A probabilistic approach to training machine learning models using noisy data
Ayman H. Alzraiee, Richard G. Niswonger
2024, Environmental Modelling & Software (179)
Machine learning (ML) models are increasingly popular in environmental and hydrologic modeling, but they typically contain uncertainties resulting from noisy data (erroneous or outlier data). This paper presents a novel probabilistic approach that combines ML and Markov Chain Monte Carlo simulation to (1) detect and underweight likely noisy data, (2) develop an approach capable of...

2024, Environmental Science and Technology (58) 13205-13216
Perfluorooctane sulfonamide (PFOSA) is an immediate perfluorooctanesulfonate (PFOS) precursor (PreFOS). Previous studies have shown PFOSA to induce stronger toxic responses compared to other perfluorinated compounds (PFCs). However, the specific nature of PFOSA-induced toxicity, whether autonomous or mediated by its metabolite PFOS, has...

John W. Ryter, Karan Bhuwalka, Michelena O’Rourke, Luca Montanelli, David Cohen-Tanugi, Richard Roth, Elsa Olivetti
2024, Journal of Industrial Ecology (28) 709-726
The low-carbon energy transition requires significant increases in production for many mineral commodities. Understanding demand, technological requirements, and prices associated with this production increase requires understanding the supply chain dynamics of many minerals simultaneously, and via a consistent framework. A generalized economics-informed material flow method, global materials modeling using Bayesian...
Integrating ecological value and charismatic species habitats to prioritize habitats for conservation: A case study from Greater Yellowstone
A. J. Hansena, A. Easta, Z. Ashford, C. Crittendena, O. Jakabosky, D. Quinby, Shannon K. Brewer, Frank T. van Manen, Mark A. Haroldson, A. Middleton, N. Robinson, D. M. Theobald
2024, Biological Conservation (44) 157-171
Expanding human pressure has reduced natural habitats globally and motivated strategies to conserve remaining natural habitats. Decisions about conservation on private lands, however, are typically made by local stakeholders who are motivated by the elements of nature they most highly value. Thus, national prioritization...

Turetsky, Mark Waldrop
2024, Journal of Geophysical Research: Biogeosciences (129)
Northern peatlands are a globally significant source of methane (CH4), and emissions are projected to increase due to warming and permafrost loss. Understanding the microbial mechanisms behind patterns in CH4 production in these systems will be key to predicting annual emissions changes, with stable carbon isotopes (δ13C-CH4) being a powerful...

2024, Science of the Total Environment (947)
Global Li production will require a ~500 % increase to meet 2050 projected energy storage demands. One potential source is oil and gas wastewater (i.e., produced water or brine), which naturally has high total dissolved solids (TDS) concentrations, that can also be enriched in Li...
Climate change vulnerability of Arctic char across Scandinavia
Clint C. Muhlfeld, Timothy Cline, Anders Finstad, Dag O. Hessen, Sam Perrin, Jens Thaulow, Diane Whited, Leif Asbjorn Vollestad
2024, Global Change Biology (30)
Climate change is anticipated to cause species to shift their ranges upward and poleward, yet space for tracking suitable habitat conditions may be limited for range-restricted species at the highest elevations and latitudes of the globe. Consequently, range-restricted species inhabiting Arctic freshwater ecosystems, where...
Think regionally, act locally: Perspectives on co-design of spatial conservation prioritization tools and why end-user engagement altered our approach
Nicholas J. Van Lanen, Jessica E. Shyvers, Bryan C. Tarbox, Adrian P. Monroe, Patrick J. Anderson, Daniel K. Jones, Katharine G. Dahm, Cameron L. Aldridge
2024, Conservation Science and Practice (6)
Coproduction represents an inclusive approach for developing decision-support resources because it seeks to integrate scientific knowledge and end-user needs. Unfortunately, spatial decision support systems (SDSS) coproduction has sometimes resulted in limited utility for end-users, partially due to scarce SDSS coproduction guidance. To initiate coproduction, we...

Mangroves’ ability to store carbon (C) has long been recognized, but little is known about whether planted mangroves can store C as efficiently as naturally established (i.e., intact) stands and in which time frame. Through Bayesian logistic models compiled from 40 years of data and built from 684 planted mangrove...
Effects of harmful algal blooms on amphibians and reptiles are under-reported and under-represented
Brian J. Halstead, Kelly Smalling, Blake R. Hossack
2024, Environmental Toxicology and Chemistry (43) 1936-1949
Harmful algal blooms (HABs) are a persistent and increasing problem globally, yet we still have limited knowledge about how they affect wildlife. Although semi-aquatic and aquatic amphibians and reptiles have experienced large declines and occupy environments where HABs are increasingly problematic, their vulnerability to...

Jarrod R. Ludwig, Brian Weidel, Brian O’Malley, Michael Connerton, Jacques Rinchard
2024, Journal of Great Lakes Research (50)
Deepwater sculpin (Myoxocephalus thompsonii) were considered extirpated from Lake Ontario prior to the 1990s but have since resurged and are now an abundant offshore demersal species. As deepwater sculpin reproduction is poorly described, an investigation of their gonadal development and...

Barbara E. Kus, Kristine L. Preston, Alexandra Houston
2024, PLoS ONE (19)
The Coastal California Gnatcatcher (Polioptila californica californica), a federally threatened species, is a flagship species for regional conservation planning in southern California (USA). An inhabitant of coastal sage scrub vegetation, the gnatcatcher has declined in response to habitat loss and fragmentation, exacerbated by catastrophic wildfires. We...
Wood you believe it? Experimental addition of nonnative wood enhances instream habitat for native dryland fishes
Benjamin J. Miller, Mark C. McKinstry, Phaedra E. Budy, Casey A. Pennock
2024, River Research and Applications (40) 1512-1526
Flow alteration and riparian vegetation encroachment are causing habitat simplification with severe consequences for native fishes. To assess the effectiveness of enhancing simplified habitat in a large dryland river, we experimentally added invasive wood at 19 paired treatment and reference (no wood added) subreaches (50–100 m) within the main channel of...
Isotopic evaluation of the National Water Model reveals missing agricultural irrigation contributions to streamflow across the western United States
Annie L. Putman, Patrick C. Longley, Morgan C. McDonnell, James E. Reddy, Michelle P. Katoski, Olivia L. Miller, J. Renee Brooks
2024, Hydrology and Earth Systems Science (28) 2895-2918
The National Water Model (NWM) provides critical analyses and projections of streamflow that support water management decisions. However, the NWM performs poorly in lower-elevation rivers of the western United States (US). The accuracy of the NWM depends on the fidelity of the model inputs and the representation and calibration of...
A fine-scale examination of parturition timing in temperate ungulates
Matthew T. Turnley, Tabitha A. Hughes, Randy T. Larsen, Kent R. Hersey, Matthew S. Broadway, M. Colter Chitwood, W. Sue Fairbanks, Robert Charles Lonsinger, Brock R. McMillan
2024, Functional Ecology (14)
Parturition timing has long been a topic of interest in ungulate research. However, few studies have examined parturition timing at fine scale (e.g., <1 day). Predator activity and environmental conditions can vary considerably with diel timing, which may result in selective pressure for parturition to occur...

S. Alex Covert, G. F. Koltun
2024, Scientific Investigations Report 2024-5045
The U.S. Geological Survey, in cooperation with the Ohio Department of Natural Resources, performed a two-part study to (1) assess water use and temporal trends and changes in streamflow, and to (2) characterize 2021–23 baseline water quality, as they relate to oil and gas extraction activities in selected eastern Ohio...
An integrated analysis for estimation of survival, growth, and movement of unmarked juvenile anadromous fish
Patti J. Wohner, Adam Duarte, James Peterson
2024, Ecological Modelling (495)
Managers invest substantial resources to promote recovery of declining anadromous fish stocks. Recovery strategies are manifold and often include management actions intended to stimulate somatic growth, increase in-river survival, and motivate juvenile outmigration during favorable environmental conditions. Evaluating the efficacy of these management actions is difficult, however, because monitoring data...
