Robert Massatti, Daniel E. Winkler, Sasha C. Reed, Michael C. Duniway, Seth M. Munson, John B. Bradford
2020, Report
A primary focus of the Bureau of Land Management’s (BLM’s) Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration...
Reconstruction of an early Permian, sublacustrine magmatic-hydrothermal system: Mount Carlton epithermal Au-Ag-Cu deposit, northeastern Australia
Fredrik Sahlstrom, Zhaoshan Chang, Antonio Arribas , Paul Dirks, Craig A. Johnson, Jan M Huizenga, Isaac Corral
2020, Economic Geology (115) 129-152
The Mt. Carlton Au-Ag-Cu deposit, northern Bowen basin, northeastern Australia, is an uncommon example of a sublacustrine hydrothermal system containing economic high-sulfidation epithermal mineralization. The deposit formed in the early Permian and comprises vein- and hydrothermal breccia-hosted Au-Cu mineralization within a massive rhyodacite porphyry (V2 open pit) and stratabound Ag-barite...

Bug flows: Don’t count your midges until they hatch
Anya Metcalfe, Jeffrey Muehlbauer, Morgan Ford, Theodore Kennedy
2020, Newsletter
Usually when people hear about a “bug problem” it’s due to an undesirable overabundance of insects (think plague of locusts). In the Colorado River in Grand Canyon, however, we are faced with the opposite predicament: the river is essentially devoid of bugs. Aquatic insects are a fundamental component of a...

Understanding the impacts of surface-groundwater conditions on stream fishes under altered baseflow conditions
Shannon K. Brewer, G. Fox, Y. Zhou, J. Alexander
2020, Cooperator Science Series CSS-136-2020
Persistence of aquatic fauna depends on the conditions and connectivity of surface water and groundwater. In light of altered baseflows and both current and future predicted increases in stream temperatures, it is important to assess current thermal conditions, examine thermal responses of aquatic fauna, and evaluate water-management practices. Our study...

R. K. Owen, Elisabeth B. Webb, David A. Haukos, F. B. Fritschi, K. W. Goyne
2020, Wetlands Ecology and Management (28) 35-50
Projected twenty first century increases in temperature and precipitation intensity in the U.S. Great Plains may alter playa wetland hydroperiods. Our objective was to identify favorable germination conditions for a common moist-soil grass, Barnyardgrass (Echinochloa crusgalli L.), by evaluating emergence and growth response to various environmental conditions specific to the Northern...
Using advanced population genomics to better understand the relationship between offshore and spawning habitat use for Atlantic Sturgeon
David C. Kazyak, Aaron Aunins, Robin L. Johnson, Barbara A. Lubinski, Michael S. Eackles, Tim L. King
2020, OCS Study 2020-062
Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus) are a large-bodied anadromous fish that historically supported important fisheries along the east coast of the United States. Following years of overharvest and habitat degradation, populations experienced severe declines. In 2012, the National Marine Fisheries Service listed Atlantic Sturgeon under the Endangered Species Act (ESA;...

Erin E. Hahn, Anastasia Klimova, Adrian Munguia-Vega, Kevin B. Clark, Melanie Culver
2020, Journal of Wildlife Management (64) 524-533
Endangered Sonoran (Antilocapra americana sonoriensis) and Peninsular (A. a. peninsularis) pronghorn persist largely because of captive breeding and reintroduction efforts. Recovery team managers want to re-establish pronghorn in their native range, but there is currently uncertainty regarding the subspecies status of extinct pronghorn populations that historically...
Patterns and drivers of atmospheric river precipitation and hydrologic impacts across the western United States
Christine M. Albano, Michael D. Dettinger, Adrian Harpold
2020, Journal of Hydrometeorology (21) 143-159
Atmospheric rivers (ARs) significantly influence precipitation and hydrologic variability in many areas of the world, including the western United States. As ARs are increasingly recognized by the research community and the public, there is a need to more precisely quantify and communicate their hydrologic impacts, which can vary from hazardous...
Benthic infaunal communities of Baltimore and Norfolk Canyons
Craig M. Robertson, Jill R. Bourque, Amanda Demopoulos
2020, Report
The imperative for finding, cataloging, and understanding continental margin diversity derives from the many key functions, goods and services provided by margin ecosystems and by an increasingly deleterious human footprint on our continental slopes (Levin and Dayton 2009). Progress in seafloor mapping technology and direct observation has revealed unexpected heterogeneity, with a...
Semiautomated process for enumeration of fishes from recreational-grade side-scan sonar imagery
Katelyn M Lawson, Josey Lee Ridgway, Andrew T. Mueller, Jacob Faulkner, Robin D. Calfee
2020, North American Journal of Fisheries Management (40) 75-83
The use of hydroacoustic techniques is increasing as scientists search for less invasive ways to monitor fish populations, and using recreational side‐scan sonar (SSS) imagery for monitoring has become more common in aquatic resource management over the last 15 years due in part to its low cost and user‐friendly interface....

Over 80% of the Mid-Continent Sandhill Crane (Antigone canadensis) Population (MCP), estimated at over 660,000 individuals, stops in the Central Platte River Valley (CPRV) during spring migration from mid-February through mid-April. Research suggests that the MCP may be shifting its distribution spatially and temporally within the CPRV. From 2002 to...

2020, Conference Paper, 111th New England Intercollegiate Geological Conference
The Cretaceous Ascutney Mountain igneous complex affords a classic exposure of the White Mountain Igneous Suite. Often called Vermont’s most famous volcano, Mount Ascutney (elev. 3,144 feet, 958 m) stands as a prominent monadnock in the Connecticut River Valley. The mountain often serves as an inspirational landmark, as it...
Micrometer-scale characterization of solid mine waste aids in closure due diligence
Bryn E. Kimball, Heather E. Jamieson, Robert R. Seal, II, Agatha Dobosz, Nadine M. Piatak
2020, Conference Paper, Proceedings of tailings and mine waste 2019
Precious- and base-metal mining often occurs in deposits with high acid-generating potential, resulting in mine waste that contains metals in forms of varying bioavailability, and therefore toxicity. The solids that host these metals are often noncrystalline, nanometer to micrometer in size, or undetectable by readily available analytical techniques (e.g., X-ray...
Establishing high-frequency noise baselines to 100 Hz based on millions of power spectra from IRIS MUSTANG
Emily Wolin, Daniel McNamara
2020, Bulletin of the Seismological Society of America (110) 270-278
Advances in seismic instrumentation have enabled data to be recorded at increasing sample rates. This has in turn created a need to establish higher-frequency baselines for assessing data quality, as the widely-used New High (NHNM) and Low Noise Models (NLNM) of Peterson (1993) do not extend to frequencies above...
Integrating multiple data sources and multi-scale land-cover data to model the distribution of a declining amphibian
Jonathan P. Rose, Brian J. Halstead, Robert N. Fisher
2020, Biological Conservation (241)
Determining the spatial scale at which landscape features influence population persistence is an important task for conservation planning. One challenge is that sampling biases confound factors that influence species occurrence and survey effort. Recent developments in Point Process Models (PPMs) enable researchers to disentangle the sampling process from ecological drivers...
