2016, Global Biogeochemical Cycles (30) 1811-1826
Recent climate change in the Arctic is driving permafrost thaw, which has important implications for regional hydrology and global carbon dynamics. Permafrost is an important control on groundwater dynamics and the amount and chemical composition of dissolved organic matter (DOM) transported by high-latitude rivers. The consequences of permafrost thaw for...
Effects of flow regime on metal concentrations and the attainment of water quality standards in a remediated stream reach, Butte, Montana
Robert L. Runkel, Briant A. Kimball, David A. Nimick, Katherine Walton-Day
2016, Environmental Science & Technology (50) 12641-12649
Low-flow synoptic sampling campaigns are often used as the primary tool to characterize watersheds affected by mining. Although such campaigns are an invaluable part of site characterization, investigations which focus solely on low-flow conditions may yield misleading results. The objective of this paper is to demonstrate this point and elucidate...

2016, Report, The impacts of climate change on human health in the Untited States: A scientific assessment
Climate change is already causing, and is expected to continue to cause, a range of health impacts that vary across different population groups in the United States. The vulnerability of any given group is a function of its sensitivity to climate change related health risks, its exposure to those risks,...

Cynthia S.A. Wallace, Jessica J. Walker, Susan M. Skirvin, Caroline Patrick-Birdwell, Jake F. Weltzin, Helen Raichle
2016, Remote Sensing (8) 1-24
The increasing spread and abundance of an invasive perennial grass, buffelgrass (Pennisetum ciliare), represents a critical threat to the native vegetation communities of the Sonoran desert in southern Arizona, USA, where buffelgrass eradication is a high priority for resource managers. Herbicidal treatment of buffelgrass is most effective when the vegetation...
Pan-arctic trends in terrestrial dissolved organic matter from optical measurements
Paul J. Mann, Robert G. M. Spencer, Peter J. Hernes, Johan Six, George R. Aiken, Suzanne E. Tank, James W. McClelland, Kenna D. Butler, Rachael Y. Dyda, Robert M. Holmes
2016, Frontiers in Earth Science (4)
Climate change is causing extensive warming across Arctic regions resulting in permafrost degradation, alterations to regional hydrology and shifting amounts and composition of dissolved organic matter (DOM) transported by streams and rivers. Here, we characterize the DOM composition and optical properties of the six largest Arctic rivers draining into the...
Mineral resources: Reserves, peak production and the future
Lawrence D. Meinert, Gilpin Robinson, Nedal T. Nassar
2016, Resources (5)
The adequacy of mineral resources in light of population growth and rising standards of living has been a concern since the time of Malthus (1798), but many studies erroneously forecast impending peak production or exhaustion because they confuse reserves with “all there is”. Reserves are formally defined as a subset...
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...
Measuring distance “as the horse runs”: Cross-scale comparison of terrain-based metrics
Barbara P. Buttenfield, M Ghandehari, S Leyk, Larry V. Stanislawski, M E Brantley, Yi Qiang
2016, Conference Paper
Distance metrics play significant roles in spatial modeling tasks, such as flood inundation (Tucker and Hancock 2010), stream extraction (Stanislawski et al. 2015), power line routing (Kiessling et al. 2003) and analysis of surface pollutants such as nitrogen (Harms et al. 2009). Avalanche risk is based on slope, aspect, and...
A Tour de Force by Hawaii's invasive mammals: establishment, takeover, ecosystem restoration through eradication
Steve C. Hess
2016, Conference Paper, 27th Vertebrate Pest Conference
Invasive mammals, large and small, have irreversibly altered Hawaii's ecosystems in numerous cases through unnatural herbivory, predation, and the transmission of zoonotic diseases, thereby causing the disproportionate extinction of flora and fauna that occur nowhere else on Earth. The control and eradication of invasive mammals is the single most expensive...

2016, Conference Paper
The recent Kaohsiung Meinong Earthquake which occurred on February 6, 2016 affected several categories of building stock for which risk identification programs were previously developed by NCREE. A typical building type in the city of Tainan is a mixed-use three-to-five-story structure. The ground floor of this typical structure is an...
Modeling martian thermal inertia in a distributed memory high performance computing environment
Jason Laura, Robin L. Fergason
2016, Conference Paper, Proceedings 2016 IEEE international conference on big data
Modeling martian surface properties fusing high resolution, spatially enabled, remotely sensed data and derived thermophysical modeling is an essential tool for surface property characterization studies. In this work, we describe the development of a thermal inertia modeling tool that integrates the KRC thermal model and a nine-dimensional parameter interpolation with...
Thiamine and lipid utilization in fasting Chinook salmon
Dale C. Honeyfield, A. K. Peters, Michael L. Jones
2016, North Pacific Anadromous Fish Commission Bulletin (6) 13-19
A laboratory study was conducted to estimate utilization rates of thiamine (vitamin B1) and lipid in whole fish, muscle, and liver tissues of fasting Chinook salmon (Oncorhynchus tshawytscha). The experiment was conducted with Chinook salmon held at 5ºC over a period of 150 days to simulate fasting during migration or...

2016, Book chapter, Effects of drought on forests and rangelands in the United States: A comprehensive science synthesis. Gen. Tech. Rep. WO-93b
Historical and presettlement relationships between drought and wildfire have been well documented in much of North America, with forest fire occurrence and area burned clearly increasing in response to drought. Drought interacts with other controls (forest productivity, topography, and fire weather) to affect fire intensity and severity. Fire regime characteristics...
Life history and status of Shortnose Sturgeon (Acipenser brevirostrum LeSueur, 1818)
Boyd Kynard, Stephania Bolden, Micah Kieffer, Mark Collins, Hal Brundage, Eric Hilton, Mark Litvak, Michael T. Kinnison, Tim L. King, Douglas C. Peterson
2016, Journal of Applied Ichthyology (32) 208-248
Shortnose Sturgeon = SNS (Acipenser brevirostrum) is a small diadromous species with most populations living in large Atlantic coast rivers and estuaries of North America from New Brunswick, Canada, to GA, USA. There are no naturally landlocked populations, so all populations require access to fresh water and salt water to...
Resource potential for commodities in addition to Uranium in sandstone-hosted deposits
George N. Breit
2016, Book chapter, Rare earth and critical elements in ore deposits
Sandstone-hosted deposits mined primarily for their uranium content also have been a source of vanadium and modest amounts of copper. Processing of these ores has also recovered small amounts of molybdenum, rhenium, rare earth elements, scandium, and selenium. These deposits share a generally common origin, but variations in the source...
Use of lidar point cloud data to support estimation of residual trace metals stored in mine chat piles in the Old Lead Belt of southeastern, Missouri
Emitt C. Witt III
2016, AIMS Environmental Science (3) 509-524
Historic lead and zinc (Pb-Zn) mining in southeast Missouri’s ―Old Lead Belt‖ has left large chat piles dominating the landscape where prior to 1972 mining was the major industry of the region. As a result of variable beneficiation methods over the history of mining activity, these piles remain with large...

2016, Science Activities (53) 147-154
We present a hands-on outdoor activity coupled with classroom discussion to teach students about wildlife habitat selection, the process by which animals choose where to live. By selecting locations or habitats with many benefits (e.g., food, shelter, mates) and few costs (e.g., predators), animals improve their ability to survive and...
