Quantitative mineral resource assessment of lithium pegmatite deposits in the southern Appalachian orogen Quantitative mineral resource assessment of lithium pegmatite deposits in the southern Appalachian orogen
The first quantitative mineral resource assessment for undiscovered lithium pegmatite deposits in the southern Appalachian region of the United States was conducted. Permissive tracts for lithium pegmatite deposits were delineated by integrating lithological, tectonic, geochemical, geophysical and mineral occurrence data. Lithium pegmatite prospectivity of the tracts was ranked with...

Rain interacts with directional wind to cause nest failures within breeding colonies of Western and Clark's Grebes Rain interacts with directional wind to cause nest failures within breeding colonies of Western and Clark's Grebes
Western Grebe (Aechmophorus occidentalis) and Clark's Grebe (Aechmophorus clarkii) populations have declined across their range, and they are species of high conservation concern. Cascade Reservoir in central Idaho supports one of the largest breeding colonies of Aechmophorus grebes in North America (and the largest in Idaho), but few offspring are produced from the colony in most years...

Range-wide relative abundance of Pyrgus centaureae wyandot (W.H. Edwards, 1863) (Appalachian Grizzled Skipper) Range-wide relative abundance of Pyrgus centaureae wyandot (W.H. Edwards, 1863) (Appalachian Grizzled Skipper)
The US Fish and Wildlife Service has designated the butterfly Pyrgus centaureae wyandot (Appalachian Grizzled Skipper [AGS]) to be at-risk, based on its declining populations and the lack of information on its status. Our objective was to conduct range-wide surveys to locate extant AGS colonies and to quantify the number of AGS observed at each location. From 2021 to 2024, we conducted...

The U.S. Fish and Wildlife Service has designated the Pyrgus centaureae wyandot (Appalachian Grizzled Skipper [AGS]) to be at-risk, based on its declining populations and the lack of information on its status. The objective of this study was to complete range-wide surveys to locate extant AGS colonies and to quantify the number of AGS observed at each location. From 2021–24, 284 surveys...

Rapid characterization of the 2025 Mw 8.8 Kamchatka, Russia earthquake Rapid characterization of the 2025 Mw 8.8 Kamchatka, Russia earthquake
The 29 July 2025 Mw 8.8 Kamchatka, Russia, earthquake was the sixth largest instrumentally recorded earthquake. This event was seismically well observed at regional and teleseismic distances, but publicly available near‐source data were sparse at the time of the event, presenting unique challenges for rapid source and impact characterization. The U.S. Geological Survey (USGS) National...

Rapid earthquake magnitude classification via P-wave strains from borehole strainmeters and Distributed Acoustic Sensing Rapid earthquake magnitude classification via P-wave strains from borehole strainmeters and Distributed Acoustic Sensing
Distributed Acoustic Sensing (DAS) offers a promising approach for earthquake early warning (EEW) in settings where seismic networks are costly to maintain. By repurposing fiber-optic cables as dense strainmeter arrays, DAS enables real-time earthquake detection wherever those fibers are accessible. However, poor azimuthal coverage and challenges in estimating magnitude from strain...

Rapid expansion of genotype D1.1 A(H5N1) influenza viruses in wild birds across North America during the 2024 migratory season Rapid expansion of genotype D1.1 A(H5N1) influenza viruses in wild birds across North America during the 2024 migratory season
In late 2021, high pathogenicity avian influenza A(H5N1) clade 2.3.4.4b viruses entered North America and reassorted rapidly with local avian influenza viruses. In September 2024, we detected a new reassortant later classified as genotype D1.1. Using active and passive avian influenza surveillance across Canada and the USA, we tracked the emergence and rapid spread of D1.1 viruses in...

Rapid hydrothermal triggering of induced seismicity at the Coso Geothermal Field Rapid hydrothermal triggering of induced seismicity at the Coso Geothermal Field
The long-term producing Coso Geothermal Field (CGF) in California operates over 100 wells tapping into a reservoir characterized by an extensive fracture network, complex fluid pathways, and regular seismic activity. Understanding the interaction between seismicity and injection can shed important light on the hydrothermal characteristics of the field. Here, we analyze 15 years of local...

Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska) Rapid seismic and infrasound assessment of large landslides: A case study from Denali National Park and Preserve (Alaska)
Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide-generated seismic and infrasound (low-frequency atmospheric sound) waves can be remotely detected in near real-time. This information can significantly...

Rare earth element potential in coal and coal ash in the U.S. Gulf Coast Rare earth element potential in coal and coal ash in the U.S. Gulf Coast
United States heavy reliance on imports of critical minerals (CMs), including rare earth elements (REEs), underscores the importance of development of domestic sources. The study objective was to quantify CM and REE concentrations in coal and coal ash in the US Gulf Coast region. CM and REE concentrations were measured for 118 samples from outcrops and 14 mines in the Gulf Coast. Results...

Rearing method has limited effect on post-release movement of reintroduced age-0 Lake Sturgeon Rearing method has limited effect on post-release movement of reintroduced age-0 Lake Sturgeon
Overfishing, habitat loss, and pollution caused the extirpation of Lake Sturgeon (Acipenser fulvescens) throughout much of the Great Lakes. A Lake Sturgeon reintroduction program using two rearing strategies began in 2018 in the Maumee River, a tributary of Lake Erie. We assessed the movement of streamside or traditionally reared age-0 Lake Sturgeon using acoustic telemetry to determine...
