Reports
Oyster setting in Virginia River systems dropped to the lowest level on record during 1972. Spatfall studies indicate this poor condition to be the direct result of the effects of tropical storm Agnes.

The Effects Of "Hurricane Agnes" On The Benthic Diversity In The Hampton Ronds, Virginia, Area, Jeffrey Hyland
Reports
Benthic communities are normally both physically and biologically regulated: However, if an interaction of the physical environment becomes significant, then the community becomes predominantly physically regulated. The arrival of "Hurricane Agnes", presumably causing a considerable reduction in salinity in nearby estuaries, would appear to create a significant physical stress on a benthic community. According to the "theory of environmental stability" (Sanders 1968) , the less stable the environmental parameters - such as salinity, oxygen., and temperature - the fewer species present. Thus, one might expect a decrease in benthic community diversity, due to the occurrence of such a natural disaster …
