Jason R. Herrala, Patrick T. Kroboth, Nathan M. Kuntz, Harold L. Schramm Jr.
2014, Transactions of the American Fisheries Society (143) 153-163
The Pallid Sturgeon Scaphirhynchus albus is an endangered riverine sturgeon with historical distribution restricted to the Yellowstone, Missouri, Mississippi, and Atchafalaya rivers. Although not abundant, Pallid Sturgeon in the lower Mississippi River appear to be naturally recruiting, and information about habitat use is important to conserve this species. Thirty-four adult...

Arsenic is perhaps history’s favorite poison, often termed the “King of Poisons” and the “Poison of Kings” and thought to be the demise of fiction’s most famous ill-fated lovers. The toxic nature of arsenic has been known for millennia with the mineral realgar (AsS), originally named “arsenikon” by Theophrastus in...
The environmental geochemistry of Arsenic – An overview
Robert J. Bowell, Charles N. Alpers, Heather E. Jamieson, D. Kirk Nordstrom, Juraj Majzlan
2014, Reviews in Mineralogy and Geochemistry (79) 1-16
Arsenic is one of the most prevalent toxic elements in the environment. The toxicity, mobility, and fate of arsenic in the environment are determined by a complex series of controls dependent on mineralogy, chemical speciation, and biological processes. The element was first described by Theophrastus in 300 B.C. and named...
ARkStorm@Tahoe: Stakeholder perspectives on vulnerabilities and preparedness for an extreme storm event in the greater Lake Tahoe, Reno, and Carson City region
Christine M. Albano, Dale A. Cox, Michael D. Dettinger, Kevin Shaller, Toby L. Welborn, Maureen McCarthy
2014, Report
Atmospheric rivers (ARs) are strongly linked to extreme winter precipitation events in the Western U.S., accounting for 80 percent of extreme floods in the Sierra Nevada and surrounding lowlands. In 2010, the U.S. Geological Survey developed the ARkStorm extreme storm scenario for California to quantify risks from extreme winter storms...
Observations from borehole dilution logging experiments in fractured crystalline rock under variable hydraulic conditions
Philip T. Harte, J. Alton Anderson, John H. Williams
2014, Conference Paper, Symposium on the application of geophysics to engineering and environmental problems 2014
Identifying hydraulically active fractures in low permeability, crystalline-bedrock aquifers requires a variety of geophysical and hydrogeophysical borehole tools and approaches. One such approach is Single Borehole Dilution Tests (SBDT), which in some low flow cases have been shown to provide greater resolution of borehole flow than other logging procedures, such...

Shale hydrocarbon reservoirs: Some influences of tectonics and paleogeography during deposition
Jennifer D Eoff
2014, Book chapter, Geology of the Haynesville gas shale in east Texas and west Louisiana
Continuous hydrocarbon accumulations in shale reservoirs appear to be characterized by common paleotectonic and paleogeographic histories and are limited to specific intervals of geologic time. In addition, most North American self-sourced shale correlates with geologic time periods of calcitic seas and greenhouse conditions and with evolutionary turnover of marine...

2014, Remote Sensing (6) 10306-10334
The increasing competition for water resources requires a better understanding of flows, fluxes, stocks, and the services and benefits related to water consumption. This paper explains how public domain Earth Observation data based on Moderate Resolution Imaging Spectroradiometer (MODIS), Second Generation Meteosat (MSG), Tropical Rainfall Measurement Mission (TRMM) and various...

2014, Conference Paper, Proceedings: ISPRS Technical Commission I Symposium (Volume XL-1)
Over the past decade, great progress has been made to develop national extent land cover mapping products to address natural resource issues. One of the core products of the GAP Program is range-wide species distribution models for nearly 2000 terrestrial vertebrate species in the U.S. We rely on deductive modeling...

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing...
Unique characteristics of the trachea of the juvenile leatherback turtle facilitate feeding, diving and endothermy
John Davenport, T. Todd Jones, Thierry M. Work, George H. Balazs
2014, Journal of Experimental Marine Biology and Ecology (450) 40-46
The adult leatherback turtle Dermochelys coriacea overlaps in body size (300–500 kg) with many marine mammals, yet develops from a 50 g hatchling. Adults can dive deeper than 1200 m and have core body temperatures of 25 °C; hatchlings are near-surface dwellers. Juvenile leatherbacks have rarely been studied; here we...
Impact of climate variability on runoff in the north-central United States
Karen R. Ryberg, Wei Lin, Aldo V. Vecchia
2014, Journal of Hydrologic Engineering (19) 148-158
Large changes in runoff in the north-central United States have occurred during the past century, with larger floods and increases in runoff tending to occur from the 1970s to the present. The attribution of these changes is a subject of much interest. Long-term precipitation, temperature, and streamflow records were used...
The relation between invertebrate drift and two primary controls, discharge and benthic densities, in a large regulated river
Theodore A. Kennedy, Charles B. Yackulic, Wyatt F. Cross, Paul E. Grams, Michael D. Yard, Adam J. Copp
2014, Freshwater Biology (59) 557-572
1. Invertebrate drift is a fundamental process in streams and rivers. Studies from laboratory experiments and small streams have identified numerous extrinsic (e.g. discharge, light intensity, water quality) and intrinsic factors (invertebrate life stage, benthic density, behaviour) that govern invertebrate drift concentrations (# m−3), but the factors that govern invertebrate...

Rodney R. Knight, Jennifer C. Murphy, William J. Wolfe, Charles F. Saylor, Amy K. Wales
2014, Ecohydrology (7) 1262-1280
Ecological limit functions relating streamflow and aquatic ecosystems remain elusive despite decades of research. We investigated functional relationships between species richness and changes in streamflow characteristics at 662 fish sampling sites in the Tennessee River basin. Our approach included the following: (1) a brief summary of relevant literature on...

Pamela R. Garrettson, Robert V. Raftovich, James E. Hines, Guthrie S. Zimmerman
2014, Journal of Wildlife Management (78) 50-57
Estimates of band reporting probabilities are used for managing North American waterfowl to convert band recovery probabilities into harvest probabilities, which are used to set harvest regulations. Band reporting probability is the probability that someone who has shot and retrieved a banded bird will report the band. This probability can...

Roy C. Bartholomay, Brian V. Twining, Peter E. Rose
2014, Groundwater Monitoring & Remediation (34) 79-88
Starting in 2008, a 4-year tracer study was conducted to evaluate ambient changes in groundwater concentrations of a 1,3,6-naphthalene trisulfonate tracer that was added to drill water. Samples were collected under open borehole conditions and after installing a multilevel groundwater monitoring system completed with 11 discrete monitoring zones within dense...
