The Branches of Ecology
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 cha...
Extinction in Our Times
For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.
Peril in the Ponds
When deformed frogs-many with missing legs or eyes, footless stumps, or misshapen jaws-began to emerge from Minnesota wetlands, alarm bells went off. What caused such deformities? Pollution? Ultraviolet rays? Biological agents? And could the mysterious cause also pose a threat to humans? Former government biologist Judy Helgen provides an inside view of a highly charged environmental issue that continues to spark controversy among scientists, politicians, and government agencies.

Wildflowers and Other Plants of Iowa Wetlands, 2nd Edition
Originally published in 1999, Wildflowers and Other Plants of Iowa Wetlands was the first book to focus on the beauty and diversity of the wetland plants that once covered 1.5 million acres of Iowa. Now this classic of midwestern natural history is back in print with a new format and all-new photographs, just as Iowa’s wetlands are getting the respect and attention they deserve. In clear and accessible prose, authors Sylvan Runkel and Dean Roosa provide common, scientific, and family names; the Latin or Greek meaning of the scientific names; habitat and blooming times; and a complete description. Plants are presented by habitat (terrestrial or aquatic), then refined by habit (e.g., emergen...
From the Corn Belt to the Gulf
Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the pot...
The Media Creates Us in Its Image and Other Essays on Technology and Culture
The Media Creates Us in Its Image and Other Essays on Technology and Culture proposes that modern technology seriously influences every aspect of culture and personality. Technology shapes our beliefs and values and even how we think of ourselves. It affects religion, morality, education, language, communication, and sexual identity. Every institution, every organization, is brought under its purview. This book attempts to awaken the reader to the destructive side of modern technology that exists side-by-side with its constructive side. What modern technology is destroying, however, is the very meaning of being human. The essay "The Media Creates Us in Its Image" makes this case most dramatically. The book asks the reader the following question: Is what you have gained from the use of modern technology more important than what you have lost? How do we once again bring technology under our control in the face of its inexorable "progress"?
