Response of selenium concentrations in groundwater to seasonal canal leakage, lower Gunnison River Basin, Colorado, 2013
J.I. Linard, P.B. McMahon, L. R. Arnold, J.C. Thomas
2017, Scientific Investigations Report 2016-5047
Selenium is a water-quality concern in the lower Gunnison River Basin because irrigation water interacting with seleniferous soils derived from the Mancos Shale Formation has mobilized selenium and increased its concentrations in surface water. Understanding the occurrence of elevated selenium concentrations in groundwater is necessary because groundwater discharge is an...
Salinity influences on aboveground and belowground net primary productivity in tidal wetlands
Kathryn N. Pierfelice, B. Graeme Lockaby, Ken W. Krauss, William H. Conner, Gregory E. Noe, Matthew C. Ricker
2017, Journal of Hydrologic Engineering (22)
Tidal freshwater wetlands are one of the most vulnerable ecosystems to climate change and rising sea levels. However salinification within these systems is poorly understood, therefore, productivity (litterfall, woody biomass, and fine roots) were investigated on three forested tidal wetlands [(1) freshwater, (2) moderately saline, and (3) heavily salt-impacted] and a marsh along...
Biological response to climate change in the Arctic Ocean: The view from the past
Thomas M. Cronin, Matthew A. Cronin
2017, arktos (1)
The Arctic Ocean is undergoing rapid climatic changes including higher ocean temperatures, reduced sea ice, glacier and Greenland Ice Sheet melting, greater marine productivity, and altered carbon cycling. Until recently, the relationship between climate and Arctic biological systems was poorly known, but this has changed substantially...

Mark D. Kozar, Kurt J. McCoy, James Q. Britton, B.M. Blake Jr.
2017, Report
The Pocahontas No. 3 coal seam in southern West Virginia has been extensively mined by underground methods since the 1880’s. An extensive network of abandoned mine entries in the Pocahontas No. 3 has since filled with good-quality water, which is pumped from wells or springs discharging from mine portals (adits),...

Micah Hahn, Catherine S. Jarnevich, Andrew J. Monaghan, Rebecca J. Eisen
2016, Journal of Medical Entomology (53) 1176-1191
In addition to serving as vectors of several other human pathogens, the black-legged tick, Ixodes scapularis Say, and western black-legged tick, Ixodes pacificus Cooley and Kohls, are the primary vectors of the spirochete (Borrelia burgdorferi ) that causes Lyme disease, the most common vector-borne disease in the United States. Over...

Background: Bladder cancer mortality rates have been elevated in northern New England for at least five decades. Incidence rates in Maine, New Hampshire, and Vermont are about 20% higher than the United States overall. We explored reasons for this excess, focusing on arsenic in drinking water from private wells, which...

Richard A. Erickson, Wayne E. Thogmartin, James E. Diffendorfer, Robin E. Russell, Jennifer A. Szymanski
2016, PeerJ 1-19
Wind energy generation holds the potential to adversely affect wildlife populations. Species-wide effects are difficult to study and few, if any, studies examine effects of wind energy generation on any species across its entire range. One species that may be affected by wind energy generation is the endangered Indiana bat...
Impacts of short-rotation early-growing season prescribed fire on a ground nesting bird in the central hardwoods region of North America
H. Tyler Pittman, David G. Krementz
2016, PLoS ONE (11) 1-14
Landscape-scale short-rotation early-growing season prescribed fire, hereafter prescribed fire, in upland hardwood forests represents a recent shift in management strategies across eastern upland forests. Not only does this strategy depart from dormant season to growing season prescriptions, but the strategy also moves from stand-scale to landscape-scale implementation (>1,000 ha). This...

2016, Seismological Research Letters (87) 1327-1341
The U.S. Geological Survey (USGS) has produced a one‐year (2016) probabilistic seismic‐hazard assessment for the central and eastern United States (CEUS) that includes contributions from both induced and natural earthquakes that are constructed with probabilistic methods using alternative data and inputs. This hazard assessment builds on our 2016 final model...
Thermal mapping of a pahoehoe lava flow, Kilauea Volcano
Matthew R. Patrick, Tim R. Orr, Gary B. Fisher, Frank A. Trusdell, James P. Kauahikaua
2016, Journal of Volcanology and Geothermal Research (332) 71-87
Pāhoehoe lava flows are a major component of Hawaiian eruptive activity, and an important part of basaltic volcanism worldwide. In recent years, pāhoehoe lava has destroyed homes and threatened parts of Hawai‘i with inundation and disruption. In this study, we use oblique helicopter-borne thermal images to create high...
