Life and Death of the Salt Marsh by John Teal,Mildred Teal Pdf
"At low tide, the wind blowing across Spartina grass sounds like wind of the prairie. When the tide is in, the gentle music of moving water is added to the prairie rustle.... " One of nature's greatest gifts is the string of salt marshes that edges the East Coast from Newfoundland to Florida -- a ribbon of green growth, part solid land, part scurrying water. Life and Death of the Salt Marsh shows how these marshes are developed, what kinds of life inhabit them, how enormously they have contributed to man, and how ruthlessly man is destroying them.
Engaging the Avatar by Charles Wankel,Randy Hinrichs Pdf
This volume has a bold agenda, in which academics create immersive worlds where the avatar is the center of the universe. As the virtual world grows, avatars move away from quasi-human interactions within virtual domiciles, gardens, and businesses to being blood cells in the blood stream, or to be firing neurons in the human brain, or creatures competing on the ocean floor or the surface of Mars or just about anything that can be imagined using the magic of photographic and artistic images, programming, narrative and avatars. What are the frameworks and strategies for building these environments? What are the things the avatar adapts and learns from in its environment? This book will examine such frameworks, strategies, examples and feedback systems to explore what it takes to create a global education environment for learning. This starts with engaging your avatar and is completed in a transformation in how you interact with the internet. Whether using the visual internet to learn or to interact with a customer about a product or service, this immersive interface can be a world that knows you and forms around your unique needs and interests.
The World of The Salt Marsh by Charles Seabrook Pdf
The World of the Salt Marsh is a wide-ranging exploration of the southeastern coast--its natural history, its people and their way of life, and the historic and ongoing threats to its ecological survival. Focusing on areas from Cape Hatteras, North Carolina, to Cape Canaveral, Florida, Charles Seabrook examines the ecological importance of the salt marsh, calling it "a biological factory without equal." Twice-daily tides carry in a supply of nutrients that nourish vast meadows of spartina ( Spartina alterniflora )--a crucial habitat for creatures ranging from tiny marine invertebrates to wading birds. The meadows provide vital nurseries for 80 percent of the seafood species, including oysters, crabs, shrimp, and a variety of finfish, and they are invaluable for storm protection, erosion prevention, and pollution filtration. Seabrook is also concerned with the plight of the people who make their living from the coast's bounty and who carry on its unique culture. Among them are Charlie Phillips, a fishmonger whose livelihood is threatened by development in McIntosh County, Georgia, and Vera Manigault of Mount Pleasant, South Carolina, a basket maker of Gullah-Geechee descent, who says that the sweetgrass needed to make her culturally significant wares is becoming scarcer. For all of the biodiversity and cultural history of the salt marshes, many still view them as vast wastelands to be drained, diked, or "improved" for development into highways and subdivisions. If people can better understand and appreciate these ecosystems, Seabrook contends, they are more likely to join the growing chorus of scientists, conservationists, fishermen, and coastal visitors and residents calling for protection of these truly amazing places.
Tall green grass. Subtle melodies of songbirds. Sharp whines of muskrats. Rustles of water running through the grasses. And at low tide, a pungent reminder of the treasures hidden beneath the surface.All are vital signs of the great salt marshes' natural resources. Now championed as critical habitats for plants, animals, and people because of the environmental service and protection they provide, these ecological wonders were once considered unproductive wastelands, home solely to mosquitoes and toxic waste, and mistreated for centuries by the human population. Exploring the fascinating biodiversity of these boggy wetlands, Salt Marshes offers readers a wealth of essential information about a variety of plants, fish, and animals, the importance of these habitats, consequences of human neglect and thoughtless development, and insight into how these wetlands recover. Judith S. Weis and Carol A. Butler shed ample light on the human impact, including chapters on physical and biological alterations, pollution, and remediation and recovery programs. In addition to a national and global perspective, the authors place special emphasis on coastal wetlands in the Atlantic and Gulf regions, as well as the San Francisco Bay Area, calling attention to their historical and economic legacies. Written in clear, easy-to-read language, Salt Marshes proves that the battles for preservation and conservation must continue, because threats to salt marshes ebb and flow like the water that runs through them.
U.S. Environmental Protection Agency Library System Book Catalog Holdings as of July 1973 by United States. Environmental Protection Agency. Library Systems Branch Pdf
Concrete floors and concrete walls, buildings that pierce the sky, taxicabs and subway corridors, a steady din of noise. These things, along with a virtually unrivaled collection of museums, galleries, performance venues, media outlets, international corporations, and stock exchanges make New York City not only the cultural and financial capital of the United States, but one of the largest and most impressive urban conglomerations in the world. With distinctions like these, is it possible to imagine the city as any more than this? City at the Water's Edge invites readers to do just that. Betsy McCully, a long-time urban dweller, argues that this city of lights is much more than a human-made metropolis. It has a rich natural history that is every bit as fascinating as the glitzy veneer that has been built atop it. Through twenty years of nature exploration, McCully has come to know New York as part of the Lower Hudson Bioregion-a place of salt marshes and estuaries, sand dunes and barrier islands, glacially sculpted ridges and kettle holes, rivers and streams, woodlands and outwash plains. Here she tells the story of New York that began before the first humans settled in the region twelve thousand years ago, and long before immigrants ever arrived at Ellis Island. The timeline that she recounts is one that extends backward half a billion years; it plumbs the depths of Manhattan's geological history and forecasts a possible future of global warming, with rising seas lapping at the base of the Empire State Building. Counter to popular views that see the city as a marvel of human ingenuity diametrically opposed to nature, this unique account shows how the region has served as an evolving habitat for a diversity of species, including our own. The author chronicles the growth of the city at the expense of the environment, but leaves the reader with a vision of a future city as a human habitat that is brought into balance with nature.
Ecology of North America by Brian R. Chapman,Eric G. Bolen Pdf
North America contains an incredibly diverse array of natural environments, each supporting unique systems of plant and animal life. These systems, the largest of which are biomes, form intricate webs of life that have taken millennia to evolve. This richly illustrated book introduces readers to this extraordinary array of natural communities and their subtle biological and geological interactions. Completely revised and updated throughout, the second edition of this successful text takes a qualitative, intuitive approach to the subject, beginning with an overview of essential ecological terms and concepts, such as competitive exclusion, taxa, niches, and succession. It then goes on to describe the major biomes and communities that characterize the rich biota of the continent, starting with the Tundra and continuing with Boreal Forest, Deciduous Forest, Grasslands, Deserts, Montane Forests, and Temperature Rain Forest, among others. Coastal environments, including the Laguna Madre, seagrasses, Chesapeake Bay, and barrier islands appear in a new chapter. Additionally, the book covers many unique features such as pitcher plant bogs, muskeg, the polar ice cap, the cloud forests of Mexico, and the LaBrea tar pits. “Infoboxes” have been added; these include biographies of historical figures who provided significant contributions to the development of ecology, unique circumstances such as frogs and insects that survive freezing, and conservation issues such as those concerning puffins and island foxes. Throughout the text, ecological concepts are worked into the text; these include biogeography, competitive exclusion, succession, soil formation, and the mechanics of natural selection. Ecology of North America 2e is an ideal first text for students interested in natural resources, environmental science, and biology, and it is a useful and attractive addition to the library of anyone interested in understanding and protecting the natural environment.

Sapelo, a state-protected barrier island off the Georgia coast, is one of the state’s greatest treasures. Presently owned almost exclusively by the state and managed by the Georgia Department of Natural Resources, Sapelo features unique nature characteristics that have made it a locus for scientific research and ecological conservation. Beginning in 1949, when then Sapelo owner R. J. Reynolds Jr. founded the Sapelo Island Research Foundation and funded the research of biologist Eugene Odum, UGA’s study of the island’s fragile wetlands helped foster the modern ecology movement. With this book, Buddy Sullivan covers the full range of the island’s history, including Native American inhabitants; Spanish missions; the antebellum plantation of the innovative Thomas Spalding; the African American settlement of the island after the Civil War; Sapelo’s two twentieth-century millionaire owners, Howard E. Coffin and R. J. Reynolds Jr., and the development of the University of Georgia Marine Institute; the state of Georgia acquisition; and the transition of Sapelo’s multiple African American communities into one. Sapelo Island’s history also offers insights into the unique cultural circumstances of the residents of the community of Hog Hammock. Sullivan provides in-depth examination of the important correlation between Sapelo’s culturally significant Geechee communities and the succession of private and state owners of the island. The book’s thematic approach is one of “people and place”: how prevailing environmental conditions influenced the way white and black owners used the land over generations, from agriculture in the past to island management in the present. Enhanced by a large selection of contemporary color photographs of the island as well as a selection of archival images and maps, Sapelo documents a unique island history.
The paths of different birds look like double helixes, flowing strands of hair, and migrating serpents, and they beckon with calls that have definite meanings. These mysterious creatures inspire growing numbers of birders in their passionate pursuit of new species, and writer John R. Nelson is no exception. In Flight Calls, he takes readers on explorations to watch, hear, and know Massachusetts's hummingbirds, hawks, and herons along the coasts and in the woodlands, meadows, and marshes of Cape Ann, Cape Cod, the Great Marsh, Mount Auburn Cemetery, the Quabbin wilderness, Mount Wachusett, and elsewhere. With style, humor, and a sense of wonder, Nelson blends his field adventures with a history of the birding community; natural and cultural history; bird stories from authors such as Henry David Thoreau, Emily Dickinson, and Mary Oliver; current scientific research; and observations about the fascinating habits of birds and their admirers. These essays are capped off with a plea for bird conservation, in Massachusetts and beyond.
