Characterizing fish movements is required for understanding habitat use, energy flow, and trophic structure and can inform fisheries management. Drowned river mouth (DRM) lakes are productive inland habitats in the Laurentian Great Lakes basin used by migratory fishes. Despite recognition of their ecological connections to the Great Lakes, the value...

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...
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, Fact Sheet 2025-3049
Rare earth elements (REEs) are a scarce but vital resource for our modern economies and lifestyles. Since the late 1990s, China has supplied the vast majority of the world’s refined REEs. Increasing global demand has broadened the search for REE deposits to unconventional places, including the Moon. Although most lunar...

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...

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...

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 B. 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...

2025, Climate of the Past (21) 2263-2281
The lack of geological constraints on past ice-sheet change in marine-based sectors of the Greenland Ice Sheet (GrIS) following the Last Glacial Maximum limits our ability to assess (1) the drivers of ice-sheet change, and (2) the performance of ice-sheet models that are benchmarked against the paleo-record of GrIS change....
Cryptic life history diversity supports endangered species recovery in an ultra-urbanized landscape
Shannon L. White, Amanda Higgs, Dewayne Fox
2025, Scientific Reports (15)
Urban landscapes are often overlooked in conservation planning, allowing human activities to take precedence in ecosystem management. However, even heavily modified environments can support diverse species profiles, but continued expansion of the human footprint could transform these biodiversity hotspots into ecological traps that serve as hidden catalysts for demographic declines....

Alma Lizette Anides Morales, Laura M. Norman, Thomas J. Mack
2025, Fact Sheet 2025-3042
The Los Planes watershed of Baja California Sur, Mexico, and its underlying aquifer are experiencing groundwater decline owing to low average annual rainfall (28.1 centimeters per year) and rising water demand from population growth and agricultural activities. This decline in water availability can lead to desertification—a process that changes arable...
