2017, Fact Sheet 2017-3027
The U.S. Geological Survey (USGS), in partnership with the Idaho Department of Water Resources (IDWR) and Idaho Water Resource Board (IWRB), will construct a numerical groundwater-flow model of the Treasure Valley and surrounding area. Resource managers will use the model to simulate potential anthropogenic and climatic effects on groundwater for...
The effect of urban growth on landscape-scale restoration for a fire-dependent songbird
Bradley A. Pickens, Jeffrey F. Marcus, John P. Carpenter, Scott Anderson, Paul J. Taillie, Jaime A. Collazo
2017, Journal of Environmental Management (191) 105-115
A landscape-scale perspective on restoration ecology has been advocated, but few studies have informed restoration with landscape metrics or addressed broad-scale threats. Threats such as urban growth may affect restoration effectiveness in a landscape context. Here, we studied longleaf pine savanna in the rapidly urbanizing southeastern United States where a...
Disturbance automated reference toolset (DART): Assessing patterns in ecological recovery from energy development on the Colorado Plateau
Travis W. Nauman, Michael C. Duniway, Miguel L. Villarreal, Travis B. Poitras
2017, Science of the Total Environment (584-585) 476-488
A new disturbance automated reference toolset (DART) was developed to monitor human land surface impacts using soil-type and ecological context. DART identifies reference areas with similar soils, topography, and geology; and compares the disturbance condition to the reference area condition using a quantile-based approach based on a satellite vegetation index....

Adam J. Stonewall, Benjamin A. Beal
2017, Scientific Investigations Report 2017-5024
Digital flood-inundation maps were created for a 12.9‑mile reach of Johnson Creek by the U.S. Geological Survey (USGS). The flood-inundation maps depict estimates of water depth and areal extent of flooding from the mouth of Johnson Creek to just upstream of Southeast 174th Avenue in Portland, Oregon. Each flood-inundation...
Monitoring protocols: Options, approaches, implementation, benefits
Jason W. Karl, Jeffrey E. Herrick, David A. Pyke
2017, Book chapter, Monitoring protocol: Options, approaches, implementation, benefits
Monitoring and adaptive management are fundamental concepts to rangeland management across land management agencies and embodied as best management practices for private landowners. Historically, rangeland monitoring was limited to determining impacts or maximizing the potential of specific land uses—typically grazing. Over the past several decades, though, the uses of and...

Jeffrey E. Lovich, Mari Quillman, Brian Zitt, Adam Schroeder, David E. Green, Charles B. Yackulic, Paul Gibbons, Eric Goode
2017, Knowledge and Management of Aquatic Ecosystems (418) 1-11
We documented a significant mortality event affecting a southwestern pond turtle (Actinemys pallida) population living in a lake in southern California, USA. The area around the lake was impacted by a large wildland fire in 2013 that occurred during a protracted drought. As the mortality event was still unfolding, we...
Community disruptions and business costs for distant tsunami evacuations using maximum versus scenario-based zones
Nathan J. Wood, Rick I. Wilson, Jamie L. Ratliff, Jeff Peters, Ed MacMullan, Tessa Krebs, Kimberley Shoaf, Kevin Miller
2017, Natural Hazards (86) 619-643
Well-executed evacuations are key to minimizing loss of life from tsunamis, yet they also disrupt communities and business productivity in the process. Most coastal communities implement evacuations based on a previously delineated maximum-inundation zone that integrates zones from multiple tsunami sources. To support consistent evacuation planning that protects lives but...
Spatial variability of CO2 concentrations and biogeochemistry in the Lower Columbia River
John T. Crawford, David Butman, Luke C. Loken, Philipp Stadler, Catherine Kuhn, Robert G. Striegl
2017, Inland Waters (7) 417-427
Carbon dioxide (CO2) emissions from rivers and other inland waters are thought to be a major component of regional and global carbon cycling. In large managed rivers such as the Columbia River, contemporary ecosystem changes such as damming, nutrient enrichment, and increased water residence times may lead to reduced CO2 concentrations...

Effects of experimental removal of barred owls on population demography of northern spotted owls in Washington and Oregon—2016 progress report
J. David Wiens, Katie M. Dugger, Krista E. Lewicki, David C. Simon
2017, Open-File Report 2017-1040
Evidence indicates that competition with invasive barred owls (Strix varia) is causing rapid declines in populations of northern spotted owls (S. occidentalis caurina), and that the long-term persistence of spotted owls may be in question without additional management intervention. A pilot study in California showed that removal of barred...

2017, Journal of Virology (91)
Introductions of low-pathogenic avian influenza (LPAI) viruses of subtypes H5 and H7 into poultry from wild birds have the potential to mutate to highly pathogenic avian influenza (HPAI) viruses, but such viruses' origins are often unclear. In January 2016, a novel H7N8 HPAI virus caused an outbreak in turkeys in...

2017, Endangered Species Research (33) 281-289
The Deepwater Horizon explosion in April 2010 and subsequent oil spill released 3.19 × 106 barrels (5.07 × 108 L) of MC252 crude oil into important foraging areas of the endangered Kemp’s ridley sea turtle Lepidochelys kempii (Lk) in the northern Gulf of Mexico (GoM). We measured δ13C and δ15N...
Integrated species distribution models: combining presence-background data and site-occupancy data with imperfect detection
Vira Koshkina, Yang Wang, Ascelin Gordon, Robert Dorazio, Matthew White, Lewi Stone
2017, Methods in Ecology and Evolution (8) 420-430
Two main sources of data for species distribution models (SDMs) are site-occupancy (SO) data from planned surveys, and presence-background (PB) data from opportunistic surveys and other sources. SO surveys give high quality data about presences and absences of the species in a particular area. However, due to...
Cloud detection algorithm comparison and validation for operational Landsat data products

2017, Remote Sensing of Environment (194) 379-390
Clouds are a pervasive and unavoidable issue in satellite-borne optical imagery. Accurate, well-documented, and automated cloud detection algorithms are necessary to effectively leverage large collections of remotely sensed data. The Landsat project is uniquely suited for comparative validation of cloud assessment algorithms because the modular architecture of the Landsat ground...
Optimization of a Plaque Neutralization Test (PNT) to identify the exposure history of Pacific Herring to viral hemorrhagic septicemia virus (VHSV)
Lucas Hart, Ashley MacKenzie, Maureen K. Purcell, Rachel L. Thompson, Paul Hershberger
2017, Journal of Aquatic Animal Health (29) 74-82
Methods for a plaque neutralization test (PNT) were optimized for the detection and quantification of viral hemorrhagic septicemia virus (VHSV) neutralizing activity in the plasma of Pacific Herring Clupea pallasii. The PNT was complement dependent, as neutralizing activity was attenuated by heat inactivation; further, neutralizing activity was mostly restored by...
Geomorphic process from topographic form: automating the interpretation of repeat survey data in river valleys
Alan Kasprak, Joshua J. Caster, Sara G. Bangen, Joel B. Sankey
2017, Earth Surface Processes and Landforms (42) 1872-1883
The ability to quantify the processes driving geomorphic change in river valley margins is vital to geomorphologists seeking to understand the relative role of transport mechanisms (e.g. fluvial, aeolian, and hillslope processes) in landscape dynamics. High-resolution, repeat topographic data are becoming readily available to geomorphologists. By contrasting digital elevation models...
Benefits of the destinations, not costs of the journeys, shape partial migration patterns
Charles B. Yackulic, Stephen Blake, Guillaume Bastille-Rousseau
2017, Journal of Animal Ecology (86) 972-982
1. The reasons that lead some animals to seasonally migrate, and others to remain in the same area year-round, are poorly understood. Associations between traits, such as body size, and migration provide clues. For example, larger species and individuals are more likely to migrate.2. One explanation for this size bias...
