American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling, and anesthesia) with few to no premonitory clinical signs. Two cases died due to infection: one had bacterial pyogranulomatous dermatitis, cellulitis, and lymphadenitis with sepsis; the other case had fungal necrotizing colitis. Incidental parasite infections included sarcocystosis, nematodiasis (oxyurids), and ectoparasitism. Most...

These data describe the results of virus isolation from oropharyngeal/cloacal swabs and testing of sera by a commercial blocking enzyme-linked immunosorbent assay (bELISA) and hemagglutinin (HA) specific testing by microneutralization (MN) and hemagglutination inhibition (HI) for Lesser Scaup in both the Atlantic and Pacific Flyways and Greater Scaup in the Pacific Flyway. These data support a USGS published manuscript.

These two datasets contain metrics from hydrodynamic and particle tracking simulations for two sub-reaches of the Upper Missouri River near Wolf Point, MT. The upstream reach is referred to as the “upper” reach while the downstream reach is referred to as the “lower” reach. Simulations were performed for 16 flows in the range of 185-635 cms at increments of 30 cms.
Continuous water-temperature data were collected at multiple sites along the Middle Fork and mainstem Willamette Rivers between Jasper and Newberg, Oregon, to support effectiveness monitoring for a large-scale channel and floodplain restoration program (Willamette Focused Investment Partnership, WFIP). Continuous water temperature loggers were deployed at a subset of WFIP restoration sites where river restoration activities were implemented to improve habitat conditions for native fish species. Data from water-temperature monitoring will be used to evaluate the effectiveness of restoration activities at improving habitat conditions for ESA-listed salmonids and other native fish in the Willamette River. Additionally,...

This metadata record documents a set of 118 comma delimited files and a data dictionary describing the inputs for the U.S. Geological Survey Precipitation Runoff Modeling System (PRMS) which is used to drive the National Hydrologic Model (NHM) for the United States-Canada transboundary domain. The National Hydrologic Model database contains parameters for hydrologic response units (HRUs) and stream segments needed to run the NHM. These parameters are generated using python scripts to process input datasets such as digital elevation models, soil maps, and land cover classifications. Many of the parameters were left at their default model value as they would need to be calibrated as part of the PRMS model development...

The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand by delivering routine assessments of water supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface water quantity, quality, and use. This data release contains Mann-Kendall monotonic trend analyses for annual groundwater metrics at 39,964 wells located in the conterminous United States, Alaska, Hawaii, and Puerto Rico. The groundwater metrics include annual mean, maximum, and minimum water level and the timing of the annual...

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States' coasts from both older sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the USGS Digital Shoreline Analysis System (DSAS), version 5.1 software to calculate rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated...

This metadata record describes monthly estimates of natural baseflow for 15,866 stream reaches, defined by the National Hydrography Dataset Plus Version 2.0 (NHDPlusV2), in the Delaware River Basin for the period 1950-2015. A statistical machine learning technique - random forest modeling (Liaw and Wiener, 2018; R Core Team, 2020) - was applied to estimate natural flows using about 150 potential predictor variables (Miller and others, 2018). Calibration data used for the random forest model are available from (Foks and others, 2020). Each model was run twice, first using all potential predictor variables, which represents a "full" model run, and a second time using the top 20 predictors from the original run, which...

This U.S. Geological Survey (USGS) data release consists of two hydrographic datasets with spatial modeling units, two sets of spatial data consistent with the National Hydrologic Model (NHM) Geospatial Fabric for National Hydrologic Modeling (abbreviated within this document as GFv1, Viger and Bock, 2014), and a database of 118 parameters used to run the NHM . These datasets are found as subpages to this landing page as 1) the GIS (geographic information system) features of the United States-Canada Transboundary Geospatial Fabric (TGF, added 08/04/2020), 2) the GIS features of the Geospatial Fabric v1.1 (GFv1.1 or v1_1, added 08/04/2020) which is an update to the GF and includes the TGF, 3) Topographic derivative...

The data in this data release are from an effort focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on definitions and metrics of resilience in water management institutions. Water resource managers, at various scales, are tasked with making complex and time-sensitive decisions in the face of uncertainty, competing objectives, and difficult tradeoffs. To do this, they must incorporate data, tacit knowledge, cultural and organizational norms, and individual or institutional values in a way that maintains consistent and predictable operations under normal circumstances, while...

Risk assessments describe the risk of a species’ invasion in a location, and many risk assessments have been produced by different institutions for various reasons. However, information is sporadically located online, increasing the difficulty of developing comprehensive lists of species with risk assessments or comparing assessment results across species in locations of interest. Therefore, we aggregated species risk assessments by searching information systems and conducting a literature review. The methods for data aggregation are explained in the larger work citation (Dean et al. 2024). The present dataset documents risk assessments available at different spatial scales (e.g., territory, state, region, nation)...

Anaerobic microcosm experiments were conducted in April-May 2018 with PFAS-contaminated soil from a U.S. Army installation (Fort Drum, New York) and simulated groundwater. All microcosms, except for a live sediment control, were amended with perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and 6:2 fluorotelomer sulfonate (6:2 FtS). Replicate treatments were prepared with and without bioaugmentation with the WBC-2 dehalogenating culture and with and without addition of chlorinated volatile organic compounds (1,1,2,2-tetrachloroethane and trichloroethylene). Two additional treatments were prepared containing granular activated carbon. All microcosms were prepared in duplicate and sacrificed for sampling....
This dataset contains breakthrough curves calculated from particle tracking simulations of a July 1, 2019, larval drift experiment conducted on the Upper Missouri River near Wolf Point, MT. Breakthrough curves were generated using a custom script written in the Python programming language that counts the number of particles per time step passing through sampling locations. Breakthrough curves were generated for particles using passive, active75pct, and active60pct vertical movement methods at the first two sampling stations downstream of the release location.
