Miguel L. Villarreal, Leila Gass, Laura Norman, Joel B. Sankeya, Cynthia S.A. Wallace, Dennis McMacken, Jack L. Childs, Roy E. Petrakis
2012, Conference Paper, RMRS-P-67
Between 2001 and 2009, the Borderlands Jaguar Detection Project deployed 174 camera traps in the mountains of southern Arizona to record jaguar activity. In addition to jaguars, the motion-activated cameras, placed along known wildlife travel routes, recorded occurrences of ~ 20 other animal species. We examined temporal relationships of white-tailed...

Jonathan A. Warrick, Kurt J. Rosenberger, Angela Lam, Joanne C. T. Ferreira, Ian M. Miller, Meg Rippy, Jan Svejkovsky, Neomi Mustain
2012, Open-File Report 2012-1083
Coastal restoration and management must address the presence, use, and transportation of fine sediment, yet little information exists on the patterns and/or processes of fine-sediment transport and deposition for these systems. To fill this information gap, a number of State of California, Federal, and private industry partners developed the Tijuana...

The U.S. Geological Survey, in cooperation with the National Park Service and Southern Nevada Water Authority, collected near-continuous depth-dependent water-quality data at Lake Mead, Arizona and Nevada, as part of a multi-agency monitoring network maintained to provide resource managers with basic data and to gain a better understanding of the...
A framework for inference about carnivore density from unstructured spatial sampling of scat using detector dogs
Craig M. Thompson, J. Andrew Royle, James D. Garner
2012, Journal of Wildlife Management (76) 863-871
Wildlife management often hinges upon an accurate assessment of population density. Although undeniably useful, many of the traditional approaches to density estimation such as visual counts, livetrapping, or mark–recapture suffer from a suite of methodological and analytical weaknesses. Rare, secretive, or highly mobile species exacerbate these problems through the reality...

Daniel Dzurisin, Charles W. Wicks, Michael P. Poland
2012, Professional Paper 1788
Modern geodetic studies of the Yellowstone caldera, Wyoming, and its extraordinary tectonic, magmatic, and hydrothermal systems date from an initial leveling survey done throughout Yellowstone National Park in 1923 by the U.S. Coast and Geodetic Survey. A repeat park-wide survey by the U.S. Geological Survey (USGS) and the University of...
An annotated bibliography for lamprey habitat in the White Salmon River, Washington
M. Brady Allen
2012, Open-File Report 2012-1086
The October 2011 decommissioning of Condit Dam on the White Salmon River at river kilometer (rkm) 5.3 removed a significant fish passage barrier from the White Salmon River basin for the first time in nearly a century. This affords an opportunity to regain a potentially important drainage basin for Pacific...
Stability of infinite slopes under transient partially saturated seepage conditions
Jonathan W. Godt, Başak Şener-Kaya, Ning Lu, Rex L. Baum
2012, Water Resources Research (48) 1-14
Prediction of the location and timing of rainfall‐induced shallow landslides is desired by organizations responsible for hazard management and warnings. However, hydrologic and mechanical processes in the vadose zone complicate such predictions. Infiltrating rainfall must typically pass through an unsaturated layer before reaching the irregular and usually discontinuous shallow water...

Christine Ribic, Seba B. Sheavly, David J. Rugg, Eric S. Erdmann
2012, Marine Pollution Bulletin (64) 944-1004
We assessed amounts, composition, and trends of marine debris for the U.S. Pacific Coast and Hawai’i using National Marine Debris Monitoring Program data. Hawai’i had the highest debris loads; the North Pacific Coast region had the lowest debris loads. The Southern California Bight region had the highest land-based debris loads....
Timing and proximate causes of mortality in wild bird populations: testing Ashmole’s hypothesis
Daniel C. Barton, Thomas E. Martin
2012, Thesis, Ecological causes of life history variation tested by meta-analysis, comparison, and experimental approaches
Fecundity in birds is widely recognized to increase with latitude across diverse phylogenetic groups and regions, yet the causes of this variation remain enigmatic. Ashmole’s hypothesis is one of the most broadly accepted explanations for this pattern. This hypothesis suggests that increasing seasonality leads to increasing overwinter mortality due to...

LiDAR and field observations of slip distribution for the most recent surface ruptures along the central San Jacinto fault
J.B. Salisbury, T.K. Rockwell, T.J. Middleton, Kenneth W. Hudnut
2012, Bulletin of the Seismological Society of America (102) 598-619
We measured offsets on tectonically displaced geomorphic features along 80 km of the Clark strand of the San Jacinto fault (SJF) to estimate slip‐per‐event for the past several surface ruptures. We identify 168 offset features from which we make over 490 measurements using B4 light detection and ranging (LiDAR) imagery and...

David T. Soong, Crystal D. Prater, Teresa M. Halfar, Loren A. Wobig
2012, Data Series 668
Manning's roughness coefficients for 43 natural and constructed streams in Illinois are reported and displayed on a U.S. Geological Survey Web site. At a majority of the sites, discharge and stage were measured, and corresponding Manning's coefficients—the n-values—were determined at more than one river discharge. The n-values discussed in this...
