Synecology of a Virginia salt marsh
In the spring and summer of 1964 a salt marsh in Gloucester County, Virginia, was analyzed using random quadrat sampling. Synthetic treatments were employed to evaluate data and were correlated with observed differences in elevation. Floristic data indicate the Virginia salt marshes show closer similarity to marshes north of Chesapeake Bay than those south of Chesapeake Bay. Correlation of florist

Effects of urban development on floods in northern Virginia
Graphical and mathematical relations are presented to estimate the flood-peak magnitudes having recurrence intervals ranging up to 100 years for drainage basins with various degrees of urban or suburban development. Five independent variables are required for use of the relations. They are the size, length, and slope of the basin, which may be measured from maps, and the percentage of impervious s

Incidence of malaria in a wintering population of canvasbacks (Aythya valisineria) on Chesapeake Bay
Canvasback ducks wintering on Chesapeake Bay had a 6% incidence of Leucocytozoon sirnondi and 2% incidence of Haemoproteus. Sub-inoculation of whole blood into Pekin ducklings produced a Plasmodium infection rate of 31%. Females were more frequently infected (12/22) than males (15/68). The parasite was identified as P. circumflexum.

An outbreak of fowl cholera in waterfowl on the Chesapeake Bay
An outbreak of fowl cholera (Pasteurella multocida infection) occurred in waterfowl wintering on the Chesapeake Bay during February to March 1970. Losses were primarily confined to sea ducks: oldsquaws (Clangula hyemalis), white-winged scoters (Melanitta deglandi), goldeneyes (Bucephala clangula), and buffleheads (Bucephala albeola).

Monthly surface-water inflow to Chesapeake Bay
This report presents a convenient and rapid means of estimating, on either a monthly or a yearly basis, the inflow from surface streams to Chesapeake Bay. The method was developed as a working base for the release entitled "Estimated stream discharge entering Chesapeake Bay" prepared by the U. S. Geological Survey in cooperation with the States of Maryland, Pennsylvania, and Virginia. This release
