A late Cenozoic kinematic model for fault motion within greater Cascadia
Douglas S. Wilson, Patricia A. McCrory
2022, Geochemistry, Geophysics, Geosystems (23)
Widely accepted tectonic reconstructions indicate at least 100 km of coast-parallel northwestward translation of the Sierra Nevada block of California and 15–20° clockwise rotation of most of Oregon since the current phase of Basin and Range extension began ∼17 Ma. These reconstructions require at least 100 km of convergence between the central Coast...
Don't judge an orogen by its cover: Kinematics of the Appalachian décollement from seismic anisotropy
Michael G. Frothingham, Vera Schulte-Pelkum, Kevin H. Mahan, Arthur J. Merschat, Makayla Mather, Zulliet Cabrera Gomez
2022, Geology (50) 1306-1311
As North America collided with Africa to form Pangea during the Alleghanian orogeny, crystalline and sedimentary rocks in the southeastern United States were thrust forelandward along the Appalachian décollement. We examined Ps receiver functions to better constrain the kinematics of this prominent subsurface...
Indicators of fish population responses to avian predation with focus on double-crested cormorants
Douglas W Schultz, Brian S. Dorr, David G. Fielder, James R. Jackson, Robin L. DeBruyne
2022, Journal of Great Lakes Research (48) 1659-1668
Double-crested cormorants (Nannopterum auritum) have been implicated as causes of fish population declines in many locations across their breeding range. Two challenges facing managers are identifying fisheries population metrics indicative of cormorant impacts and determining when this evidence becomes actionable. Building upon existing studies, we conducted a meta-analysis of eight...
Microgravity change during the 2008-2018 Kı̄lauea summit eruption: Nearly a decade of subsurface mass accumulation
Mathijs R. Koymans, Elske de Zeeuw-van Dalfsen, Laslo G. Evers, Michael P. Poland
2022, Journal of Geophysical Research B: Solid Earth (127)
Results from nine microgravity campaigns from Kı̄lauea, Hawaiʻi, spanning most of the volcano's 2008–2018 summit eruption, indicate persistent mass accumulation at shallow levels. A weighted least squares approach is used to recover microgravity results from a network of benchmarks around Kı̄lauea's summit, eliminate instrumental drift, and restore suspected data tares....

2022, Transactions of the American Fisheries Society (151) 611-629
Fish behavior after passage or transfer around dams is a critical component in determining whether the goals of these efforts are achieved, but these behaviors are often poorly understood. An elevator was constructed in the lowermost hydroelectric dam on the Menominee River, Wisconsin–Michigan; it is the first elevator specifically designed...
Over the hills and through the farms: Land use and topography influence genetic connectivity of northern leopard frog (Rana pipiens) in the Prairie Pothole Region
Justin M. Waraniak, David M. Mushet, Craig A. Stockwell
2022, Landscape Ecology (37) 2877-2893
ContextAgricultural land-use conversion has fragmented prairie wetland habitats in the Prairie Pothole Region (PPR), an area with one of the most wetland dense regions in the world. This fragmentation can lead to negative consequences for wetland obligate organisms, heightening risk of local extinction and reducing evolutionary potential for...

Sarah R. Weiskopf, Alexey N. Shiklomanov, Laura Thompson, Sarah Wheedleton, Evan H. Campbell Grant
2022, Diversity and Distributions (28) 2187-2199
AimClimate change is an increasingly important driver of biodiversity loss. The ectothermic nature of amphibians may make them particularly sensitive to changes in temperature and precipitation regimes, adding to declines from other threats. While active season environmental conditions can influence growth and survival, effects of variation in...

2022, Remote Sensing (14)
The lesser prairie-chicken (Tympanuchus pallidicinctus) is a species of prairie grouse that occupies grassland ecosystems in the Southern and Central High Plains of the Great Plains. Reduced abundance and occupied ranges have led to increased conservation efforts throughout the species’ range. Habitat loss is considered the predominant cause of these...

Groundwater quality in selected Stream Valley aquifers, eastern United States
James A. Kingsbury
2022, Fact Sheet 2022-3037
Groundwater provides nearly 50 percent of the Nation’s drinking water. To help protect this vital resource, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are important sources of drinking water (Burow and Belitz, 2014). The stream-valley aquifers constitute one of the important...

Detrital zircon ages from upper Paleozoic–Triassic clastic strata on St. Lawrence Island, Alaska: An enigmatic component of the Arctic Alaska–Chukotka microplate
Jeffrey M. Amato, Julie A. Dumoulin, Eric S. Gottlieb, Thomas E. Moore
2022, Geosphere (18) 1492-1523
New lithologic and detrital zircon (DZ) U-Pb data from Devonian–Triassic strata on St. Lawrence Island in the Bering Sea and from the western Brooks Range of Alaska suggest affinities between these two areas. The Brooks Range constitutes part of the Arctic Alaska–Chukotka microplate, but the tectonic and paleogeographic affinities of...
