2018, Open-File Report 2018-1064
Executive SummaryData from a long-term capture-recapture program were used to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder...
Assessment of dissolved-selenium concentrations and loads in the lower Gunnison River Basin, Colorado, as part of the Selenium Management Program, from 2011 to 2016
Mark F. Henneberg
2018, Scientific Investigations Report 2018-5001
The Gunnison Basin Selenium Management Program implemented a water-quality monitoring network in 2011 in the lower Gunnison River Basin in Colorado. Selenium is a trace element that bioaccumulates in aquatic food chains and can cause reproductive failure, deformities, and other harmful effects. This report presents the percentile values of selenium...

2018, Biological Invasions (20) 2707-2713
The Cuban treefrog, Osteopilus septentrionalis, is native to Cuba, the Bahamas, and the Cayman Islands, and is invasive in areas where it has been introduced and established in the Caribbean as well as Florida. Despite repeated occurrences in several states over many years, it was not believed that Cuban...
Natural hazards in Goma and the surrounding villages, East African Rift System
Charles M. Balagizi, Antoine Kies, Marcellin M. Kasereka, Dario Tedesco, Mathieu M. Yalire, Wendy A. McCausland
2018, Natural Hazards (93) 31-66
The city of Goma and its surrounding villages (Democratic Republic of the Congo, DRC) are among the world’s most densely populated regions strongly affected by volcanic hazards. In 2002, Nyiragongo volcano erupted destroying 10–15% of Goma and forced a mass evacuation of the population. Hence, the ~ 1.5 million inhabitants of Goma and...
Numerical models of pore pressure and stress changes along basement faults due to wastewater injection: Applications to the 2014 Milan, Kansas Earthquake
Elizabeth H. Hearn, Christine Koltermann, Justin R. Rubinstein
2018, Geochemistry, Geophysics, Geosystems (19) 1178-1198
We have developed groundwater flow models to explore the possible relationship between wastewater injection and the 12 November 2014 Mw 4.8 Milan, Kansas earthquake. We calculate pore pressure increases in the uppermost crust using a suite of models in which hydraulic properties of the Arbuckle Formation and the Milan earthquake fault...

Malcolm Scully, John Trowbridge, Christopher R. Sherwood, Katie R. Jones, Peter A. Traykovski
2018, Journal of Geophysical Research C: Oceans (123) 2494-2512
Direct covariance observations of the mean flow Reynolds stress and sonar images of the seafloor collected on a wave‐exposed inner continental shelf demonstrate that the drag exerted by the seabed on the overlying flow is consistent with boundary layer models for wave‐current interaction, provided that the orientation and anisotropy of...
Helping decision makers frame, analyze, and implement decisions
Michael C. Runge, Eve McDonald-Madden
2018, Decision Point Online (104) 12-15
All decisions have the same recognizable elements. Context, objectives, alternatives, consequences, and deliberation. Decision makers and analysts familiar with these elements can quickly see the underlying structure of a decision.There are only a small number of classes of decisions. These classes differ in the cognitive and scientific challenge they present...

2018, Open-File Report 2018-1037
Seismic hazard assessments that are based on a variety of data and the best available science, coupled with rapid synthesis of real-time information from continuous monitoring networks to guide post-earthquake response, form a solid foundation for effective earthquake loss reduction. With this in mind, the Earthquake Hazards Program (EHP) of...

2018, Open-File Report 2018-1059
Executive SummaryThe collection of high-frequency (in other words, “continuous”) water data has been made easier over the years because of advances in technologies to measure, transmit, store, and query large, temporally dense datasets. Commercially available, in-situ sensors and data-collection platforms—together with new techniques for data analysis—provide an opportunity to monitor...
Imaging a crustal low-velocity layer using reflected seismic waves from the 2014 earthquake swarm at Long Valley Caldera, California: The magmatic system roof?
Nori Nakata, David R. Shelly
2018, Geophysical Research Letters (45) 3481-3488
The waveforms generated by the 2014 Long Valley Caldera earthquake swarm recorded at station MLH show clear reflected waves that are often stronger than direct P and S waves. With waveform analyses, we discover that these waves are reflected at the top of a low-velocity body, which may be residual magma...
The Florida manatee (Trichechus manatus latirostris) T cell receptor loci exhibit V subgroup synteny and chain-specific evolution
Breanna Breaux, Margaret Hunter, Maria Paula Cruz-Schneider, Leonardo Sena, Robert K. Bonde, Michael F. Criscitiello
2018, Developmental and Comparative Immunology (85) 71-85
The Florida manatee (Trichechus manatus latirostris) has limited diversity in the immunoglobulin heavy chain. We therefore investigated the antigen receptor loci of the other arm of the adaptive immune system: the T cell receptor. Manatees are the first species from Afrotheria, a basal eutherian superorder, to have an in-depth characterization of...

2018, Biogeosciences (15) 2467-2480
Constraining coral reef metabolism and carbon chemistry dynamics are fundamental for understanding and predicting reef vulnerability to rising coastal CO2 concentrations and decreasing seawater pH. However, few studies exist along reefs occupying densely inhabited shorelines with known input from land-based sources of pollution. The shallow coral reefs off Kahekili, West Maui,...

Proactive Rainbow Trout suppression reduces threat of hybridization in the Upper Snake River Basin
Ryan Kovach, Robert Al-Chokhachy, Tracy Stephens
2018, North American Journal of Fisheries Management (38) 811-819
Preserving remaining nonhybridized populations Cutthroat Trout Oncorhynchus clarkii is a conservation priority often requiring management action. Although proactive programs for Rainbow Trout O. mykiss and hybrid suppression offer a flexible tool, particularly in large interconnected river basins, this management approach is used less frequently than alternatives such as barriers and...

Margaret Hunter, Gaia Meigs-Friend, Jason A. Ferrante, Aristide Takoukam Kamla, Robert Dorazio, Lucy Keith Diagne, Fabia Luna, Janet M. Lanyon, James P. Reid
2018, Endangered Species Research (35) 101-111
Environmental DNA (eDNA) detection is a technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. For eDNA measurement, genetic material shed into the environment is concentrated from water samples and analyzed for the presence of target species. Cytochrome bquantitative PCR and droplet digital PCR...
Urban growth and landscape connectivity threats assessment at Saguaro National Park, Arizona, USA
Ryan Perkl, Laura M. Norman, David Mitchell, Mark R. Feller, Garrett Smith, Natalie R. Wilson
2018, Journal of Land Use Science (13) 102-117
Urban and exurban expansion results in habitat and biodiversity loss globally. We hypothesize that a coupled-model approach could connect urban planning for future cities with landscape ecology to consider wildland habitat connectivity. Our work combines urban growth simulations with models of wildlife corridors to examine how species will be impacted...
