Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands? Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands?
White band disease (WBD) ravaged Acropora palmata (elkhorn coral) on many coral reefs in the Caribbean in the late 1970’s and 1980’s, including those around St. John and St. Croix, U. S. Virgin Islands—USVI (Gladfelter 1982, Rogers 1985). Quantitative data, photographs, and anecdotal observations indicate WBD killed large stands of elkhorn coral in the USVI from about 1976 until sometime...

Growth and nutrition of baldcypress families planted under varying salinity regimes in Louisiana, USA Growth and nutrition of baldcypress families planted under varying salinity regimes in Louisiana, USA
Saltwater intrusion from the Gulf of Mexico is one important factor in the destruction of baldcypress (Taxodium distichum (L.) Rich.) swamps along the Louisiana Gulf Coast, USA. Recent restoration efforts have focused on identification of baldcypress genotypes with greater tolerance to saline conditions than previously reported. To date, salt tolerance investigations have not been...

Surface water quality of the major drainage basins of Big Thicket National Preserve Surface water quality of the major drainage basins of Big Thicket National Preserve
Surface water quality was monitored at 19 stations (2-4 week intervals) in six drainage basins of Big Thicket National Preserve of east Texas between 1996 and 1999. The parameters monitored were temperature, dissolved oxygen, pH, conductivity, current speed, light attenuation, chlorophyll a and concentrations of ammonium, ortho-phosphate, nitrate and nitrite. The best water quality (low...

Water resources data Texas, water year 1999, volume 3. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins Water resources data Texas, water year 1999, volume 3. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
Water-resources data for the 1999 water year for Texas are presented in six volumes, and consist of records of stage, discharge, and water quality of streams and canals; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. Volume 3 contains records for water discharge at 78 gaging stations; stage only at 7 gaging stations...

Description and identification of American Black Duck, Mallard, and hybrid wing plumage Description and identification of American Black Duck, Mallard, and hybrid wing plumage
We developed a key to identify wings of hybrids between American Black Ducks (Anas rubripes) and Mallards (A. platyrhynchos). Material for analysis included review of historical descriptions dating from the late 1700's, older museum collections in Europe and North America, wings collected from hunters in North America and Great Britain, birds banded in Canada and the United States, and a...

1890 and 1990 Bathymetry of Florida Bay 1890 and 1990 Bathymetry of Florida Bay
This Open File Report contains bathymetric data collected in Florida Bay by the US Geological Survey, South Florida Place-Based Studies Program using SANDS (System for Accurate Nearshore Depth Surveying). SANDS is a USGS developed, high precision bathymetric system which integrates depth soundings, boat motion, and GPS positioning needed for nearshore bathymetric mapping. Data...

Fire ecology in the southeastern United States Fire ecology in the southeastern United States
Fire has played an important role in the structure of natural ecosystems throughout North America. As a natural process, fire helps clear away dead and dying plant matter and increases the production of native species that occur in fire prone habitats. It also reduces the invasion of exotic species and the succession to woody species in pitcher plant bogs, pine savannas, coastal prairies...

Velocity and stage data collected in a laboratory flume for water-surface slope determination using a pipe manometer Velocity and stage data collected in a laboratory flume for water-surface slope determination using a pipe manometer
U.S. Geological Survey (USGS) hydrologists and ecologist are conducting studies to quantify vegetative flow resistance in order to improve numerical models of surface-water flow in the Florida Everglades. Water-surface slope is perhaps the most difficult of the flow resistance parameters to measure in the Everglades due to the very low gradients of the topography and flow. In an effort...
