Margaret Hunter, Pam Schofield, Gaia Meigs-Friend, Mary Brown, Jason Ferrante
2019, Conference Paper, Proceedings of the first international snakehead symposium, American Fisheries Society symposium 89
Bullseye Snakehead Channa marulius (Hamilton 1822) was first detected in the southern Florida town of Tamarac in 2000 and has been expanding its geographic range since. Environmental DNA (eDNA) analysis is a newly-developed technique used to noninvasively detect cryptic or low-density species or those that are logistically difficult-to-study. Genetic material...

2019, American Mineralogist (104) 1487-1502
Although REE (lanthanides + Y) mineralization in alkaline silicate systems is commonly accompanied with Zr mineralization worldwide, our understanding of the relationship between Zr and REE mineralization is still incomplete (e.g. Škoda and Novák, 2007; Linnen et al., 2014; Petrella et al., 2014; Möller and Williams-Jones, 2016; Wu et al.,...
Reanalysis of the U.S. Geological Survey Benchmark Glaciers: Long-term insight into climate forcing of glacier mass balance
Shad O’Neel, Christopher J. McNeil, Louis C. Sass, Caitlyn Florentine, Emily Baker, Erich H. Peitzsch, Daniel J McGrath, Andrew G. Fountain, Daniel B. Fagre
2019, Journal of Glaciology 850-866
Mountain glaciers integrate climate processes to provide an unmatched signal of regional climate forcing. However, extracting the climate signal via intercomparison of regional glacier mass balance records can be problematic when methods for extrapolating and calibrating direct glaciological measurements are mixed or inconsistent. To address this problem, we reanalyzed and...
Ensembles of ETAS models provide optimal operational earthquake forecasting during swarms: Insights from the 2015 San Ramon, California swarm
Andrea L. Llenos, Andrew J. Michael
2019, Bulletin of the Seismological Society of America (109) 2145-2158
Earthquake swarms, typically modeled as time-varying changes in background seismicity that are driven by external processes such as fluid flow or aseismic creep, present challenges for operational earthquake forecasting. While the time decay of aftershock sequences can be estimated with the modified Omori law, it is difficult to forecast...

Debris-flow initiation promoted by extension within a slow-moving landslide
Mark E. Reid, Dianne L. Brien
2019, Conference Paper, 7th International Conference on Debris-flow Hazards Mitigation
The dynamics of slow landslide motion can predispose oversteepened and extended slide regions to debris-flow initiation. For more than 20 years, our real-time monitoring, combined with repeat high-precision GPS surveys, of the Cleveland Corral landslide complex, California, USA, reveals that debris flows initiate from slow-moving kinematic elements of this complex....
Linking sedimentation and erosion patterns with reservoir morphology and dam operations during streambed drawdowns in a flood-control reservoir in the Oregon Cascades
Mackenzie K. Keith, Laurel E. Stratton
2019, Conference Paper, Proceedings of SEDHYD 2019
Since water-year (WY) 2011, pool levels at Fall Creek Lake, Oregon, are temporarily lowered to an elevation near historical streambed each fall, creating free-flowing channel conditions that facilitate downstream passage of juvenile spring Chinook salmon. These drawdown operations have also mobilized substantial quantities of predominantly fine (<2 mm) reservoir sediment...

International Organizations and Programs for Wildlife Conservation
John F. Organ, Gonzalo Medina-Vogel, T. Yoshida
2019, Book chapter, International wildlife management: Conservation challenges in a changing world
Historically, private non-governmental entities in the developed world took interest in wildlife in developing nations. Nineteenth and early twentieth century explorers of Africa, Asia, and South America reported fascinating encounters with magnificent species that were previously cryptic or unknown (Robinson et al. 2017). Organizations such as the Royal...
Restoration of Lake Trout in Lake Superior through Interagency Cooperative Management
Michael J. Hansen, Charles R. Bronte
2019, Book chapter, From catastrophe to recovery: stories of fish management success
The lake trout is a keystone species in the Laurentian Great Lakes that supported valuable fisheries throughout the basin. However, lake trout populations declined to near extirpation in nearly all of the lakes because of the combined effects of over-fishing, sea lamprey predation, and habitat degradation. To restore...

Can geologic factors be predictive for distinguishing between productive and non-productive geothermal wells?
Drew L. Siler, Erick R. Burns, James E Faulds
2019, Geothermal Resources Council Transactions (43) 884-901
Geologic data are examined to evaluate whether certain geologic characteristics occur in higher abundance or higher magnitude along production geothermal wells relative to non-productive wells. We perform 3D geologic mapping, 3D stress modeling, and fault-slip modeling to estimate fourteen different geologic factors that are hypothesized to control or correlate with...

Benefits and limitations of installing driving surface aggregate at two federal lands sites
Bethany K. Kunz, Eric H. Chase, Steve M. Bloser, Maureen A. Kestler, Brandon Jutz
2019, Conference Paper
The worldwide network of unpaved roads is estimated to include at least 14 million km (8.7 million miles; 1). Although they are vital for local communities, these roads are expensive to maintain and may cause environmental damage through sediment and dust pollution (e.g., 2). Among aggregate-surfaced roads, locally available materials...

A fuzzy logic approach for estimating recovery factors of miscible CO2-EOR projects in the United States
C. Ozgen Karacan
2019, Journal of Petroleum Science and Engineering (184)
"Recovery factor (RF) is one of the most fundamental parameters that define engineering and economical success of any operational phase in oil and gas production. The effectiveness of the operation, e.g. CO2-EOR (enhanced oil recovery with carbon dioxide injection), is usually defined by multiplying the resultant recovery factor by the...
