The U.S. Geological Survey (USGS) has adapted to the changing political, economic, and technical state of the nation and the world since it was established in the late nineteenth century. Over a period of more than 120 years, the USGS has evolved from a small group of scientists who collected data and provided guidance on how to parcel, manage, and use the public lands of the West to an agency comprised of thousands of scientists who conduct research and assessment activities on complex scientific issues at scales ranging from the local to the global. The USGS will no doubt continue to evolve and adapt to meet changing national needs. In fact, the recent integration of the National Biological Service and parts of the U.S. Bureau of Mines into the USGS presents an ideal opportunity to examine the agency's vision, mission, role, and scientific opportunities as the organization begins the early years of the twenty-first century. The USGS recognized the need to adapt to changing demands when it asked the National Research Council (NRC) to undertake this study. The NRC formed a multidisciplinary committee of 16 experts to address issues related to the future roles, challenges, and opportunities of the agency.
Now a feature-length documentary on the Discovery channel narrated by Tom Brokaw. “Lush, gorgeously written…A profoundly hopeful book.” —Tina Rosenberg, winner of the Pulitzer Prize and the National Book Award A Kirkus Best Book of 2016 Many of the men and women doing today’s most consequential environmental work—restoring America’s grasslands, wildlife, soil, rivers, wetlands, and oceans—would not call themselves environmentalists; they would be too uneasy with the connotations of that word. What drives them is their deep love of the land: the iconic terrain where explorers and cowboys, pioneers and riverboat captains forged the American identity. They feel a moral responsibility to preserve this heritage and natural wealth, to ensure that their families and communities will continue to thrive. Unfolding as a journey down the Mississippi River, Rancher, Farmer, Fisherman tells the stories of five representatives of this stewardship movement: a Montana rancher, a Kansas farmer, a Mississippi riverman, a Louisiana shrimper, and a Gulf fisherman. In exploring their work and family histories and the essential geographies they protect, Rancher, Farmer, Fisherman challenges pervasive and powerful myths about American and environmental values.
The human love of novelty and desire to make one place look like another, coupled with massive increases in global trade and transport, are creating a growing economic and ecological threat. The same forces that are rapidly "McDonaldizing" the world's diverse cultures are also driving us toward an era of monotonous, weedy, and uniformly impoverished landscapes. Unique plant and animal communities are slowly succumbing to the world's "rats and rubbervines" -- animals like zebra mussels and feral pigs, and plants like kudzu and water hyacinth -- that, once moved into new territory, can disrupt human enterprise and well-being as well as native habitats and biodiversity. From songbird-eating snakes in Guam to cheatgrass in the Great Plains, "invasives" are wreaking havoc around the world. In A Plague of Rats and Rubbervines, widely published science writer Yvonne Baskin draws on extensive research to provide an engaging and authoritative overview of the problem of harmful invasive alien species. She takes the reader on a worldwide tour of grasslands, gardens, waterways, and forests, describing the troubles caused by exotic organisms that run amok in new settings and examining how commerce and travel on an increasingly connected planet are exacerbating this oldest of human-created problems. She offers examples of potential solutions and profiles dedicated individuals worldwide who are working tirelessly to protect the places and creatures they love. While our attention is quick to focus on purposeful attempts to disrupt our lives and economies by releasing harmful biological agents, we often ignore equally serious but much more insidious threats, those that we inadvertently cause by our own seemingly harmless actions. A Plague of Rats and Rubbervines takes a compelling look at this underappreciated problem and sets forth positive suggestions for what we as consumers, gardeners, travelers, nurserymen, fishermen, pet owners, business people -- indeed all of us who by our very local choices drive global commerce -- can do to help.

This book provides an important collection of new research that sheds light on many aspects of the evolutionary patterns of gymnosperms, angiosperms, and pteridophtes. The book includes a complete chloroplast genome sequence study and describes a method that induces the systemic silencing of target genes in the Ceratopteris gametophyte. It presents a study of how herbicide treatments reduce fern densities and create the establishment of regeneration. It also analyzes an EST dataset from G. biloba that reveals genes potentially unique to gymnosperms and includes a study of episodic rate acceleration in the ancestral grasses.
In 1953, birding guru Roger Tory Peterson and noted British naturalist James Fisher set out on what became a legendary journey-a one hundred day trek over 30,000 miles around North America. They traveled from Newfoundland to Florida, deep into the heart of Mexico, through the Southwest, the Pacific Northwest, and into Alaska's Pribilof Islands. Two years later, Wild America, their classic account of the trip, was published. On the eve of that book's fiftieth anniversary, naturalist Scott Weidensaul retraces Peterson and Fisher's steps to tell the story of wild America today. How has the continent's natural landscape changed over the past fifty years? How have the wildlife, the rivers, and the rugged, untouched terrain fared? The journey takes Weidensaul to the coastal communities of Newfoundland, where he examines the devastating impact of the Atlantic cod fishery's collapse on the ecosystem; to Florida, where he charts the virtual extinction of the great wading bird colonies that Peterson and Fisher once documented; to the Mexican tropics of Xilitla, which have become a growing center of ecotourism since Fisher and Peterson's exposition. And perhaps most surprising of all, Weidensaul finds that much of what Peterson and Fisher discovered remains untouched by the industrial developments of the last fifty years. Poised to become a classic in its own right, Return to Wild America is a sweeping survey of the natural soul of North America today.
