Ground-water discharge and base-flow nitrate loads of nontidal streams, and their relation to a hydrogeomorphic classification of the Chesapeake Bay watershed, middle Atlantic Coast Ground-water discharge and base-flow nitrate loads of nontidal streams, and their relation to a hydrogeomorphic classification of the Chesapeake Bay watershed, middle Atlantic Coast
Existing data on base-flow and groundwater nitrate loads were compiled and analyzed to assess the significance of groundwater discharge as a source of the nitrate load to nontidal streams of the Chesapeake Bay watershed. These estimates were then related to hydrogeomorphic settings based on lithology and physiographic province to provide insight on the areal distribution of ground-water...

Experimental analysis and simulation modeling of forest management impacts on wood thrushes, Hylocichla mustelina Experimental analysis and simulation modeling of forest management impacts on wood thrushes, Hylocichla mustelina
North American Breeding Bird Survey data show that wood thrush (Hylocichla mustelina) populations in eastern U.S. forests have declined 1.8% per year during 1966-95. The declining quality of breeding forest tracts in North America is one possible cause for the apparent decline of some neotropical migratory birds, such as the wood thrush. In Georgia, however, wood thrush populations have...

Lithium Lithium
The lithium industry can be divided into two sectors: ore concentrate producers and chemical producers. Ore concentrate producers mine lithium minerals. They beneficiate the ores to produce material for use in ceramics and glass manufacturing.

Yields and trends of nutrients and total suspended solids in nontidal areas of the Chesapeake Bay basin, 1985-96 Yields and trends of nutrients and total suspended solids in nontidal areas of the Chesapeake Bay basin, 1985-96
Excessive concentrations of nutrients and suspended solids in water adversely affect water quality in the Chesapeake Bay. High levels of nutrients in the Bay result in algal blooms and suspended solids reduce water clarity, both of which decrease the amount of light reaching submerged aquatic vegetation (SAV). The die off and decomposition of algae and SAV deplete oxygen supplies in the...

Estimating population parameters for northern and southern breeding populations of Canada geese Estimating population parameters for northern and southern breeding populations of Canada geese
Canada geese (Branta canadensis) have been managed largely as a migratory resource. In the 1960's, Canada goose flocks were restored to historic breeding ranges in the United States and southern Canada to enhance recreational opportunity for observation and harvest. These populations of southern breeding geese have rapidly expanded, increasing conflicts with social and economic interests...

Field evidence for linking Altosid applications with increased amphibian deformities in southern leopard frogs [abstract] Field evidence for linking Altosid applications with increased amphibian deformities in southern leopard frogs [abstract]
During the summer of 1997 we repeatedly sprayed Altosid, a formulation of 4% methoprene used for mosquito control, on six constructed macrocosms. Six additional macrocosms were sprayed with Abate4E, containing the organophosphate pesticide temephos, and six were sprayed with water (controls). The wetlands were created on an impermeable foundation for research purposes and averaged 215 m2...

Renewal of voluntary feeding by wild‐caught Atlantic sturgeon juveniles in captivity Renewal of voluntary feeding by wild‐caught Atlantic sturgeon juveniles in captivity
A modification of previously documented force‐feeding procedures resulted in the renewal of appetite by several wild‐caught juvenile Atlantic sturgeon Acipenser oxyrinchus. Four of four fish under controlled laboratory conditions responded positively to this technique within 1 month. These fish exhibited negative mean growth rates of −2.71 g/d before force‐feeding and gained an average...
