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...
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...

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...
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...

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...

Jessica Laskowski, Caitlyn R. Gillespie, Lucia Corral, Amy Oden, Kent A. Fricke, Joseph J. Fontaine
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...
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, Reviews of Geophysics (54) 447-485
Natural dust is often associated with hot, subtropical deserts, but significant dust events have been reported from cold, high latitudes. This review synthesizes current understanding of high-latitude (≥50°N and ≥40°S) dust source geography and dynamics and provides a prospectus for future research on the topic. Although the fundamental processes controlling...

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...

2016, Report, EERI Earthquake Reconnaissance Team Report: M7.8 Gorkha, Nepal Earthquake on April 25, 2015 and its Aftershocks
The most common building typologies in Nepal are reinforced concrete (RC) frame buildings with masonry infill walls, unreinforced masonry (URM) bearing wall buildings, and wood frame buildings (Figure 5-1). The RC frames with masonry infills are commonly constructed in urban and semi-urban areas. Most of these buildings are three to...

2016, Stratigraphy (13) 303-305
The Pliocene, specifically the late Pliocene, has been a focus of paleoclimate research formore than 25 years. Synoptic regional and global reconstructions along with high-resolution time-series have produced nuanced conceptual models of paleoenvironmental conditions and enhanced our understanding of climate variability and climate sensitivity from the Late Pliocene, the most recent interval of...

Allison H. Roy, Stephen F. Jane, Peter D. Hazelton, Todd A. Richards, John T. Finn, Timothy O. Randhir
2016, Cooperator Science Series 122-2016
With increased pressure from a growing human population, managers are challenged to understand how novel disturbances (e.g., climate change, increased water withdrawals, urbanization) may affect natural resources. The Sudbury River is a National Wild and Scenic River located in suburban Boston, Massachusetts (Northeastern US) with myriad impairments (e.g., mainstem impoundments,...
Participatory modeling and structured decision making
Kelly F. Robinson, Angela K. Fuller
2016, Book chapter, Environmental Modeling with Stakeholders
Structured decision making (SDM) provides a framework for making sound decisions even when faced with uncertainty, and is a transparent, defensible, and replicable method used to understand complex problems. A hallmark of SDM is the explicit incorporation of values and science, which often includes participation from multiple stakeholders, helping to...
Leveraging constraints and biotelemetry data to pinpoint repetitively used spatial features
Brian M. Brost, Mevin Hooten, Robert J. Small
2016, Ecology (98) 12-20
Satellite telemetry devices collect valuable information concerning the sites visited by animals, including the location of central places like dens, nests, rookeries, or haul‐outs. Existing methods for estimating the location of central places from telemetry data require user‐specified thresholds and ignore common nuances like measurement error. We present a fully...

2016, Icarus (278) 279-300
A history of martian surface changes is documented by a sequence of global mosaics made up of Mars Global Surveyor Mars Orbiter Camera daily color images from 1999 to 2006, together with a single mosaic from the Mars Reconnaissance Orbiter Mars Color Imager in 2009. These observations show that changes...
Nonmarine facies in the Late Triassic(?) to Early Jurassic Horn Mountain Tuff member of the Talkeetna Formation, Horn Mountain, lower Cook Inlet basin, Alaska
D. L. LePain, Richard G. Stanley, K. P. Helmold
2016, Preliminary Interpretive Report 2016-1-2
The Talkeetna Formation is a prominent lithostratigraphic unit in south-central Alaska. In the Iniskin–Tuxedni area, Detterman and Hartsock (1966) divided the formation into three mappable units including, from oldest to youngest, the Marsh Creek Breccia, the Portage Creek Agglomerate, and the Horn Mountain Tuff Members. The Horn Mountain Tuff Member...
