Structure Of A Subtidal Benthic Community Near Cape Charles, Virginia, R. Michael Ewing
Structure Of A Subtidal Benthic Community Near Cape Charles, Virginia, R. Michael Ewing
Biological Sciences Theses & Dissertations
Species composition, distribution, and abundance of benthic invertebrates of a subtidal community were examined at a location on the lower Delmarva Peninsula near Cape Charles, Virginia. Macrobenthos was sampled quarterly between June, 1977 and June, 1978 at nine sites along a transect in Old Plantation Creek and the adjacent offshore area. Spatial and temporal patterns of numerically important species are discussed.
Sampling sites and species were grouped by a numerical classification strategy which consisted of the Bray-Curtis similarity measure and group-average clustering. Three faunal assemblages were identified with the aid of constancy and fidelity nodal analyses: (1) a tidal creek …
Animal-Sediment Relationship Study Of The Western Branch Of The Lynnhaven River, Charles Perry Seymour
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.
