Scott Christenson, Andrew G. Hunt, David L. Parkhurst
2009, Scientific Investigations Report 2009-5036
A geochemical reconnaissance investigation of the Arbuckle-Simpson aquifer in south-central Oklahoma was initiated in 2004 to characterize the ground-water quality at an aquifer scale, to describe the chemical evolution of ground water as it flows from recharge areas to discharge in wells and springs, and to determine the residence time...
The Farm Process Version 2 (FMP2) for MODFLOW-2005 - Modifications and Upgrades to FMP1
Wolfgang Schmid, R. T. Hanson
2009, Techniques and Methods 6-A32
The ability to dynamically simulate the integrated supply-and-demand components of irrigated agricultural is needed to thoroughly understand the interrelation between surface water and groundwater flow in areas where the water-use by vegetation is an important component of the water budget. To meet this need, the computer program Farm Process (FMP1)...
Determining the efficacy of microsatellite DNA-based mixed-stock analysis of Lake Michigan’s lake whitefish commercial fishery
Justin A. VanDeHey, Brian L. Sloss, Paul J. Peeters, Trent M. Sutton
2009, Journal of Great Lakes Research (36) 52-58
Management of commercially exploited fish should be conducted at the stock level. If a mixed stock fishery exists, a comprehensive mixed stock analysis is required for stock-based management. The lake whitefish Coregonus clupeaformis comprises the primary commercial fishery across the Great Lakes. Recent research resolved that six genetic stocks of lake whitefish...

2009, Open-File Report 2009-1183
We used capture-recapture data to assess population dynamics of endangered Lost River suckers (Deltistes luxatus) and shortnose suckers (Chasmistes brevirostris) in Upper Klamath Lake, Oregon. The Cormack-Jolly-Seber method was used to estimate apparent survival probabilities, and a temporal symmetry model was used to estimate annual seniority probabilities. Information theoretic modeling...
The crowbar chronicles and other tales
Susan E. Hough
2009, Seismological Research Letters (80) 615-616
The analysis of historical earthquakes often relies heavily on archival accounts describing the effects of shaking on structures and people. Newspaper articles are among the most common, useful, and easily found sources of information. Dramatic earthquake effects are almost certain to have made the news during historic times; the challenge...

Charles C. Schwartz, Shannon Podruzny, Steven L. Cain, Steve Cherry
2009, Journal of Wildlife Management (73) 1174-1183
Global Positioning System (GPS) telemetry is a prevalent tool now used in the study of large mammals. Global Positioning Systems either store the data on board the collar or contain a remote-transfer system that allows for data recovery at more frequent intervals. Spread spectrum (S–S) technology is a new mode...

Craig G. Lorimer, Daniel J. Porter, Mary Ann Madej, John D. Stuart, Stephen D. Veirs Jr., Steven P. Norman, Kevin L. O’Hara, William J. Libby
2009, Forest Ecology and Management (258) 1038-1054
Coast redwood (Sequoia sempervirens), a western North American conifer of ancient lineage, has a paradoxical combination of late-successional characteristics and strong adaptations to disturbance. Despite its shade tolerance and heavy dominance of the canopy on many sites, redwood saplings are uncommon in upland old-growth stands. Information needed to ensure the...

2009, Wetlands (29) 875-883
California’s Tulare Lake Basin (TLB) is one of the most important waterbird areas in North America even though most wetlands there have been converted to cropland. To guide management programs promoting waterbird beneficial agriculture, which includes flooding fields between growing periods, we measured emergence rates of insects, an important waterbird...

Hydrologic Setting and Conceptual Hydrologic Model of the Walker River Basin, West-Central Nevada
Thomas J. Lopes, Kip K. Allander
2009, Scientific Investigations Report 2009-5155
The Walker River is the main source of inflow to Walker Lake, a closed-basin lake in west-central Nevada. Between 1882 and 2008, agricultural diversions resulted in a lake-level decline of more than 150 feet and storage loss of 7,400,000 acre-ft. Evaporative concentration increased dissolved solids from 2,500 to 17,000 milligrams...
