Coastal barrier resources system mapping process Coastal barrier resources system mapping process
The Coastal Barrier Resources Act of 1982 (P.L. 97-348) established the Coastal Barrier Resources System (system), a 452,834 acre system of undeveloped, unprotected coastal barriers along 666 shoreline miles of the Atlantic Ocean and Gulf of Mexico coasts. Within the 186 unites of the Coastal Barrier Resources System, most Federal expenditures that encourage development are prohibited...

Foods and dietary strategies of prairie-nesting ruddy ducks and redheads Foods and dietary strategies of prairie-nesting ruddy ducks and redheads
Actively feeding Ruddy Ducks (Oxyura jamaicensis) and Redheads (Aythya americana) were collected from North Dakota wetlands during the 1979-1981 breeding seasons. Foods found within esophagi were analyzed on a wet-weight aggregate percent basis. Male and prelaying and laying female Ruddy Ducks consumed >90% invertebrates, primarily chironomids. Postlaying female Ruddy Ducks consumed 73%

Rising water levels and the future of southeastern Louisiana swamp forests Rising water levels and the future of southeastern Louisiana swamp forests
An important factor contributing to the deterioration of wetland forests in Louisiana is increasing water levels resulting from eustatic sea-level rise and subsidence. Analyses of long-term water level records from the Barataria and Verret watersheds in southeastern Louisiana indicate an apparent sea level rise of about 1-m per century, mainly the result of subsidence. Permanent study...

Accretion and canal impacts in a rapidly subsiding wetland II: Feldspar marker horizon technique Accretion and canal impacts in a rapidly subsiding wetland II: Feldspar marker horizon technique
Recent (6–12 month) marsh sediment accretion and accumulation rates were measured with feldspar marker horizons in the vicinity of natural waterways and man-made canals with spoil banks in the rapidly subsiding environment of coastal Louisiana. Annual accretion rates in aSpartina alterniflora salt marsh in the Mississippi deltaic plain averaged 6 mm in marsh adjacent to canals compared...

Field validation of a habitat suitability index model for the American oyster Field validation of a habitat suitability index model for the American oyster
A habitat suitability index (HSI) model, developed for the American oyster,Crassostrea virginica, along the Gulf of Mexico, was field tested on 38 0.1-ha reef and nonreef sites in Galveston Bay, Texas. The HSI depends upon six (HSI1) or, optionally, eight (HSI2) variables. The six variables are percent of bottom covered with suitable cultch (V1), mean summer water salinity (V2), mean...

Habitat relationships of island nesting seabirds along Coastal Louisiana Habitat relationships of island nesting seabirds along Coastal Louisiana
Seabirds in the saline marsh of coastal Louisiana nest on the islands that are more isolated, smaller, have lower percentages of woody vegetation, and higher percentages of herbaceous vegetation and beach habitat. Only moderate variation in these habitat features was demonstrated among years of colonization. The factors causing these preferences appear to be protection from mammalian...

The ecology of the soft-bottom benthos of San Francisco Bay: a community profile The ecology of the soft-bottom benthos of San Francisco Bay: a community profile
This profile, part of a series of profiles concerning coastal habitats of the United States, is a detailed examination of the soft-bottom benthos of San Francisco Bay. A U.S. Fish and Wildlife Service and California Department of Fish and Game report (1979) entitled "Protection and Restoration of San Francisco Bay Fish and Wildlife Habitat" provides clear recognition of the importance of
