Boreal Shield Watersheds: Lake Trout Ecosystems in a Changing Environment brings together the work of a renowned international group of scientists who specialize in aquatic science and environmental management. They explore the functioning of Boreal Shield ecosystems, focusing on the lake trout, the classic coldwater species of northern glaciated lakes, using it as an indicator of environmental change and as a model to measure the effectiveness of management actions.
This book demonstrates how boreal waters have served as a crucible for decades of environmental research into the impacts of nutrient additions, trace contaminants, acid rain, climate change, sport fishing, invasive species, and watershed disturbances.
The text builds on this substantial research legacy and explores our ability to manage human interactions with ecosystems across the vast Boreal Shield ecozone of North America, and with other important ecosystems worldwide. It also provides models and new methods of assessing the risk to and the durability of ecosystems in relation to local, regional, and global human activities. Maps and descriptions of several important long-term monitoring sites and an atlas describing more than 3,000 lake trout lakes in the region are special components of the book.
"Relatively little attention has been given to the world's vast boreal wildernesses, yet they are among the most vulnerable to global and other human disturbance. This remarkable and authoritative book is a welcome exception."
- Edward O. Wilson, Professor Emeritus, Harvard University
"This remarkable Precambrian lake region of central Canada has served as a fulcrum for a significant part of modern limnological understanding."
--Robert G. Wetzel, Kenan Professor of Environmental Science, University of North Carolina
"The lake trout is an ideal icon to encourage the wise management of Shield waters."
