Macrobenthic Communities Of An Industrialized Seaport Ecosystem: The Southern Branch Of The Elizabeth River, Virginia, Steven D. Hawthorne
Macrobenthic Communities Of An Industrialized Seaport Ecosystem: The Southern Branch Of The Elizabeth River, Virginia, Steven D. Hawthorne
Biological Sciences Theses & Dissertations
Macrobenthic invertebrates of an industrialized seaport ecosystem were studied seasonally from October, 1977 through July, 1978. Five stations were selected along the Southern Branch of the Elizabeth River, Virginia. The stations ranged from an area of heavy industrialization to a non-urbanized environment. At each station, bottom water was measured for salinity, temperature, dissolved oxygen, and pH. Within each sampling area, macrobenthic infauna! invertebrates were collected from in and out of channel sites along with sediment samples for various types of physicochemical analysis.
Community structure was spatially homogeneous at station sites and throughout the stations along the River. Slightly acidic pH …

Observations On The Distribution And Composition Of Zooplankton In Portions Of The Intracoastal Waterway, Virginia, O. Clair Hillard Jr.
Observations On The Distribution And Composition Of Zooplankton In Portions Of The Intracoastal Waterway, Virginia, O. Clair Hillard Jr.
Biological Sciences Theses & Dissertations
Five stations were established in the Southern Branch of the Elizabeth River, the Dismal Swamp Canal, the Albemarle and Chesapeake Canal and the North Landing River. Representative samples of zooplankton were taken from October 1971 to June 1972. A. total of 57 species were identified and discussions regarding seasonal distribution in relation to physical factors and circulation are presented.
The composition of the zooplankton was found to fluctuate greatly due to the variables characteristic of the study area. The combined effect of tidal flow with freshwater input in conjunction with drainage from the Great Dismal Swamp, results in isolated populations …

Distribution Of Foraminiferida In An Estuarine Marsh System, Charles Warren Norton
Distribution Of Foraminiferida In An Estuarine Marsh System, Charles Warren Norton
Dissertations, Theses, and Masters Projects
Foraminiferal faunas in marshes and distributary channels of the James River estuary, Virginia, disclose several facies. The channel facies, primarily Ammobaculites crassus, and A. sp. A, typical of estuaries in Chesapeake Bay and other brackish areas are readily distinguishable freom the march facies. Marshes are divisible laterally by changes in the relative proportions of marsh species such as Miliammina fusca, Ammoastuta salsa, and Haplophragmoides hancocki.Changes along the longitudinal estuarine salinity gradient are discernable in both tidal creeks and marsh. Channels exhibit a longitudinal gradient from a freshwater thecamoebinid facies through an upper and mid-estuarine Ammobaculites facies to a higher salinity …
