The release of metals (or metalloids) to surface water can involve both natural and anthropogenic sources. Elevated metals concentrations can pose a risk to human health, wildlife, and ecosystem health, with the modes of toxicity and extent of risk varying as a function of the specific metal, its chemical form and the matrix with which it is associated (for example, dissolved versus...

This data package includes a high-water shoreline position map and a structures map for each year from 2016–2019 for the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish using material dredged...

This data package includes a high-water shoreline position map and a structures map for each year from 2016–2019 for the National Fish and Wildlife Foundation (NFWF) Caminada Headland Beach and Dune Restoration Incr2 project area (BA-0143). The project restored 489 acres of beach and dune habitat along more than seven miles of Caminada Headland in Jefferson and Lafourche Parishes through...

We evaluated brood-rearing habitat selection and brood survival of greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) in Long Valley, California, an area where the water rights are primarily owned by the city of Los Angeles and water is used locally to irrigate for livestock. This area thus represents a unique balance between the needs of wildlife and people that...

Recent advances in hydroacoustic technology are proving to be valuable tools for mapping habitat features for sedentary biota such as freshwater mussels, and has the potential to identify and quantify habitat features. The Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) are imperiled mussels that are typically associated with rock structures (e.g., wing dams...

The software consists of three scripts to be run in the R statistical program: 1) Alligator growth simulation; 2) alligator integrated population model file; and 3) data visualization script. Script #1 produces growth transition probabilities that are used in script #2. The second script uses the outputs from #1 as well as other data files to run an integrated population model. The last...

This is code for an integrated population model developed to understand the effect of horseshoe crab abundance on population demographics of red knot, an Arctic-breeding shorebird. This model was developed as part of the revision to the Atlantic States Marine Fisheries Commission Adaptive Resource Management Plan for horseshoe crabs.

California's State Water Resources Control Board (SWRCB) wishes to quantify how water and constituents introduced via the outflow from the Spring Creek Diversion Dam mix with water within Keswick Reservoir. Of primary interest is the degree of dilution that exists when this introduced flow reaches the main stem of Keswick Reservoir, and how this mixing is influenced by different...

The Aga, also known as the Mariana Crow, is an endangered endemic crow of the Northern Mariana Islands, a Commonwealth of the United States of America. The only known population currently extant is on the island of Rota and has been in decline over the past two decades. Unknown pathogens are among the factors that may be contributing to this decline. To support metagenomic and...

These data were collected to understand the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in the middle Chickahominy River watershed. Specifically, this effort was initiated to: 1. Determine concentrations of PFAS in surface water at select locations in the middle Chickahominy River watershed; 2. Determine concentrations of PFAS in edible portions of fish at select locations...

The data details common loon locations based on archival geolocator tag information, characteristics of common loon dives during wintering, and common loon locations based on telemetry data. Satellite transmitters (Model PTT-100, Microwave Telemetry, Inc) were implanted in 31 adult male (marked during July 2010 and July 2011) and 27 juvenile (marked during August 2014 and August 2015)...

These data were compiled to provide seed transfer and native plant materials development guidance to managers and practitioners across the Colorado Plateau and in adjacent regions. This data release contains empirical seed transfer zones derived from molecular genetic data for Cleome serrulata (syn. Peritoma serrulata), Heliomeris multiflora, and Astragalus lonchocarpus. These species...
