Paul E. Bartelt, Peter E. Thornton, Robert W. Klaver
2022, Ecological Indicators (135)
Amphibians are vital elements of ecosystems, serving as predator and prey. Their biphasic nature makes them dependent on aquatic and terrestrial habitats; as wet-skinned ectotherms, they are vulnerable to a range of environmental threats, including climate change. Yellowstone National Park (YNP) is becoming warmer and drier, and some wetlands important...

James R. Holmquist, Lisamarie Windham-Myers
2022, Estuaries and Coasts (45) 1596-1614
Tidal wetlands provide myriad ecosystem services across local to global scales. With their uncertain vulnerability or resilience to rising sea levels, there is a need for mapping flooding drivers and vulnerability proxies for these ecosystems at a national scale. However, tidal wetlands in the conterminous USA are diverse with differing...

Caleb Powell Roberts, Daniel R. Uden, Craig R. Allen, David G. Angeler, Larkin A. Powell, Brady W Allred, Matthew O. Jones, Jeremy D Maestas, Dirac Twidwell
2022, Ecological Indicators (136)
Spatial regimes (the spatial extents of ecological states) exhibit strong spatiotemporal order as they expand or contract in response to retreating or encroaching adjacent spatial regimes (e.g., woody plant invasion of grasslands) and human management (e.g., fire treatments). New methods enable tracking spatial regime boundaries via vegetation landcover data, and...

Scott D. George, Brian T. Duffy, Barry P. Baldigo, Damianos Skaros, Alexander J. Smith
2022, Journal of Great Lakes Research (48) 183-194
The lower 10 km of the Buffalo River, a tributary to Lake Erie, was designated as an Area of Concern (AOC) in 1987 through the Great Lakes Water Quality Agreement because sediment contamination and habitat alteration from past industrialization caused several Beneficial Use Impairments (BUIs). Extensive remediation efforts conducted between 2011 and...

Modeling subsurface performance of a geothermal reservoir using machine learning
Dmitry Duplyakin, Koenraad F Beckers, Drew L. Siler, Michael J. Martin, Henry E. Johnston
2022, Energies (15)
Geothermal power plants typically show decreasing heat and power production rates over time. Mitigation strategies include optimizing the management of existing wells—increasing or decreasing the fluid flow rates across the wells—and drilling new wells at appropriate locations. The latter is expensive, time-consuming, and subject to many engineering...

Christie Hegermiller, John C. Warner, Maitane Olabarrieta, Christopher R. Sherwood, Tarandeep S. Kalra
2022, JGR-Earth Surface (127)
Physical processes driving barrier island change during storms are important to understand to mitigate coastal hazards and to evaluate conceptual models for barrier evolution. Spatial variations in barrier island topography, landcover characteristics, and nearshore and back-barrier hydrodynamics can yield complex morphological change that requires models of increasing resolution and physical...

2022, Earth Surface Processes and Landforms (47) 1466-1479
Ecosystem structure of wetlands in managed floodplains depends on hydrological processes controlled by geomorphology and water management. Overlapping effects of direct modifications and geomorphic adjustments to management can combine to trigger changes to floodplain ecosystem structure. We examined the case of woody vegetation encroaching into the depressional Catahoula Lake, Louisiana,...

Testing the potential of streamflow data to predict spring migration of an ungulate herds
Jason S. Alexander, Marissa L. Murr, Cheryl A. Eddy-Miller
Stefano Grignolio, editor(s)
2022, PLoS ONE (17) 1-18
In mountainous and high latitude regions, migratory animals exploit green waves of emerging vegetation coinciding with rising daily mean temperatures initiating snowmelt across the landscape. Snowmelt also causes rivers and streams draining these regions to swell, a process referred to as to as the ‘spring pulse.’ Networks of streamgages measuring...
