Evolution of overpressured and underpressured oil and gas reservoirs, Anadarko Basin of Oklahoma, Texas, and Kansas
Phillip H. Nelson, Nicholas J. Gianoutsos
2011, Open-File Report 2011-1245
Departures of resistivity logs from a normal compaction gradient indicate that overpressure previously extended north of the present-day overpressured zone. These indicators of paleopressure, which are strongest in the deep basin, are mapped to the Kansas-Oklahoma border in shales of Desmoinesian age. The broad area of paleopressure has contracted to...
Range-wide assessment of livestock grazing across the sagebrush biome
Kari E. Veblen, David A. Pyke, Christopher A. Jones, Michael L. Casazza, Timothy J. Assal, Melissa A. Farinha
2011, Open-File Report 2011-1263
Domestic livestock grazing occurs in virtually all sagebrush habitats and is a prominent disturbance factor. By affecting habitat condition and trend, grazing influences the resources required by, and thus, the distribution and abundance of sagebrush-obligate wildlife species (for example, sage-grouse Centrocercus spp.). Yet, the risks that livestock grazing may pose...

Michael C. Hayes, Reginald R. Reisenbichler, Stephen P. Rubin, Lisa A. Wetzel, Anne R. Marshall
2011, Transactions of the American Fisheries Society (140) 1305-1316
Differential survival and growth were tested in Chinook salmon Oncorhynchus tshawytscha expressing two common alleles, *–100 and *–260, at the superoxide dismutase locus (sSOD-1*). These tests were necessary to support separate studies in which the two alleles were used as genetic marks under the assumption of mark neutrality. Heterozygous adults...
Flood-frequency analyses from paleoflood investigations for Spring, Rapid, Boxelder, and Elk Creeks, Black Hills, western South Dakota
Tessa M. Harden, Jim E. O'Connor, Daniel G. Driscoll, John F. Stamm
2011, Scientific Investigations Report 2011-5131
Flood-frequency analyses for the Black Hills area are important because of severe flooding of June 9-10, 1972, that was caused by a large mesoscale convective system and caused at least 238 deaths. Many 1972 peak flows are high outliers (by factors of 10 or more) in observed records that date...

Occupancy and abundance of wintering birds in a dynamic agricultural landscape
Mark W. Miller, Elise V. Pearlstine, Robert M. Dorazio, Frank J. Mazzotti
2011, Journal of Wildlife Management (75) 836-847
Assessing wildlife management action requires monitoring populations, and abundance often is the parameter monitored. Recent methodological advances have enabled estimation of mean abundance within a habitat using presence–absence or count data obtained via repeated visits to a sample of sites. These methods assume populations are closed and intuitively assume habitats...

John E. Mcdonald Jr., Stephen DeStefano, Christopher Gaughan, Michael Mayer, William A. Woytek, Sonja Christensen, Todd K. Fuller
2011, Wildlife Society Bulletin (35) 209-219
We monitored 142 radiocollared adult (≥1.0 yr old) white-tailed deer (Odocoileus virginianus) in 3 study areas of Massachusetts, USA, to estimate annual survival and mortality due to legal hunting. We then applied these rates to deer harvest information to estimate deer population trends over time, and compared these to trends...

Observations of debris flows at Chalk Cliffs, Colorado, USA: Part 1, in-situ measurements of flow dynamics, tracer particle movement and video imagery from the summer of 2009
Scott W. McCoy, Jeffrey A. Coe, Jason W. Kean, Greg E. Tucker, Dennis M. Staley, Thad A. Wasklewicz
2011, Italian Journal of Engineering Geology and Environment 715-726
Debris flows initiated by surface-water runoff during short duration, moderate- to high-intensity rainfall are common in steep, rocky, and sparsely vegetated terrain. Yet large uncertainties remain about the potential for a flow to grow through entrainment of loose debris, which make formulation of accurate mechanical models of debris-flow routing difficult....
