In this study, we explore how invasive reptiles influence seed dispersal dynamics in the Greater Everglades ecosystem using two case studies: the Burmese python (</span><i>Python bivittatus</i><span>) and the Argentine black and white tegu (</span><i>Salvator merianae</i><span>). Guided by a conceptual framework, we investigate three primary mechanisms through which invasive species may alter seed outcomes: direct seed consumption, predation on seed dispersers before seed ingestion, and secondary seed dispersal via predation on animals that have already consumed seeds. Burmese pythons, as apex predators, may contribute to seed dispersal through diploendozoochory while simultaneously driving trophic cascades that restructure the seed disperser community. Tegus, as omnivorous frugivores, directly consume and disperse a wide diversity of plant seeds. We documented 25 seed morphotypes in python diets and 73 in tegu diets, spanning a broad 38 families and including native, endangered, and invasive plant species. Using a binary interaction network, we found that these reptiles exhibit high generalization, nestedness, and connectance—suggesting they are becoming functionally integrated into Everglades seed dispersal networks. These findings reveal that invasive reptiles not only disrupt native plant–animal interactions but may also reshape them, with implications for ecosystem stability, restoration, and management.</span></p>","language":"English","publisher":"Zoological Society of London","doi":"10.1111/jzo.70082","usgsCitation":"Figueroa, A., Davis, K.R., Harman, M.E., Bartoszek, I.A., Easterling, I.C., Yackel Adams, A.A., and Romagosa, C.M., 2026, Double agents: Invasive Burmese pythons (Python bivittatus) and Argentine black and white tegus (Salvator merianae) as potential seed dispersers in south Florida: Journal of Zoology, v. 328, no. 2, p. 187-202, https://doi.org/10.1111/jzo.70082.","productDescription":"16 p.","startPage":"187","endPage":"202","ipdsId":"IP-175854","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":503244,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Greater Everglades","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.86487171131805,\n              26.86767945037043\n            ],\n            [\n              -79.82200627856571,\n              26.86767945037043\n            ],\n            [\n              -79.82200627856571,\n              25.005644614374646\n            ],\n            [\n              -81.86487171131805,\n              25.005644614374646\n            ],\n            [\n              -81.86487171131805,\n              26.86767945037043\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"328","issue":"2","noUsgsAuthors":false,"publicationDate":"2025-11-09","publicationStatus":"PW","contributors":{"authors":[{"text":"Figueroa, Adrian","contributorId":370151,"corporation":false,"usgs":false,"family":"Figueroa","given":"Adrian","affiliations":[{"id":87973,"text":"UF and USFWS","active":true,"usgs":false}],"preferred":false,"id":959871,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Davis, Katherine R.","contributorId":370152,"corporation":false,"usgs":false,"family":"Davis","given":"Katherine","middleInitial":"R.","affiliations":[{"id":57420,"text":"uf","active":true,"usgs":false}],"preferred":false,"id":959872,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Harman, Madison E.A. 0000-0003-1560-6024","orcid":"https://orcid.org/0000-0003-1560-6024","contributorId":364936,"corporation":false,"usgs":false,"family":"Harman","given":"Madison","middleInitial":"E.A.","affiliations":[{"id":78927,"text":"Cherokee Nation Systems Solutions","active":true,"usgs":false}],"preferred":false,"id":959873,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bartoszek, Ian A.","contributorId":370153,"corporation":false,"usgs":false,"family":"Bartoszek","given":"Ian","middleInitial":"A.","affiliations":[{"id":12563,"text":"Conservancy of Southwest Florida","active":true,"usgs":false}],"preferred":false,"id":959874,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Easterling, Ian C.","contributorId":370154,"corporation":false,"usgs":false,"family":"Easterling","given":"Ian","middleInitial":"C.","affiliations":[{"id":12563,"text":"Conservancy of Southwest Florida","active":true,"usgs":false}],"preferred":false,"id":959875,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Yackel Adams, Amy A. 0000-0002-7044-8447 yackela@usgs.gov","orcid":"https://orcid.org/0000-0002-7044-8447","contributorId":3116,"corporation":false,"usgs":true,"family":"Yackel Adams","given":"Amy","email":"yackela@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":959876,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Romagosa, Christina M.","contributorId":370155,"corporation":false,"usgs":false,"family":"Romagosa","given":"Christina","middleInitial":"M.","affiliations":[{"id":57420,"text":"uf","active":true,"usgs":false}],"preferred":false,"id":959877,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Despite an ever‐growing library of ground‐breaking studies, questions remain about the potential of fiber‐optic sensing technologies as tools for advancing if not revolutionizing earthquake‐hazards‐related research, monitoring, and early warning systems. A working group convened to explore these topics; we comprehensively examined the application of fiber optics in various aspects of earthquake hazards, encompassing earthquake source processes, crustal imaging, data archiving, and technological challenges. There is great potential for fiber‐optic systems to advance earthquake monitoring and understanding, but to fully unlock their capabilities requires continued progress in key areas of research and development, including instrument testing and validation, increased dynamic range for applications focused on larger earthquakes, and continued improvement in subsurface and source imaging methods. A key current stumbling block results from the lack of clear data archiving requirements, and we propose an initial strategy that balances data volume requirements with preserving key data for a broad range of future studies. In addition, we demonstrate the potential for fiber‐optic sensing to impact monitoring efforts by documenting the data completeness in a number of long‐term experiments. Finally, we outline the features of a instrument testing facility that would enable progress toward reliable and standardized distributed acoustic sensing data. Overcoming these current obstacles would facilitate progress in fiber‐optic sensing and unlock its potential application to a broad range of earthquake hazard problems.</span></p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0220250067","usgsCitation":"McGuire, J.J., Barbour, A.J., Spica, Z.J., Rodríguez Tribaldos, V.,

Harrat Khaybar, western Saudi Arabia, is one of the youngest and potentially most active volcanic fields on the Arabian plate, has been active since ca. 1.7 Ma, and is characterized by a spectrum of rock compositions ranging from predominantly alkalic basalt to trachyte and comendite. Previous work in Harrat Khaybar utilizing&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar incremental heating geochronology to constrain morphological preservation and superpositional relationships bracketed the volcanic activity into broad age groups in intervals of ∼150 k.y., and the youngest and most compositionally evolved volcanoes, including Jabal Abyad, Jabal Bayda, and Jabal Qidr, were assigned to the age groups between ca. 300 ka and present. Herein, we establish a detailed chronology of prehistoric silicic and historical basaltic eruptions at central Harrat Khaybar using four independent eruption age determination techniques: zircon double-dating (ZDD), which combines&nbsp;</span><sup>238</sup><span>U-</span><sup>230</sup><span>Th disequilibrium or U-Pb with (U-Th)/He dating; zircon U-Pb dating; cosmogenic&nbsp;</span><sup>3</sup><span>He dating; and cosmogenic&nbsp;</span><sup>36</sup><span>Cl geochronology. These were employed to accurately date six volcanic centers, including the comenditic Jabal Abyad, Jabal Bayda, Jabal Ibayl, and Jabal Alhayyirah, the trachytic Jabal Aluthmor, and the basaltic Jabal Qidr. Additionally, our previously published&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar ages have been recalculated using isochron intercept (nonatmospheric)&nbsp;</span><sup>40</sup><span>Ar/</span><sup>36</sup><span>Ar for the trapped Ar component. Our new results reveal that zircon rims from Jabal Abyad and Jabal Bayda define isochron&nbsp;</span><sup>238</sup><span>U-</span><sup>230</sup><span>Th crystallization ages of 125 ± 4 ka and 144 ± 6 ka, concordant with ZDD eruption ages of 132 ± 4 ka and 149 ± 5 ka, respectively. Zircon U-Pb crystallization and (U-Th)/He eruption ages from Jabal Alhayyirah are concordant at 471 ± 14 ka and 458 ± 18 ka, respectively. Finally, zircons from the nearby Jabal Ibayl yield a U-Pb weighted mean crystallization age of 566 ± 16 ka concordant with the corresponding (U-Th)/He eruption age of 554 ± 12 ka, both of which are notably older than the previously proposed eruption ages of 300−150 ka. Recalculations of published&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar ages for the youngest volcanoes at central Harrat Khaybar are now in excellent agreement with new geochronological data.</span></p><p><span>Our new age data reveal several new insights into the development of Harrat Khaybar. It is now clear that the comenditic eruptions do not belong to the same eruptive phase and indicate an extended history during which comendites have episodically punctuated the basaltic volcanism since at least 600 ka. The data indicate that Jabal Ibayl and Jabal Alhayyirah represent separate older volcanic events, whereas the younger Jabal Abyad and Jabal Bayda volcanoes appear to be coeval, and their spatial proximity implies that they share a magmatic lineage and maybe a common plumbing system. Zircon age spectra of the comendites reveal obvious xenocrysts and antecrysts indicating assimilation of basement and plutonic progenitors, but otherwise they define broad unimodal populations of crystallization ages that overlap within error with the respective eruption ages. We interpret this to indicate that zircon crystallization continued up to the time of eruption. The cosmogenic ages of Jabal Aluthmor and Jabal Qidr reveal that these centers erupted as recently as ca. 2000 and 760 years ago, respectively. Broadly coeval young silicic and basaltic eruptions at northern Harrat Rahat, the harrat immediately south of Harrat Khaybar, may imply a shared geodynamic forcing between the two adjacent volcanic fields.</span></p>","language":"English","publisher":"GeoScienceWorld","doi":"10.1130/B38611.1","usgsCitation":"Aohali, A., de Silva, S.L., de Leon, A., Lewis, C., Schmitt, A.K., Danišík, M., Stelten,

North America has 2 major data sources for estimating population trends of breeding birds—the North American Breeding Bird Survey (BBS) and the global participatory science project eBird. Because the surveys differ in protocols, coverage, and data analysis, their trend estimates are expected to vary in magnitude, direction, and/or precision for at least some species and regions. Here, we compare independently derived estimates of population change between 2012 and 2022 for every combination of species and bird conservation region (BCR) covered by both surveys (</span><i>n</i><span> = 5,577 combinations) as well as aggregated across entire ranges or within the U.S. or Canada. Uncertainty was substantial for both surveys, though more prevalent for BBS (81% of credibility intervals for estimates included zero) than eBird (34% of confidence intervals overlapped zero). We found agreement of trend directions between the 2 surveys. Only 1.3% of estimated trends were significant in opposite directions between the 2 surveys for all species/BCR combinations, with the median difference in trend magnitude being –0.02% (BBS minus eBird trend). Correlations between the 2 were strongest for estimates that were graded as being high credibility compared to estimates judged to have medium or low credibility. Both surveys were subject to species, taxonomic, and regional effects that influenced agreement. Overall, we show where trend estimates derived from BBS and eBird agree, explore where they diverge, present several comparisons to assist in interpreting results from both surveys, and inform efforts to integrate information from each.</span></span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/ornithapp/duaf077","usgsCitation":"Robinson, O.J., Johnston, A.J., Hochachka, W.M., Hostetler, J.A., Sauer, J.R., Auer, T., Strimas-Mackey, M.E., Ligocki, S., Faraco-Hadlock, N.A., Ruiz-Gutierrez, V., Rodewald, A.D., and Fink, D., 2026, Same view through a different lens: Comparing population trends for North American birds using eBird and the Breeding Bird Survey: Ornithological Applications, v. 128, no. 1, p. 1-14, https://doi.org/10.1093/ornithapp/duaf077.","productDescription":"14 p.","startPage":"1","endPage":"14","ipdsId":"IP-177306","costCenters":[{"id":50464,"text":"Eastern Ecological Science Center","active":true,"usgs":true}],"links":[{"id":498606,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -175.5769656031165,\n              67.88007213476573\n            ],\n            [\n              -176.42265817434867,\n              52.09754159577638\n            ],\n            [\n              -135.3326753777096,\n              55.172434116597884\n            ],\n            [\n              -120.43638889508058,\n              32.147432273276934\n            ],\n            [\n              -76.5966100414586,\n              24.358972522659556\n            ],\n            [\n              -50.64255884378724,\n              46.04534849315602\n            ],\n            [\n              -60.903583596490165,\n              62.58237847273696\n            ],\n            [\n              -117.88795050621641,\n              71.73176576156126\n            ],\n            [\n              -152.156676231909,\n              72.85004301491678\n            ],\n            [\n              -175.5769656031165,\n              67.88007213476573\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"128","issue":"1","noUsgsAuthors":false,"publicationDate":"2025-11-05","publicationStatus":"PW","contributors":{"authors":[{"text":"Robinson, Orin J.","contributorId":220077,"corporation":false,"usgs":false,"family":"Robinson","given":"Orin","middleInitial":"J.","affiliations":[{"id":13360,"text":"Auburn University","active":true,"usgs":false}],"preferred":false,"id":953770,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, Alison J.","contributorId":365147,"corporation":false,"usgs":false,"family":"Johnston","given":"Alison","middleInitial":"J.","affiliations":[{"id":87068,"text":"University of St Andrews, St Andrews, UK","active":true,"usgs":false}],"preferred":false,"id":953771,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hochachka, Wesley M.","contributorId":365148,"corporation":false,"usgs":false,"family":"Hochachka","given":"Wesley","middleInitial":"M.","affiliations":[{"id":36682,"text":"Cornell Lab of Ornithology","active":true,"usgs":false}],"preferred":false,"id":953772,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hostetler, J.

New U-series ages of corals, amino acid data from mollusks, and detailed analyses of fossil mollusk assemblages are presented that reconcile many of the apparently discordant results from previous studies. The two lowest-elevation terraces are Q1 (lower) and Q2 (upper); both are thought to date from high-sea stands of marine isotope stage (MIS) 5, the last interglacial complex. A combination of U-series dating and amino acid racemization results indicates that the Q1 terrace probably dates to the ∼80&nbsp;ka high-sea stand of MIS 5a. U-series analyses of corals from the Q2 terrace show open-system histories, but consideration of two alternative open-system histories indicates that this terrace likely hosts corals dating to the high-sea stands of MIS 5c (∼105–95&nbsp;ka) and MIS 5e (∼130–115&nbsp;ka). Amino acid ratios in the fossil bivalve<span>&nbsp;</span><i>Leukoma staminea</i><span>&nbsp;</span>(Conrad, 1837) support the age differences between the two terraces and the open-system models suggested by the U-series data. Alkenone studies along much of the coast of California have shown that sea surface temperatures (SSTs) of the eastern Pacific Ocean were warmer than present during MIS 5e. During MIS 5c, on the other hand, SSTs were either similar to the present or cooler, but in either case, much cooler than during MIS 5e. The paleozoogeographic aspects of the molluscan faunas from the Q2 terrace support an interpretation that these deposits contain a mixture of fossils from both the MIS 5c and 5e high-sea stands. Fossils from the Q2 terrace include southern or southward-ranging species (likely dating to MIS 5e) and northern or northward-ranging species (likely dating to MIS 5c). A mixture of MIS 5e and MIS 5c fossils on the Q2 terrace is consistent with similar data reported for other localities in California. This phenomenon is explained by glacial isostatic adjustment (GIA) processes, which brought about a higher-than-present sea level during MIS 5c. GIA processes, combined with a low uplift rate, allowed mixing of MIS 5e fossils during the MIS 5c high-sea stand through capture of an MIS 5e terrace that had experienced minimal uplift in ∼20,000 years. Terrace reoccupation and fossil mixing such as that in the San Luis Obispo Bay area can be expected along any part of the Pacific Coast of North America that was affected by GIA processes and where uplift rates are low.</div></div></div></div></div><div id=\"preview-section-introduction\"></div>","language":"English","publisher":"Elsevier","doi":"10.1016/j.palaeo.2025.113354","usgsCitation":"Muhs, D., Groves, L.T., Schumann, R.R., and Bright, J., 2026, Reconciliation of geochronology and paleozoogeography for Quaternary marine terraces, San Luis Obispo Bay area, California, USA: Palaeogeography, Palaeoclimatology, Palaeoecology, v. 681, 113354, 29 p., https://doi.org/10.1016/j.palaeo.2025.113354.","productDescription":"113354, 29 p.","ipdsId":"IP-179136","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":499374,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Luis Obispo Bay area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121,\n              35.5\n            ],\n            [\n              -121,\n              35\n            ],\n            [\n              -120.5,\n              35\n            ],\n            [\n              -120.5,\n              35.5\n            ],\n            [\n              -121,\n              35.5\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"681","noUsgsAuthors":false,"publicationDate":"2025-11-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Muhs, Daniel R. 0000-0001-7449-251X dmuhs@usgs.gov","orcid":"https://orcid.org/0000-0001-7449-251X","contributorId":168575,"corporation":false,"usgs":true,"family":"Muhs","given":"Daniel R.","email":"dmuhs@usgs.gov","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":954857,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Groves, Lindsey T. 0000-0002-2097-2689","orcid":"https://orcid.org/0000-0002-2097-2689","contributorId":365815,"corporation":false,"usgs":false,"family":"Groves","given":"Lindsey","middleInitial":"T.","affiliations":[{"id":12725,"text":"Natural History Museum of Los Angeles County","active":true,"usgs":false}],"preferred":false,"id":954858,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schumann, R.

This study investigates the multi-year dynamics of root strength following wildfire in coniferous forests of western Oregon and evaluates implications for postfire slope stability. Root tensile strength was measured through laboratory testing of 969 roots collected from 26 test pits over four postfire timeframes: unburned conditions, 4–12&nbsp;months postfire (Cedar Creek, 2022), 24–35&nbsp;months postfire (Holiday Farm, 2020), and 59–67&nbsp;months postfire (Eagle Creek, 2017). Variables analyzed include root diameter, tensile thread strength, stiffness, progressive tensile strength with displacement, time-dependent strength and ductility, root area ratio, and cohesion. Results indicate a 50% reduction in root strength after wildfire, with the lowest values occurring around 4 years postfire. Projections indicate it could take 10–22&nbsp;years following fire for root strength to recover to 70% and 90% of the prefire original root strength, respectively. This timeline indicates a multi-year window of vulnerability for shallow landslides that reaches a maximum approximately 4 years following fire. Brittle failure behavior was observed in burned root systems compared to unburned root systems, signaling a more abrupt loss of strength at yield. Simple slope stability analyses show that reduced root strength can lead to instability on more gentle slopes and under less saturation in comparison to unburned conditions. These findings highlight the critical role of root reinforcement in postfire slope stability and the long-term implications of wildfire disturbance on landslide susceptibility.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10346-025-02643-3","usgsCitation":"Sousa, D.F., Fulmer, E., Sanders, M.A., Mathews, N.W., Roering, J.J., Rengers, F.K., Mirus, B., Burns, W., Olsen, M.J., and Leshchinksy, B., 2026, The influence of postfire root strength decay on shallow landslide susceptibility in western Oregon: Landslides, v. 23, p. 1-18, https://doi.org/10.1007/s10346-025-02643-3.","productDescription":"18 p.","startPage":"1","endPage":"18","ipdsId":"IP-173335","costCenters":[{"id":78941,"text":"Geologic Hazards Science Center - Landslides / Earthquake Geology","active":true,"usgs":true}],"links":[{"id":504992,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","otherGeospatial":"western Oregon","volume":"23","noUsgsAuthors":false,"publicationDate":"2025-11-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Sousa, David F.M.","contributorId":371792,"corporation":false,"usgs":false,"family":"Sousa","given":"David","middleInitial":"F.M.","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":962361,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fulmer, Erik","contributorId":371817,"corporation":false,"usgs":false,"family":"Fulmer","given":"Erik","affiliations":[],"preferred":false,"id":962389,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sanders, Maryn A. 0000-0001-8172-8359","orcid":"https://orcid.org/0000-0001-8172-8359","contributorId":371793,"corporation":false,"usgs":false,"family":"Sanders","given":"Maryn","middleInitial":"A.","affiliations":[{"id":6604,"text":"University of Oregon","active":true,"usgs":false}],"preferred":false,"id":962362,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mathews, Nicolas W. 0000-0002-4647-4039","orcid":"https://orcid.org/0000-0002-4647-4039","contributorId":371794,"corporation":false,"usgs":false,"family":"Mathews","given":"Nicolas","middleInitial":"W.","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":962363,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Roering, Josh J. 0000-0003-0647-3338","orcid":"https://orcid.org/0000-0003-0647-3338","contributorId":371795,"corporation":false,"usgs":false,"family":"Roering","given":"Josh","middleInitial":"J.","affiliations":[{"id":6604,"text":"University of Oregon","active":true,"usgs":false}],"preferred":false,"id":962364,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rengers, Francis K. 0000-0002-1825-0943 frengers@usgs.gov","orcid":"https://orcid.org/0000-0002-1825-0943","contributorId":150422,"corporation":false,"usgs":true,"family":"Rengers","given":"Francis","email":"frengers@usgs.gov","middleInitial":"K.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":962365,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mirus, Benjamin B. 0000-0001-5550-014X","orcid":"https://orcid.org/0000-0001-5550-014X","contributorId":267912,"corporation":false,"usgs":true,"family":"Mirus","given":"Benjamin B.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":962366,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Burns, William 0000-0002-4379-6198","orcid":"https://orcid.org/0000-0002-4379-6198","contributorId":344522,"corporation":false,"usgs":false,"family":"Burns","given":"William","affiliations":[{"id":32397,"text":"Oregon Department of Geology and Mineral Industries","active":true,"usgs":false}],"preferred":false,"id":962367,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Olsen, Michael J. 0000-0002-2989-5309","orcid":"https://orcid.org/0000-0002-2989-5309","contributorId":343799,"corporation":false,"usgs":false,"family":"Olsen","given":"Michael","email":"","middleInitial":"J.","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":962368,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Leshchinksy, Ben 0000-0003-3890-1368","orcid":"https://orcid.org/0000-0003-3890-1368","contributorId":297919,"corporation":false,"usgs":false,"family":"Leshchinksy","given":"Ben","email":"","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":962369,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

The MFFZ has the potential to generate magnitude 7 earthquakes, and it hosted a magnitude 6 earthquake in 1995. It has also produced exotic events, such as very‐low‐frequency earthquakes and nucleation signals. We use network‐matched filtering and relative earthquake relocation techniques to derive a detailed catalog of earthquake locations for the MFFZ. The catalog spans from August 2014 to December 2019, a time period including 13 temporary seismic stations in the region. Our results provide the most complete catalog for the MFFZ and include deeper events, clusters of shallow seismicity, and a complex and segmented fault structure not observed in the original regional catalog. We document right‐lateral strike‐slip faulting, conjugate to the main northeast‐striking left‐lateral faults of the MFFZ. Below Nenana basin, the relocated seismicity reveals northwest‐dipping left‐lateral faults, supporting the inference that deep crustal active faulting is associated with recent basin deformation.</span></p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120250177","usgsCitation":"Sims, N.E., Tape, C., Ruppert, N., and West, M.E., 2026, High-precision earthquake catalog for Minto Flats fault zone, central Alaska, reveals complex and conjugate faulting: Bulletin of Seismological Society of America, v. 116, no. 1, p. 375-396, https://doi.org/10.1785/0120250177.","productDescription":"22 p.","startPage":"375","endPage":"396","ipdsId":"IP-182902","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":499435,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Minto Flats fault zone","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -146.5,\n              65.2\n            ],\n            [\n              -150,\n              65.2\n            ],\n            [\n              -150,\n              64.2\n            ],\n            [\n              -146.5,\n              64.2\n            ],\n            [\n              -146.5,\n              65.2\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"116","issue":"1","noUsgsAuthors":false,"publicationDate":"2025-11-04","publicationStatus":"PW","contributors":{"authors":[{"text":"Sims, Nealey E.","contributorId":365831,"corporation":false,"usgs":false,"family":"Sims","given":"Nealey","middleInitial":"E.","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":954904,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tape, Carl","contributorId":219960,"corporation":false,"usgs":false,"family":"Tape","given":"Carl","email":"","affiliations":[{"id":40098,"text":"Geophysical Institute, 2156 Koyukuk Drive, University of Alaska Fairbanks, Fairbanks, AK 99775","active":true,"usgs":false}],"preferred":false,"id":954905,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ruppert, Natalia A. 0000-0003-0589-1159","orcid":"https://orcid.org/0000-0003-0589-1159","contributorId":351514,"corporation":false,"usgs":true,"family":"Ruppert","given":"Natalia A.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":954906,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"West, Michael E.","contributorId":365832,"corporation":false,"usgs":false,"family":"West","given":"Michael","middleInitial":"E.","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":954907,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Multi-population models are useful tools for integrating diverse datasets, reducing biases, and deriving survival estimates across differing spatial scales. We conducted a range-wide, multi-population apparent annual survival analysis for a declining songbird,&nbsp;</span><i>Vermivora chrysoptera</i><span>&nbsp;(Golden-winged Warbler), using data from 18 sites across its breeding and nonbreeding grounds. This Nearctic-Neotropical migrant breeds in 2 disjunct regional populations, the Great Lakes and Appalachian Mountains, which are experiencing different rates of decline. We aimed to quantify regional-, site-, and sex-specific apparent annual survival estimates to identify geographic patterns or demographic factors influencing population declines. We used simulations to assess the precision of our estimates. Our models did not reveal a substantial difference in apparent annual survival between the Great Lakes (0.41, 95% credible interval (CrI):0.31–0.50) and the Appalachian regions (0.49, 95% CrI: 0.36–0.60), as CrIs overlapped. Site-specific estimates also showed no clear differences in apparent annual survival among sites representing both regional populations. Male apparent annual survival tended to be greater than female apparent annual survival in both regions, though CrI’s overlapped. Our study suggests demographic factors other than adult annual survival likely play a larger role in recent regional and range-wide population declines, such as productivity, juvenile/immature survival, or recruitment. Simulations indicate that improving recapture probability and study duration of datasets could lead to more precise apparent annual survival estimates. However, our model produced CrI ranges comparable to the most ideal data collection scenario, suggesting the lack of trends we found was not due to variability in our estimates. We stress the importance of addressing inherent biases in survival datasets and the need for standardized collaborative efforts to inform species conservation on a range-wide scale.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/ornithology/ukaf049","usgsCitation":"Filiberti, E.N., Roth, A.M., Thogmartin, W.E., Royal, E.J., Aldinger, K.R.,

Some of the WCARS frontier basins are currently being investigated to increase our understanding of these basins in light of new commercial discoveries. The present study was performed in the Babouri-Figuil Basin (BFB), which is genetically related to the WCARS and constitutes an area of interest in terms of petroleum prospecting, where the distribution of petroleum source rocks and potential targets for petroleum exploration across the entire basin is poorly understood. For the current study, an integrated facies analysis along with organic and inorganic geochemical techniques were applied to the basin's Cretaceous deposits with the aim of reconstructing the paleodepositional environment, assessing factors that triggered the input of organic matter, and providing a spatial overview of the organic matter accumulation in the basin based on outcrop samples. An alluvial fan-lacustrine-braided river system is inferred from the facies analysis of the stratigraphic sequence consisting of conglomerate, sandstone, siltstone, limestone, marlstone, and claystone. Bulk analysis of organic matter reveals that black shale and massive claystone are the main prospective petroleum source rocks in the basin. Inorganic geochemical analyses reveal the influence of anoxic conditions, moderate to high primary productivity, and low terrigenous inputs in organic matter enrichment. The formations rich in organic matter are predominantly concentrated in the western and eastern parts of the basin which may represent areas with depressions, characterized by high accommodation space. In terms of the regional context of the WCARS rift basins, typical hydrocarbon exploration in the BFB may target basal-conglomerate, sandstone beds situated directly above or/and interbedded with the Lower Cretaceous source rocks, and the Upper Cretaceous sandstone beds. Basement rocks (granite, granodiorite, and gneisses) and oil shale deposits may represent potential unconventional hydrocarbon exploration. The current integrated study provides an insight that should guide future hydrocarbon exploration campaigns in the basin.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jafrearsci.2025.105894","usgsCitation":"Manga, W.G., Hackley, P.C., Bessong, M., Hatcherian, J.J., Ashukem, E.K., Guedala, A., Meying, A., and Samankassou, E., 2026, Sedimentological and geochemical characterization of lacustrine deposits of the Babouri-Figuil basin, northern Cameroon: Implications for source rocks distribution and petroleum exploration: Journal of African Earth Sciences, v. 233, 105894, 16 p., https://doi.org/10.1016/j.jafrearsci.2025.105894.","productDescription":"105894, 16 p.","ipdsId":"IP-171940","costCenters":[{"id":49175,"text":"Geology, Energy & Minerals Science Center","active":true,"usgs":true}],"links":[{"id":502413,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://archive-ouverte.unige.ch/unige:188567","text":"External Repository"},{"id":496494,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Cameroon","otherGeospatial":"Babouri-Figuil basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              13.667,\n              9.85\n            ],\n            [\n              13.667,\n              9.6333\n            ],\n            [\n              14.0333,\n              9.6333\n            ],\n            [\n              14.0333,\n              9.85\n            ],\n            [\n              13.667,\n              9.85\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"233","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Manga, William Gaspard O.","contributorId":352997,"corporation":false,"usgs":false,"family":"Manga","given":"William","middleInitial":"Gaspard O.","affiliations":[{"id":84323,"text":"Institute of Geological and Mining Research, P.O.

Energetic acquisition and growth are key traits that affect demography and life-history strategies. Many animals that live in seasonal environments in which food availability fluctuates store energy endogenously as fat in anticipation of food shortage. Fat-storing mammalian hibernators are an extreme example of this strategy where the optimal resolution of resource allocation trade-offs is essential to survival. Hence, these species provide an opportunity to test potential causes and consequences of seasonal body mass dynamics. </p><p>2. We used a 12-year dataset with 8753 body mass records from 3351 individually marked northern Idaho ground squirrels (<i>Urocitellus brunneus</i>) – a federally threatened hibernator – to meet three objectives: (1) document seasonal body mass changes by sex, age, and reproductive status, (2) test ecological hypotheses to explain spatiotemporal variation in body mass, and (3) document fitness consequences of pre-hibernation body condition via condition-dependent overwinter survival. </p><p>3. Squirrels varied substantially in seasonal body mass dynamics. The magnitude (36-155%) and onset (late May to early July) of rapid active-season mass gain varied among demographic groups. Reproductive females acquired the necessary fat stores to survive hibernation later in the active season than did males and non-reproductive females. Moreover, squirrels with better pre-hibernation body condition were more likely to survive to the subsequent year, potentially because they allocated excess energetic reserves to prolonging hibernation via early immergence and thereby reduced predation risk. These results suggest a direct trade-off between current and future reproduction mediated by resource acquisition and allocation, as predicted by life-history theory. </p><p>4. Colder active-season temperatures and lower conspecific densities negatively influenced squirrel body condition, possibly via reductions in foraging activity associated with those conditions. These ecological effects on body condition constrain resource allocation and demographic outcomes. As such, our results can help guide research and conservation strategies to benefit hibernating animals.</p>","language":"English","publisher":"British Ecological Society","doi":"10.1111/1365-2656.70160","usgsCitation":"Allison, A.Z., Conway, C.J., Goldberg, A.R., Morris, A.E., and Hakanson, E.C., 2026, Seasonal body mass dynamics mediate life-history trade-offs in a hibernating mammal: Journal of Animal Ecology, v. 95, no. 3, p. 383-396, https://doi.org/10.1111/1365-2656.70160.","productDescription":"14 p.","startPage":"383","endPage":"396","ipdsId":"IP-178391","costCenters":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"links":[{"id":500344,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":500576,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/1365-2656.70160","text":"Publisher Index Page"}],"country":"United States","state":"Idaho","otherGeospatial":"northern Idaho","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -117.01727912063691,\n              48.949849031406984\n            ],\n            [\n              -117.06550577544263,\n              45.77432685387063\n            ],\n            [\n              -115.45669769129175,\n              45.603498147742044\n            ],\n            [\n              -114.14771203572005,\n              46.038667434519695\n            ],\n            [\n              -114.10553430532104,\n              46.61453544078449\n            ],\n            [\n              -115.60028001696853,\n              47.5696411418145\n            ],\n            [\n              -115.99924647829263,\n              47.875315792205775\n            ],\n            [\n              -116.04207182244672,\n              49.00063541966966\n            ],\n            [\n              -117.01727912063691,\n              48.949849031406984\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"95","issue":"3","noUsgsAuthors":false,"publicationDate":"2025-10-18","publicationStatus":"PW","contributors":{"authors":[{"text":"Allison, Austin Z.T.","contributorId":366617,"corporation":false,"usgs":false,"family":"Allison","given":"Austin","middleInitial":"Z.T.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956098,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conway, Courtney J. 0000-0003-0492-2953 cconway@usgs.gov","orcid":"https://orcid.org/0000-0003-0492-2953","contributorId":2951,"corporation":false,"usgs":true,"family":"Conway","given":"Courtney","email":"cconway@usgs.gov","middleInitial":"J.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":956099,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldberg, Amanda R.","contributorId":366618,"corporation":false,"usgs":false,"family":"Goldberg","given":"Amanda","middleInitial":"R.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956100,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Morris, Alice E.","contributorId":366619,"corporation":false,"usgs":false,"family":"Morris","given":"Alice","middleInitial":"E.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956101,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hakanson, Emma C.","contributorId":366620,"corporation":false,"usgs":false,"family":"Hakanson","given":"Emma","middleInitial":"C.","affiliations":[{"id":36394,"text":"University of Idaho","active":true,"usgs":false}],"preferred":false,"id":956102,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Listed as critically endangered in the 1960s due to poaching, vicuña numbers had been gradually recovering; however, new concerns about population stability have arisen with recent observations of sarcoptic mange outbreaks in this species. Sarcoptic mange is an infectious skin disease caused by the microscopic burrowing mite,&nbsp;</span><i>Sarcoptes scabiei</i><span>, which infects nearly 150 mammalian species globally, including guanaco and vicuña. Wild camelid populations across Argentina, Bolivia, Chile, and Peru have been affected by sarcoptic mange, with the most severe outbreaks resulting in localized extirpation. Population declines have conservation and economic implications, as many local communities harvest vicuña and guanaco fiber for profit. We review the current literature on sarcoptic mange in wild camelids from Argentina, Bolivia, Chile, and Peru to establish a current state of knowledge on spatial prevalence, management, and therapeutics, and identify existing knowledge gaps. Critical next steps include 1) implementation of effective management strategies that limit the transmission of sarcoptic mange, 2) standardization of data collected during community capture (i.e., chaccu) events, 3) assessing the potential role of community captures in mite transmission, and 4) evaluation of treatment options and best practices for implementation. Further, there is a need for capacity building to improve disease diagnostics and surveillance in wild camelids. A multisectoral collaboration between governmental authorities, communities, academic institutions, and national and international organizations focusing on wild South American camelid conservation could contribute to building actions aimed at preventing future outbreaks and mitigating the current burden of sarcoptic mange disease.</span></span></p>","language":"English","publisher":"The Wildlife Society","doi":"10.1002/jwmg.70125","usgsCitation":"Martin, A., Isasi-Catalá, E., Salgado-Caxito, M., Gallegos, A., Hostos-Olivera, L., Colchao-Claux, P., Smith, S.J., Beltran-Saavedra, F., Dougnac, C., Germana, C., Montoya, M., Carver, S., Cross, P., and Walzer, C., 2026, Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids: Journal of Wildlife Management, v. 90, no. 1, e70125, 28 p., https://doi.org/10.1002/jwmg.70125.","productDescription":"e70125, 28 p.","ipdsId":"IP-148575","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":496919,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/jwmg.70125","text":"Publisher Index Page"},{"id":496777,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"South America","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -79.89276068519384,\n              12.078777453989517\n            ],\n            [\n              -84.05130991626078,\n              -4.35532823276467\n            ],\n            [\n              -71.8782875515644,\n              -22.597367895324183\n            ],\n            [\n              -79.89276068519384,\n              -59.227926354657086\n            ],\n            [\n              -62.27262009516423,\n              -57.69795166992744\n            ],\n            [\n              -51.715750788124296,\n              -41.004192610953936\n            ],\n            [\n              -43.76235407564337,\n              -30.052154681431\n            ],\n            [\n              -32.550914183343686,\n              -4.694942975251131\n            ],\n            [\n              -59.46447023130274,\n              13.442139926888743\n            ],\n            [\n              -79.89276068519384,\n              12.078777453989517\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"90","issue":"1","noUsgsAuthors":false,"publicationDate":"2025-10-17","publicationStatus":"PW","contributors":{"authors":[{"text":"Martin, Alynn","contributorId":267906,"corporation":false,"usgs":false,"family":"Martin","given":"Alynn","affiliations":[{"id":12716,"text":"University of Tennessee","active":true,"usgs":false}],"preferred":false,"id":950772,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Isasi-Catalá, Emiliana","contributorId":362887,"corporation":false,"usgs":false,"family":"Isasi-Catalá","given":"Emiliana","affiliations":[{"id":13272,"text":"Wildlife Conservation Society","active":true,"usgs":false}],"preferred":false,"id":950773,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Salgado-Caxito, Marilia","contributorId":362888,"corporation":false,"usgs":false,"family":"Salgado-Caxito","given":"Marilia","affiliations":[{"id":37959,"text":"Pontificia Universidad Católica de Chile","active":true,"usgs":false}],"preferred":false,"id":950774,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gallegos, Ana","contributorId":362889,"corporation":false,"usgs":false,"family":"Gallegos","given":"Ana","affiliations":[{"id":13272,"text":"Wildlife Conservation Society","active":true,"usgs":false}],"preferred":false,"id":950775,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hostos-Olivera, Leonardo","contributorId":362891,"corporation":false,"usgs":false,"family":"Hostos-Olivera","given":"Leonardo","affiliations":[{"id":86553,"text":"University of Veterinary Medicine Vienna","active":true,"usgs":false}],"preferred":false,"id":950776,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Colchao-Claux, Paulo","contributorId":362894,"corporation":false,"usgs":false,"family":"Colchao-Claux","given":"Paulo","affiliations":[{"id":13272,"text":"Wildlife Conservation Society","active":true,"usgs":false}],"preferred":false,"id":950777,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Smith, Steven J.","contributorId":361158,"corporation":false,"usgs":false,"family":"Smith","given":"Steven","middleInitial":"J.","affiliations":[{"id":86223,"text":"Joint Global Change Research Institute, Pacific Northwest National Lab, College Park, MD, USA;

Establishing robust age-models and obtaining the most appropriate proxies for analysis is a complex scientific endeavor, requiring extensive resources and collaboration among specialists, including radiochronologists. Radiometric dating methods, such as&nbsp;</span><sup>210</sup><span>Pb and radiocarbon (</span><sup>14</sup><span>C), are frequently employed to establish chronologies in aquatic sedimentary deposits and peat bogs. In this study, we review key aspects of sampling, analysis, and the principles underlying&nbsp;</span><sup>210</sup><span>Pb and&nbsp;</span><sup>14</sup><span>C age-models, focusing on methods for developing robust joint chronologies for paleoenvironmental research. Drawing largely from the authors' experiences and group discussions during and after a scientific workshop in 2022, we discuss important considerations for site selection, sampling strategies, and radiometric dating to construct integrated&nbsp;</span><sup>210</sup><span>Pb and&nbsp;</span><sup>14</sup><span>C age-models. Using expert consensus, this group – called Paleostats – aims to provide a set of best practices for other geochronologists with this methods paper. Among our conclusions, we emphasize the importance of accounting for site-specific factors such as prior information on sedimentation rates to establish appropriate sampling and analytical strategies. The use of appropriate coring devices can minimize disturbance to sediments and ensure the core surface remains intact and preserved until sectioning. Where excess&nbsp;</span><sup>210</sup><span>Pb is expected, sectioning at intervals of ≤1 cm provides an adequate sampling resolution for&nbsp;</span><sup>210</sup><span>Pb dating. Exceptions are possible, allowing for ~2–3 cm sections in areas with confirmed high sedimentation rates (e.g., &gt; 1 cm yr</span><sup>−1</sup><span>). Recovering deeper core sections for&nbsp;</span><sup>14</sup><span>C dating with sufficient overlap allows for accounting errors in depth estimates made in the field. Special attention is advised during time intervals where validation proxies, such as the human-made radionuclides&nbsp;</span><sup>137</sup><span>Cs or post-bomb&nbsp;</span><sup>14</sup><span>C, are expected, and to determine the depth of secular equilibrium between&nbsp;</span><sup>210</sup><span>Pb and&nbsp;</span><sup>226</sup><span>Ra. Radiocarbon analyses are commonly performed by accelerator mass spectrometry, and age models are constructed mainly using Bayesian statistics with Markov Chain Monte Carlo techniques (e.g.,&nbsp;</span><i>Bacon</i><span>). A Bayesian approach (</span><i>Plum</i><span>) is now available for producing&nbsp;</span><sup>210</sup><span>Pb age-models, which infers the&nbsp;</span><sup>210</sup><span>Pb</span><sub>ex</sub><span>&nbsp;flux, eliminates the need for selecting an equilibrium depth, and allows dating cores with incomplete&nbsp;</span><sup>210</sup><span>Pb</span><sub>ex</sub><span>&nbsp;inventory.&nbsp;</span><i>Plum</i><span>&nbsp;offers improved chronologies by integrating raw&nbsp;</span><sup>210</sup><span>Pb and&nbsp;</span><sup>14</sup><span>C data, and these age-models can be enriched with other dating methodologies, such as identifying tephras and other well-recorded historical events. Harmonized reporting would contribute to making radiometric age-models reproducible, which would benefit from an international effort. Using&nbsp;</span><sup>210</sup><span>Pb and&nbsp;</span><sup>14</sup><span>C to produce integrated age-models may yield better insights into the interplay between natural and recent anthropogenic forcings on ecosystems. This can enhance our understanding of environmental processes and their impacts on climate change, ultimately supporting science-based assessments and decisions.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.earscirev.2025.105301","usgsCitation":"Sanchez-Cabeza, J., Aquino-López, M.A., Blaauw, M., Ruiz-Fernández, A.C.,

Here, we describe newly developed methods and software, called CatSep, that classifies subduction zone events into three primary tectonic regimes: crustal, interface, and intraslab. This method incorporates information about the location of the earthquake relative to the subducting slab, the depth of the Mohorovičić discontinuity, and the earthquake’s moment tensor. Applying this method is a first step in the NSHM workflow for regions covering U.S. subduction zones. Results using this subduction zone earthquake catalog separation tool for the 2025 Puerto Rico and U.S. Virgin Islands NSHM earthquake catalog are presented and analyzed.</p></div>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0220250078","usgsCitation":"Haynie, K.L., Thompson, E.M., Hearne, M., Hayes, G., Shelly, D.R.,

Since those initial observations, use of this seasonally available food resource by grizzly bears has grown substantially. As of 2023, we have documented 4,754 observations of grizzly bears feeding or digging at high-elevation talus slopes. We used those records to identify 36 unique moth sites in the GYE, assessed geographic characteristics of these sites, and documented chronology and frequency of use by grizzly bears. We used occurrences of radio-collared grizzly bears to identify a sample of bears that foraged at moth sites and investigated characteristics of fidelity, duration, diel activity, and movement patterns. Grizzly bears exhibited high fidelity to specific moth sites within and across years. Bears showed approximately 50% reductions in movement metrics while using sites, albeit with increased activity patterns. Estimates of feeding metrics by females exceeded those of males in intensity and duration of both use and daily activity. Given increasing human impacts and interest in observing this feeding interaction, quantifying metrics that describe the spatial and temporal patterns of moth site use by grizzly bears could be beneficial for future management. Further analyses are needed to fully examine the relationship between caloric influences of moth use on grizzly bear demographic rates.</span></p>","language":"English","publisher":"The Wildlife Society","doi":"10.1002/jwmg.70128","usgsCitation":"Clapp, J., Haroldson, M., Dellinger, J.A., Bjornlie, D., Thomposon, D.J., and van Manen, F.T., 2026, Exploring the exploitation of migratory moths by radio-marked grizzly bears in Wyoming: Journal of Wildlife Management, v. 90, no. 1, e70128, 12 p., https://doi.org/10.1002/jwmg.70128.","productDescription":"e70128, 12 p.","ipdsId":"IP-173987","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":496682,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho, Montana, Wyoming","otherGeospatial":"Greater Yellowstone Ecosystem","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -111.60498337614324,\n              45.449960321615094\n            ],\n            [\n              -111.60498337614324,\n              43.279980925896126\n            ],\n            [\n              -107.56773081455422,\n              43.279980925896126\n            ],\n            [\n              -107.56773081455422,\n              45.449960321615094\n            ],\n            [\n              -111.60498337614324,\n              45.449960321615094\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"90","issue":"1","noUsgsAuthors":false,"publicationDate":"2025-10-14","publicationStatus":"PW","contributors":{"authors":[{"text":"Clapp, Justin","contributorId":256932,"corporation":false,"usgs":false,"family":"Clapp","given":"Justin","email":"","affiliations":[{"id":36596,"text":"Wyoming Game and Fish Department","active":true,"usgs":false}],"preferred":false,"id":950722,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haroldson, Mark 0000-0002-7457-7676","orcid":"https://orcid.org/0000-0002-7457-7676","contributorId":316737,"corporation":false,"usgs":true,"family":"Haroldson","given":"Mark","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":950723,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dellinger, Justin A.","contributorId":362686,"corporation":false,"usgs":false,"family":"Dellinger","given":"Justin","middleInitial":"A.","affiliations":[{"id":36596,"text":"Wyoming Game and Fish Department","active":true,"usgs":false}],"preferred":false,"id":950724,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bjornlie, Daniel D.","contributorId":145512,"corporation":false,"usgs":false,"family":"Bjornlie","given":"Daniel D.","affiliations":[{"id":16140,"text":"Wyoming Game & Fish Department, Large Carnivore Section, Lander, Wyoming 82520, USA","active":true,"usgs":false}],"preferred":false,"id":950725,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thomposon, Daniel J.","contributorId":362689,"corporation":false,"usgs":false,"family":"Thomposon","given":"Daniel","middleInitial":"J.","affiliations":[{"id":36596,"text":"Wyoming Game and Fish Department","active":true,"usgs":false}],"preferred":false,"id":950726,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"van Manen, Frank T. 0000-0001-5340-8489 fvanmanen@usgs.gov","orcid":"https://orcid.org/0000-0001-5340-8489","contributorId":2267,"corporation":false,"usgs":true,"family":"van Manen","given":"Frank","email":"fvanmanen@usgs.gov","middleInitial":"T.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":950727,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

However, from 1998 to 2004, wetland area increased, and between 2009 and 2019, the extent of emergent wetlands did not significantly decrease. This raises the question: how did secretive marsh birds, which are tied to emergent wetlands, respond to this period of relative stability in wetland area? Here, we use&nbsp;</span><i>Rallus elegans</i><span>&nbsp;(King Rail) occurrence data collected in 2005, 2006, 2012, and 2017 in the Arkansas Delta in the United States to test the hypothesis that a period of stability in wetland vegetation is linked to stable&nbsp;</span><i>Rallus elegans</i><span>&nbsp;occupancy. Specifically, we sought to (1) quantify relationships between&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy and land cover, (2) quantify temporal trends in&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy, and (3) characterize changes in land cover types linked to&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy. We developed spatial multi-season occupancy models, and our top model contained the categorical year effect but showed no trend in&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy between 2005 and 2017, instead showing high interannual variation in occupancy. We found strong associations between&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy and emergent wetlands (positive) and elevation (negative). From 2005 to 2017 in the ∼3.7 million ha Arkansas Delta, rice crop cover decreased by 294,750 ha, emergent wetlands increased by 6,719 ha, and all other cover types increased or decreased by &lt; 7,500 ha. Thus, although emergent wetlands did increase, the total area of emergent wetlands in 2016 (22,262 ha) comprised &lt;1% of the Arkansas Delta. Our results support the hypothesis that&nbsp;</span><i>R. elegans</i><span>&nbsp;occupancy stabilized during a time when the main habitat type&nbsp;</span><i>R. elegans</i><span>&nbsp;depend on, emergent wetlands, also stabilized in spatial extent. There is an opportunity to turn the tide in&nbsp;</span><i>R. elegans</i><span>&nbsp;declines by conserving extant emergent wetlands and creating new emergent

Despite their importance, subsurface fault structures tend to be poorly constrained because of limitations in observational data. Improvements to the seismic networks and earthquake detection algorithms have increased the precision and volume of earthquake catalogs, which help illuminate detailed subsurface fault structure and provide the most direct information available about fault geometries at depth. We present a Python package to automate generating 3D fault geometries directly from hypocentral seismicity patterns. This method begins with clustering events based on their spatial density, identifying coherent patterns. Nearby clusters are then merged based on the similarity of their orientations. We fit nonplanar surfaces using support vector regression to balance surface accuracy with minimal deviations from planarity. The fault models are output as quadrilateral meshes at user‐defined resolution. In the process of generating the 3D fault surfaces, we compute the spatial density of seismicity around the surface and the planarity as quantitative metrics of the model outputs.</span></p><p><span>As a proof of concept, we apply this approach to the San Andreas–Calaveras fault junction region and the 2019 Ridgecrest earthquake sequence, both in California, which contain complex subparallel faults well defined at the Earth’s surface and abundant microseismicity. These case studies demonstrate the method’s ability to model complex fault structures, including long continuous fault surfaces, crossing faults, variably dipping segments, and subparallel faults. We test the method on both standard network catalogs and double‐difference relocated catalogs. We find that our seismicity‐based fault model results align with published 3D models that incorporate additional constraints and interpretations (<a class=\"link link-ref xref-bibr\" data-modal-source-id=\"rf51\">Plesch&nbsp;<i>et&nbsp;al.</i>, 2020</a>;&nbsp;<a class=\"link link-ref xref-bibr\" data-modal-source-id=\"rf1\">Aagaard and Hirakawa, 2021</a>).

While salinity tolerance literature is focused on controlled experiments, observed field salinity ranges of species are more disparate. The salinity ranges in which organisms are observed in the field may not align exactly with their experimentally (wet lab) determined physiological salinity tolerances, since other critical factors control species occurrence. We performed a systematic review to synthesize observed practical salinity ranges for 10 oyster and 12 seagrass species in coastal waters of the United States. Of initially returned search results for oysters and seagrass, only 11.4% and 6.5% met our review inclusion criteria, respectively, corresponding to 3 oyster species and 5 seagrass species. The majority (95%) of the 57 reviewed studies were along the Atlantic and Gulf coasts, with 68% focusing on&nbsp;</span><i>Crassostrea virginica</i><span>. Shorter studies following episodic events were more common than long-term monitoring.

However, anhydrite readily decomposes in the near-surface environment, making it difficult to recognize its former presence in rocks collected at or near Earth’s surface. In such samples, only small anhydrite inclusions fully shielded within other minerals can have survived. During a recent field trip to the southwestern USA, we sampled 17 Laramide-age (ca. 40−80 Ma) magma systems, most of which are associated with porphyry copper deposits. A systematic search for anhydrite inclusions preserved within apatite, amphibole, plagioclase, and quartz phenocrysts in ∼100 rock samples by optical microscopy and Raman spectroscopy revealed that each of these 17 magma systems was at least temporarily anhydrite-saturated. Also, most previously identified magmatic anhydrite-bearing intrusions are associated with porphyry copper deposits, and both intrusive and volcanic rocks containing magmatic anhydrite show high Sr/Y ratios. These observations suggest that anhydrite saturation and porphyry copper formation are linked via magma fractionation at high pressure. Compared to average arc magmas, anhydrite-bearing magmas are unusually oxidized and sulfur-rich and seem to also be unusually water-rich. Hence, our preferred interpretation is that magma generation and/or fractionation at high pressure promotes the formation of superhydrous and oxidized magmas, which in turn promotes high sulfur contents and ultimately the precipitation of anhydrite. The high mineralization potential of these magmas does not need to result from their high sulfur content but could be caused by other properties of high-pressure magmas.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/G53661.1","usgsCitation":"Audétat, A., Chang, J., and Gaynor, S.P., 2026, Widespread anhydrite saturation in Laramide-age arc magmas of southwestern USA: Geology, v. 54, no. 1, p. 19-23, https://doi.org/10.1130/G53661.1.","productDescription":"5 p.","startPage":"19","endPage":"23","ipdsId":"IP-180127","costCenters":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":496491,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona, New Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -114.1850161548798,\n              37.09668430702368\n            ],\n            [\n              -114.17123099542934,\n              36.1314881664468\n            ],\n            [\n              -114.53871291780632,\n              36.149655948885254\n            ],\n            [\n              -114.81618548536994,\n              35.86279700093031\n            ],\n            [\n              -114.72255144506553,\n              32.378354757715044\n            ],\n            [\n              -111.30008643678198,\n              31.339553209100846\n            ],\n            [\n              -109.30561954381162,\n              31.352787834987573\n            ],\n            [\n              -108.17268046973098,\n              31.288413412134357\n            ],\n            [\n              -108.08261646812497,\n              31.7457427678113\n            ],\n            [\n              -103.05693498349231,\n              31.994084642806044\n            ],\n            [\n              -103.05693498349231,\n              37.09668430702368\n            ],\n            [\n              -114.1850161548798,\n              37.09668430702368\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"54","issue":"1","noUsgsAuthors":false,"publicationDate":"2025-10-03","publicationStatus":"PW","contributors":{"authors":[{"text":"Audétat, Andreas","contributorId":348171,"corporation":false,"usgs":false,"family":"Audétat","given":"Andreas","affiliations":[{"id":83309,"text":"Bavarian Geoinstitute, University of Bayreuth","active":true,"usgs":false}],"preferred":false,"id":949942,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chang, Jia","contributorId":348172,"corporation":false,"usgs":false,"family":"Chang","given":"Jia","affiliations":[{"id":83309,"text":"Bavarian Geoinstitute, University of Bayreuth","active":true,"usgs":false}],"preferred":false,"id":949943,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gaynor, Sean Patrick 0000-0002-8353-511X","orcid":"https://orcid.org/0000-0002-8353-511X","contributorId":346264,"corporation":false,"usgs":true,"family":"Gaynor","given":"Sean","email":"","middleInitial":"Patrick","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":949944,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
