Taylor F. Haas, Theodore R. Castro-Santos, Scott M. Miehls, Zhiqun D. Deng, Tyler Michael Bruning, C. Michael Wagner
2023, Animal Biotelemetry (11)
BackgroundLittle is known about the transformer stage of the parasitic lampreys, a brief but critical period that encompasses juvenile out-migration from rivers to lakes or oceans to begin parasitic feeding. Information about this life stage could have significant conservation implications for both imperiled and invasive lampreys. We investigated...

A numerical investigation of the mechanisms controlling salt intrusion in the Delaware Bay Estuary
Salme Ellen Cook, John C. Warner, Kendra L. Russell
2023, Estuarine, Coastal and Shelf Science (283)
Salinity intrusion in coastal systems is mainly controlled by freshwater inflows. However, extreme events like drought, low-pressure storms, and longer-term sea level rise can exacerbate the landward salt migration and threaten economic infrastructure and ecological health. Along the eastern seaboard of the United States, approximately 13 million people rely on the water...

2023, Journal of Environmental Management (342)
The archaeological record documenting human history in deserts is commonly concentrated along rivers in terraces or other landforms built by river sediment deposits. Today that record is at risk in many river valleys owing to human resource and infrastructure development activities, including the construction and operation of dams. We assessed...

Megan K. Schall, Geoffrey Smith, Vicki S. Blazer, Heather L. Walsh, Timothy Wertz, Dustin R. Shull, Tyler Wagner
2023, Fisheries Magazine (48) 287-294
Managing and understanding fisheries dynamics are becoming more complex as new and seemingly more complicated environmental factors are identified. Often management requires resources beyond that of any one entity and calls for collaboration among partners with differing priorities and backgrounds to account for the complexity of factors influencing fisheries. We...

Unzipping supercontinent Pangea: Geologic, potential field data, and buried structures, and a case for sequential Atlantic opening
Aaron G. Stubblefield, Robert D. Hatcher, J. Wright Horton, Jr., David L. Daniels
2023, Tectonophysics (856) 229842 (1-10 online)
Amalgamation of Pangea culminated with zippered N-to-S closing of the Theic ocean during the Alleghanian orogeny. Transpressional-rotational collision produced widespread dextral faulting throughout the eastern Appalachian hinterland, and thrust faulting in the western hinterland and foreland. The partially buried southern...

Policymakers must make management decisions despite incomplete knowledge and conflicting model projections. Little guidance exists for the rapid, representative, and unbiased collection of policy-relevant scientific input from independent modeling teams. Integrating approaches from decision analysis, expert judgment, and model aggregation, we convened multiple modeling teams to evaluate COVID-19 reopening strategies...

Mark W. Carter, Ryan J. McAleer, Christopher S. Holm-Denoma, Marcie E. Occhi, Brent E. Owens, Jorge A. Vazquez
2023, Geosphere (19) 900-932
Field relations as well as geochemical and petrologic studies of metaigneous rocks assigned to the Pennsylvanian–Permian Petersburg batholith identify at least two distinct rock types: foliated metagranitoid gneiss and massive to porphyritic granite. Foliated metagranitoid gneiss of mostly granodioritic composition is geochemically distinct from associated massive and porphyritic granitic rocks....
Karst terrain promotes thermal resiliency in headwater streams
Karmann G. Kessler, Karli M. Rogers, Charles Marshak, Nathaniel P. Hitt
2023, Conference Paper, Proceedings of the West Virginia Academy of Science
The response of stream ecosystems to climate change will depend in part on groundwater processes that reduce the sensitivity of streams to atmospheric conditions. We investigated the thermal sensitivity of streams across a gradient of groundwater inputs defined by karst terrain (carbonate parent materials) in the headwaters of the Potomac...
