A riverscape approach reveals downstream propagation of stream thermal responses to riparian thinning at multiple scales
David A. Roon, Jason B. Dunham, Christian E. Torgersen
2021, Ecosphere (12)
Hydrological connectivity in river networks influences their response to environmental changes as local effects may extend downstream via flowing water. For example, localized changes in riparian forest conditions can affect stream temperatures, and these effects may propagate downstream. However, studies evaluating stream temperature responses to riparian forest management have not...

STEPS: Slip time earthquake path simulations applied to the San Andreas and Toe Jam Hill Faults to redefine geologic slip rate uncertainty
Alexandra Elise Hatem, Ryan D. Gold, Richard W. Briggs, Katherine M. Scharer, Edward H. Field
2021, Geochemistry, Geophysics, Geosystems (10)
Geologic slip rates are a time-averaged measurement of fault displacement calculated over hundreds to million-year time scales and are a primary input for probabilistic seismic hazard analyses, which forecast expected ground shaking in future earthquakes. Despite their utility for seismic hazard calculations, longer-term geologic slip rates represent...

Ivonne Cassaigne, Ron W. Thompson, Rodrigo A. Medellin, Melanie Culver, Alexander Ochoa, Karla Vargas, Jack L. Childs, Manuel Galaz, Jim Sanderson
2021, Southwestern Naturalist (65) 123-130
Retaliatory killing of large carnivores due to livestock predation is one of the major threats for the conservation of many declining populations of predators. According to empirical observations, there is a higher incidence of livestock predation when native prey abundance is low. In this study, we applied a treatment consisting...

Sarfaraz Alam, Mekonnen Gebremichael, Zhaoxin Ban, Bridget R. Scanlon, Gabriel B. Senay, D. P. Lettenmaier
2021, Water Resources Research (57)
Groundwater depletion is a major threat to agricultural and municipal water supply in California's Central Valley. Recent droughts during 2007–2009 and 2012–2016 exacerbated chronic groundwater depletion. However, it is unclear how much groundwater storage recovered from drought-related overdrafts during post-drought years, and how climatic conditions and water...

John J. Lyons, Hannah R. Dietterich, Matthew R. Patrick, David Fee
2021, Bulletin of Volcanology (83)
The 2018 eruption of Kīlauea Volcano produced large and destructive lava flows from the fissure 8 (Ahu ‘aila ‘au) vent with flow velocities up to 17 m s−1, highly variable effusion rates over both short (minutes) and long (hours) time scales, and a proximal channel or spillway that...
Complex vulnerabilities of the water and aquatic carbon cycles to permafrost thaw
Michelle A. Walvoord, Robert G. Striegl
2021, Frontiers in Climate (3)
The spatial distribution and depth of permafrost are changing in response to warming and landscape disturbance across northern Arctic and boreal regions. This alters the infiltration, flow, surface and subsurface distribution, and hydrologic connectivity of inland waters. Such changes in the water cycle consequently alter the source, transport, and biogeochemical...

Use of non-lethal endpoints to establish water quality requirements and optima of the endangered Topeka shiner (Notropis topeka)
Amanda E. Rosenberger, Rory T. Mott
2021, Environmental Biology of Fishes (104) 1215-1233
Water quality standards based on sub-lethal effects and performance optima for aquatic organisms, rather than onset of mortality, are more ecologically relevant for management of species of conservation concern. We investigated the effects of hypoxia, temperature (with acclimation), nitrogenous chemical compounds, and chloride on Topeka shiners (Notropis topeka) by monitoring...
