The objectives of the present study were to develop methods for propagating western pearlshell (Margaritifera falcata) for laboratory toxicity testing and evaluate acute and chronic toxicity of chromium VI [Cr (VI)] to the pearlshell and a commonly tested mussel (fatmucket, Lampsilis siliquoidea at 20°C or in association with a co-stressor of elevated temperature (27°C), zinc (50 µg Zn/L), or nitrate (35 mg NO3/L). A commonly tested invertebrate (amphipod, Hyalella azteca) was also tested in chronic exposures.

A probe-based quantitative real-time PCR assay was developed to detect Tetracapsuloides bryosalmonae, which causes Proliferative Kidney Disease in salmonid fish, in kidney tissue and environmental DNA (eDNA) water samples. We present data that was used to determine assay sensitivity, specificity and to define the limits of detection and quantification.

The National Contaminant Biomonitoring Program (NCBP), which was developed and maintained by the U.S. Fish and Wildlife Service (FWS), monitored concentrations of environmental contaminants in fish and wildlife over a period of about 20 years. Beginning in the 1960s as a component of the multi-agency National Pesticide Monitoring Program (NPMP) and continuing through the mid-1980s, fish and wildlife were periodically collected from a national network of stations for analysis of pesticides, PCBs, and other contaminants. The NPMP/NCBP database of contaminant concentrations is the most extensive of its kind, unique in its breadth and depth with respect to environmental contaminant concentrations. The data and information...

This dataset includes barrier island land cover types collected from mid-November 2015 to mid-December 2015 along randomly placed transects at seven sites throughout the east end of Dauphin Island. Specifically, this data collection included characterizing land cover types and measuring horizontal position and elevation. We characterized plant community composition and structure for a subset of these points (see Vegetation Survey Data Table). This work was conducted through a joint effort by the State of Alabama, the U.S. Geological Survey, and the U.S. Army Corps of Engineers to evaluate the feasibility of various restoration alternatives and how specific alternatives might increase the resiliency and sustainability...
This data release contains inputs for and outputs from hydrologic simulations of the southeastern U.S. using the Monthly Water Balance Model, the Precipitation Runoff Modeling System (PRMS), and statistically-based methods. These simulations were developed to provide estimates of water availability and statistics of streamflow for historical and potential future conditions for an area of approximately 1.16 million square miles. These model input and output data are intended to accompany a U.S. Geological Survey Scientific Investigations Report (LaFontaine and others, 2019); they include four types of data: 1) model input parameters, 2) model output statistics, 3) GIS files of the model hydrologic response units...
The project was conducted to study the effects of land management options. It was conducted across a regional network of sites in sagebrush communities. Using this regional network of sites allowed us to understand the thresholds between healthy and unhealthy sagebrush communities over a broad range of conditions across the Great Basin. Sites were located in sagebrush communities threatened by cheatgrass invasion, and we studied the effects of four land management options: control (no management action), prescribed fire, mechanical thinning of sagebrush by mowing, and herbicide application (to thin old, unproductive sagebrush plants and encourage growth of young sagebrush and native understory grasses). An additional...

Using data from 288 adult and yearling female elk that were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars, we fit Step Selection Functions (SSFs) during the spring abortion season and then implemented a master equation approach to translate SSFs into predictions of daily elk distribution for 5 plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). Here we provide the predictions of elk space use on a daily basis at a 500m resolution for the 5 different weather scenarios: 1) low snowfall year (2010), 2) average snowfall year (2012), 3) high snowfall year (2014), 4) hypothetical early snowmelt climate change scenario where spring green...
The grizzly bear distribution boundary delineates the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was generated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2000 to 2014.

We calculated mean adult and yearling female elk abundance for each Wyoming winter supplemental feedground subpopulation for data collected from 2009 to 2015. In addition, the average seroprevalence of brucellosis in elk attending feedgrounds was based on blood samples from adult and yearling female elk from 1993 to 2015. The sample size of disease tests and the number of years over which they were collected on each feedground are also listed. Serological profiles were categorized using the 2003 U.S. Department of Agriculture brucellosis eradication uniform methods and rules for cervids. These serological tests indicate whether or not an individual has been exposed, but not whether they are currently infected.

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Nate. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of potential new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017...
