Tree sampling as a method to assess vapor intrusion potential at a site characterized by VOC-contaminated groundwater and soil
Jordan L. Wilson, Matthew A. Limmer, V.A. Samaranayake, John G. Schumacher, Joel G. Burken
2017, Environmental Science & Technology (51) 10369-10378
Vapor intrusion (VI) by volatile organic compounds (VOCs) in the built environment presents a threat to human health. Traditional VI assessments are often time-, cost-, and labor-intensive; whereas traditional subsurface methods sample a relatively small volume in the subsurface and are difficult to collect within and near structures. Trees could...

Joseph D. Ayotte, Laura Medalie, Sharon L. Qi, Lorraine C. Backer, Bernard T. Nolan
2017, Environmental Science & Technology (51) 12443-12454
Arsenic concentrations from 20 450 domestic wells in the U.S. were used to develop a logistic regression model of the probability of having arsenic >10 μg/L (“high arsenic”), which is presented at the county, state, and national scales. Variables representing geologic sources, geochemical, hydrologic, and physical features were among the significant...
Basis function models for animal movement
Mevin Hooten, Devin S. Johnson
2017, Journal of the American Statistical Association (112) 578-589
Advances in satellite-based data collection techniques have served as a catalyst for new statistical methodology to analyze these data. In wildlife ecological studies, satellite-based data and methodology have provided a wealth of information about animal space use and the investigation of individual-based animal–environment relationships. With the technology for data collection...

Potential for spatial displacement of Cook Inlet beluga whales by anthropogenic noise in critical habitat
Robert J. Small, Brian M. Brost, Mevin Hooten, Manuel Castellote, Jeffrey Mondragon
2017, Endangered Species Research (32) 43-57
The population of beluga whales in Cook Inlet, Alaska, USA, declined by nearly half in the mid-1990s, primarily from an unsustainable harvest, and was listed as endangered in 2008. In 2014, abundance was ~340 whales, and the population trend during 1999-2014 was -1.3% yr-1. Cook Inlet beluga whales are...

2017, Scientific Investigations Report 2017-5113
The Sauk River is a federally designated Wild and Scenic River that drains a relatively undisturbed landscape along the western slope of the North Cascade Mountain Range, Washington, which includes the glaciated volcano, Glacier Peak. Naturally high sediment loads characteristic of basins draining volcanoes like Glacier Peak make the...
Remote sensing for wetland mapping and historical change detection at the Nisqually River Delta
Laurel Ballanti, Kristin B. Byrd, Isa Woo, Christopher Ellings
2017, Sustainability (9) 1-32
Coastal wetlands are important ecosystems for carbon storage and coastal resilience to climate change and sea-level rise. As such, changes in wetland habitat types can also impact ecosystem functions. Our goal was to quantify historical vegetation change within the Nisqually River watershed relevant to carbon storage, wildlife habitat, and wetland...
Swimming behaviour and ascent paths of brook trout in a corrugated culvert
Elsa Goerig, Normand E. Bergeron, Theodore R. Castro-Santos
2017, River Research and Applications (33) 1463-1471
Culverts may restrict fish movements under some hydraulic conditions such as shallow flow depths or high velocities. Although swimming capacity imposes limits to passage performance, behaviour also plays an important role in the ability of fish to overcome velocity barriers. Corrugated metal culverts are characterized by unsteady flow and existence...
Differences in human versus lightning fires between urban and rural areas of the boreal forest in interior Alaska
Monika Calef, Anna Varvak, A. David McGuire
2017, Forests (8)
In western North America, the carbon-rich boreal forest is experiencing warmer temperatures, drier conditions and larger and more frequent wildfires. However, the fire regime is also affected by direct human activities through suppression, ignition, and land use changes. Models are important predictive tools for understanding future conditions but they are...
Organic chemical characterization and mass balance of a hydraulically fractured well: From fracturing fluid to produced water over 405 days
James Rosenblum, E. Michael Thurman, Imma Ferrer, George R. Aiken, Karl G. Linden
2017, Environmental Science & Technology (51) 14006-14015
A long-term field study (405 days) of a hydraulically fractured well from the Niobrara Formation in the Denver-Julesburg Basin was completed. Characterization of organic chemicals used in hydraulic fracturing and their changes through time, from the preinjected fracturing fluid to the produced water, was conducted. The characterization consisted of a...

Harold L. Schramm Jr.
2017, Fisheries Magazine (42) 574-585
The Mississippi River is a multijurisdictional and multiuse resource that has been variously altered and is foremost managed for navigation and flood control throughout much of its 3,734‐km passage from its origin at Lake Itasca, Minnesota, to its outlet at the Gulf of Mexico. Despite alterations summarized herein, the native...

The response of soil and stream chemistry to decreases in acid deposition in the Catskill Mountains, New York, USA
Michael McHale, Douglas A. Burns, Jason Siemion, Michael R. Antidormi
2017, Environmental Pollution (229) 607-620
The Catskill Mountains have been adversely impacted by decades of acid deposition, however, since the early 1990s, levels have decreased sharply as a result of decreases in emissions of sulfur dioxide and nitrogen oxides. This study examines trends in acid deposition, stream-water chemistry, and soil chemistry in the southeastern Catskill...

2017, Book chapter, Methods for monitoring tiger and prey populations
Capture-recapture can be viewed as an animal survey method in which the count statistic is the total number of animals caught, and the associated detection probability is the probability of capture....
Rapid exhumation of Cretaceous arc-rocks along the Blue Mountains restraining bend of the Enriquillo-Plantain Garden fault, Jamaica, using thermochronometry from multiple closure systems
William J. Cochran, James A. Spotila, Philip S. Prince, Ryan J. McAleer
2017, Tectonophysics (721) 292-309
The effect of rapid erosion on kinematic partitioning along transpressional plate margins is not well understood, particularly in highly erosive climates. The Blue Mountains restraining bend (BMRB) of eastern Jamaica, bound to the south by the left-lateral Enriquillo-Plantain Garden fault (EPGF), offers an opportunity to test the effects of highly...
Loss of ecosystem services due to chronic pollution of forests and surface waters in the Adirondack region (USA)
Colin M. Beier, Jesse Caputo, Gregory B. Lawrence, Timothy J. Sullivan
2017, Journal of Environmental Management (191) 19-27
Sustaining recent progress in mitigating acid pollution could require lower emissions caps that will give rise to real or perceived tradeoffs between healthy ecosystems and inexpensive energy. Because most impacts of acid rain affect ecosystem functions that are poorly understood by policy-makers and the public, an ecosystem services (ES) framework...
Survival, movement, and distribution of juvenile Burbot in a tributary of the Kootenai River
Zachary S. Beard, Michael C. Quist, Ryan S. Hardy, Tyler J. Ross
2017, North American Journal of Fisheries Management (37) 1274-1288
Burbot Lota lota in the lower Kootenai River, Idaho, have been the focus of extensive conservation efforts, particularly the release of hatchery-reared juvenile Burbot into small tributaries. The Idaho Department of Fish and Game installed a fixed PIT antenna on Deep Creek, a tributary of the Kootenai River, to evaluate movement of...

Imants Kavalieris, Bat-Erdene Khashgerel, Leah E. Morgan, Alexander Undrakhtamir, Adiya Borohul
2017, Economic Geology (112) 1033-1053
The Early to Middle Triassic Erdenet porphyry Cu-Mo deposit, in northern Mongolia, developed in a continent-continent arc collision zone, within the Central Asian orogenic belt. The porphyry system is related to multiple intrusions of crystal-crowded biotite granodiorite porphyry, which formed a composite stock about 900 m in diameter, with...
Submersed aquatic vegetation in Chesapeake Bay: Sentinel species in a changing world

2017, BioScience (67) 698-712
Chesapeake Bay has undergone profound changes since European settlement. Increases in human and livestock populations, associated changes in land use, increases in nutrient loadings, shoreline armoring, and depletion of fish stocks have altered the important habitats within the Bay. Submersed aquatic vegetation (SAV) is a critical foundational habitat and provides...
