Klamath natural flow study, Upper Klamath Basin groundwater flow model
Jonathan A. Traum, Scott Boyce
2022, Report
The purpose of the Upper Klamath Basin Groundwater Flow Model (UKBGFM) is to simulate groundwater conditions in the Upper Klamath Basin under historical and predevelopment conditions. The UKBGFM quantifies estimates of and changes in groundwater levels, storage, pumping, drainage flow to tile drains, evapotranspiration, and flow between the Upper Klamath...
Spatial extent of seagrasses (Zostera marina and Ruppia maritima) along the central Pacific coast of Baja California, Mexico, 1999–2000
David H. Ward, Alexandra Morton, Carl J. Markon, Kyle R. Hogrefe
2022, Open-File Report 2022-1004
The seagrasses eelgrass (Zostera marina) and widgeongrass (Ruppia maritima) are prominent features of coastal lagoons along the Pacific coast of Baja California, Mexico, supporting a rich diversity of marine life. Yet little is known about their spatial distribution in this region. This is a concern because of declining trends...
Plant community trajectories following livestock exclusion for conservation vary and hinge on initial invasion and soil-biocrust conditions in shrub steppe
Matthew J. Germino, Chad Raymond Kluender, Christopher R. Anthony
2022, Conservation Science and Practice (4)
Adjustments or complete withdrawal of livestock grazing are among the most common conservation actions in semiarid uplands, but outcomes can vary considerably with ecological context. Invasion by exotic annual grasses and the excessive wildfire they promote are increasing threats to semiarid shrub-steppe, and plant-community response to...
Abundance of eelgrass (Zostera marina) at key Black Brant (Branta bernicla nigricans) wintering sites along the northern Pacific coast of Baja California, Mexico, 1998–2012
David H. Ward
2022, Open-File Report 2022-1078
Trends in the abundance and distribution of eelgrass (Zostera marina), the primary winter forage of black brant (Branta bernicla nigricans), was evaluated at three major wintering sites for black brant along the northern Pacific coast of Baja California, Mexico. This region of northwestern Mexico contains significant beds of eelgrass...
Bulk and intramolecular carbon isotopic compositions of hydrocarbon gases from laboratory pyrolysis of oil shale of the Green River Formation: Implications for isotope structures of kerogens
Xiaoqiang Li, Justin E. Birdwell, Juske Horita
2022, International Journal of Coal Geology (264)
Evaluation of intramolecular isotope distributions within organic compounds can provide important insights into gas formation processes and structural properties of gas-generating precursors, such as kerogen, bitumen, and oil, in natural reservoirs. Until recently, little has been known about the intramolecular isotope...
Backpack electrofishing does not contribute to external signs of gas bubble trauma in sculpins
Kenneth F. Tiffan, Nicole Joy Eller
2022, Aquaculture, Fish and Fisheries (2) 572-577
We exposed prickly sculpin Cottus asper and reticulate sculpin Cottus perplexus to electroshock and sham treatments in a controlled laboratory setting to determine if backpack electrofishing contributed to or exacerbated external signs of gas bubble trauma (GBT) in fish exposed to elevated total dissolved gas (TDG) levels. Fish were exposed to 115, 120 and...
Availability of lesser prairie-chicken nesting habitat impairs restoration success
Liam A. Berigan, Carly S. H. Aulicky, Elisabeth C. Teige, Daniel S. Sullins, David A. Haukos, Kent A. Fricke, Jonathan H. Reitz, Liza G. Rossi, Kraig A. Schultz, Andrew Ricketts
2022, Wildlife Society Bulletin (46)
Regional populations of lesser prairie-chickens (Tympanuchus pallidicinctus) have been declining irregularly since the early 1900s (Jensen et al. 2000). Populations in the Sand Sagebrush Prairie Ecoregion of Kansas and Colorado, USA, have been experiencing declines during the last 2 decades. Ecoregion-wide declines included the Cimarron and Comanche National Grasslands in...

Brian D. Andrews, Daniel S. Brothers, Peter Dartnell, J. Vaughn Barrie, Peter J. Haeussler, Kristen M. Green, H. Gary Greene, Nathaniel C. Miller, Jared W. Kluesner, Uri S. ten Brink
2022, Open-File Report 2022-1085
In 2015, U.S. Geological Survey scientists in collaboration with scientists from other institutions began a study of the Queen Charlotte fault—the first systematic study of the fault in more than three decades. The primary goal of the study was to gain a better understanding of the earthquake, tsunami, and underwater-landslide...

Kuffner, J L Matthews, Miguel Medina, C P Meyer, C Oster, J T Price, H M Putnam, Y Sawall
2022, PeerJ (10)
Coral reefs are declining worldwide primarily because of bleaching and subsequent mortality resulting from thermal stress. Currently, extensive efforts to engage in more holistic research and restoration endeavors have considerably expanded the techniques applied to examine coral samples. Despite such advances, coral bleaching and restoration studies are often conducted...
Contemporary (1984–2020) fire history metrics for the conterminous United States and ecoregional differences by land ownership
Melanie K. Vanderhoof, Todd Hawbaker, Casey Teske, Joe Noble, Jim Smith
2022, International Journal of Wildland Fire (31) 1167-1183
Background: Remotely sensed burned area products are critical to support fire modelling, policy, and management but often require further processing before use.Aim: We calculated fire history metrics from the Landsat Burned Area Product (1984–2020) across the conterminous U.S. (CONUS) including (1) fire frequency, (2) time since last burn (TSLB), (3) year of...
Affinity of the benthic foraminifer Cassidulinoides parkeriana (Brady) for whale-falls: Evidence from off western Vancouver Island, British Columbia, Canada
Mary McGann, Charles K. Paull
2022, Micropaleontology (68) 569-586
A partial skeleton of a blue or fin whale, estimated to have been 16.5 m in length and thought to have been lying on the seafloor for less than 10 years, was observed at a depth of 1288 m off western Vancouver Island, British Columbia, Canada (48.68° N, 126.84° W)....
Geologic map of the Mount Blue Sky (formerly Mount Evans) quadrangle, Clear Creek and Park Counties, Colorado

2022, Open-File Report OF-22-11
The Mount Blue Sky (formerly Mount Evans) 7.5’ quadrangle lies in Park and Clear Creek counties, Colorado, about 60 km west of Denver. The highest elevation in the quadrangle is 14,265 ft (4,348 m) at the top of Mount Blue Sky. The lowest is at about 9,200 ft (2,804 m)...
Evaluation of host fishes for the Brook Floater (Alasmidonta varicosa) from populations in Massachusetts and Maine, USA
Ayla J. Skorupa, Allison H. Roy, Peter D. Hazelton, David Perkins, Timothy Warren
2022, Article
The Brook Floater (Alasmidonta varicosa) mussel is globally vulnerable and has disappeared from much of its historical range. Information on Brook Floater host fish use is needed for ecological and conservation purposes, but previous laboratory studies provide conflicting results. We evaluated host fish use by Brook Floater from populations in...

Behavioral responses of native and invasive fishes of the Upper Mississippi River to 100 hp boat motor acoustic stimulus
Kelsie A. Murchy, Brooke J Vetter, Marybeth K. Brey, Allen F. Mensinger
2022, Management of Biological Invasions (13) 750-768
Acoustic deterrents are currently being considered for deployment at strategic bottlenecks, such as lock and dams of major rivers, to deter upstream movement of invasive carp. Previous studies have demonstrated that bighead and silver carp (Hypophthalmichthys nobilis and H. molitrix, respectively) display negative phonotaxis to playbacks of broadband sound recordings produced from...

Influence of test method variables on sensitivity of Neocloeon triangulifer to a reference toxicant in short-term, effluent style evaluations
David J. Soucek, Amy Dickinson, Teresa J. Norberg-King
2022, Environmental Toxicology and Chemistry (41) 2758-2768
Recent literature has demonstrated the sensitivity of mayflies to environmental contaminants. However, to date, there are no methods approved by the US Environmental Protection Agency for using sensitive insects like mayflies in whole-effluent toxicity or receiving water toxicity tests. The parthenogenetic mayfly Neocloeon triangulifer has been shown to be amenable to continuous...
