Main-stem seepage and base-flow recession time constants in the Niobrara National Scenic River Basin, Nebraska, 2016–18
Kellan R. Strauch, Philip J. Soenksen
2022, Scientific Investigations Report 2021-5102
The Niobrara River of northern Nebraska is a valuable water resource that sustains irrigated agriculture and recreation, as well as a diverse ecosystem. Large-quantity withdrawals from the source aquifer system have the potential to reduce the flow into the river and to adversely affect the free-flowing condition of the Niobrara...
Structural and functional landscape connectivity for lesser prairie-chickens in the Sand Shinnery Oak Prairie Ecoregion
L.J. Schilder, L.J. Heintzman, N.E. Mcintyre, S. Harryman, C.A. Hagen, R. E. Martin, Clint W. Boal, Blake A. Grisham
2022, Journal of Wildlife Management (86)
The lesser prairie-chicken (Tympanuchus pallidicinctus) is a species of conservation concern on the Southern High Plains of Texas and New Mexico, USA. Because fragmentation and isolation have increased since pre-settlement, dispersal through this heterogeneous landscape may be constrained, with serious implications for conservation and management of this species. Our objectives...

Colin S. Peake, Timothy O. Hodson
2022, Scientific Investigations Report 2021-5125
The Des Plaines River in southern Wisconsin and northern Illinois is the principal conduit for the discharge of wastewater effluent and stormwater runoff from the greater Chicago metropolitan area. In November 2017, the U.S. Geological Survey, in cooperation with the Metropolitan Water Reclamation District of Greater Chicago, installed a continuous...
Contributing areas to domestic wells in dipping sedimentary rocks under extreme recharge events
Claire R. Tiedeman, Allen M. Shapiro
2022, Groundwater (60) 460-476
We use particle tracking to determine contributing areas (CAs) to wells for transient flow models that simulate cyclic domestic pumping and extreme recharge events in a small synthetic watershed underlain by dipping sedimentary rocks. The CAs consist of strike-oriented bands at locations where the water table intersects high-hydraulic conductivity beds,...
Disease and secondary sexual traits: Effects of pneumonia on horn size of bighorn sheep
Alynn Martin, John T. Hogg, Kezia R. Manlove, Tayler N LaSharr, Justin M. Shannon, Douglas E. McWhirter, Hollie Miyasaki, Kevin L. Monteith, Paul C. Cross
2022, Journal of Wildlife Management (86)
Secondary sexual traits (e.g., horns and antlers) have ecological and evolutionary importance and are of management interest for game species. Yet, how these traits respond to emerging threats like infectious disease remains underexplored. Infectious pneumonia threatens bighorn sheep (Ovis canadensis) populations across North America and we...

2022, Ecological Indicators (135)
Widespread amphibian declines were well documented at the end of the 20th century, raising concerns about the need to identify individual and interactive contributors to this global trend. At the same time, there was growing interest in the use of amphibians...
Weakly supervised spatial deep learning for Earth image segmentation based on imperfect polyline labels
Zhe Jiang, Wenchong He, M. S. Kirby, Arpan Man Sainju, Shaowen Wang, Larry Stanislawski, Ethan J. Shavers, E. Lynn Usery
2022, ACM Transactions on Intelligent Systems and Technology (13)
In recent years, deep learning has achieved tremendous success in image segmentation for computer vision applications. The performance of these models heavily relies on the availability of large-scale high-quality training labels (e.g., PASCAL VOC 2012). Unfortunately, such large-scale high-quality training data are...

Robin S Matoza, Bernard A Chouet, A.D. Jolly, Phillip B. Dawson, Rebecca H Fitzgerald, Ben M. Kennedy, David Fee, Alexandra M. Iezzi, Geoff N Kilgour, E. Garaebiti, Sandrine Cevuard
2022, Geophysical Journal International (230) 392-426
Yasur volcano, Vanuatu is a continuously active open-vent basaltic-andesite stratocone with persistent and long-lived eruptive activity. We present results from a seismo-acoustic field experiment at Yasur, providing locally dense broad-band seismic and infrasonic network coverage from 2016 July 27 to August 3. We corroborate our seismo-acoustic observations with coincident...

Mark A. Kirk, Bryan M. Maitland, Brian T. Hickerson, Annika W. Walters, Frank J. Rahel
2022, Biological Invasions (24) 1311-1326
Smallmouth bass (Micropterus dolomieu) are a globally introduced fish species that have experienced widespread range expansions in recent decades and which can have deleterious effects on native fish communities. Rapidly assessing their expansions will aid conservation and management actions geared towards controlling their spread and mitigating their impacts. Smallmouth bass...
Landscape and stocking effects on population genetics of Tennessee Brook Trout
John S. Hargrove, David C. Kazyak, Barbara A. Lubinski, Karli M. Rogers, Olivia K. Bowers, Kurt A. Fesenmyer, Jim W. Habera, Jason Henegar
2022, Conservation Genetics (23) 341-357
Throughout their range, Brook Trout (Salvelinus fontinalis) occupy thousands of disjunct drainages with varying levels of disturbance, which presents substantial challenges for conservation. Within the southern Appalachian Mountains, fragmentation and genetic drift have been identified as key threats to the genetic diversity of the Brook Trout...
Late Jurassic-Early Cretaceous orogenic gold mineralization in the Klamath Mountains, California: Constraints from 40Ar/39Ar dating of hydrothermal muscovite
Ryan D. Taylor, Leah E. Morgan, Fred Jourdan, Thomas Monecke, Erin E. Marsh, Richard J. Goldfarb
2022, Ore Geology Reviews (141)
The Klamath Mountains gold province is the second most important historical producer in California, having produced more than 7 Moz of gold from both lode and placer sources. Hydrothermal muscovite grains from gold-bearing veins provide the first 40Ar/39Ar age constraints indicative of a protracted period...

Benjamin Choat, Amber Pulido, Aditi S. Bhaskar, Rebecca Hale, Harry X. Zhang, Thomas Meixner, Lauren McPhillips, Kristina G. Hopkins, Jennifer Cherrier, Chingwen Cheng
2022, Journal of Sustainable Water in the Built Environment (8) 1-10
Urban stormwater is an ongoing contributor to the degradation of the health of many watersheds and water bodies. In the United States, federal regulations (e.g., Clean Water Act) require monitoring and reporting of relevant water quality metrics in regulated waterbodies to ensure standards are being met, but decisions about how...
A web-based tool for assessing the condition of benthic diatom assemblages in streams and rivers of the conterminous United States
Daren M. Carlisle, Sarah A. Spaulding, Meredith Tyree, Nicholas O. Schulte, Sylvia S Lee, Richard M. Mitchell, Amina A. Pollard
2022, Ecological Indicators (135)
Benthic diatom assemblages are known to be indicative of water quality but have yet to be widely adopted in biological assessments in the United States due to several limitations. Our goal was to address some of these limitations by developing regional multi-metric indices (MMIs) that are robust to inter-laboratory taxonomic...

2022, North American Journal of Fisheries Management (42) 484-506
Walleye Sander vitreus and Yellow Perch Perca flavescens are culturally, economically, and ecologically significant fish species in North America that are affected by drivers of global change. Here, we review and synthesize the published literature documenting the effects of ecosystem changes on Walleye and Yellow Perch. We focus on four drivers: climate (including temperature...
Influence of anthropogenic subsidies on movements of common ravens
Adam E. Duerr, Peter H. Bloom, Kerry Ross, Tricia A. Miller, Melissa A. Braham, Amy L Fesnock, Todd E. Katzner
2022, Human-Wildlife Interactions (15) 1-13
Anthropogenic subsidies can benefit populations of generalist predators such as common ravens (ravens; Corvus corax), which in turn may depress populations of many types of species at lower-trophic levels, including desert tortoises (Gopherus agassizii) or greater sage-grouse (Centrocercus urophasianus). Management of subsidized ravens often has targeted local breeding populations that...

2022, Oil & Gas Journal (120) 46-53
The revision of federal safety regulations for integrity management of gas transmission pipelines to require explicit consideration of seismicity increases the importance for operators to be actively identifying high-consequence areas (HCAs), evaluating seismic-related threats, and choosing a risk model to support risk management decisions. To ensure equal access to information...
