Clearcut stand size and scrub-successional bird assemblages Clearcut stand size and scrub-successional bird assemblages

We investigated the effects of clearcut stand size on species richness, reproductive effort, and relative abundance of scrub-successional birds and the entire bird assemblage at the Savannah River Site in South Carolina. We used standardized mist-net grids to mark and recapture birds in clearcuts replanted with longleaf pine (Pinus palustris) in stands of 2 to 57 ha that were two to six...

Bioassessment of Hollis Creek, Oktibbeha County, Mississippi Bioassessment of Hollis Creek, Oktibbeha County, Mississippi

Physical, chemical and biological components at five stations on Hollis Creek, Oktibbeha County, Mississippi were evaluated using Rapid Bioassessment Protocols (RBP) and the Sediment Quality Triad (SQT) on August 24-26, 1999, in order to assess potential biological impacts from the Starkville Waste Water Treatment Facility (WWTF) on downstream resources. Two stations were selected above...

Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon

High-resolution seismic-reflection profiles (3.5 kHz) show that a distinctive, widespread reflection occurs in the sediments beneath Upper Klamath Lake, Oregon. Coring reveals that this reflection is formed by Mazama tephra (MT), about 7 ka in age. The MT horizon is faulted in many places and locally displaced by as much as 3.1 m. Differential displacement of multiple horizons indicates...

Climatic variability in the eastern United States over the past millennium from Chesapeake Bay sediments Climatic variability in the eastern United States over the past millennium from Chesapeake Bay sediments

Salinity oscillations caused by multidecadal climatic variability had major impacts on the Chesapeake Bay estuarine ecosystem during the past 1000 yr. Microfossils from sediments dated by radiometry (14C, 137Cs, 210Pb) and pollen stratigraphy indicate that salinity in mesohaline regions oscillated 10-15 ppt during periods of extreme drought (low fresh-water discharge) and wet climate...

Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay

Recent, unmixed sediments from mud banks of central Florida Bay were dated using 210Pb/226Ra, and chronologies were verified by comparing sediment lead temporal records with Pb/Ca ratios in annual layers of coral (Montastrea annularis) located on the ocean side of the Florida Keys. Dates of sediment lead peaks (1978±2) accord with prior observations of a 6 year lag between the occurrence...

Water Resources Data Massachusetts and Rhode Island Water Year 1999 Water Resources Data Massachusetts and Rhode Island Water Year 1999

INTRODUCTION The Water Resources Division of the U.S. Geological Survey, in cooperation with State agencies, obtains a large amount of data pertaining to the water resources of Massachusetts and Rhode Island each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the States. To...
