River ice controls permafrost bank erosion across an Arctic delta
J Arcuri, Irina Overeem, Marisa Repasch, R. S. Anderson, S. P. Anderson, Joshua C. Koch, Frank Urban
2025, Earth Surface Processes and Landforms (50)
Bank erosion in Arctic rivers helps shape channel geometry, mobilizes carbon from permafrost and influences sediment delivery to the Arctic Ocean. On Alaska's Arctic coastal plain, rivers begin flowing during snowmelt in late spring while extensive river ice persists in channels, such that hydraulics are altered and water is kept...

Ian Robert Reeves, Andrew D. Ashton, Erika E. Lentz, Christopher R. Sherwood, Davina Passeri, Sara Zeigler
2025, Geoscientific Model Development (18) 9319-9348
Models of coastal barrier geomorphic and ecologic change are valuable tools for understanding and predicting when, where, and how barriers evolve and transition between ecogeomorphic states. Few existing models of barrier systems are designed to operate over spatiotemporal scales congruous with effective management practices (i.e., decades/kilometers, referred to herein as...
Summary of first daily ring formation in otoliths of freshwater fishes in the continental United States
James M. Long, Richard A. Snow
2025, Fisheries
Daily ring counts in young-of-the-year fishes are important for estimating important vital rates, such as growth, mortality, and timing of hatch. To accurately estimate some of these rates, the timing of the first daily ring must be estimated accurately. Variation in the timing of the first daily ring...

2025, Society and Natural Resources
Chronic Wasting Disease (CWD) is a fatal and contagious neurological disease of cervid populations across North America. Collaborative efforts between government agencies, researchers, policymakers, and stakeholders are necessary to minimize CWD prevalence, spread, and impacts on animal and human health and well-being. However, critical information related to CWD epidemiology, management,...

Amy Kristine Wray, Bradley James Udell, Helen Trice Davis, Richard D. Inman, Bennet Thomas Lohre, Haley Breiann Price, Jonathan D. Reichard, Andrea Nichole Schuhmann, Bethany Straw, Frank Charles Tousley, Jill Utrup, Ashton M. Wiens, Brian Reichert
2025, Journal of North American Bat Research (3) 1-18
Historically, Myotis septentrionalis (Northern Long eared Bat) was among the most common forest-interior species in North America. Largely due to high mortality from white-nose syndrome, this species has experienced severe population declines across its range. To create an updated species distribution map representing summer occupancy probabilities from 2017 to 2022, we integrated...

Michelle R. Plampin, Steven T. Anderson, Stefan Finsterle, Ashton M. Wiens
2025, Frontiers in Earth Science (13)
Since the vast majority of carbon dioxide (CO2) storage resources in the United States are in deep saline aquifers, optimizing the use of these saline storage resources could be crucial for efficient development of geologic CO2 storage (GCS) resources and basin- or larger-scale deployment of GCS in the country. Maximum CO2 injection...

Noah Hunt, Chauncey K. Asing, Lindsey Nietmann, Paul C. Banko, Richard J. Camp
2025, Avian Conservation and Ecology (20)
Palila (Loxioides bailleui) are critically endangered Hawaiian honeycreepers specializing on māmane (Sophora chrysophylla) seeds and restricted to Mauna Kea volcano on the Island of Hawaiʻi. Recently, the population was estimated to decline by 89% between 1998 and 2021, despite decades of ungulate removal, fence construction, māmane regeneration, fire suppression, and...

Caitlin Beaver, Alexis B. Tays, Wilfre Fuentes Santos, Madison E.A. Harman, Kristen A. Ewen, Evan L. Gwilliam, Margaret Hunter
2025, Science Report NPS/SR—2025/367
Invasive Central American boas (Boa imperator) have established a reproducing population on the western side of St. Croix, U.S. Virgin Islands but prevalence throughout the island is largely unknown. The large snakes threaten endemic and endangered species through competition and predation, jeopardizing island biodiversity. Environmental DNA (eDNA) methods were used...
Pre-eruptive characteristics of “suspect” silicic magmas in Carlin-type Au-forming systems
Celestine N. Mercer, Julie Roberge, Regina Marie Khoury, Albert H. Hofstra
2025, American Mineralogist (110) 1898-1918
World-class Carlin-type Au deposits hosted in sedimentary rock were formed when profuse Eocene silicic magmatism swept across northern Nevada in response to arc migration. Carlin-type Au deposits formed along with porphyry/skarn Cu-Mo-W-Au deposits, epithermal Ag-Au deposits, and distal disseminated Ag-Au deposits. But unlike these other Au-bearing deposits that have clear...
Predicting niche spaces of expanding Evening Bat (Nycticeius humeralis) populations following white-nose syndrome establishment
Sally B. Martinez, Laura D’Acunto, Bradford J. Westrich, Scott M. Bergeson, Patrick A. Zollner
2025, Journal of Mammalogy
Observations of the Evening Bat (Nycticeius humeralis), a species historically distributed abundantly throughout the southeastern United States, are speculated to have increased in the Midwest. One hypothesis for this expansion in geographic distribution is that local extirpations of other bat species resulted in the expanded realized niche spaces for evening...
Leveraging an observed-data likelihood improves the use of machine learning labels in a Bayesian hierarchical model for bioacoustic data
Jacob Oram, Katharine M. Banner, Christian Stratton, Andrew Hoegh, Kathryn Irvine
2025, Annals of Applied Statistics (19) 2957-2980
Classification of massive datasets by machine learning (ML) algorithms is promising for many scientific domains, especially wildlife monitoring programs that rely on passive acoustic surveys for detecting species. However, treating ML-predicted class labels (e.g., species identity) as truth biases inferences of focal parameters within common modeling frameworks. One solution is...

2025, Wildlife Society Bulletin (49)
Wildlife agencies collect data on productivity (e.g., proportion of hens with poults and number of poults per hen) of wild turkey (Meleagris gallopavo) to monitor population status and trends. However, sampling protocols to collect productivity data rely on opportunistic observations reported by wildlife agency personnel and the...

2025, Earth Surface Processes and Landforms (50)
Sources, transport mechanisms and pathways of fine sediment in river systems are dependent on a multitude of climatic, geomorphic and anthropogenic factors, resulting in geomorphic equifinality, in which it is difficult to parse how different landscape processes affect sediment transport across different spatiotemporal scales. The objectives of this study are...
Rare milkvetch (Astragalus) persistence at a utility-scale solar energy facility in the Mojave Desert
Tiffany J. Pereira, Claire C Karban, Lara A. Kobelt, Seth Munson
2025, Frontiers in Ecology and Evolution (13)
Utility-scale solar energy (USSE) development is driving the projected growth in global renewable energy capacity but comes with environmental tradeoffs. New, alternative construction methods are promoted to minimize impacts to soils, vegetation, and hydrology; however, the disturbance created by these methods requires further investigation. We evaluated the population of a...
The effects of carnivory and herbivory on the energy balance of Arctic grizzly bears
Anthony M. Pagano, Karyn D. Rode, Kerry L. Nicholson, William B. Leacock, Craig A. Stricker, Charles T. Robbins
2025, Oecologia (208)
Omnivores often face tradeoffs between selecting for spatially dispersed energy-dense vertebrate prey versus densely distributed herbivorous resources that have limited energetic value per unit intake. Arctic grizzly bears (Ursus arctos) are large omnivores within a resource-limited ecosystem that are known to exhibit smaller body masses and occur at lower densities...
Summer snow determines the depth to ice-cemented ground under dry permafrost in Antarctica
C. P. McKay, M. Marinova, Kaj E. Williams, M. Mellon
2025, Antarctic Science
Dry permafrost underlain by ice-cemented permafrost has been reported in several locations in Antarctica. Initially thought to be relic ice, it is now understood that this subsurface ice is in equilibrium with the surface conditions, although it is not in equilibrium with the atmosphere. We use year-round data from University...
