Organic compounds downstream from a treated-wastewater discharge near Dallas, Texas, March 1987 Organic compounds downstream from a treated-wastewater discharge near Dallas, Texas, March 1987
Water and streambed-sediment samples were collected on March 9 and 10,1987 from one site upstream and three sites downstream of the discharge from a municipal wastewater-treatment plant on Rowlett Creek near Dallas, Texas. To extract and separate organic compounds, purgeand-trap, closed-loop stripping, and pH-adjusted solvent extraction methods were used for water samples; and a Soxhlet...

Ground-water conditions in Georgia, 1993 Ground-water conditions in Georgia, 1993
Ground-water conditions during 1993 and recent ground-water level and quality trends in Georgia were evaluated using data from precipitation, ground-water, and ground-water quality monitoring networks. Data for 1993 included in this report are from precipitation records from 10 National Weather Service stations, continuous water-level records from 72 wells, and chloride analyses from 13...

Production and decomposition of Spartina patens in a degrading coastal marsh Production and decomposition of Spartina patens in a degrading coastal marsh
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m2 yr-1 during 1991 and 1,696 g m-1 yr-1 during 1992. The relative decomposition rate of S. patens stems was -0.001152 g g-1 d-1 which may be restated as a half life of 395 days. Both production and decomposition rates for this area are...

Diet differences in Redheads from nearshore and offshore zones in Louisiana Diet differences in Redheads from nearshore and offshore zones in Louisiana
Habitat management decisions for diving ducks in winter are limited by the lack of information concerning their use of nearshore and offshore zones. Therefore, we compared diets of redheads (Aythya americana) collected from nearshore (n = 206) and offshore (n = 72) zones during winters at the Chandeleur Islands, Louisiana, 1987-89. A greater (P 0.05) proportion of redheads from nearshore...

Nesting habitat of Belding’s Savannah sparrows in coastal salt marshes Nesting habitat of Belding’s Savannah sparrows in coastal salt marshes
Although the Belding’s Savannah sparrow (Passerculus sandwichensis beldingl) is listed as endangered in California, little is known about the factors that affect its abundance and distribution. Numbers of breeding pairs, nesting territory sizes, and vegetation characteristics were measured at fourteen study plots in two southern California coastal wetlands, Tijuana Estuary and Los...
