The diversity of influenza A viruses (IAV) is primarily hosted by two highly divergent avian orders: Anseriformes (ducks, swans and geese) and Charadriiformes (gulls, terns and shorebirds). Studies of IAV have historically focused on Anseriformes, specifically dabbling ducks, overlooking the diversity of hosts in nature, including...

Changes in waterfowl migration phenologies in central North America: Implications for future waterfowl conservation
Kent Andersson, Craig A. Davis, Grant Harris, David A. Haukos
2022, PLoS ONE (17)
Globally, migration phenologies of numerous avian species have shifted over the past half-century. Despite North American waterfowl being well researched, published data on shifts in waterfowl migration phenologies remain scarce. Understanding shifts in waterfowl migration phenologies along with potential drivers is critical for guiding future conservation efforts. Therefore, we utilized...

Susan M. Karl, Douglas C. Kreiner, George N.D. Case, Keith A. Labay
2022, Fact Sheet 2022-3008
Comprehensive, data-driven geographic information system analyses utilize publicly available lithologic, geochemical, geophysical, and mineral occurrence datasets to delineate gold resource potential in Alaska. These prospectivity analyses successfully identify areas containing known lode gold occurrences, expand areas of high prospectivity around known occurrences, improve the precision of delineation of areas of...
Variation of cisco egg size among Laurentian Great Lakes populations
Scott T Koenigbauer, Daniel L. Yule, Kristopher Dey, Chris Olds, Michael J. Connerton, Tomas O Hook
2022, Journal of Great Lakes Research (48) 790-797
Many fish species display inter-population and inter-individual egg size variation. Intra-specific differences in egg size seemingly reflect both energetic experiences of individual spawning fish and long-term population responses to differing ecosystems. Optimal egg size theory implies that selection influences a population’s mean egg size in response to its early-life environment,...

Combining process-based and data-driven approaches to forecast beach and dune change
Michael Itzkin, Laura J. Moore, Peter Ruggiero, Paige A. Hovenga, Sally D. Hacker
2022, Environmental Modelling & Software (153)
Producing accurate hindcasts and forecasts with coupled models is challenging due to complex parameterizations that are difficult to ground in observational data. We present a calibration workflow that utilizes a series of machine learning algorithms paired with Windsurf, a coupled beach-dune model (Aeolis, the Coastal Dune Model, and XBeach), to produce hindcasts and forecasts of...
Hot spots and hot moments in the Critical Zone: Identification of and incorporation into reactive transport models
Bhavna Arora, Martin Briggs, Jay P. Zarnetske, James Stegen, Jesus Gomez-Velez, D. Dwivedi
2022, Book chapter, Biogeochemistry of the Critical Zone
Biogeochemical processes are often spatially discrete (hot spots) and temporally isolated (hot moments) due to variability in controlling factors like hydrologic fluxes, lithological characteristics, bio-geomorphic features, and external forcing. Although these hot spots and hot moments (HSHMs) account for a high percentage of carbon, nitrogen and nutrient cycling within the...
Velocity modeling of supercritical pore fluids through porous media under reservoir conditions with applications for petroleum secondary migration and carbon sequestration plumes
Lauri A. Burke
2022, SEG-AAPG Interpretation (10) SG1-SG9
Computational methods to characterize secondary migration in porous media traditionally rely on fluid transport equations with assumptions of time invariance, such as flowpath modeling of buoyancy vectors, statistical percolation algorithms, capillary pressure curves, or a form of Darcy’s Law which presumes instantaneous fluid transport. However, in petroleum systems modeling, the...

Rodriguez-Caballero, T Stanelle, S Egerer, Yang Cheng, H. E. Suess, Y Canton, Jayne Belnap, M O Andreae, I Tegen, C Reick, Ulrich Poschl, B. Weber
2022, Nature Geoscience (15) 458-463
Biological soil crusts (biocrusts) cover ~12% of the global land surface. They are formed by an intimate association between soil particles, photoautotrophic and heterotrophic organisms, and they effectively stabilize the soil surface of drylands. Quantitative information on the impact of biocrusts on the global cycling and climate effects of aeolian...

Friction in clay-bearing faults increases with the ionic radius of interlayer cations
Hiroshi Sakuma, David A. Lockner, John Solum, Nick Davatzes
2022, Communications Earth & Environment (3)
Smectite can dramatically reduce the strength of crustal faults and may cause creep on natural faults without great earthquakes; however, the frictional mechanism remains unexplained. Here, our shear experiments reveal systematic increase in shear strength with the increase of the ionic radius of interlayer cations among...
