Ecology of a Maryland population of black rat snakes (Elaphe o. obsoleta)
Behavior, growth and age of black rat snakes under natural conditions were investigated by mark-recapture methods at the Patuxent Wildlife Research Center for 22 years (1942-1963), with limited observations for 13 more years (1964-1976). Over the 35-year period, 330 snakes were recorded a total of 704 times. Individual home ranges remained stable for many years; male ranges averaged at least 600 m

Water-quality monitoring of three major tributaries to the Chesapeake Bay: Interim data report
The U.S. Geological Survey is monitoring the water quality of three major tributaries to Chesapeake Bay at their fall lines to obtain estimates of constituent inputs potentially available to the bay. The monitoring sites are: Susquehanna River at Conowingo, Md.; Potomac River at Washington, D.C.; and James River at Cartersville, Va. Water-quality data collected from October 1978 to April 1980 are

Lead residues in sora rails from Maryland
During September and October, mi- grating sora rails (Porzana carolina) use tidal marshes of the Patuxent River in Maryland, where they have been hunted for many years. Spent shot accumulates in the marsh during the rail hunting sea- son, and some shot is ingested by the birds. Twelve percent of gizzards from rails collected at the marsh during 1965- 73 contained lead shot (Artmann and Martin 197

Seminar on water quality in the tidal Potomac River
In the interest of maintaining communication between researchers and managers concerned with the tidal Potomac River, the U.S. Geological Survey sponsored a Seminar on the Water Quality of the Tidal Potomac River. The Seminar was held on December 6 and 7, 1978, at the U.S. Geological Survey National Headquarters in Reston, Virginia. The Seminar was attended by 135 individuals representing 27 organ

Organochlorine residues and reproduction in the little brown bat, Laurel, Maryland - June 1976
Twelve of 43 pregnant little brown bats (Myotis lucifugus) collected at Montpelier Barn, Laurel, Maryland, gave birth to dead young. Eleven of these 12 dead neonates were abnormally small. Most of the stillbirths were attributable to unknown reproductive difficulties associated with first pregnancies, but four may have been due to high concentrations of polychlorinated biphenyls (PCB) in the newbo
