Winter ecology of the endangered golden-cheeked warbler Winter ecology of the endangered golden-cheeked warbler

We studied the ecology of the Golden-cheeked Warbler (Dendroica chrysoparia) during three winter seasons, 1995-1998, in Honduras, Guatemala, and Mexico. Individuals of this species occurred almost exclusively as members of mixed-species flocks, occupying sites with greater densities of encino oak and ground cover and fewer pines than random sites. Most foraging observations were recorded...

Physical stratigraphy, paleontology, and magnetostratigraphy of the USGS-Santee Coastal Reserve core (CHN-803), Charleston County, South Carolina Physical stratigraphy, paleontology, and magnetostratigraphy of the USGS-Santee Coastal Reserve core (CHN-803), Charleston County, South Carolina

The Santee Coastal Reserve core, a 545-ft-deep corehole in northeastern Charleston County, South Carolina, recovered sediments of Late Cretaceous, Paleocene, Eocene, and Quaternary age. The deepest sediments, the Donoho Creek Formation (545-475.7 ft), consist of 69.3 ft of muddy calcareous sand of marine origin. This formation is placed within the upper Campanian calcareous nannofossil...

Radium in ground water from public-water supplies in northern Illinois Radium in ground water from public-water supplies in northern Illinois

Concentrations of the naturally occurring radioactive isotopes radium-226 and radium-228 in excess of the U.S. Environmental Protection Agency standard for drinking water of 5 picocuries per liter have been detected in water from deep aquifers used for public supply that underly parts of northern Illinois. Radium, a known carcinogen, has the potential to cause bone and sinus cancer if...

Ground-water conditions in Georgia, 1998 Ground-water conditions in Georgia, 1998

Ground-water conditions in Georgia during 1998 and for the period of record were evaluated using data from U.S. Geological Survey ground-water-level and ground-water-quality monitoring networks. Data for 1998 included in this report are from continuous water-level records from 130 wells and chloride analyses from 14 wells. Data from one well is incomplete because data collection was...

Status and distribution of the angonoka tortoise (Geochelone yniphora) of western Madagascar Status and distribution of the angonoka tortoise (Geochelone yniphora) of western Madagascar

From 1993 to 1995, field surveys were conducted in western Madagascar to assess the current status of the angonoka tortoise (Geochelone yniphora) in the wild. Tortoise presence was documented at 10 of 11 localities surveyed. These localities represent at least five populations, all within a 30-km radius of Baly Bay, near the town of Soalala. The populations occur on fragments of habitat...

Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina

In 1998, the relative susceptibility of ground water in Orange County, North Carolina,to contamination from surface and shallow sources was evaluated. A geographic information system was used to build three county-wide layers--soil permeability, land use/land cover, and land-surface slope. The harmonic mean permeability of soil layers was used to estimate a location's capacity to...
