Daniel Monson, Rebecca L. Taylor, Grant Hilderbrand, Joy Erlenbach, Heather Coletti, James L. Bodkin
2022, Journal of Mammalogy
Sea otters were extirpated throughout much of their range by the maritime fur trade in the 18th and 19th centuries, including the coast of Katmai National Park and Preserve in southcentral Alaska. Brown bears are an important component of the Katmai ecosystem where they are the focus of a...

H. Madden, M. Leopold, F. Rivera-Milán, K. Verdel, E. Eggermont, Patrick G.R. Jodice
2022, Waterbirds (45) 39-50
The daily nest-survival rates of Red-billed Tropicbirds (Phaethon aethereus) were estimated over six breeding seasons on St. Eustatius in the Caribbean. We analyzed 338 nesting attempts between 2013 and 2020. The daily survival rate (DSR) of tropicbird nests was modeled as a function of...
Factors affecting post-challenge survival of Flavobacterium psychrophilum in susceptible rainbow trout from the literature
Brian W. Avila, Kathryn P. Huyvaert, Dana L. Winkelman, Eric R. Fetherman
2022, Pathogens (11)
Infectious bacterial pathogens are a concern for aquaculture as estimates suggest that billions of US dollars are lost annually in aquaculture due to disease. One of the most prevalent salmonid pathogens is the bacterium Flavobacterium psychrophilum that causes bacterial coldwater disease. We reviewed the published F. psychrophilum literature and conducted a...

Geologic field-trip guide to volcanism and its interaction with snow and ice at Mount Rainier, Washington
James W. Vallance, Thomas W. Sisson
2022, Scientific Investigations Report 2017-5022-A
Mount Rainier is the Pacific Northwest’s iconic volcano. At 4,393 meters and situated in the south-central Cascade Range of Washington State, it towers over cities of the Puget Lowland. As the highest summit in the Cascade Range, Mount Rainier hosts 26 glaciers and numerous permanent snow fields covering 87 square...
Trends in vegetation and height of the topographic surface in a tidal freshwater swamp experiencing rooting zone saltwater intrusion
Beth Middleton, John L. David
2022, Ecological Applications (145)
A decrease in the ground surface height of coastal wetlands is of worldwide concern because of its relationship to peat loss, coastal carbon, and biodiversity in freshwater wetlands. We asked if it is possible to determine indicators of impending transitions of freshwater swamps to other coastal types by examining long-term...
Effect of uncertainty of discharge data on uncertainty of discharge simulation for the Lake Michigan Diversion, northeastern Illinois and northwestern Indiana
David Soong, Thomas M. Over
2022, Scientific Investigations Report 2022-5102
Simulation models of watershed hydrology (also referred to as “rainfall-runoff models”) are calibrated to the best available streamflow data, which are typically published discharge time series at the outlet of the watershed. Even after calibration, the model generally cannot replicate the published discharges because of simplifications of the physical system...
The 2020 Westmorland, California earthquake swarm as aftershocks of a slow slip event sustained by fluid flow
K. Sirorattanakul, Z.E. Ross, M. Khoshmanesh, Elizabeth S. Cochran, M. Acosta, J.-P. Avouac
2022, Journal of Geophysical Research (127)
Swarms are bursts of earthquakes without an obvious mainshock. Some have been observed to be associated with transient aseismic fault slip, while others are thought to be related to fluids. However, the association is rarely quantitative due to insufficient data quality. We use high-quality GPS/GNSS, InSAR, and...

2022, Conference Paper, Proceedings of the 16th Greenhouse Gas Control Technologies Conference (GHGT-16)
The U.S. Geological Survey (USGS), in conjunction with the U.S. Department of Energy (U.S. DOE) Office of Fossil Energy and Carbon Management (FECM), the IEA Greenhouse Gas R&D Programme (IEAGHG), and the Clean Energy Ministerial Carbon Capture, Utilization and Storage Initiative (CEM-CCUS Initiative), plans to work with partner nations to...
High dispersal rates in hybrids drive expansion of maladaptive hybridization
Samuel Bourret, Ryan P. Kovach, Timothy Joseph Cline, Jeffrey Strait, Clint C. Muhlfeld
2022, Proceedings of the Royal Society B (289)
Hybridization between native and invasive species, a major cause of biodiversity loss, can spread rapidly even when hybrids have reduced fitness. This paradox suggests that hybrids have greater dispersal rates than non-hybridized individuals, yet this mechanism has not been empirically tested in animal populations. Here, we test if non-native genetic...

Marcia N. Snyder, Nathan H. Schumaker, Jason B. Dunham, Joseph L. Ebersole, Mathew L Keefer, Jonathan Halama, Randy L Comeleo, Peter Leinenbach, Allen Brookes, Ben Cope, Jennifer Wu, John Palmer
2022, Ecosphere (13)
The importance of thermal refuges in a rapidly warming world is particularly evident for migratory species, where individuals encounter a wide range of conditions throughout their lives. In this study, we used a spatially explicit, individual-based simulation model to evaluate the buffering potential of cold-water thermal...

Pore systems and organic petrology of cretaceous Mowry and Niobrara source-rock reservoirs, Powder River Basin, Wyoming, USA
Terri Olson, Brad Michalchuk, Paul C. Hackley, Brett J. Valentine, Jason Parker, Ricardo San Martin
2022, International Journal of Coal Geology (264)
The Powder River Basin (PRB) is a world-class oil province, in large part thanks to contributions from premier source rocks, Cretaceous Mowry and Niobrara shales. Both formations are also unconventional reservoirs. A critical aspect of evaluating production potential and finding sweet spots is the nature of the pore systems in these fine-grained...

Laura Anne McDuffie, Katherine S. Christie, Audrey R. Taylor, Erica Nol, Christian Friis, Christopher M. Harwood, Jennie Rausch, Benoit Laliberte, Callie Gesmundo, James R. Wright, James A. Johnson
2022, Ecology and Evolution: Nature Notes (12)
Many populations of long-distance migrant shorebirds are declining rapidly. Since the 1970s, the lesser yellowlegs (Tringa flavipes) has experienced a pronounced reduction in abundance of ~63%. The potential causes of the species' decline are complex and interrelated. Understanding the timing of migration, seasonal routes, and important...
Suspended-sediment transport and water management, Jemez Canyon Dam, New Mexico, 1948–2018
Jeb E. Brown, Anne-Marie Matherne, Justin K. Reale, K. E. Miltenberger
2022, Scientific Investigations Report 2022-5081
Construction and operation of dams provide sources of clean drinking water, support large-scale irrigation, generate hydroelectricity, control floods, and improve river navigation. Yet these benefits are not without cost. Dams affect the natural flow regime, downstream sediment fluxes, and riverine and riparian ecosystems. The Jemez Canyon Dam in New Mexico...

Michael C. Duniway, Christopher Benson, Travis W. Nauman, Anna C. Knight, John B. Bradford, Seth M. Munson, Dana L. Witwicki, Carolyn Livensperger, Matthew W. Van Scoyoc, Terry T Fisk, David Thoma, Mark E. Miller
2022, Ecosphere (13)
Drylands represent more than 41% of the global land surface and are at degradation risk due to land use and climate change. Developing strategies to mitigate degradation and restore drylands in the face of these threats requires an understanding of how drylands are shaped by not only soils and climate,...

Jérôme Le Coz, Emeline Perret, Benoît Camenen, David J. Topping, Daniel D. Buscombe, Kate Leary, Guillaume Dramais, Paul E. Grams
2022, Water Resources Research (58)
This paper introduces a method for determining spatially-distributed, 2-D bedload rates using repeat, high-resolution surveys of the bed topography. As opposed to existing methods, bedform parameters and bedload rates are computed from bed elevation profiles interpolated along the local bedform velocities. The bedform velocity fields are computed...

Drones and bathymetry show the importance of optimal water depth for nest placement within breeding colonies of Western and Clark’s grebes
Deo A. Lachman, Courtney J. Conway, Kerri T. Vierling, Ty Matthews, Diane Evans Mack
2022, Wetlands (42)
Habitat selection involves a series of decisions that are arguably the most important decisions that animals make and these decisions occur at multiple hierarchical spatial scales. Colonial-nesting birds face a unique challenge when selecting a nest site because each bird’s choices are severely constrained by other birds within their breeding...
