Effects of prolacton chloride cells opercular membrane of seawater-adapted tilapia

Effects of prolactin on morphology and numbers of chloride cells in the opercular membrane of seawater-adapted tilapia (Oreochromis mossambicus) have been examined. Following five daily injections of ovine prolactin at a dose of 10 μg · g body wt−1, blood samples were taken and opercular membranes were removed and stained with a fluorescent mitochondrial dye (dimethylaminostyrylethylpyridiniumiodi

Hydrology and the hypothetical effects of reducing nutrient applications on water quality in the Bald Eagle Creek Headwaters, southeastern Pennsylvania prior to implementation of agricultural best-management practices

The report characterizes a 0.43-square-mile agricultural watershed in York County, underlain by albite-chlorite and oligoclase-mica schist in the Lower Susquehanna River basin, that is being studied as part of the U.S. Environmental Protection Agency's Chesapeake Bay Program. The water quality of Bald Eagle Creek was studied from October 1985 through September 1987 prior to the implementation of B

Ground-water levels, flow, and quality in northwestern Elkhart County, Indiana, 1980-89

Ground-water data were collected in northwestern Elkhart County, Indiana, from 1980 through 1989 to monitor hydrologic conditions and to provide information necessary for waterresources managers to evaluate the ground-water resources in this area. The area of study includes a closed industrial landfill and several areas of industrial and municipal pumping. Water levels were measured twice a year i

Water-resources data for North Fork Bens Creek, Somerset County, Pennsylvania, August 1983 through September 1988

Basin and climatological characteristics, quality-assurance data and results, and water-resources data for North Fork Bens Creek, in Somerset County, Pennsylvania are available from August 1983 through September 1988. The lowest temperature (-30. 0 C) was recorded during January 1985, and the highest temperature (36.7 C) was recorded during July 1988. Snowfall accumulates mostly during January and

Large-scale coastal evolution of Louisiana's barrier islands

The prediction of large-scale coastal change is an extremely important, but distant goal. Here we describe some of our initial efforts in this direction, using historical bathymetric information along a 150 km reach of the rapidly evolving barrier island coast of Louisiana. Preliminary results suggest that the relative sea level rise rate, though extremely high in the area, has played a secondary

A giant submarine slope failure on the northern insular slope of Puerto Rico

A large amphitheater-shaped scarp, approximately 55 km across, was imaged on the northern insular slope of Puerto Rico using long-range sidescan sonar and bathymetric data. This scarp results from the removal of more than 1500 km3 of Tertiary strata. A review of seismic-reflection profiles, stratigraphic data, and subsidence models of the northern insular margin of Puerto Rico were used to infer t
