Joseph E. Beman
2020, Data Series 1129
The Albuquerque Basin, located in central New Mexico, is about 100 miles long and 25–40 miles wide. The basin is hydrologically defined as the extent of consolidated and unconsolidated deposits of Tertiary and Quaternary age that encompasses the structural Rio Grande Rift between San Acacia to the south and Cochiti...
Applications of deep convolutional neural networks to predict length, circumference, and weight from mostly dewatered images of fish
Nicholas Bravata, Dylan Kelly, Jesse Eickholt, Janine Bryan, Scott M. Miehls, Daniel Zielinski
2020, Ecology and Evolution (10) 9313-9325
Simple biometric data of fish aid fishery management tasks such as monitoring the structure of fish populations and regulating recreational harvest. While these data are foundational to fishery research and management, the collection of length and weight data through physical handling of the fish is challenging as it is time...
Adjusted geomagnetic data—Theoretical basis and validation
E. Joshua Rigler, Abram E. Claycomb
2020, Open-File Report 2020-1053
Adjusted geomagnetic data are magnetometer measurements with provisional correction factors applied such that vector quantities are oriented in a local Cartesian frame in which the X axis points north, the Y axis points east, and the Z axis points down. These correction factors are determined from so-called absolute measurements, which...
Laboratory electrical conductivity of marine gas hydrate
Steven Constable, Ryan Lu, Laura A. Stern, Wyatt L. Du Frane, Jeffery J. Roberts
2020, Geophysical Research Letters (47)
Methane hydrate was synthesized from pure water ice and flash frozen seawater, with varying amounts of sand or silt added. Electrical conductivity was determined by impedance spectroscopy, using equivalent circuit modeling to separate the effects of electrodes and to gain insight into conduction mechanisms. Silt and sand...

2020, Open-File Report 2020-1063
Executive SummaryThere is a growing body of tools available for science support for determining the fate and behavior of industrial and agricultural chemicals that are rapidly injected (“spilled”) into aquatic environments. A 2-day roundtable-style workshop was held by the U.S. Geological Survey (USGS) in Middleton, Wisconsin, in December 2017 to...
Macroinvertebrate oviposition habitat selectivity and egg-mass desiccation tolerances: Implications for population dynamics in large regulated rivers
Scott W. Miller, Matt Schroer, Jesse R. Fleri, Theodore A. Kennedy
2020, Freshwater Science (39) 584-599
Aquatic insects exhibit complex life cycles that include egg, larval, adult, and, in some instances, pupal stages. Disturbances at any of these life stages can affect overall population dynamics. Yet, efforts to understand the effects of disturbances, such as hydrologic alterations, overwhelmingly focus on the larval life stage of aquatic...

Passive acoustic monitoring effectively detects Northern Spotted Owls and Barred Owls over a range of forest conditions
Leila S. Duchac, Damon B. Lesmeister, Katie M. Dugger, Zachary J. Ruff, Raymond J. Davis
2020, Condor (122)
Passive acoustic monitoring using autonomous recording units (ARUs) is a fast-growing area of wildlife research especially for rare, cryptic species that vocalize. Northern Spotted Owl (Strix occidentalis caurina) populations have been monitored since the mid-1980s using mark–recapture methods. To evaluate an alternative survey method, we used ARUs to detect calls...

Michael T. Bland, Lynn A. Weller, David Mayer, Brent A. Archinal
2020, Conference Paper, ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
A planetary bodys global shape provides both insight into its geologic evolution, and a key element of any Planetary Spatial Data Infrastructure (PSDI). NASAs Cassini mission to Saturn acquired more than 600 moderate- to high-resolution images (< 500 m/pixel) of the small, geologically active moon Enceladus. The moons internal global...

Citizen scientists record novel leaf phenology of invasive shrubs in eastern U.S. forests
Erynn E. Maynard-Bean, Margot Kaye, Tyler Wagner, Eric P. Burkhart
2020, Biological Invasions (22) 3325-3337
Invasive shrubs are an emergent concern in deciduous forests of eastern North America. Their extended leaf phenology (ELP) – earlier leaf emergence and later leaf off compared to native shrubs and the overstory canopy – can simultaneously provide photosynthetic benefits to invasive shrubs while negatively affecting native flora and fauna...

The Midcontinent Rift System (MRS) of North America is one of the world’s largest continental rifts and has an age of 1.1 Ga (giga-annum). The MRS hosts a diverse suite of magmatic and hydrothermal mineral deposits in the Lake Superior region where rift rocks are exposed at or near the...
Soil organic carbon stocks and sequestration rates of inland, freshwater wetlands: Sources of variability and uncertainty
Brian Tangen, Sheel Bansal
2020, Science of the Total Environment (749)
Impacts of land use, specifically soil disturbance, are linked to reductions of soil organic carbon (SOC) stocks. Correspondingly, ecosystem restoration is promoted to sequester SOC to mitigate anthropogenic greenhouse gas emissions, which are exacerbating global climate change. Restored wetlands have relatively high potential to...

Shawn T. O’Neil, Peter S. Coates, Brianne E. Brussee, Mark A. Ricca, Shawn P. Espinosa, Scott C. Gardner, David J Delahanty
2020, Global Change Biology (26) 6296-6312
Globally accelerating frequency and extent of wildfire threatens the persistence of specialist wildlife species through direct loss of habitat and indirect facilitation of exotic invasive species. Habitat specialists may be especially prone to rapidly changing environmental conditions because their ability to adapt lags behind the rate...

Jeffry Bernardy, Cheryl Kaye, Nicholas Schloesser, Justin Schueller
2020, Report
Temporal and spatial distribution of niclosamide in the water column and sediment were evaluated after the application of granular Bayluscide in six lentic sea lamprey (Petromyzon marinus) larval assessment plots. Water and sediment were collected 0.25, 1, 3, 5, and 7 hours after application and were analyzed for niclosamide, the...

Dual clumped isotope thermometry resolves kinetic biases in carbonate formation temperatures
David Bajnai, Weifu Guo, Christoph Spotl, Tyler B. Coplen, Katharina Methner, Niklas Loffler, Emilija Krsnik, Eberhard Gischler, Maximilian Hansen, Daniela Henkel, Gregory D. Price, Jacek Raddatz, Denis Scholz, Jens Fiebig
2020, Nature Communications (11)
Surface temperature is a fundamental parameter of Earth’s climate. Its evolution through time is commonly reconstructed using the oxygen isotope and the clumped isotope compositions of carbonate archives. However, reaction kinetics involved in the precipitation of carbonates can introduce inaccuracies in the derived temperatures. Here, we show that dual clumped...
A fishery after the decline: The Susquehanna River Smallmouth Bass story
Megan K. Schall, Geoffrey D. Smith, Vicki S. Blazer, Heather L. Walsh, Yan Li, Tyler Wagner
2020, Fisheries Magazine (45) 576-584
The Smallmouth Bass Micropterus dolomieu fishery in the Susquehanna River basin, Pennsylvania, is one of the most socioeconomically important fisheries in the region and has recently undergone considerable changes. These changes started in 2005, when disease was documented in young-of-the-year (age-0) Smallmouth Bass. Shortly thereafter, declines in abundance of both juveniles and...

2020, Biological Conservation (250)
Found throughout the tree of life and in every ecosystem, parasites are some of the most diverse, ecologically important animals on Earth—but in almost all cases, the least protected by wildlife or ecosystem conservation efforts. For decades, ecologists have been calling for research to understand parasites' important ecological role, and...
