2015, Journal of Wildlife Management (79) 1264-1276
More than 600,000 ha of mine land have been reclaimed in the eastern United States, providing large contiguous tracts of early successional vegetation that can be managed for northern bobwhite (Colinus virginianus). However, habitat quality on reclaimed mine land can be limited by extensive coverage of non-native invasive species, which are...

2015, Natural Resource Data Series 2015-804
With the translocation and release of 90 fishers (Pekania pennanti) from British Columbia to Olympic National Park during 2008–2010, the National Park Service and Washington Department of Fish and Wildlife accomplished the first phase of fisher restoration in Washington State. Beginning in 2013, we initiated a new research project to...
The influence of logjams on largemouth bass (Micropterus salmoides) concentrations on the lower Roanoke River, a large sand-bed river
Edward R. Schenk, Jeremy W. McCargo, Bertrand Moulin, Cliff R. Hupp, Jean M. Richter
2015, River Research and Applications (31) 704-711
This study examines the relation between logjams and largemouth bass (Micropterus salmoides) on the alluvial sand-bed lower Roanoke River. Disparate data sets from previous bank erosion, fisheries, and large wood studies were used to compare the distribution of largemouth bass with logjam frequency. Logjams are related to the frequency of...
Dynamic models of an earthquake and tsunami offshore Ventura, California
Kenny J. Ryan, Eric L. Geist, Michael Barall, David D. Oglesby
2015, Geophysical Research Letters (42) 6599-6606
The Ventura basin in Southern California includes coastal dip-slip faults that can likely produce earthquakes of magnitude 7 or greater and significant local tsunamis. We construct a 3-D dynamic rupture model of an earthquake on the Pitas Point and Lower Red Mountain faults to model low-frequency ground motion and the...
Sensitivity of intermittent streams to climate variations in the USA
Ken Eng, David M. Wolock, Mike Dettinger
2015, River Research and Applications (32) 885-895
There is a great deal of interest in the literature on streamflow changes caused by climate change because of the potential negative effects on aquatic biota and water supplies. Most previous studies have primarily focused on perennial streams, and there have been only a few studies examining the effect of...

Jennifer L. Stenglein, Timothy R. Van Deelen, Adrian P. Wydeven, David J. Mladenoff, Jane E. Wiedenhoft, Nancy K. Businga, Julia A. Langenberg, Nancy J. Thomas, Dennis M. Heisey
2015, Journal of Wildlife Management (79) 1173-1184
We developed models and provide computer code to make carcass recovery data more useful to wildlife managers. With these tools, wildlife managers can understand the spatial, temporal (e.g., across time periods, seasons), and demographic patterns in mortality causes from carcass recovery datasets. From datasets of radio-collared and non-collared carcasses, managers...

2015, Scientific Investigations Report 2015-5093
The North Platte Natural Resources District (NPNRD) has been actively collecting data and studying groundwater resources because of concerns about the future availability of the highly inter-connected surface-water and groundwater resources. This report, prepared by the U.S. Geological Survey in cooperation with the North Platte Natural Resources District, describes a...
Organic and inorganic composition and microbiology of produced waters from Pennsylvania shale gas wells
Denise M. Akob, Isabelle M. Cozzarelli, Darren S. Dunlap, Elisabeth L. Rowan, Michelle M. Lorah
2015, Applied Geochemistry (60) 116-125
Hydraulically fractured shales are becoming an increasingly important source of natural gas production in the United States. This process has been known to create up to 420 gallons of produced water (PW) per day, but the volume varies depending on the formation, and the characteristics of individual hydraulic fracture. PW...
Origins of geothermal gases at Yellowstone
Jacob B. Lowenstern, Deborah Bergfeld, William C. Evans, Andrew G. Hunt
2015, Journal of Volcanology and Geothermal Research (302) 87-101
Gas emissions at the Yellowstone Plateau Volcanic Field (YPVF) reflect open-system mixing of gas species originating from diverse rock types, magmas, and crustal fluids, all combined in varying proportions at different thermal areas. Gases are not necessarily in chemical equilibrium with the waters through which they vent, especially in acid...

A-type granites, as originally defined by Loiselle and Wones (1979),...
A floral survey of cliff habitats along Bull Run at Manassas National Battlefield Park, Virginia, 2014
Esther D. Stroh, Matthew A. Struckhoff, Keith W. Grabner
2015, Data Series 940
Isolated patches of native vegetation in human-modified landscapes are important reservoirs of biological diversity because they may be the only places in which rare or native species can persist. Manassas National Battlefield Park, Virginia, is an island embedded in a matrix of intensively modified lands; it is becoming increasingly isolated...

Evaluation of autonomous recording units for detecting 3 species of secretive marsh birds
Anna M. Sidie-Slettehahl, Kent C. Jensen, Rex R. Johnson, Todd W. Arnold, Jane E. Austin, Joshua D. Stafford
2015, Wildlife Society Bulletin (39) 626-634
Population status and habitat use of yellow rails (Coturnicops noveboracensis), Nelson's sparrows (Ammodramus nelsoni), and Le Conte's sparrows (A. leconteii) are poorly known, so standardized surveys of these species are needed to inform conservation planning and management. A protocol for monitoring secretive marsh birds exists; however, these species regularly call...

Dianna M. Crilley, Jake W. Collison
2015, Scientific Investigations Report 2015-5060
Eastern Bernalillo County, New Mexico, is a historically rural area that in recent years has experienced an increase in population and in the construction of new housing units, most of which are not connected to a centralized wastewater treatment system. Increasing water use has raised concerns about the effect of...
Sources of high-chloride water and managed aquifer recharge in an alluvial aquifer in California, USA
David O’Leary, John A. Izbicki, Loren F. Metzger
2015, Hydrogeology Journal (23) 1515-1533
As a result of pumping in excess of recharge, water levels in alluvial aquifers within the Eastern San Joaquin Groundwater Subbasin, 130 km east of San Francisco (California, USA), declined below sea level in the early 1950s and have remained so to the present. Chloride concentrations in some wells increased...
Mapping surficial minerals at high latitudes: The USGS 2014 imaging spectrometer data collection in Alaska
Raymond F. Kokaly, Todd M. Hoefen, Garth Graham, Karen Kelly, Michaela Johnson, Bernard Hubbard, Richard Goldfarb
2015, Conference Paper
Passive optical remote sensing of high latitude regions faces many challenges including a short acquisition season and poor illumination due to low solar elevation. Additional complications are encountered in the identification of surface minerals for mineral resource characterization because minerals of interest commonly are exposed on steep terrain, further challenging...

Charles E. Heywood, John K. Lovelace, Jason M. Griffith
2015, Scientific Investigations Report 2015-5083
Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. The 10 aquifers beneath the Baton Rouge area, which includes East and West Baton Rouge Parishes, Pointe Coupee Parish, and East and West Feliciana Parishes, provided about 184.3 million gallons per day (Mgal/d) for public supply...

A long-term earthquake rate model for the central and eastern United States from smoothed seismicity
Morgan P. Moschetti
2015, Bulletin of the Seismological Society of America (6) 2928-2941
I present a long-term earthquake rate model for the central and eastern United States from adaptive smoothed seismicity. By employing pseudoprospective likelihood testing (L-test), I examined the effects of fixed and adaptive smoothing methods and the effects of catalog duration and composition on the ability of the models to forecast...
