Nitrogen Versus Phosphorus Limitation for Growth of an Estuarine Population of Eelgrass (Zostera marina L)

Murray L, Dennison WC, and Kemp WM ·
1992

The relative importance of nitrogen (N) and phosphorus (P) limitation for growth and biomass accumulation in an estuarine population of eelgrass (Zostera marina L.) was examined by in situ additions of nitrogen (+N), phosphorus (+P) and nitrogen plus phosphorus (+N+P) to sediments at low and high loading rates. Nitrogen treatments resulted in no significant increases in leaf tissue N levels and only a small increase in the N content of root plus rhizome tissues.

Quantitative Feeding Ecology of the Hydromedusan Nemopsis-Bachei in Chesapeake Bay

Purcell JE and Nemazie DA ·
1992

We determined feeding rates of the hydromedusan Nemopsis bachei L. Agassiz in the mesohaline region of Chesapeake Bay, USA during the spring of 1989 and 1990 from gut contents, digestion rates and abundances of medusae and zooplankton. The medusae consumed primarily copepodites of Acartia tonsa, selecting against naupliar stages.
