Effects of urban development on floods in northern Virginia 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...

Incidence of malaria in a wintering population of canvasbacks (Aythya valisineria) on Chesapeake Bay 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.

Lead poisoning in a sample of Maryland mourning doves Lead poisoning in a sample of Maryland mourning doves

A sick mourning dove (Zenuidura macroura) collected in Maryland with 2 lead shot in the gizzard showed acid-fast intranuclear inclusion bodies in the kidney tubular cells. The liver and the tibia contained 72 ppm and 187 ppm lead (wet weight) respectively. Four gizzards from 62 doves killed by hunters contained lead shot. The lead content of 43 dove livers ranged from 0.4-14.0 ppm (wet...
