Hydrologic processes controlling sulfate mobility in a small forested watershed Hydrologic processes controlling sulfate mobility in a small forested watershed
Hydrologic controls on sulfate mobility were investigated in a forested catchment in the Georgia Piedmont using a watershed mass balance approach. Variations in annual sulfate export were governed primarily by differences in runoff rather than by differences in sulfate deposition or in total annual precipitation. However, 2 years with similar total runoff had substantially different...

Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela
The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted local distribution and habitat use for 40 species of diurnal...

Relation among cytochrome P450, AH-active PCB congeners and dioxin equivalents in pipping black-crowned night-heron embryos Relation among cytochrome P450, AH-active PCB congeners and dioxin equivalents in pipping black-crowned night-heron embryos
Pipping black-crowned night-heron (Nycticorax nycticorax) embryos were collected from a relatively uncontaminated site (next to Chincoteague National Wildlife Refuge, VA) and three polluted sites (Cat Island, Green Bay, Lake Michigan, WI; Bair Island, San Francisco Bay, CA; West Marin Island, San Francisco Bay, CA). Hepatic cytochrome P-450-associated monooxygenases and cytochrome P-450...

Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals
Elevated levels of cadmium in Pacific walrus (Odobenus rosmarus divergens) and northern fur seals (Callorhinus ursinus) have been reported in populations from the Bering Sea (Goldblatt & Anthony, 1983; Taylor et al., 1989). Russian and US authorities are concerned because of the possible health hazards from consuming pinniped meat harvested for subsistence peoples. The effects of cadmium...

Symptoms and circumstances associated with bites by the brown tree snake (Colubridae: Boiga irregularis) on Guam Symptoms and circumstances associated with bites by the brown tree snake (Colubridae: Boiga irregularis) on Guam
A review of 94 cases of snakebite by the brown tree snake, Boiga irregularis, in Guam spanning a two year period shows a high proportion (80%) involve victims bitten while sleeping in their homes at night. Some bites apparently involve attempts to feed on small children. Of all children less than 1 yr old that were bitten in a two year period, infants 1-3 mo old comprised 82%. The...

Diurnal habitat use of American woodcock wintering along the Atlantic coast Diurnal habitat use of American woodcock wintering along the Atlantic coast
The long-term decline of the American woodcock (Scolopax minor) population led us to investigate diurnal habitat use with radiotelemetry on the wintering grounds. Sites included the coastal plain of Georgia (1989-1991), South Carolina (1988-1989), and Virginia (1991-1992). Habitat use was not explained by age, sex, or date during the winter, but individuals used habitat differently (P 0...
