Production Of A Population Of The Stout Razor Clam (Tagelus Plebeius Solander) In A Virginia Estuary, Mark James Grussendorf

OES Theses and Dissertations

The annual net secondary production of the stout razor clam, Tagelous plebeius, was estimated at three sites on an intertidal sand flat at Lynnhaven Inlet, Virginia. Samples were taken at six week intervals for one year. The range of net production (P), mean annual biomass (B), and P/B ratios was 18.3-28.7 g m^-2year^-1, 27.2-53.3 g m^-2, and 0.54-0.67, respectively. The total biomass did not show significant seasonal variation though differences between sites were significant. Production varied temporally but was not significantly different between sites.

A Study To Determine The Effect Of The Increasing Minimum Wage On The Placement And Retention Of Cooperative Education Students In The City Of Portsmouth, Sidney Jordan Duck Iii

OTS Master's Level Projects & Papers

The primary purpose of this study was to determine: 1. the effect of the increasing minimum wage on the placement of cooperative education students; 2. whether the increase would result in reduced retention of the regular number of cooperative education students employed; 3. whether any on cooperative education program was affected more than the others with regard to the increase in the minimum wage.

Animal-Sediment Relationship Study Of The Western Branch Of The Lynnhaven River, Charles Perry Seymour

Biological Sciences Theses & Dissertations

The animal-sediment relationships of the marine benthic infauna of an estuarine river system, Lynnhaven River, Virginia Beach, Virginia, were studied at six sites, sampled bimonthly for one year. Six species were found to dominate all of the sampling periods and sites for the year. The greatest number of individuals, biomass, and species were found at the sand sites. Deposit feeders were recorded in greater number than suspension feeders at both the sand and the mud sites.

Cluster and nodal analyses were successful in demonstrating animal-sediment relationships for the intertidal regions of the river system.
