Book Description
Salt marshes are highly dynamic and important ecosystems that dampen impacts of coastal storms and are an integral part of tidal wetland systems, which sequester half of all global marine carbon. They are now being threatened due to sea-level rise, decreased sediment influx, and human encroachment. This book provides a comprehensive review of the latest salt marsh science, investigating their functions and how they are responding to stresses through formation of salt pannes and pools, headward erosion of tidal creeks, marsh-edge erosion, ice-fracturing, and ice-rafted sedimentation. Written by experts in marsh ecology, coastal geomorphology, wetland biology, estuarine hydrodynamics, and coastal sedimentation, it provides a multidisciplinary summary of recent advancements in our knowledge of salt marshes. The future of wetlands and potential deterioration of salt marshes is also considered, providing a go-to reference for graduate students and researchers studying these coastal systems, as well as marsh managers and restoration scientists.

Book Description
Introduces young readers to hourly changes in the salt marsh as the tide comes and goes, following the animals that have adapted to this ever-changing environment as they hunt for food or play in the sun.

Book Description
When Mildred and John Teal moved to Sapelo Island, Georgia, in 1955, they stepped back in time to a virtually undeveloped landscape of salt marsh, maritime forest, freshwater ponds, sand dunes, and beaches. Over the course of a four-year stay their careful observations of the island's unique marine ecology and wonderfully varied flora and fauna became the basis for Portrait of an Island. The island's human history dates back more than four thousand years. The lure of Sapelo has drawn many to its shores, including tobacco millionaire R. J. Reynolds, who established the University of Georgia Marine Institute there in the 1950s. Surrounded by sixteen thousand acres of pristine marsh, Sapelo offers researchers and the public a rare opportunity for environmental studies. Now a state game refuge and national estuarine sanctuary, the island remains a special haven where humans and nature quietly and peacefully coexist. Portrait of an Island is essential reading for anyone who treasures tranquility.

Book Description
Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to `natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the `great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of `outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The `revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be `mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer to understanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.

Book Description
Smeagull the Seagull comes to the house near the shore every day and knocks on the sliding glass door. He knocks when he¿s hungry, and the people who live there feed him. Smeagull rules the roost! Keeping him fed is an exhausting job, but when Smeagull disappears, it makes clear what an important family member Smeagull has become. There are few places on earth without seagulls, both on shore and inland, and every child will find Smeagull captivating and yet familiar. Smeagull the Seagull teaches young children that animals are precious and have needs and feelings and family, just like us.This is a true story. Smeagull is a wild herring gull who does indeed knock at Valerie and Mark¿s house every day where he is fed scraps from sustainable seafood.The book is illustrated in full color by the graphic designer, Valerie Elaine Pettis. The text is written in rhyme by Mark Seth Lender, a published author and producer for wildlife content at Living on Earth, which is nationally broadcast on Public Radio.

Book Description
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.
