Book Description
Thomson presents a detailed history of the natural events that shaped the terrain of the Middle West and an interpretation of the dynamic forces which continue to change its landscapes. Drawing on the sciences of ecology, botany and geology, she describes a land of magnificent fertility and mineral wealth and traces man's influence on the land back to the Indians and the lives and efforts of the early settlers and farmers.

Book Description
How people perceive wetlands has always played a crucial role in determining how people act toward them. In this readable and objective account, Hugh Prince examines literary evidence as well as government and scientific documents to uncover the history of changing attitudes toward wetlands in the American Midwest. As attitudes changed, so did scientific research agendas, government policies, and farmers' strategies for managing their land. Originally viewed as bountiful sources of wildlife by indigenous peoples, wet areas called "wet prairies," "swamps," or "bogs" in the late nineteenth and early twentieth centuries were considered productive only when drained for agricultural use. Beginning in the 1950s, many came to see these renamed "wetlands" as valuable for wildlife and soil conservation. Prince's book will appeal to a wide readership, ranging from geographers and environmental historians to the many government and private agencies and individuals concerned with wetland research, management, and preservation.

Book Description
The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.
