2016, Ecosphere (7)
Whitebark pine (Pinus albicaulis) forests in the western United States have been adversely affected by an exotic pathogen (Cronartium ribicola, causal agent of white pine blister rust), insect outbreaks (Dendroctonus ponderosae, mountain pine beetle), and drought. We monitored individual trees from 2004 to 2013 and characterized stand-level biophysical conditions through...

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...

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...
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...
A comparison of lead lengths for mini-fyke nets to sample age-0 gar species
James M. Long, Richard A. Snow, Chas P. Patterson
2016, Proceedings of the Oklahoma Academy of Science (96) 28-35
Mini-fyke nets are often used to sample small-bodied fishes in shallow (<1 m depth) water, especially in vegetated shoreline habitats where seines are ineffective. Recent interest in gar (Lepisosteidae) ecology and conservation led us to explore the use of mini-fyke nets to capture age-0 gar and specifically how capture is...

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...

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...

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...
Teaching animal habitat selection using wildlife tracking equipment
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...
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...
Improving our understanding of hydraulic-electrical relations: A case study of the surficial aquifer in Emirate Abu Dhabi
Scott Ikard, Wade H. Kress
2016, Conference Paper, Symposium on the Application of Geophysics to Engineering and Environmental Problems 2016
Transmissivity is a bulk hydraulic property that can be correlated with bulk electrical properties of an aquifer. In aquifers that are electrically-resistive relative to adjacent layers in a horizontally stratified sequence, transmissivity has been shown to correlate with bulk transverse resistance. Conversely, in aquifers that are electrically-conductive relative to adjacent...

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...
