Historical subsidence and wetland loss in the Mississippi delta plain Historical subsidence and wetland loss in the Mississippi delta plain
Five representative areas of the Mississippi River delta plain were investigated using remote images, marsh elevations, water depths, sediment cores, and radiocarbon dates to estimate the timing, magnitudes, and relative rates of marsh erosion and land subsidence at geological and historical time scales. In the Terrebonne-Lafourche region of rapid interior-wetland loss, former marshes...

Effects of prescribed fire in the coastal prairies of Texas Effects of prescribed fire in the coastal prairies of Texas
Prescribed fire is widely applied for habitat management in coastal ecosystems. Fire management plans typically list a variety of objectives for prescribed burning, including succession management, promotion of native flora and fauna, providing habitat for species of importance, wildfire risk reduction (fuels management), as well as reduction and/or prevention of invasive species. In...

Using radar to understand migratory birds and their habitats: Critical needs for the Gulf of Mexico Using radar to understand migratory birds and their habitats: Critical needs for the Gulf of Mexico
Nearly all Neotropical migratory landbird species of the eastern United States as well as many western species use Louisiana and the northern Gulf of Mexico coast during their transcontinental migrations each spring and fall. Radar has determined that hundreds of millions of birds make the nocturnal crossing of the Gulf of Mexico resulting in daily flights of as many as 2.5 million...

Migratory bird pathways and the Gulf of Mexico: Importance of Louisiana's coast Migratory bird pathways and the Gulf of Mexico: Importance of Louisiana's coast
Because of its geographic position, Louisiana plays an important role in the hemispheric-scale phenomenon known as the Nearctic-Neotropical bird migration system. Each year millions of landbirds migrate across or near to the coast of the Gulf of Mexico. Birds migrate in large, broad fronts that sometimes exceed 2 million individuals, and there is an advantage for them to take a direct...

Grazing by the intertidal gastropod Melampus coffeus greatly increases mangrove leaf litter degradation rates Grazing by the intertidal gastropod Melampus coffeus greatly increases mangrove leaf litter degradation rates
Melampus coffeus, a pulmonate gastropod, forages for mangrove leaf litter at low tide and climbs tree trunks to avoid inundation during high tide. Unlike many grazers, these snails can assimilate mangrove leaf material. At Boca Ceiga Bay, Florida, densities of adult snails were high (>100 snails m–2) throughout a 130 m wide intertidal zone. A mark–recapture study indicated that over the...

Communicating science Communicating science
For science to have an impact, it must be communicated and easily accessible. The USGS National Wetlands Research Center communicates its research findings through several ways: publishing, the Web, the library, and education and outreach.

Leaf optical property changes associated with the occurrence of Spartina alterniflora dieback in Coastal Louisiana related to remote sensing mapping Leaf optical property changes associated with the occurrence of Spartina alterniflora dieback in Coastal Louisiana related to remote sensing mapping
In order to provide a remote sensing solution that would detect both the initial onset and monitor the early, as well as, the later stages of impact progression, changes in live leaf optical properties were compared along transects spanning impacted coastal Louisiana marsh sites. Green and red edge reflectance trends generally represented the early stages and fairly well the later stages...
