Article
T. N. Wiegner, Auteur ; S. P. Seitzinger, Auteur ; D. L. Breitburg, Auteur ; J. G. Sanders, AuteurResponses of autotrophic and heterotrophic processes to nutrients and trace elements were examined in a series of experimental estuarine food webs of increasing trophic complexity using twenty 1-m(3) mesocosms. Nutrients (nitrogen and phosphorus[...]
Article
G. F. Riedel, Auteur ; J. G. Sanders, AuteurBiogeochemical interactions between a suite of trace elements and nutrients were examined in a series of experimental mesocosm experiments to understand how multiple stressors affect estuarine environments and how these effects are modified by t[...]
Article
A. E. Laursen, Auteur ; S. P. Seitzinger, Auteur ; R. Dekorsey, Auteur ; J. G. Sanders, Auteur ; D. L. Breitburg, Auteur ; R. W. Osman, AuteurThe effects of nutrients, trace elements, and trophic complexity on benthic photosynthesis and respiration were studied in the Paxtuxent River estuary near St. Leonard, Maryland. Experiments were conducted over three years (1995-1997) in mesocos[...]
Article
G. F. Riedel, Auteur ; J. G. Sanders, Auteur ; D. L. Breitburg, AuteurWe examined individual and interactive effects of two stressors-nutrients (nitrogen [N] and phosphorus [P]) and trace elements (a mix of arsenic [As], copper [Cu], and cadmium [Cd], and in a second experiment also zinc [Zn] and nickel [Ni])-on p[...]
Article
G. F. Riedel, Auteur ; S. A. Williams, Auteur ; G. S. Riedel, Auteur ; C. C. Gilmour, Auteur ; J. G. Sanders, AuteurTrace element distributions, partitioning, and speciation were examined at 15 sites in the Patuxent River watershed from May 1995 through October 1997 to determine possible sources of brace elements to the river and estuary, to examine the relat[...]
Article
G. F. Riedel, Auteur ; G. R. Abbe, Auteur ; J. G. Sanders, AuteurConcentrations of copper (Cu), silver (Ag), and cadmium (Cd)in eastern oysters (Crassostrea virginica) from the upper Patuxent River estuary analyzed since 1986 (Cd since 1991) were high relative to concentrations in other sites in the United St[...]
Article
G. F. Riedel, Auteur ; J. G. Sanders, AuteurMeasurements of dissolved As, Cr, Cu, and Se using species-selective techniques were made in the tidal freshwater Delaware River at four sites in July 1991, January 1992, and March 1992. Concentrations of dissolved As, Ct, and Sr were generally [...]
