Gene flow and spatial population structure of Brook Trout in a large headwater stream network in Colorado
We studied gene flow of non-native Brook Trout Salvelinus fontinalis in a 60-km section of continuous stream network in the upper Cache la Poudre River basin, where a large-scale reclamation effort to restore federally threatened Greenback Cutthroat Trout Oncorhynchus clarkii stomias (GBCT) is taking place. This effort—the Poudre Headwaters Project—represents the most important recovery effort of

Conservation genetics and wild trout: Evolving opportunities to support management
It is increasingly apparent that our planet is undergoing rapid, unprecedented environmental change. These changes are already impacting wild trout populations, leading to declines in occupancy and abundance across increasingly fragmented landscapes. Many changes are projected to intensify in the coming decades, which are likely to be crucial to the future of many wild populations. While there is

Benefits of genetic data for the design of Brook Trout translocation efforts
With wild trout populations in decline, many conservation practitioners are evaluating the feasibility of incorporating reintroduction and genetic rescue into management frameworks. As interest in these conservation tools continues to grow, so too has the need for rigorous science to evaluate translocation success and improve the efficacy of future efforts. From this, it has become increasingly ap

Preliminary national-scale seismic risk assessment of natural gas pipelines in the United States
Although the gas pipeline infrastructure in the United States is vulnerable to the seismic hazards of (i) strong ground shaking, and (ii) ground failures induced by surface faulting, liquefaction, or landslides, limited national guidance exists for operators to consistently evaluate the earthquake response of their pipelines. To provide additional information for stakeholders and establish more co

Assessing direct and indirect long-term economic impacts from earthquakes to the U.S. National Bridge Inventory
Using the 2018 National Seismic Hazard Model and the 2018 National Bridge Inventory, an annualized earthquake loss (AEL) study was conducted for approximately 610,000 bridges in the conterminous United States, quantifying both direct and indirect economic losses. The typical AEL framework has been augmented with new replacement unit cost data and bridge-specific parameters for modifying default fr

Economic consequences of the HayWired earthquake scenario
This study evaluates the economic impacts of a Mw7.0 Hayward fault scenario earthquake on the greater San Francisco Bay Region’s economy and the California economy as a whole using a detailed multiregional, static computable general equilibrium model. Economic impacts in terms of Gross Regional Product (GRP) losses caused by both capital stock (building and content) damages and water and electrici

Applying consequence-driven scenario selection to lifelines
We present a new consequence-driven framework for earthquake scenario selection. For emergency managers, utility operators, policy makers, and other stakeholders, a scenario-based seismic risk assessment is often necessary for the purpose of emergency management and planning. In developing a scientifically defensible scenario, stakeholders can simulate a realistic event in order to pre-identify vu

Assessing global geologic carbon dioxide storage resources
The U.S. Geological Survey (USGS), in conjunction with the U.S. Department of Energy (U.S. DOE) Office of Fossil Energy and Carbon Management (FECM), the IEA Greenhouse Gas R&D Programme (IEAGHG), and the Clean Energy Ministerial Carbon Capture, Utilization and Storage Initiative (CEM-CCUS Initiative), plans to work with partner nations to assess geologic carbon dioxide (CO2) storage resources glo

It’s time for focused in situ studies of planetary surface-atmosphere interactions
A critical gap in planetary observations has been in situ characterization of extra-terrestrial, present-day atmospheric and surface environments and activity. While some surface activity has been observed and some in situ meteorological measurements have been collected by auxiliary instruments on Mars, existing information is insufficient to conclusively characterize the natural processes via con

Repeat bathymetric surveys and model simulation of sedimentation processes near fish spawning placements, Detroit and St. Clair Rivers, Michigan
Nine rock-rubble fish spawning placements, or artificial reef complexes, constructed in the
Detroit and St. Clair Rivers between 2004 to 2018 were surveyed periodically with multibeam
sonar. These serial bathymetric surveys, conducted in 2015, 2018, 2021, and 2022, identified
active sand bedform fields impinging two reef complexes: Fighting Island in the Detroit River
and Middle Channel in the

Lateral moraines, ice-dammed lakes, and meltwater-carved channels in the Pelham, Shutesbury, Leverett area of west-central Massachusetts: A record of Connecticut Valley ice lobe retreat
Temporary ice-dammed glacial lakes formed high in the landscape in several westward sloping valleys on the east side of the Connecticut Valley lowland during late Wisconsinan deglaciation. These lakes were impounded by a lengthy lobe of ice that extended farther south in the lowland than at upland retreatal ice-margin positions (fig. 1). The formation, lowering, and drainage of these ice-dammed la
