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,...

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...

Estimation of dynamic geologic CO2 storage resources in the Illinois Basin, including effects of brine extraction, anisotropy, and hydrogeologic heterogeneity
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...
Detecting hidden sedimentary geothermal systems in the Upper Colorado River Basin
Rand Gardner, Justin E. Birdwell, Donald S. Sweetkind, Patrick Sullivan, Melia Eaton, Holger Petermann, Annaka Clement, James Hagadorn, Joshua Woda
2025, Conference Paper, Using the Earth to save the Earth
Geothermal resources exist in sedimentary rock where circulation of water for efficient extraction or storage of heat is possible. Except in rare instances where hot water is expressed at the land surface, sedimentary geothermal resources are hidden, so the identification of these systems is optimally accomplished using predictive subsurface modeling....

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...

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...
Geothermal potential of orphan oil and gas wells
Rand Gardner, Justin E. Birdwell, Matthew D. Merrill, Ashton M. Wiens, Karl Haase, Nicholas J. Gianoutsos, Uei I. Lei, Patrick Sullivan
2025, Conference Paper, Using the Earth to save the Earth
The United States is estimated to have hundreds of thousands of orphan oil and gas wells. Orphan wells are abandoned wells that are both unremediated and have no responsible operator. While traditionally considered environmental and economic liabilities, orphan oil and gas wells may offer new opportunities in sustainable geothermal energy...
Preventing overfitting when using tree-based methods for mapping hydrothermal favorability
Stanley Paul Mordensky, Erick R. Burns, John Lipor, Jacob DeAngelo
2025, Conference Paper, Using Earth to save the Earth
Ensemble tree-based algorithms are robust tools for estimating sparsely distributed resources with non-linear dependencies (e.g., hydrothermal systems). These algorithms naturally accommodate the threshold conditions necessary to enable and support hydrothermal systems (e.g., having sufficient heat and permeability) and are simpler than many other non-linear machine learning strategies (e.g., artificial neural...
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...

2025, Conference Paper, Using the Earth to save the Earth
Assessing the potential for geothermal energy and liquid water presence in the Martian subsurface is crucial for future exploration and habitability studies. In this work, we employed comprehensive finite element model simulations adapted specifically for Martian conditions to estimate subsurface temperatures and the potential for liquid water at depth within Martian...
Potential for co-production of lithium and geothermal resources in the Gulf Coast
Rand Gardner, Justin E. Birdwell
2025, Conference Paper, Using the Earth to save the Earth
Lithium brine extractions and geothermal resource developments often are not economically viable as standalone projects, but they May become cost effective when the potential for both resources exist within the same reservoir. Subsurface datasets were analyzed to identify areas in the U.S. Gulf Coast region with potential for lithium brine...
Effects of climate change on Midwestern ecosystems: Central and Eastern North American Grassland and Shrubland
Hugh Ratcliffe, Katherine Charton, Taylor Siddons, Marta P. Lyons, Olivia E. LeDee
2025, Report
The Central and Eastern North American Grassland and Shrubland ecosystem may be increasingly shaped by intensifying drought and shifting seasonality. Rising temperatures and more variable precipitation, marked by longer dry spells, are projected to increase evapotranspiration and soil moisture deficits, and yield more frequent drought. At the same time, warming...
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...

2025, Journal of the Nevada Water Resources Association (2025) 27-40
Fens are groundwater-fed wetlands that can provide habitat for plants and animals. Due to anthropogenic activities and climate change, many fens around the world are at risk. This paper presents the results of a study of the hydrology and geochemistry of fens in Big Smoky Valley, central Nevada to support the...
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...
