Debbie Warner, Stephen J. Lawrence
2005, Scientific Investigations Report 2005-5047
During 1997, the Dougherty County Health Department sampled more than 700 wells completed in the Upper Floridan aquifer in Dougherty County, Georgia, and determined that nitrate as nitrogen (hereinafter called nitrate) concentrations were above 10 milligrams per liter (mg/L) in 12 percent of the wells. Ten mg/L is the Georgia...

2005, Scientific Investigations Report 2005-5050
The U.S. Geological Survey, in cooperation with the New Mexico Environment Department, is investigating the pre-mining ground-water chemistry at the Molycorp molybdenum mine in the Red River Valley, New Mexico. The primary approach is to determine the processes controlling ground-water chemistry at an unmined, off-site but proximal analog. The Straight...
Estimation of agricultural pesticide use in drainage basins using land cover maps and county pesticide data
Naomi Nakagaki, David M. Wolock
2005, Open-File Report 2005-1188
A geographic information system (GIS) was used to estimate agricultural pesticide use in the drainage basins of streams that are studied as part of the U.S. Geological Survey?s National Water-Quality Assessment (NAWQA) Program. Drainage basin pesticide use estimates were computed by intersecting digital maps of drainage basin boundaries with an...

Wildfires caused extreme changes in the hydrologic, hydraulic, and geomorphologic characteristics of many Colorado drainage basins in the summer of 2002. Detailed assessments were made of the short-term effects of three wildfires on burned and adjacent unburned parts of drainage basins. These were the Hayman, Coal Seam, and Missionary Ridge...

Systematics of halogen elements and their radioisotopes in thermal springs of the Cascade Range, Central Oregon, Western USA
Shaul Hurwitz, Robert H. Mariner, Udo Fehn, Glen T. Snyder
2005, Earth and Planetary Science Letters (235) 700-714
This study quantifies the cycling of halogen elements through the Cascadia subduction zone based on the chemistry of thermal springs in the Central Oregon Cascade Range and of a mineral spring in the forearc (Willamette Valley). Considerations based on mass balances, element ratios, and 36Cl/Cl and 129I/I ratios suggest that halogens discharged...
Remote sensing sensitivity to fire severity and fire recovery
C.H. Key
2005, Conference Paper, Proceedings of the 5th International Workshop on Remote Sensing and GIS Applications to Forest Fire Management: Fire Effects Assessment
The paper examines fundamental ways that geospatial data on fire severity and recovery are influenced by conditions of the remote sensing. Remote sensing sensitivities are spatial, temporal and radiometric in origin. Those discussed include spatial resolution, the sampling time of year, and time since fire. For standard reference, sensitivities are...
Response from Soulé and Estes
Michael E. Soule, James A. Estes
2005, BioScience (55) 548-548
The letter from Kimberly Heiman points out the applicability of our framework to nonnative invasive species. Indeed, many alien species are changing the sign and increasing the amplitude of strong interactions in contemporary ecosystems, in some cases catastrophically. Invasive exotic species require much more attention at the policy and...
A landscape perspective for forest restoration
Thomas D. Sisk, Melissa Savage, Donald A. Falk, Craig D. Allen, Esteban Muldavin, Patrick McCarthy
2005, Journal of Forestry (103) 319-320
Forest managers throughout the West are anxiously seeking solutions to the problem of “large crown fires” - destructive blazes atypical of many forest types in the region. These wildfires have created a crisis mentality in management that has focused on rigid prescriptions for fuels reduction, rather than the restoration of...

Steven J. Hamilton
2005, Ecotoxicology and Environmental Safety (61) 313-326
The razorback sucker (Xyrauchen texanus) is listed as federally endangered throughout its range. A massive recovery effort by the Recovery Implementation Program for Endangered Fish Species in the Upper Colorado River Basin has focused its efforts in the upper Colorado River. The upper Colorado River basin also has two locations...

2005, San Francisco Estuary and Watershed Science (3)
Genetic variation at 11 microsatellite loci described population genetic structure for Oncorhynchus mykiss in the Central Valley, California. Spatial and temporal variation was examined as well as relationships between hatchery and putative natural spawning anadromous stocks. Genetic diversity was analyzed at two distinct spatial scales: fine-scale within drainage for five populations on...

Kelly P. Nevin, Dawn E. Holmes, Trevor L. Woodard, Erich S. Hinlein, David W. Ostendorf, Derek R. Lovely
2005, International Journal of Systematic and Evolutionary Microbiology (55) 1667-1674
Fe(III)-reducing isolates were recovered from two aquifers in which Fe(III) reduction is known to be important. Strain BemT was enriched from subsurface sediments collected in Bemidji, MN, USA, near a site where Fe(III) reduction is important in aromatic hydrocarbon degradation. Strains P11, P35T and P39 were isolated from...
Fire as a global ‘herbivore’: the ecology and evolution of flammable ecosystems
William J. Bond, Jon E. Keeley
2005, Trends in Ecology and Evolution (20) 387-394
It is difficult to find references to fire in general textbooks on ecology, conservation biology or biogeography, in spite of the fact that large parts of the world burn on a regular basis, and that there is a considerable literature on the ecology of fire and its use for managing...
Turbulence investigation and reproduction for assisting downstream migrating juvenile salmonids, Part II of II: Effects of induced turbulence on behavior of juvenile salmon, 2001-2005 final report
R. Perry, M. Farley, G. Hansen, J. Morse, D. Rondorf
2005, Report
Passage through dams is a major source of mortality of anadromous juvenile salmonids because some populations must negotiate up to eight dams in Columbia and Snake rivers. Dams cause direct mortality when fish pass through turbines, but dams may also cause indirect mortality by altering migration conditions in rivers. Forebays...
Development and analysis of regional curves for streams in the non-urban valley and ridge physiographic province, Maryland, Virginia, and West Virginia
Jefferson N. Keaton, Terence Messinger, Edward J. Doheny
2005, Scientific Investigations Report 2005-5076
Regression relations for bankfull stream characteristics based on drainage area (often called 'regional curves') are used in natural stream channel design to verify field determinations of bankfull discharge and stream channel characteristics. Bankfull stream characteristics were assessed for stream reaches at 41 streamflow-gaging stations in the Valley and Ridge Physiographic...

2005, Open-File Report 2005-1080
The N aquifer is the major source of water in the 5,400-square-mile area of Black Mesa in northeastern Arizona. Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and precipitation of about 6 to 14 inches per year. The monitoring...

Wanda L. Molina-Rivera
2005, Open-File Report 2005-1201
Water-use data were compiled for the 78 municipios of the Commonwealth of Puerto Rico for 2000. Five offstream categories were considered: public-supply water withdrawals, domestic self-supplied water use, industrial self-supplied withdrawals, crop irrigation water use, and thermoelectric power fresh water use. Two additional categories also were considered: power generation instream...
