The effects of grazers and light penetration on the survival of transplants of Vallisneria americana Michs in the tidal Potomac River, Maryland The effects of grazers and light penetration on the survival of transplants of Vallisneria americana Michs in the tidal Potomac River, Maryland

Poor light penetration and grazing are among the factors potentially responsible for the lack of submersed aquatic macrophytes in the tidal Potomac River. Between 1980 and 1983, plugs, springs and tubers of Vallisneria americana Michx were transplanted from the oligohaline Potomac Estuary to six sites in the freshwater tidal Potomac River. Transplants made in 1980 and 1981 were generally

Analysis of potential yield per recruit for striped bass produced in Chesapeake Bay Analysis of potential yield per recruit for striped bass produced in Chesapeake Bay

The yield of striped bass (Morone saxatilis) in biomass and numbers was estimated for constant recruitment of young fish into the population on the basis of vital statistics of the Maryland stock. Separate computations were performed for males, females, and sexes combined. Yield in biomass per individual entering the population was highest when the minimum legal length was in the range...

Organochlorine pesticide, polychlorobiphenyl, and mercury residues in bald eagle eggs – 1969-79 – And their relationships to shell thinning and reproduction Organochlorine pesticide, polychlorobiphenyl, and mercury residues in bald eagle eggs – 1969-79 – And their relationships to shell thinning and reproduction

Bald eagle (Haliaeetus leucocephalus) eggs were collected in 14 States in 1969–79 and analyzed for organochlorine pesticides, polychlorobiphenyls, and mercury. Moderate shell thinning occurred in eggs from several areas. Eggs from the Chesapeake Bay area contained the highest residue levels of most organochlorines. DDE was detected in all eggs; other organochlorines were detected less...

Feeding flights of nesting wading birds at a Virginia colony Feeding flights of nesting wading birds at a Virginia colony

Feeding flights of Snowy Egrets (Egretta thula), Tricolored Herons (E. tricolor), Little Blue Herons (E. caerulea), and Cattle Egrets (Bubulcus ibis) were monitored at a small nesting colony near Chincoteague, Virginia during late May and June 1979. All four species varied their flight directions over a series of days. Cattle Egrets oriented in a different direction (toward uplands) from...

Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980 Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980

The chemical composition of bottom sediments and their associated pore waters from the tidal Potomac River and Estuary was studied from May 1978 through June 1980. Pore waters were routinely analyzed for pH, Eh, alkalinity, and concentrations of sulfide, sulfate, phosphate, carbon, ammonium, silica, iron, manganese, chloride, sodium, potassium, calcium, and magnesium. Porosity, weight...
