Groundwater structures fish growth and production across a riverscape
Jeffrey R. Baldock, Robert Al-Chokhachy, Annika W. Walters
2025, Freshwater Biology (70)
Landscapes are composed of habitat patches and conditions that vary across space and time. While habitat variability and complexity can support important ecological processes and ecosystem services, the dynamic nature of habitats can also constrain organismal growth and production as optimal conditions are fleeting. In riverine ecosystems, groundwater discharge...
When do single-species occupancy models outperform multispecies models?
Gavin G. Cotterill, Douglas A. Keinath, Tabitha A. Graves
2025, Ecology and Evolution (15)
Occupancy models have become increasingly popular for species monitoring and assessment, in part, because detection/non-detection data are readily obtained using a variety of methods. Multispecies occupancy models (MSOMs) can yield more accurate parameter estimates than single-species models (SSOMs) with less data through their hierarchical structure, making MSOMs an attractive option...
Topographic, climatic, and age controls on the reworking of volcanic debris avalanche deposits
Kristin Sweeney, Jon J. Major
2025, Bulletin of Volcanology (87)
Volcanic debris avalanches have deposited as much as 1000 km3 of largely unconsolidated material on landscapes and remodeled existing drainage networks. The landscape disturbances created by these events pose severe, cascading downstream sedimentation hazards that can require long-term societal management, as demonstrated by decades of observations and ongoing...

Divergent responses of seed banks and aboveground vegetation to drought and deluge in grasslands across an elevational gradient
Jennifer R. Gremer, Margaret M. Moore, Daniel C. Laughlin, Seth M. Munson
2025, Oecologia (207)
Increased variability in precipitation associated with climate change creates extreme conditions of drought and deluge that can have profound effects on the abundance and composition of plant communities. Responses to these extremes likely vary across climatic gradients and depend on local plant community composition, which includes the emergent, aboveground vegetation...

Derek W. Ryter, Joseph A. Hevesi, Linda R. Woolfenden
2025, Preprint
The Strawberry Creek watershed, situated in the San Bernardino Mountains of southern California, features a group of natural springs known as Arrowhead Springs that have been augmented with diversions in the form of sub-horizontal borings and tunnels. Understanding the impact of these structures on streamflow through groundwater capture is crucial...
Long‐period ground motions from dynamic rupture simulations of large earthquakes on the creeping Hayward–Calaveras–Rodgers Creek fault system
Ruth A. Harris, Michael Barall, Grace Alexandra Parker, Evan Tyler Hirakawa
2025, Seismological Research Letters
he Hayward, Calaveras, and Rodgers Creek faults in the San Francisco Bay region of California have a high probability of producing a large earthquake in the next decades. Although these faults creep, the creep is insufficient to keep up with their relatively rapid slip rates on their deepest sections, so...
Observations of tear-drinking by lepidopterans on moose (Alces alces americana) in northeastern North America
Laurence A. Clarfeld, Katherina D. Gieder, Therese M. Donovan
2025, Ecosphere (16)
Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the...
Modeling the influence of upper and lower shoreface dynamics on barrier island evolution
Rose Elizabeth Palermo, Jennifer L. Miselis, Daniel J. Ciarletta, Emily A Wei
2025, JGR Earth Surface (130)
Barrier island resilience to climate impacts depends on sediment redistribution between the subaqueous shoreface and subaerial barrier during sea-level rise and storms. However, autogenic interactions between the upper and lower shoreface and their influence on the subaerial barrier are poorly characterized. Here, we explore the influences of various shoreface components...

2025, Oikos
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts. Although substantial research has...
Structural controls on splay fault rupture dynamics during Cascadia megathrust earthquakes
James Burkhardt Biemiller, Alice-Agnes Gabriel, Lydia M. Staisch, Thomas Ulrich, Audrey Dunham, Erin A. Wirth, Janet Watt, Madeleine C. Lucas, Anna Ledeczi
2025, AGU Advances (6)
Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within the accretionary wedge. The mechanics of these shallow rupture phenomena and their dependence on subduction...

Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass (Bromus tectorum), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We aimed to identify mechanisms and consequences of local adaptation in the North American cheatgrass...

Libby M. Wildermuth, Jeffrey R. Kennedy, Jacob L. Conrad
2025, Scientific Investigations Report 2025-5017
Managed aquifer recharge is a widespread practice for storing water in the subsurface as groundwater. At a managed aquifer recharge facility in southern Arizona, groundwater-level and repeat microgravity data were collected to monitor aquifer response. These data were used to inform parameter identification for an unsaturated-zone flow model used to...
Technical note: A low-cost approach to monitoring relative streamflow dynamics in small headwater streams using time lapse imagery and a deep learning model
Phillip J. Goodling, Jennifer H. Fair, Amrita Gupta, Jeffrey D. Walker, Todd Dubreuil, Michael J. Hayden, Benjamin H. Letcher
2025, Hydrology and Earth System Sciences (29) 6445-6460
Despite their ubiquity and importance as freshwater habitat, small headwater streams are under-monitored by existing stream gage networks. To address this gap, we describe a low-cost, non-contact, and low-effort method that enables organizations to monitor relative streamflow dynamics in small headwater streams. The method uses a camera to capture repeat...

Bradley J. Butterfield, Daniel Rodolphe Schlaepfer, Robert Al-Chokhachy, Jason Dunham, Jeremiah D. Groom, Clint C. Muhlfeld, Christian E. Torgersen, John B. Bradford
2025, Ecosphere (16)
Landscapes encompass both aquatic and terrestrial ecosystems that experience the same climate but may respond to climate in divergent ways. For example, the time lag between seasonal dry-down of terrestrial soil moisture and decline in streamflow has important implications for species and ecosystem processes across the aquatic–terrestrial interface. How these...
