Deep subsurface organic-rich shale supports abundant, diverse, and novel fungi Deep subsurface organic-rich shale supports abundant, diverse, and novel fungi
As Earth’s principal reservoir of organic carbon and microbial biomass, the deep subsurface hosts microorganisms capable of mobilizing this once-sequestered carbon. Contrary to standard assumptions of eukaryotic scarcity, this study documents abundant fungal communities, ranging from 4.2 × 103 to 6.8 × 103 fungal cells mL−1, across a methane-producing organic-rich shale 247–556 meters...
Streamflow and surface-water presence data availability across the conterminous United States: A review for headwater systems Streamflow and surface-water presence data availability across the conterminous United States: A review for headwater systems
Water is essential for life on Earth, supporting ecosystems, human health, and economic activities. Hydrology relies on observational data, and this paper discusses regional and national datasets for the conterminous United States (CONUS) publicly available as of 2023, focusing on headwaters, defined as first- and second-order streams at 1:24000 scale. It identifies 72 primary and...
Spatial and temporal drivers of variability in abundance of two stream fishes Spatial and temporal drivers of variability in abundance of two stream fishes
An understanding of how and why animal populations vary in space and time informs effective conservation and management. We used spatial and temporal flow metrics to explore flow-ecology relationships for two fish species, Mountain Sucker Pantosteus platyrhynchus (Cope, 1874) and Mottled Sculpin Cottus bairdii Girard, 1850, across 64 sites and 8 years in Wyoming, U.S.A. We found...

Site Assessment and Monitoring of Constructed Wetlands in Montana
The Montana Department of Transportation (MDT) occasionally causes disturbance to wetlands during construction. To comply with Federal, State, and Tribal regulations, MDT creates replacement wetlands to compensate for wetland loss. The U.S. Geological Survey (USGS) collaborates with MDT to assess potential wetland replacement sites and monitor water conditions at established replacement sites...
Assessing the effects of mining on the Transboundary Koocanusa Reservoir
The Kootenai River Watershed is an international resource cooperatively managed by the U.S., Canada, and Tribal governments. In recent years, coal mining in the Canadian portion of the watershed has resulted in elevated concentrations of several constituents, including selenium, nitrate, and sulfate downstream (Storb et al., 2023). At increased levels, these mining byproducts can affect water...
Monitoring Changes in Groundwater Quality at Jackson Hole Airport
USGS studies revealed that aircraft deicing fluids from Jackson Hole Airport negatively affected the water quality of the Snake River aquifer in northwestern Wyoming (Wright, 2013). In response, the airport implemented improved deicing management and infrastructure. A recent USGS study determined that the airport’s changes likely contributed to improvements in aquifer groundwater quality (Wright...
