The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are time-consuming and expensive to produce, creating potential barriers to adoption in data- and funding-poor regions. Recently released pre-trained avian acoustic classification models provide opportunities to reduce the need for manual labelling and accelerate the development of new acoustic classification algorithms through transfer learning. Transfer learning is a strategy for developing algorithms under data scarcity that uses pre-trained models from related tasks to adapt to new tasks.</p><p>2. Our primary objective was to develop a transfer learning strategy using the feature embeddings of a pre-trained avian classification model to train custom acoustic classification models in data-scarce contexts. We used three annotated avian acoustic datasets to test whether transfer learning and soundscape simulation-based data augmentation could substantially reduce the annotated training data necessary to develop performant custom acoustic classifiers. We also conducted a sensitivity analysis for hyperparameter choice and model architecture. We then assessed the generalizability of our strategy to increasingly novel non-avian classification tasks.</p><p>3. With as few as two training examples per class, our soundscape simulation data augmentation approach consistently yielded new classifiers with improved performance relative to the pre-trained classification model and transfer learning classifiers trained with other augmentation approaches. Performance increases were evident for three avian test datasets, including single-class and multi-label contexts. We observed that the relative performance among our data augmentation approaches varied for the avian datasets and nearly converged for one dataset when we included more training examples.</p><p>4. We demonstrate an efficient approach to developing new acoustic classifiers leveraging open-source sound repositories and pre-trained networks to reduce manual labelling. With very few examples, our soundscape simulation approach to data augmentation yielded classifiers with performance equivalent to those trained with many more examples, showing it is possible to reduce manual label-ling while still achieving high-performance classifiers and, in turn, expanding the potential for passive acoustic monitoring to address rising biodiversity monitoring needs.</p>","language":"English","publisher":"British Ecological Society","doi":"10.1111/2041-210X.70089","usgsCitation":"Weldy, M.J., Lesmeister, D.B., Denton, T., Duarte, A., Vernasco, B.J., Gasc, A., Rowe, J., Adams, M.J., and Betts, M., 2026, Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity: Methods in Ecology and Evolution, v. 17, no. 2, p. 322-338, https://doi.org/10.1111/2041-210X.70089.","productDescription":"17 p.","startPage":"322","endPage":"338","ipdsId":"IP-169596","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":491718,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/2041-210x.70089","text":"Publisher Index Page"},{"id":491528,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationDate":"2025-06-26","publicationStatus":"PW","contributors":{"authors":[{"text":"Weldy, Matthew J","contributorId":300545,"corporation":false,"usgs":false,"family":"Weldy","given":"Matthew","email":"","middleInitial":"J","affiliations":[{"id":65191,"text":"Pacific Northwest Research Station, USDA Forest Service, Corvallis, OR 97331, USA; Department of Forest Ecosystems and Society, Oregon State University, Corvallis, OR 97331, USA","active":true,"usgs":false}],"preferred":false,"id":941424,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lesmeister, Damon B. 0000-0003-1102-0122","orcid":"https://orcid.org/0000-0003-1102-0122","contributorId":205006,"corporation":false,"usgs":false,"family":"Lesmeister","given":"Damon","email":"","middleInitial":"B.","affiliations":[{"id":37019,"text":"USDA Forest Service, Pacific Northwest Research Station","active":true,"usgs":false}],"preferred":false,"id":941425,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Denton, Tom 0000-0003-3866-0031","orcid":"https://orcid.org/0000-0003-3866-0031","contributorId":351479,"corporation":false,"usgs":false,"family":"Denton","given":"Tom","affiliations":[{"id":83995,"text":"Google Deepmind, Google","active":true,"usgs":false}],"preferred":false,"id":941426,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Duarte, Adam","contributorId":337608,"corporation":false,"usgs":false,"family":"Duarte","given":"Adam","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":941427,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Vernasco, Ben J.","contributorId":166945,"corporation":false,"usgs":false,"family":"Vernasco","given":"Ben","email":"","middleInitial":"J.","affiliations":[{"id":24577,"text":"University of Minnesota, St. Paul, MN","active":true,"usgs":false}],"preferred":false,"id":941428,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gasc, Amandine 0000-0001-8369-4930","orcid":"https://orcid.org/0000-0001-8369-4930","contributorId":357451,"corporation":false,"usgs":false,"family":"Gasc","given":"Amandine","affiliations":[{"id":85421,"text":"Institut Méditerranéen de Biodiversité et d'Ecologie marine et continentale","active":true,"usgs":false}],"preferred":false,"id":941429,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rowe, Jennifer 0000-0002-5253-2223 jrowe@usgs.gov","orcid":"https://orcid.org/0000-0002-5253-2223","contributorId":172670,"corporation":false,"usgs":true,"family":"Rowe","given":"Jennifer","email":"jrowe@usgs.gov","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":941430,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Adams, Michael J. 0000-0001-8844-042X","orcid":"https://orcid.org/0000-0001-8844-042X","contributorId":211916,"corporation":false,"usgs":true,"family":"Adams","given":"Michael","email":"","middleInitial":"J.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":true,"id":941431,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Betts, Matthew G.","contributorId":340630,"corporation":false,"usgs":false,"family":"Betts","given":"Matthew G.","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":941432,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Unlike most igneous rocks composed of silicate minerals, carbonatites are dominated by carbonate minerals, some of which can incorporate significant light REEs (LREEs; La, Ce, Pr, Nd). Technological applications of REEs are numerous and they have been identified as some of the most critical mineral commodities to the global economy. The Mountain Pass carbonatite stock in the Mojave Desert of California is the most economically significant REE deposit in the USA and contains a few to tens of percent (by volume) of the carbonate REE ore mineral bastnäsite. Despite the economic significance of the Mountain Pass deposit, studies of its ore mineralogy are limited. Here we present new carbonate ore mineralogy data for a compositionally diverse suite of carbonatitic rocks from the Mountain Pass stock and related dikes. Whole-rock geochemical data are integrated with mineral-scale textural and chemical data obtained by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and microRaman spectroscopy. Our results document a complex spectrum of REE-bearing carbonate minerals and intermediate mixed-layer structures. Mineral species include bastnäsite [REE(CO</span><sub>3</sub><span>)F], hydroxylbastnäsite [REE(CO</span><sub>3</sub><span>)OH], parisite [Ca(REE)</span><sub>2</sub><span>(CO</span><sub>3</sub><span>)</span><sub>3</sub><span>F</span><sub>2</sub><span>], synchysite [Ca(REE)(CO</span><sub>3</sub><span>)</span><sub>2</sub><span>F], röntgenite [Ca</span><sub>2</sub><span>(Ce,La)</span><sub>3</sub><span>(CO</span><sub>3</sub><span>)</span><sub>5</sub><span>F</span><sub>3</sub><span>], and sahamalite [(Mg,Fe</span><sup>2+</sup><span>)(REE)</span><sub>2</sub><span>(CO</span><sub>3</sub><span>)</span><sub>4</sub><span>]. Carbonate ore mineralogy is heterogeneous within and between samples, including at the intracrystal scale. Complexly zoned crystals exhibit as many as five to six different compositional domains and syntaxial intergrowths, commonly with the more Ca-rich varieties (parisite, synchysite) forming crystal rims that surround relict bastnäsite cores. We attribute the phenocryst variability to changes in the chemistry and temperature of primary carbonatite magmas and evolved/exsolved fluids. Cross-cutting vein textures of calcite, celestine and various REE carbonate minerals, interstitial bastnäsite crystallization, breccia blocks lined by fine-grained bastnäsite, and the presence of hydroxylbastnäsite and partially hydroxylated bastnäsite point to the role of secondary hydrothermal processes in REE mineralization. Fluorcarbonate mineral compositions demonstrate that La and Ce are more structurally abundant in bastnäsite, whereas the more Ca-rich species (parisite, synchysite) contain a greater proportion of REE heavier than Pr (Nd, Sm, Eu, Gd) and Y. Atomic ratios of Pr/(Nd + Pr) are likewise variable, with the highest average value for bastnäsite (0.25) compared to parisite (0.22) and sychysite (0.21). This finding has geometallurgical implications, given that current mining operations are focused on recovery of Nd and Pr for high field strength permanent magnets and the Nd/Pr ratios are a critical factor in ore processing and magnet manufacture.</span></p>","language":"English","publisher":"Mineralogical Society of America","doi":"10.2138/am-2025-9822","usgsCitation":"Watts, K., and Andersen, A.K., 2026, Complex carbonate ore mineralogy in the Mountain Pass carbonatite rare earth element deposit, USA: American Mineralogist, v. 111, no. 1, p. 11-28, https://doi.org/10.2138/am-2025-9822.","productDescription":"18 p.","startPage":"11","endPage":"28","ipdsId":"IP-177044","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":491816,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Mojave Desert","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.7207777205175,\n              34.770376743385455\n            ],\n            [\n              -116.7207777205175,\n              33.763579479875446\n            ],\n            [\n              -114.52759201972991,\n              33.763579479875446\n            ],\n            [\n              -114.52759201972991,\n              34.770376743385455\n            ],\n            [\n              -116.7207777205175,\n              34.770376743385455\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"111","issue":"1","noUsgsAuthors":false,"publicationDate":"2026-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Watts, Kathryn E. 0000-0002-6110-7499","orcid":"https://orcid.org/0000-0002-6110-7499","contributorId":204344,"corporation":false,"usgs":true,"family":"Watts","given":"Kathryn E.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":942029,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andersen, Allen K. 0000-0002-6865-2561","orcid":"https://orcid.org/0000-0002-6865-2561","contributorId":217476,"corporation":false,"usgs":true,"family":"Andersen","given":"Allen","email":"","middleInitial":"K.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":942030,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These predictions, however, are valuable for decision makers tasked with managing species and determining their legal status. We applied a spatially explicit projection model to estimate population growth and viability of gray wolves (</span><i>Canis lupus</i><span>) from 2021 to 2070 in the state of Washington, USA, where wolves have been naturally recolonizing since the establishment of the first resident pack in 2008. Using this model, we predicted the effects of 12 scenarios relating to management actions (e.g., lethal removals by the state agency, translocation, recreational harvest) and system uncertainties (e.g., immigration from out of state, disease) on the probability of meeting Washington's wolf recovery goals, the probability of extinction, and other metrics related to population status. Population recovery was defined under Washington's Wolf Conservation and Management Plan as four breeding pairs in each of three recovery regions and three additional breeding pairs anywhere in the state. The baseline and two translocation scenarios indicated a high (&gt; 90%) probability of wolf recovery in Washington by 2070, but scenarios related to harvest mortality (removal of 5% of the population every 6 months), increased lethal removals (removal of 8.53% of the population across the state each year), and cessation of immigration from out of state resulted in probabilities of &lt; 0.20 (0.01, 0.04, and 0.17, respectively) of meeting recovery goals by 2070. Only two scenarios of 12 (increased harvest and lethal removals scenarios) resulted in a geometric mean of population growth ≤ 1, indicating long-term population stability or growth for most scenarios. Our results suggest that wolves will continue to recolonize Washington and that recovery goals are likely to be met so long as harvest and lethal removals are not at unsustainable levels and adjacent populations support immigration into Washington.</span></p>","language":"English","publisher":"Zoological Society of London","doi":"10.1111/acv.70019","usgsCitation":"Petracca, L.S., Converse, S.J.,

To estimate downstream areas where freshwater mussels might face threats from sediment burial within the mussel habitats of Missouri streams and rivers, we examined 49 reaches where both field measurements and gaging data are available. We established empirical relationships for three flow classes to represent general flow conditions of all reaches. Using these hydraulic data, we employed a Lagrangian particle tracking model to simulate sediment transport under each condition, employing two sediment size ranges covering very fine sands to small gravels, resulting in 72 simulated scenarios. The model results indicate that sediments with diameters exceeding a critical value, ranging from 0.041 to 1.975 mm for varying velocities (ranging from 0.124 to 2.191 m/s) and depths (ranging from 1 to 12 m), settle in downstream locations. Potential settling sites span from tens to hundreds of meters downstream. The mode, median, and mean of sediment distribution generally fall within the range of 10–200 m based on particle count, while these values typically range from 1 to 100 m based on sediment mass.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/24705357.2025.2462298","usgsCitation":"Sun, Q., Wang, B., Sansom, B.J., Trauth, K., Brown, H., Zhu, W., Kunz, J.L.,

The most common hazard is one of collision, and this paper will look at problems with glass in buildings, power lines, and wind turbines all as sources of collision and trauma to avian wildlife. However, other anthropogenic factors that can adversely affect avian wildlife can be those that effectively eliminate suitable habitat for avian wildlife. These can include noise factors associated with such things as wind turbines and construction areas and the loss of habitat to large solar arrays, not to mention strip mining for coal and oil-sands. All these factors can contribute to the estimated loss of 3 billion birds in the last five decades.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Current therapy in avian medicine and surgery","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Elsiever","doi":"10.1016/B978-0-323-69484-1.00059-7","usgsCitation":"Olsen, G.H., 2026, Hazards related to man-made structures: Buildings, noise, electric power, chap. 50 <i>of</i> Current therapy in avian medicine and surgery, v.

The shelf-incised head of Astoria Canyon receives sediment from the nearby Columbia River and is subject to energetic forcing from shelf and slope processes, making it an ideal site to evaluate the modern activity of canyons in high-stand sea level conditions. This study uses in-situ data from Astoria Canyon to identify the active&nbsp;sediment transport&nbsp;processes and patterns of accumulation in temperate canyon systems that are decoupled from their sediment sources during sea level highstand. Hydrodynamic data from a benthic tripod deployment in the head of Astoria Canyon shows that sediment&nbsp;resuspension&nbsp;and transport during summer is driven by internal tides and plume-associated nonlinear internal waves. Observations of shoreward-directed currents and low shear stresses (&lt;0.14&nbsp;Pa) along with&nbsp;sediment trap&nbsp;data suggest that seasonal loading of the canyon head occurs during summer. Nearby long-term wave data show that winter storm&nbsp;significant wave height&nbsp;often exceeds 10&nbsp;m, driving shear stress capable of resuspending all grain sizes present within the canyon head. Swell events are generally concurrent with&nbsp;downwelling&nbsp;flows, providing a mechanism for episodic downcanyon sediment flux.

Species radiations established by long-distance, and especially transoceanic, dispersal can cause substantial shifts in regional biodiversity. Here, we investigate the occurrence and timing of the greatest known long-distance oceanic dispersal event in the history of terrestrial vertebrates—the rafting of iguanas from North America to Fiji. Iguanas are large-bodied herbivores that are well-known overwater dispersers, including species that colonized the Caribbean and the Galápagos islands. However, the origin of Fijian iguanas had not been comprehensively tested. We estimated the phylogenetic relationships and evolutionary timescale of the iguanid lizard radiation using genome-wide exons and ultraconserved elements (UCEs). Those data indicate that the closest living relative of extant Fijian iguanas is the North American desert iguana and that the two taxa likely diverged during the late Paleogene near or after the onset of volcanism that produced the Fijian archipelago. Biogeographic models estimate North America as the most probable ancestral range of Fijian iguanas. Our analyses support the hypothesis that iguanas reached Fiji via an extraordinary oceanic dispersal event from western North America, and which spanned a fifth of the earth’s circumference (&gt;8,000 km). Overwater rafting of iguanas from North America to Fiji strengthens the importance of founder-event speciation in the diversification of iguanids and elucidates the scope of long-distance dispersal across terrestrial vertebrates.</span></p>","language":"English","publisher":"National Academy of Sciences","doi":"10.1073/pnas.2318622122","usgsCitation":"Scarpetta, S.G., Fisher, R.D., Karin, B.R., Niukula, J.B., Corl, A., Jackman, T.R., and McGuire, J.A., 2026, Iguanas rafted more than 8,000 km from North America to Fiji: Proceedings of the National Academy of Sciences, v. 122, no. 12, e2318622122, 10 p., https://doi.org/10.1073/pnas.2318622122.","productDescription":"e2318622122, 10 p.","ipdsId":"IP-166203","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":498685,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1073/pnas.2318622122","text":"Publisher Index Page"},{"id":498552,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"122","issue":"12","noUsgsAuthors":false,"publicationDate":"2025-03-17","publicationStatus":"PW","contributors":{"authors":[{"text":"Scarpetta, Simon G.","contributorId":364984,"corporation":false,"usgs":false,"family":"Scarpetta","given":"Simon","middleInitial":"G.","affiliations":[{"id":87022,"text":"University of San Francisco; UC Berkeley","active":true,"usgs":false}],"preferred":false,"id":953556,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fisher, Robert D. 0000-0002-2956-3240 rdfisher@usgs.gov","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":3913,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert","email":"rdfisher@usgs.gov","middleInitial":"D.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":953557,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Karin, Benjamin R.","contributorId":364985,"corporation":false,"usgs":false,"family":"Karin","given":"Benjamin","middleInitial":"R.","affiliations":[{"id":6609,"text":"UC Berkeley","active":true,"usgs":false}],"preferred":false,"id":953558,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Niukula, Jone B.","contributorId":364986,"corporation":false,"usgs":false,"family":"Niukula","given":"Jone","middleInitial":"B.","affiliations":[{"id":87025,"text":"NatureFiji-MareqetiViti","active":true,"usgs":false}],"preferred":false,"id":953559,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Corl, Ammon","contributorId":364987,"corporation":false,"usgs":false,"family":"Corl","given":"Ammon","affiliations":[{"id":6609,"text":"UC Berkeley","active":true,"usgs":false}],"preferred":false,"id":953560,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jackman, Todd R.","contributorId":364988,"corporation":false,"usgs":false,"family":"Jackman","given":"Todd","middleInitial":"R.","affiliations":[{"id":12766,"text":"Villanova University","active":true,"usgs":false}],"preferred":false,"id":953561,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"McGuire, Jimmy A.","contributorId":364989,"corporation":false,"usgs":false,"family":"McGuire","given":"Jimmy","middleInitial":"A.","affiliations":[{"id":6609,"text":"UC Berkeley","active":true,"usgs":false}],"preferred":false,"id":953562,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

It parallels an underlying northeast‐oriented Late‐Precambrian–Early‐Cambrian structural fabric, called the Wabash Valley fault zone, and is within an area of modern, historic, and paleo seismicity, called the Wabash Valley seismic zone. In addition, the MBS acts as a boundary of the Wabash River floodplain, as well as Pleistocene glacial outwash channels, which show evidence of frequent outburst flood events. To better understand the MBS’s equivocal origin in this complex geologic environment, we acquired a 917‐m‐long seismic‐reflection survey across its axis to assess the subsurface geologic configuration. The resultant image indicates a complex set of faults that antiformally fold and displace the top of Paleozoic bedrock by ∼12&nbsp;m across the survey. Moreover, fault and/or fold deformation extends into the shallowest imaged Quaternary strata at ∼6&nbsp;m below the ground surface. This suggests the MBS origin is related to underlying Quaternary reactivated, positively inverted faults rather than exclusively to glacial outburst flood erosion.

Quantitative hydrologic data for the main stems of these rivers underlie numerous scientific investigations, statistical models, and decision-making processes for local, State, and Federal agencies involved in the Upper Mississippi River Restoration program. Although historical hydrologic data exist, data representing potential future conditions of the Upper Mississippi and Illinois Rivers lack the resolution necessary to anticipate biotic and abiotic responses to altered hydrology and to determine resilient management actions. A source of future hydrologic scenarios is the readily available LOCA–VIC–mizuRoute hydrologic data products (named for the chain of models the data are produced from—localized constructed analogs, Variable Infiltration Capacity macroscale hydrological model, and the mizuRoute hydrologic routing model—that we shorten further to LVM in this report) that include simulated discharges for historic and future timeframes. The objective of this study is to assess the reliability of the hydrologic data products for their use in Upper Mississippi River Restoration program applications. Key study questions are (1) do the hydrologic data products reproduce characteristics of hydrology necessary to support ecological modeling and restoration decision-making applications within the Upper Mississippi River Restoration program? and (2) are there geographic differences in the reliability of the hydrologic data products?</p><p>Seven characteristics of river hydrology were selected related to flow magnitude, seasonality, and regime for evaluation. The seven characteristics were calculated using observed and historical simulated hydrologic data at 19 U.S. Geological Survey streamgages throughout the basins of the Upper Mississippi and Illinois Rivers; two streamgages are located on the main stem of the Mississippi River and two streamgages are located on the main stem of the Illinois River. Statistical comparisons between observed and historical simulated characteristics indicated that the hydrologic data products did not reliably represent historical hydrologic conditions in the basin or main stem. The hydrologic data products we evaluated could not reliably capture the overall hydrologic regime or flow magnitudes; the latter is evidenced by substantial underestimates of discharge at most streamgages. Seasonal hydrologic characteristics were captured more reliably than flow magnitude, but overall correspondence was low for most streamgages. A weak latitudinal pattern in seasonal characteristics indicated the hydrologic data products poorly represent streamflow timing in snow-affected regions of the basin. Discrepancies in magnitude, seasonality, and regime indicate the potential for multiple sources of error. Because poor correspondence was present across all 19 streamgages, it was not possible to identify specific drivers of poor performance (that is, drainage area or geography).

Toxic baiting is a primary method used to suppress many invasive species, including the brown treesnake (</span><i>Boiga irregularis</i><span>) in Guam. Based on limited alternative approaches to assess tool efficacy in snake removal, bait take is often used as a proxy for snake removal, despite evidence that nontarget species remove baits in a spatially heterogeneous manner. Using photographic validation, we tested take rates of mouse, chick, and rat baits by brown treesnakes and nontargets, including invertebrates, at three sites undergoing snake removal for vertebrate conservation goals. We also identified the ant species present on baits for a subset of baits. Take rates by snakes and nontargets varied by site. We found that nontarget take (22–42%) was considerably greater than take by brown treesnakes (1–13%). In addition, baits that had ants were taken less often by snakes as compared to baits without ants (7–12% vs. 8–52%, respectively). The dominant ant species collected from ant bait stations affiliated with baits was&nbsp;</span><i>Solenopsis</i><span>&nbsp;spp. Ant presence appeared to have deterred brown treesnakes from consuming baits, and ant removal or prevention may improve take rates by brown treesnakes. There was not, however, a consistent correction factor that could be applied across sites to estimate brown treesnake take rates of baits without photographic validation.</span></p>","language":"English","publisher":"BioOne","doi":"10.2984/79.3.1","usgsCitation":"Nafus, M.G., Reyes, A.A., Daria, B.S., Quinata, C., and Miller, R., 2025, A comparative evaluation of bait types taken by brown treesnakes or other nontarget species, including ants: Pacific Science, v. 79, no. 3, p. 333-344, https://doi.org/10.2984/79.3.1.","productDescription":"12 p.","startPage":"333","endPage":"344","ipdsId":"IP-166846","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":501883,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Guam","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              144.99148065516488,\n              13.611465954876934\n            ],\n            [\n              144.84690279350855,\n              13.678447233419732\n            ],\n            [\n              144.58464527701608,\n              13.446382566640793\n            ],\n            [\n              144.61322462176173,\n              13.2157295756938\n            ],\n            [\n              144.75612134549243,\n              13.184631911187978\n            ],\n            [\n              144.82336686254172,\n              13.395690523177166\n            ],\n            [\n              144.99148065516488,\n              13.611465954876934\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"79","issue":"3","noUsgsAuthors":false,"publicationDate":"2025-12-29","publicationStatus":"PW","contributors":{"authors":[{"text":"Nafus, Melia G. 0000-0002-7325-3055 mnafus@usgs.gov","orcid":"https://orcid.org/0000-0002-7325-3055","contributorId":197462,"corporation":false,"usgs":true,"family":"Nafus","given":"Melia","email":"mnafus@usgs.gov","middleInitial":"G.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":958110,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reyes, Amanda A","contributorId":368919,"corporation":false,"usgs":false,"family":"Reyes","given":"Amanda","middleInitial":"A","affiliations":[{"id":54632,"text":"Research Corporation of the University of Guam","active":true,"usgs":false}],"preferred":false,"id":958111,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Daria, Bae S.","contributorId":368920,"corporation":false,"usgs":false,"family":"Daria","given":"Bae","middleInitial":"S.","affiliations":[{"id":54632,"text":"Research Corporation of the University of Guam","active":true,"usgs":false}],"preferred":false,"id":958112,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Quinata, Christiana-Jo Concepcion 0009-0000-6209-2391","orcid":"https://orcid.org/0009-0000-6209-2391","contributorId":357886,"corporation":false,"usgs":true,"family":"Quinata","given":"Christiana-Jo Concepcion","affiliations":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":958113,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, Ross","contributorId":368921,"corporation":false,"usgs":false,"family":"Miller","given":"Ross","affiliations":[{"id":38228,"text":"University of Guam","active":true,"usgs":false}],"preferred":false,"id":958114,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Yet, parasites rarely act in isolation and may be one of a multitude of biotic and abiotic stressors that collectively shape mortality risk in vertebrate populations. We quantified sources of mortality in a low-density population of moose (</span><i>Alces alces</i><span>) in New York State and investigated factors including parasite infection, nutritional limitation, and thermal stress influencing mortality risk in calf moose. We observed high rates of annual survival (0.81–0.92) in adult (</span><i>n</i><span> = 25) and calf (</span><i>n</i><span> = 27) moose monitored 2015–2018 and 2022–2024, respectively. The majority of cause-specific mortality was attributed to disease induced by giant liver fluke (</span><i>Fascioloides magna</i><span>; 75% in adults, 67% in calves). Calf mortality risk increased by 72% for every unit increase in giant liver fluke infection risk, measured as cumulative monthly proportion of wetlands used by moose, and decreased by 16% with each additional unit of nutritional energy available. The combination of flukes, coinfecting parasites, and available nutritional energy is important to calf survival in this population, highlighting the importance of managing multiple stressors for species conservation, although the effects are hard to disentangle given the high rates of survival observed. Identifying causes of mortality and mechanisms underlying increased mortality risk contributes to the continued conservation of moose in fluctuating populations and highlights the importance of managing parasite-induced disease.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/ece3.72721","usgsCitation":"Grauer, J.A., Frair, J.L., Schuler, K.L., Lejeune, M., Kramer, D.W., and Fuller, A.K., 2025, Moose survival and habitat‐associated risk of endoparasites: Ecology and Evolution, v. 15, no. 12, e72721, 13 p., https://doi.org/10.1002/ece3.72721.","productDescription":"e72721, 13 p.","ipdsId":"IP-174117","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":498940,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.72721","text":"Publisher Index Page"},{"id":498845,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New York","otherGeospatial":"Adirondack Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -74.95550657922735,\n              44.95159248774067\n            ],\n            [\n              -74.95550657922735,\n              43.58240923383917\n            ],\n            [\n              -73.37197044848568,\n              43.58240923383917\n            ],\n            [\n              -73.37197044848568,\n              44.95159248774067\n            ],\n            [\n              -74.95550657922735,\n              44.95159248774067\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"15","issue":"12","noUsgsAuthors":false,"publicationDate":"2025-12-29","publicationStatus":"PW","contributors":{"authors":[{"text":"Grauer, Jennifer A.","contributorId":365370,"corporation":false,"usgs":false,"family":"Grauer","given":"Jennifer","middleInitial":"A.","affiliations":[{"id":48981,"text":"State University of New York","active":true,"usgs":false}],"preferred":false,"id":954228,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frair, Jacqueline L.","contributorId":365371,"corporation":false,"usgs":false,"family":"Frair","given":"Jacqueline","middleInitial":"L.","affiliations":[{"id":48981,"text":"State University of New York","active":true,"usgs":false}],"preferred":false,"id":954229,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schuler, Krysten L.","contributorId":365372,"corporation":false,"usgs":false,"family":"Schuler","given":"Krysten","middleInitial":"L.","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":954230,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lejeune, Manigandan","contributorId":359243,"corporation":false,"usgs":false,"family":"Lejeune","given":"Manigandan","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":954231,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kramer, David W.","contributorId":365373,"corporation":false,"usgs":false,"family":"Kramer","given":"David","middleInitial":"W.","affiliations":[{"id":48981,"text":"State University of New York","active":true,"usgs":false}],"preferred":false,"id":954232,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Fuller, Angela K. 0000-0002-9247-7468 afuller@usgs.gov","orcid":"https://orcid.org/0000-0002-9247-7468","contributorId":3984,"corporation":false,"usgs":true,"family":"Fuller","given":"Angela","email":"afuller@usgs.gov","middleInitial":"K.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":954233,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Management actions may offset climate-related changes to biodiversity, although identifying appropriate strategies is challenging. Our goal was to identify the impacts of climate change on freshwater biota (i.e., fish and mussel) distribution and management actions that may offset the climate change impacts across the northeastern United States. We used land use, geography, stream temperature, and streamflow variables to predict species distribution in a baseline scenario, climate change scenario, and several climate change plus land use management scenarios. We found climate change negatively impacted (i.e., reduced the probability of occurrence of) coldwater fishes and reduced the relative occurrence probability of fluvial specialist and coolwater fishes compared to other species. Increasing watershed forest cover best offset these negative impacts and minimized the predicted transition from coldwater fish dominance to warmwater fish dominance in coldwater habitats; however, no intervention fully offset the negative impacts of climate change on vulnerable fish groups (i.e., coldwater and fluvial specialist fishes). Climate change negatively impacted all vulnerable groups of mussels (e.g., lotic species, drying intolerant) and mussel species richness. Combining multiple management interventions (e.g., increase forest cover, dam removal, etc.) had the greatest potential to offset the negative impacts of climate change for freshwater mussels and fishes. This study provides managers a comparison of management interventions across a landscape to combat the impacts of climate change on biota in streams and rivers.</span></span></p>","language":"English","publisher":"PLOS","doi":"10.1371/journal.pclm.0000742","usgsCitation":"Rogers, J.B., DiRenzo, G.V., Roy, A.H., Carmignani, J., O’Brien, R.S., Quiñones, R.M., Richards, T., 2025, Watershed forest cover and habitat restoration can offset some negative impacts of climate change on freshwater fishes and mussels: PLOS Climate, v. 4, no. 12, e0000742, 29 p., https://doi.org/10.1371/journal.pclm.0000742.","productDescription":"e0000742, 29 p.","ipdsId":"IP-182150","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":500579,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pclm.0000742","text":"Publisher Index Page"},{"id":500352,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont","otherGeospatial":"northeastern United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -73.55344226729666,\n              44.99179802700698\n            ],\n            [\n              -73.59343473444298,\n              41.090513543768935\n            ],\n            [\n              -69.55059933191644,\n              41.164342871024274\n            ],\n            [\n              -69.64172720632452,\n              43.04155239993982\n            ],\n            [\n              -66.87105464402323,\n              44.75557463899469\n            ],\n            [\n              -67.950275967363,\n              47.38036747688005\n            ],\n            [\n              -69.36016438239204,\n              47.4800358530578\n            ],\n            [\n              -71.1276825828879,\n              45.47486977480742\n            ],\n            [\n              -73.55344226729666,\n              44.99179802700698\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"4","issue":"12","noUsgsAuthors":false,"publicationDate":"2025-12-26","publicationStatus":"PW","contributors":{"authors":[{"text":"Rogers, Jennifer B.","contributorId":366772,"corporation":false,"usgs":false,"family":"Rogers","given":"Jennifer","middleInitial":"B.","affiliations":[{"id":36396,"text":"University of Massachusetts","active":true,"usgs":false}],"preferred":false,"id":956213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DiRenzo, Graziella Vittoria 0000-0001-5264-4762","orcid":"https://orcid.org/0000-0001-5264-4762","contributorId":243404,"corporation":false,"usgs":true,"family":"DiRenzo","given":"Graziella","email":"","middleInitial":"Vittoria","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":956214,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Roy, Allison H. 0000-0002-8080-2729 aroy@usgs.gov","orcid":"https://orcid.org/0000-0002-8080-2729","contributorId":4240,"corporation":false,"usgs":true,"family":"Roy","given":"Allison","email":"aroy@usgs.gov","middleInitial":"H.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":956215,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Carmignani, Jason","contributorId":360465,"corporation":false,"usgs":false,"family":"Carmignani","given":"Jason","affiliations":[{"id":86008,"text":"Natural Heritage and Endangered Species Program","active":true,"usgs":false}],"preferred":false,"id":956216,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"O’Brien, Rebecca S.M.","contributorId":366774,"corporation":false,"usgs":false,"family":"O’Brien","given":"Rebecca","middleInitial":"S.M.","affiliations":[{"id":36396,"text":"University of Massachusetts","active":true,"usgs":false}],"preferred":false,"id":956217,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Quiñones, Rebecca M.","contributorId":366775,"corporation":false,"usgs":false,"family":"Quiñones","given":"Rebecca","middleInitial":"M.","affiliations":[{"id":16900,"text":"Massachusetts Division of Fisheries and Wildlife","active":true,"usgs":false}],"preferred":false,"id":956218,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Richards, Todd","contributorId":359346,"corporation":false,"usgs":false,"family":"Richards","given":"Todd","affiliations":[{"id":16900,"text":"Massachusetts Division of Fisheries and Wildlife","active":true,"usgs":false}],"preferred":false,"id":956219,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Warmer temperatures were associated with lower abundance and larger fish at low elevations and with higher abundance and smaller fish at higher elevations. Low flows were related to increased abundance and smaller fish at low elevations but to decreased abundance at high elevations, suggesting that lower elevation streams, which tend to be larger, provided additional habitat during low flows. High flows were negatively related to abundance and positively related to average size, suggesting emigration of fish in younger age-classes. Overall, steelhead exhibited greater resilience to warm temperatures at high elevations and, conversely, greater resilience to low and high flows at lower elevations. Understanding how streamflow and temperature affect juvenile steelhead abundance and size structure provides insight into how climate change can affect juvenile steelhead production.</span></span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/cjfas-2025-0057","usgsCitation":"Vosbigian, R., Ballinger, A., Link, T.E., Copeland, T., Falcy, M.R., 2025, Elevation mediates juvenile steelhead demographic response to stream temperature and flow: Canadian Journal of Fisheries and Aquatic Sciences, v. 82, 16 p., https://doi.org/10.1139/cjfas-2025-0057.","productDescription":"16 p.","ipdsId":"IP-176032","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":500829,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1139/cjfas-2025-0057","text":"Publisher Index Page"},{"id":500381,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Clearwater River basin, Salmon River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -115.88693697098967,\n              46.239806253101705\n            ],\n            [\n              -116.08725001215848,\n              44.58877340680024\n            ],\n            [\n              -113.81504145984678,\n              44.65156356442722\n            ],\n            [\n              -113.88746821077106,\n              45.50351976892712\n            ],\n            [\n              -114.52675806291347,\n              45.59810863893756\n            ],\n            [\n              -114.2253382218617,\n              46.239806253101705\n            ],\n            [\n              -115.88693697098967,\n              46.239806253101705\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"82","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Vosbigian, Ryan A.","contributorId":354342,"corporation":false,"usgs":false,"family":"Vosbigian","given":"Ryan A.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956005,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ballinger, Alexa","contributorId":366508,"corporation":false,"usgs":false,"family":"Ballinger","given":"Alexa","affiliations":[{"id":36224,"text":"Idaho Department of Fish and Game","active":true,"usgs":false}],"preferred":false,"id":956006,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Link, Timothy E.","contributorId":366509,"corporation":false,"usgs":false,"family":"Link","given":"Timothy","middleInitial":"E.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956007,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Copeland, Timothy","contributorId":354344,"corporation":false,"usgs":false,"family":"Copeland","given":"Timothy","affiliations":[{"id":36224,"text":"Idaho Department of Fish and Game","active":true,"usgs":false}],"preferred":false,"id":956008,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Falcy, Matthew Richard 0000-0002-3332-2239","orcid":"https://orcid.org/0000-0002-3332-2239","contributorId":288500,"corporation":false,"usgs":true,"family":"Falcy","given":"Matthew","email":"","middleInitial":"Richard","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":956009,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Many existing tools are primarily expert-focused, and redesigning them can be challenging because experts and non-experts interact with tools differently, existing users may be resistant to changes, and there is little guidance on how to prioritize redesign efforts and demonstrate their efficacy. In this report, we present a case study of a user-centered redesign of an established environmental decision-support tool—the U.S. Geological Survey WaterWatch. WaterWatch supports flood, drought, and other water resource management decisions through the display of water levels at gages across the United States. Using a participatory process, we identified a functional change (replacing the existing rainbow colormap), created an alternative design, and tested the alternative’s usability through two general public surveys. The results showed that replacing the rainbow colormap with a more intuitive diverging colormap improves usability, regardless of the audience’s subjective preference for the rainbow color scheme. In addition, we demonstrated the importance of using legends to improve the audience’s understanding of the map symbols. This study demonstrates how user-centered design approaches can be used to inform the design of high-profile products and tools.</p>","language":"English","publisher":"U.S. Geological

However, there is an ongoing debate regarding what geological features on Mars provide definitive evidence for such systems. Although earlier studies have modeled hydrothermal processes in Martian craters, they often lacked integration with shock physics hydrocodes to constrain initial impact conditions. The importance of this two-code coupling was demonstrated by successfully replicating alteration signatures in the Earth's Haughton impact structure. In this study, we use a similar two-code approach, combining the iSALE hydrocode with the HYDROTHERM hydrothermal model to simulate the full evolution of impact-generated hydrothermal systems. We apply this method to craters the size of Jezero (∼50&nbsp;km) and Gale (∼154&nbsp;km) in diameter. Although Jezero's interior is largely buried, our results align with hypothesized hydrothermal vents and alteration minerals near central uplifts in similarly sized exposed craters, such as Toro and Auki. Furthermore, our models correspond to alteration patterns observed by the Curiosity in the lower layers of Mount Sharp, which may represent remnants of impact-driven hydrothermal activity. A key finding is that these systems may persist much longer than previously estimated. Our simulations suggest that a Jezero-sized system could remain habitable for thermophiles for approximately 720,000&nbsp;years, whereas a Gale-sized system could persist for nearly 2&nbsp;million years. Additionally, simulations under unsaturated crustal conditions reveal that air-dominated near-surface layers can suppress vertical fluid flow, enabling deep subsurface alteration without producing detectable mineral signatures at the surface.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2024JE008896","usgsCitation":"Trowbridge, A.J., Marchi, S., Taron, J.M., and Osinski, G.R., 2025, Advancing current understanding of Martian impact-generated hydrothermal systems through novel coupled modeling: Insights from Gale, Jezero, and other craters: Journal of Geophysical Research - Planets, v. 130, no. 12, e2024JE008896, 28 p., https://doi.org/10.1029/2024JE008896.","productDescription":"e2024JE008896, 28 p.","ipdsId":"IP-174851","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":500613,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2024je008896","text":"Publisher Index Page"},{"id":500553,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Mars","volume":"130","issue":"12","noUsgsAuthors":false,"publicationDate":"2025-12-23","publicationStatus":"PW","contributors":{"authors":[{"text":"Trowbridge, Alexander J.","contributorId":367033,"corporation":false,"usgs":false,"family":"Trowbridge","given":"Alexander","middleInitial":"J.","affiliations":[{"id":87529,"text":"NASA Astrobiology Postdoctoral Program","active":true,"usgs":false}],"preferred":false,"id":956618,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Marchi, Simone","contributorId":367034,"corporation":false,"usgs":false,"family":"Marchi","given":"Simone","affiliations":[{"id":37298,"text":"Southwest Research Institute, Boulder, CO","active":true,"usgs":false}],"preferred":false,"id":956619,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Taron, Joshua M. 0000-0003-2719-3917","orcid":"https://orcid.org/0000-0003-2719-3917","contributorId":248769,"corporation":false,"usgs":true,"family":"Taron","given":"Joshua","email":"","middleInitial":"M.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":956620,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Osinski, Gordon R.","contributorId":367035,"corporation":false,"usgs":false,"family":"Osinski","given":"Gordon","middleInitial":"R.","affiliations":[{"id":87530,"text":"Dept.

Evidence-based insights for environmental protection","docAbstract":"A substantial body of evidence exists demonstrating that exposure to environmental contaminants can alter animal behavior. Moreover, methodological and technological advancements, as well as increasing standardization, mean that behavioral ecotoxicity studies are more rigorous and reliable than ever before. Despite this, behavioral data are still seldom used in the risk assessment and regulation of chemicals. This is partly due to a lack of clarity among some stakeholders about whether changes in behavior at the individual level result in population-level outcomes. To address this, we first consider the state of evidence within the field of behavioral ecotoxicology linking individual-level behavioral alterations with population-level consequences. We then assess the evidence from behavioral ecology and other neighboring fields that supports this link. Further, we evaluate whether some behavioral endpoints are more easily tied to population-level changes than others. In this regard, we propose combining insights from two complementary ecological frameworks─the functional trait framework and the limiting traits framework─to evaluate which behaviors should be prioritized in ecotoxicological research and regulatory efforts. We contend that the link between behavioral changes and population-level outcomes is evident, with behavioral endpoints representing a highly valuable yet so far underutilized line of evidence in applied environmental protection.","language":"English","publisher":"American Chemical Society","doi":"10.1021/acs.est.5c07777","usgsCitation":"Bertram, M.G., Ågerstrand, M., Brand, J.A., Brooks, B.W., Dang, Z., Ford, A.T., Hollert, H., LeFauve, M.K., Manera, J.L., Martin, J.M., Michelangeli, M., Moiron, M., Moore, E.R., Puglis, H.J., Sih, A., Steevens, J.A., Thoré, E.S., Wong, B.B., Zink, L., and Bodin, T., 2025, Are behavioural ecotoxicity endpoints relevant at the population level?

Potash is recognized as a critical mineral in Canada as it is the largest source of potassium used in fertilizers. It is essential for global agricultural productivity and food security. Canada is the world’s largest potash exporter with vast deposits in the widely mined Prairie Evaporite of Saskatchewan, which formed in the epicontinental Elk Point Basin during the Middle Devonian. Potash is also found in the Windsor Group of Atlantic Canada where it formed in a series of tectonically active basins during the Mississippian that have undergone substantial post-depositional subsurface alteration and deformation. Potash deposits were mined in New Brunswick up until 2016. Both deposits are salt giants, recording times in the geologic record of extensive and long-lasting evaporite genesis under arid conditions in restricted seas. This paper reviews the geological and economic significance of Canadian potash, including (1) the genesis of each deposit, (2) diagenetic, erosional, and tectonic modification, and (3) exploration and mining in each basin. Underdeveloped regions, possible undiscovered resources, environmental considerations, and the importance of sustainable practices in light of climate change and socioeconomic risks are also addressed.</span></span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/facets-2024-0363","usgsCitation":"E.J.

These springs are located north of Bright Angel Wash, an ephemeral channel that receives treated effluent from the South Rim Wastewater Treatment Plant (SRWTP). Although water flows southwest and away from the canyon, there is evidence that treated wastewater is finding a flow path along fractures associated with the Bright Angel Fault back to water sources along the South Rim.</p><p>The CECs identified during the April 2021 sampling included several per- and polyfluoroalkyl substances (PFAS) and pharmaceutical compounds. The PFAS compounds detected only consisted of perfluoroalkyl acids, and these were only detected at Bright Angel Wash (treated wastewater), Monument Spring, and upper Horn Bedrock Spring. The other five sampled springs (the Salt Creek, Horn East Alluvium, Garden, Pumphouse, and Pipe Springs) had no detections of PFAS compounds. The five perfluoroalkyl acids detected at Monument Spring (in descending order of concentration) were perfluorobutanesulfonic acid (PFBS), perfluoropentanoic acid, perfluorooctanoic acid, perfluorohexanoic acid, and perfluorooctanesulfonic acid. Only the short-chained PFBS and perfluorobutanoic acid compounds were detected at the upper Horn Bedrock Spring. All the same perfluoroalkyl acids were found at Bright Angel Wash, except for PFBS.</p><p>Monument Spring was the only spring to have detections of pharmaceuticals. The two pharmaceuticals detected at the highest concentrations at Monument Spring were diphenhydramine (antihistamine) and carbamazepine (anticonvulsant or anti-epileptic drug). The other detected pharmaceuticals included (in descending order of concentration) fluconazole (antifungal), sulfamethoxazole (antibiotic), metformin (diabetes drug), tramadol (opioid analgesic), and venlafaxine (antidepressant and nerve pain medication). The same pharmaceuticals were detected in the wastewater at Bright Angel Wash but in greater concentrations. No CEC concentrations measured at Monument Spring exceeded any drinking water standards or human health benchmarks; however, most of the compounds detected have no regulatory standards. Studies of the ecological effects of these compounds show that some of the compounds detected can have endocrine and physiological effects, but generally, effects were observed at concentrations multiple orders of magnitude greater than what was measured during the April 2021 study.</p><p>Data from 1980 through 2022 retrieved from the Water Quality Portal were combined with data from the one-time synoptic sampling in April 2021 to assess the usefulness of other analytes for identifying a wastewater connection to South Rim springs. Most of the historical water chemistry data showed a statistical difference between samples collected within and east of the Garden Creek watershed and samples collected from locations in watersheds to the west of Garden Creek, including the Horn Creek, Salt Creek, Monument Creek, and Hermit Creek watersheds, which roughly align with the Bright Angel Fault. Most of the historical analytes were inconclusive as potential wastewater tracers, but nitrate, chloride, and gadolinium data possibly support the historical contribution of wastewater to Monument Spring.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20255095","collaboration":"Prepared in cooperation with the National Park Service, Grand Canyon National Park","usgsCitation":"Paretti, N.V., Beisner, K.R., and Shepherd, S.J.R., 2025, Assessment of treated wastewater infiltration in Bright Angel Wash and the potential for contaminants of emerging concern influencing spring water quality along the South Rim of the Grand Canyon in Grand Canyon National Park, Arizona (ver. 1.1, 2026): U.S. Geological Survey Scientific Investigations Report 2025–5095, 59 p., https://doi.org/10.3133/sir20255095.","productDescription":"ix, 59 p.","numberOfPages":"59","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-159478","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":499495,"rank":7,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_119152.htm","linkFileType":{"id":5,"text":"html"}},{"id":499484,"rank":6,"type":{"id":25,"text":"Version History"},"url":"https://pubs.usgs.gov/sir/2025/5095/versionHist.txt","linkFileType":{"id":2,"text":"txt"},"description":"SIR 2025-5095 Version History"},{"id":497774,"rank":4,"type":{"id":31,"text":"Publication XML"},"url":"https://pubs.usgs.gov/sir/2025/5095/sir20255095.XML","linkFileType":{"id":8,"text":"xml"},"description":"SIR 2025-5095 XML"},{"id":497773,"rank":3,"type":{"id":39,"text":"HTML Document"},"url":"https://pubs.usgs.gov/publication/sir20255095/full","linkFileType":{"id":5,"text":"html"},"description":"SIR 2025-5095 HTML"},{"id":497772,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/sir/2025/5095/sir20255095.pdf","size":"11.6 MB","linkFileType":{"id":1,"text":"pdf"},"description":"SIR 2025-5095 PDF"},{"id":497775,"rank":5,"type":{"id":34,"text":"Image Folder"},"url":"https://pubs.usgs.gov/sir/2025/5095/images/"},{"id":497771,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/sir/2025/5095/coverthb2.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Bright Angel Wash, Grand Canyon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -112.25,\n              36.1\n            ],\n            [\n              -112.25,\n              35.94693133579284\n            ],\n            [\n              -112,\n              35.94693133579284\n            ],\n            [\n              -112,\n              36.1\n            ],\n            [\n              -112.25,\n              36.1\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","edition":"Version 1.0: December 29, 2025; Version 1.1: February 3, 2026","contact":"<p>Director, <a href=\"https://www.usgs.gov/centers/arizona-water-science-center\" data-mce-href=\"https://www.usgs.gov/centers/arizona-water-science-center\">Arizona Water Science Center</a><br>U.S. Geological Survey<br>520 N.

Considered sources included three upland land-use (cropland, forest, and roads), two in-channel (streambank and streambed sediment), and one that connects uplands to the stream channel (gullies). Source apportionment used established methods in the SedSAT tool. Source scenarios included land-use + streambank (4src), 4src + gully, 4src + streambed, and 4src + gully + streambed (6src).</p><h3 class=\"c-article__sub-heading\" data-test=\"abstract-sub-heading\">Results</h3><p>There were no statistically significant differences in median grain size, organic carbon, or sediment-bound P as a function of collection method. In-channel sources were the largest proportional SS source, regardless of season, hydrologic condition, collection method, or source scenario. Source verification highlighted which source fingerprints were most accurately defined and implications for SS target apportionment.</p><h3 class=\"c-article__sub-heading\"

As an important part of many Earth systems, seasonal snow is also an essential source of water for many human populations and ecosystems around the world. As such, the measurement of seasonal snow and characterization of uncertainty in those measurements is crucial. To elucidate potential uncertainty attributable to commonly used field spectrometers (and to a lesser extent imaging spectrometers) and associated reference panels, this work presents results from an intercalibration experiment conducted synchronously with the NASA 2023 Snow Experiment (SnowEx) Albedo campaign near Fairbanks, Alaska USA. Three sets of experiments were carried out under controlled laboratory conditions to characterize the radiometric and spectral wavelength consistency of the instruments as well as the white reference panels used to calculate reflectance from field measurements. Although there was generally good agreement between the instruments, panels, and the references, there were also some notable differences. One instrument showed an average&nbsp;−&nbsp;74&nbsp;% change from the reference for radiance, and multiple instruments exceeded the suggested 0.5&nbsp;nm threshold for spectral wavelength scale. The Discussion section highlights how some of these findings and their implications could improve future field campaigns and general use/maintenance of these high-precision scientific instruments.</span></span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.coldregions.2025.104800","usgsCitation":"Roberts-Pierel, B.M., Crawford, C., Brown, S.W., Kokaly, R.F.,
