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

A pollution history of Chesapeake Bay
Present day anthropogenic fluxes of some heavy metals to central Chesapeake Bay appear to be intermediate to those of the southern California coastal region and those of Narragansett Bay. The natural fluxes, however, are in general higher. On the bases of Pb-210 and Pu-239 + 240 geochronologies and of the time changes in interstitial water compositions, there is a mixing of the upper 30 or so cent

Changes in submerged aquatic macrophyte populations at the head of Chesapeake Bay, 1958-1975
Submerged aquatic plant populations in the Susquehanna Flats of the Chesapeake Bay were followed for 18 years. An exotic species, eurasian water milfoil, Myriophyllum spicatum, increased dramatically from 1958 to 1962; at the same time the dominant native species declined. After 1962, milfoil populations declined and the native rooted aquatics gradually began to return to their former levels. In t

Exceedance probability-depth relationships of floods for Maryland streams west of Chesapeake Bay
A procedure is outlined for estimating the depths of floods of specified exceedance probabilities for Maryland streams west of the Chesapeake Bay. Data required for use of the estimating procedure are the stream's location in one of three flood-depth regions and the drainage area. Regression equations developed for depth estimation of the 50-, 20-, 10-, 2-, and 1-percent floods have standard error

Heavy-mineral variability in bottom sediments of the lower Chesapeake Bay, Virginia
Heavy minerals in bottom-sediment samples of the lower Chesapeake Bay show distribution patterns and interrelationships that denote characteristic mineral suites associated with defined geographic provinces. The Baymouth province has a garnet-hornblende-pyroxene suite, which is largely attributed to the influx of littoral and shelf sediments; the Eastern Shore province has a similar suite, derived
