The Great Lakes: The Natural History of a Changing Region

Angebote / Angebote:

Five immense lakes lie at the heart of North America. They cover an area of nearly 95, 000 square miles and hold more than 5, 500 cubic miles of water. Together they comprise the world's largest freshwater system, containing 95 percent of the continent's fresh water - and one-fifth of the planet's total supply. Home to 40 million people, the Great Lakes' drainage basin is the hub of industry and agriculture in North America. More than a region, it is almost a nation in itself. The Great Lakes: A Natural History of a Changing Region is the most authoritative, complete and accessible book to date about the biology and ecology of this vital, ever-changing terrain. It begins with an account of the geological formation of the lakes and an overview of the lakes' role in relatively recent human history. Grady takes readers through the lakes basin, defined and explored by its three component forest ecosystems: the Boreal, the Great Lakes/St Lawrence and the Carolinian Forests. Representative flora and fauna species are profiled, along with notable physical, climatic, and environmental features. The Great Lakes is both a first-hand tribute and an essential guide to a fascinating ecosystem in eternal flux.
