatest engineering achievements when it opened in 1959. The $1 billion project-a series of locks, canals, and dams that tamed the ferocious St. Lawrence River-opened the Great Lakes to the global shipping industry. Linking ports on lakes Superior, Michigan, Huron, Erie, and Ontario to shipping hubs on the world's seven seas increased global trade in the Great Lakes region. But it came at an extraordinarily high price. Foreign species that immigrated into the lakes in ocean freighters' ballast water tanks unleashed a biological shift that reconfigured the world's largest freshwater ecosystems. Pandora's Locks is the story of politicians and engineers who, driven by hubris and handicapped by ignorance, demanded that the Seaway be built at any cost. It is the tragic tale of government agencies that could have prevented ocean freighters from laying waste to the Great Lakes ecosystems, but failed to act until it was too late. Blending science with compelling personal accounts, this book is the first comprehensive account of how inviting transoceanic freighters into North America's freshwater seas transformed these wondrous lakes.

Book Description
The ecological sciences are a diverse array of major scientific disciplines. They grew from minor sciences, with little status in 1900, and now occupy crucial areas of research bearing on the future of our planet. This book describes a century of growth and development. A dramatic century-long rise in the status of ecological knowledge was accompanied by the rise of professional ecological organizations, the establishment of university faculties, and the creation of government agencies advising on conservation, natural resources, and the prevention of pollution. Like all sciences, ecology continues to yield new findings and surprising revelations. New technologies now address existential challenges facing our world. This book, documenting the rise of ecology, is an inspiring history portending an important role in the twenty-first century. Key Features: The author is the acknowledged authority on the history of ecology The content is familiar to members of the Ecological Society of America but has not previously been assembled into a single narrative Appropriate for a course in the history of ecology Provides a broad perspective on ecology Related Titles: Egerton, F. N. A Centennial History of the Ecological Society of America (ISBN 978-0-3673-7763-2). Rieppel, O. Phylogenetic Systematics: Haeckel to Hennig (ISBN 978-0-3678-7645-6) Dronamraju, K.

Book Description
The context in which environmental policy decision-making occurs has changed, resulting from widening environmental problems, increased demands from groups and citizens, continuing pressure on the continent's resources and normative shifts. The complexity of current issues is related to an even broader contextual shift: the globalization of environmental issues exacerbated by trade liberalization, especially on a regional level and the potential contradictions between trade and the environmental international agenda that this implies. This volume studies the new dimensions of resource conflict between Canada and the United States, accounting for the emergence of new bilateral environmental issues and detailing how trade liberalization has fostered both disputes and policy convergence. It also examines the recent shifts in America towards a unilateral foreign policy and how this affects active Canadian diplomacy Ideal as a resource tool for students and academics, this book will be a key resource in the areas of global governance, US-Canadian foreign policy and environmental policy.

Book Description
Since 9/11, policy-makers and observers have questioned whether America should don the mantle of empire for the sake of world peace, or whether peace will come through world government. Locating Global Order questions the very idea that the political order is hierarchical, with state and international institutions at the top and groups and individuals at the bottom. Chapters examining various case studies on Canada's role in the construction and maintenance of order domestically and internationally reveal that the global order post-9/11 is not exclusively American � allied powers are a key component of its hegemony.
