Earthquake magnitude and source parameter estimation with a distributed acoustic sensing dataset in the Gorda subduction zone Earthquake magnitude and source parameter estimation with a distributed acoustic sensing dataset in the Gorda subduction zone
Distributed acoustic sensing (DAS) systems offer a cost‐effective way to create large‐scale strainmeter arrays for seismological applications using fiber‐optic cables. DAS‐based strain measurements are known to be influenced by various factors, bringing into question their general reliability for accurate earthquake characterization. A 15‐km‐long DAS deployment in northern California was

Spatiotemporal overlap of mallards with poultry farms is associated with greater risk of avian influenza wild bird spillover events Spatiotemporal overlap of mallards with poultry farms is associated with greater risk of avian influenza wild bird spillover events
Animal movement influences local transmission and geographic spread of pathogens. Waterfowl are known reservoirs of pathogens, including H5 goose/Guangdong lineage (H5 GsGd) highly pathogenic avian influenza (HPAI). This HPAI virus lineage causes high rates of morbidity and mortality in domestic poultry and many wild bird species. Mallards (Anas platyrhynchos) are a generalist waterfowl...

Update to a management-focused population viability analysis for North Atlantic right whales Update to a management-focused population viability analysis for North Atlantic right whales
We provide an update to the recently published population viability analysis for North Atlantic right whales (Eubalaena glacialis). The update includes improvements to the reproduction modeling and also shares additional context given evidence of reduced mortality indicated by recent population monitoring. Projections from the analysis are used to quantify simulated population sizes...

Combining scanning electron microscopy, X-ray diffraction, and X-ray fluorescence to characterize shear zones at the Pogo gold deposit, Alaska Combining scanning electron microscopy, X-ray diffraction, and X-ray fluorescence to characterize shear zones at the Pogo gold deposit, Alaska
This study employs a multi-method analytical approach to characterize the mineralogical, geochemical, and textural properties of fault rocks from the Pogo gold mine in the Yukon-Tanana Upland, central Alaska. Specifically, we examine cataclasites, to document the structural and geochemical evolution of shear zones and their associations with gold mineralization. To investigate the shear...

One hundred ninety-nine dead birds: Review of the scientific basis of ecological incident reporting requirements for pesticide registrants under Fifra § 6(A)(2) One hundred ninety-nine dead birds: Review of the scientific basis of ecological incident reporting requirements for pesticide registrants under Fifra § 6(A)(2)
The U.S. Environmental Protection Agency (EPA) regulates pesticide use in the United States. The EPA is charged by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) with ensuring that a pesticide will not cause unreasonable adverse effects on the environment. Incident reports (documentation of exposure and injury from pesticide applications) can serve as a reality check on...

Tertiary metallogeny of the Rocky Mountains Province, USA Tertiary metallogeny of the Rocky Mountains Province, USA
Tertiary ore deposits in the Rocky Mountains physiographic province primarily formed through magmatic-hydrothermal processes associated with shifting tectonics and lithospheric conditions. Important deposit types in the province are calc-alkaline and Climaxtype porphyry; high-, medium-, and low-sulfidation epithermal; alkalic magmatic; carbonate replacement; tungsten skarn and vein; and...

Acoustic response of bats to the Brood X Periodical Cicada (Magicicada spp.) emergence Acoustic response of bats to the Brood X Periodical Cicada (Magicicada spp.) emergence
Periodical cicada emergences can positively affect vertebrate reproduction and breeding behavior, yet this response is not well studied for bats. We examined the acoustic response of 6 species/phonic groups of bats in 2021 to the emergence of Brood X periodical cicadas, along the Potomac River corridor, in Maryland and Virginia. Using a before-after-control-impact study design, we...

Deformation mechanisms in quartz veins and shear zones elucidate the origin of gold mineralization at Pogo, Alaska Deformation mechanisms in quartz veins and shear zones elucidate the origin of gold mineralization at Pogo, Alaska
Pogo is a quartz vein hosted, ca. 8 Moz gold deposit. Although it has similarities to orogenic and magmatic-hydrothermal deposits, its origin remains enigmatic. Observations from surface exposures, underground workings, and drill core provide new constraints on quartz vein origins with implications for mineralization. Abundant, largely barren metamorphic segregation quartz veins are...

Testicular neoplasms and other abnormalities in common carp Cyprinus carpio from the Lower Colorado River, United States Testicular neoplasms and other abnormalities in common carp Cyprinus carpio from the Lower Colorado River, United States
Abnormalities were observed in the testes of common carp Cyprinus carpio collected from Willow Beach, Arizona, USA, a site on the lower Colorado River, downstream of Lake Mead and Hoover Dam. Testicular tissue collected from this site in 2003 exhibited numerous large, pigmented macrophage aggregates (MAs) and a novel, previously undescribed hypertrophy and proliferation of putative...
