Jessica L. Brubaker, Natalie K. Karouna-Renier, Yu Chen, Kathryn Jenko, Daniel T. Sprague, Paula F.P. Henry
2011, Molecular Ecology Resources (11) 415-417
Polymerase chain reaction (PCR)-based methods to determine the sex of birds are well established and have seen few modifications since they were first introduced in the 1990s. Although these methods allowed for sex determination in species that were previously difficult to analyse, they were not conducive to high-throughput analysis because...

Patrick G.R. Jodice, Lisa C. Wickliffe, Elena B. Sachs
2011, Marine Biology (158) 2289-2298
Shrimp trawling is common throughout the southeastern and Gulf of Mexico coasts of the USA and is the primary contributor to fisheries discards in these regions. Tens of thousands of nearshore seabirds nest near shrimp trawling grounds in the USA, but to date, there has been no assessment of the...
Mine wastes and human health
Geoffrey S. Plumlee, Suzette A. Morman
2011, Elements (7) 399-404
Historical mining and mineral processing have been linked definitively to health problems resulting from occupational and environmental exposures to mine wastes. Modern mining and processing methods, when properly designed and implemented, prevent or greatly reduce potential environmental health impacts. However, particularly in developing countries, there are examples of health problems...

Craig M. Ellsworth, Scott P. VanderKooi
2011, Open-File Report 2011-1147
The Chiloquin Dam was located at river kilometer (rkm) 1.3 on the Sprague River near the town of Chiloquin, Oregon. The dam was identified as a barrier that potentially inhibited or prevented the upstream spawning migrations and other movements of endangered Lost River suckers (Deltistes luxatus), shortnose suckers (Chasmistes brevirostris),...

Julia L. Barringer, Zoltan Szabo, Jennifer L. Bonin, Craig K. McGee
2011, Scientific Investigations Report 2011-5017
Arsenic (As) concentrations in the waters of Raccoon Creek in southern New Jersey commonly exceed the State\'s Surface Water Quality Standard (SWQS) for freshwater of 0.017 microgram per liter (mu or ug/L). In order to assess contributions of As from residential runoff to the creek, samples of runoff water were...
A geospatial approach to identify water quality issues for National Wildlife Refuges in Oregon and Washington
Jo Ellen Hinck, Kimberly Chojnacki, Susan E. Finger, Greg Linder, Kevin Kilbride
2011, Journal of Fish and Wildlife Management (2) 12-21
Many National Wildlife Refuges (Refuges) have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. Competing duties limit the time available for Refuge staff to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until...
Observations of mass fractionation of noble gases in synthetic methane hydrate
Andrew G. Hunt, John W. Pohlman, Laura A. Stern, Carolyn D. Ruppel, Richard J. Moscati, Gary P. Landis, John C. Pinkston
2011, Conference Paper
As a consequence of contemporary or longer term (since 15 ka) climate warming, gas hydrates in some settings are presently dissociating and releasing methane and other gases to the oceanatmosphere system. A key challenge in assessing the susceptibility of gas hydrates to warming climate is the lack of a technique...
A two-phase debris-flow model that includes coupled evolution of volume fractions, granular dilatancy, and pore-fluid pressure
David L. George, Richard M. Iverson
2011, Conference Paper, Debris-flow hazards : mitigation, mechanics, prediction, and assessment : proceedings of 5th international conference : Padua, Italy, 14-17 June 2011
Pore-fluid pressure plays a crucial role in debris flows because it counteracts normal stresses at grain contacts and thereby reduces intergranular friction. Pore-pressure feedback accompanying debris deformation is particularly important during the onset of debrisflow motion, when it can dramatically influence the balance of forces governing downslope acceleration. We consider...

Simulation of groundwater flow in a volatile organic compound-contaminated area near Bethpage, Nassau County, New York: A discussion of modeling considerations
Paul E. Misut
2011, Open-File Report 2011-1128
The 2010 Bethpage groundwater-flow model (ARCADIS, 2010) was based on a steady state assumption. Although it is widely acknowledged that significant water-level changes have occurred in the past, the reviewed model does not represent changing water levels. The steady state approach limits the effectiveness of the following: 1. identification of sources...
