Species specific phytoplankton production rates during a spring diatom bloom in Yaquina Bay, Oregon

Creator:: McMurray, Gregory R., 1925-
Abstract:: A simplified autoradiographic method for estimating species-specific phytoplankton production rates in mixed natural communities was evaluated in the laboratory and employed in the field. Laboratory experiments were designed to test the reliability and variability of the simplified method. Assays of ¹⁴C uptake by liquid scintillation spectrometry were used to evaluate...

Effects of micro-nutrients and major nutrients on the growth and species composition of natural phytoplankton populations

Creator:: Frey, Bruce E.
Abstract:: Large-volume (20-liter) bioassays were carried out in order to assess the effects of major nutrients and micro-nutrients on natural phytoplankton populations in water collected from a site close to the mouth of Yaquina Bay, Oregon. Seven long-term experiments were conducted during the years 1975-1976. A stripping technique employing activated carbon...

The dynamics of an isolated population of Acartia tonsa Dana (Copepoda) in Yaquina Bay, Oregon

Creator:: Johnson, John Kenneth
Abstract:: In the upper estuary of Yaquina Bay, Oregon, there is an annual population explosion of Acartia tonsa, (Dana) a calanoid copepod, during the months of July, August and September, followed by a rapid decline to virtual extinction in November. The restricted estuarine distribution affords an excellent opportunity to study the...
