Mallard migration and regional movement timing, distance, and direction data, 2018–2020 Mallard migration and regional movement timing, distance, and direction data, 2018–2020
The mallard (Anas platyrhynchos) is an abundant and wide-spread duck species that exhibits considerable variation in migratory behavior due to a relatively large body size and behavioral plasticity in habitat use. Understanding migration and other movements of mallards has societal interest in a wildlife management context because mallards are a preferred species of waterfowl by hunters...
Data from Assessing the added value of antecedent streamflow alteration in modelling stream condition Data from Assessing the added value of antecedent streamflow alteration in modelling stream condition
The dataset contains long-term and short-term summaries of streamflow alteration and measures of biological condition (fish multi-metric index). Streamflow alteration metrics include the magnitude, duration, frequency, and seasonality of high and low flow streamflow. Biological condition was estimated from the National Rivers and Streams Assessment and National Water Quality Assessment...
Data Supporting Analysis of Relations Between Nutrient Concentrations in the Herring River on the Ebb Tde, Near Wellfleet, Massachusetts and Environmental Conditions, 2015- 2022. Data Supporting Analysis of Relations Between Nutrient Concentrations in the Herring River on the Ebb Tde, Near Wellfleet, Massachusetts and Environmental Conditions, 2015- 2022.
This data release supports analyses of the relations between monthly average nutrient concentrations in the Herring River on the ebb tide near Wellfleet Massachusetts and monthly average precipitation, temperature, runoff, solar radiation, ocean water temperature, mean sea level, nutrient concentrations in Wellfleet Harbor, and atmospheric deposition of nitrogen 2015-2021. The...
Movements, Used Habitats, and Available Habitats Identified using Step Selection Processes for Four Species of Waterfowl in California's Central Valley, 2016-2022 Movements, Used Habitats, and Available Habitats Identified using Step Selection Processes for Four Species of Waterfowl in California's Central Valley, 2016-2022
Step selection functions use animal movement patterns to estimate habitats available at each step along a movement track. These data were generated from four species of waterfowl (Anser albifrons [greater white-fronted goose], Anser caerulescens caerulescens [lesser snow goose], Anas platyrhynchos [mallard], Anas acuta [northern pintail]) using the Central Valley of California 2016 to...
Target-chemical concentrations and microbiological results in surface water and tapwater, Montana, 2022-23 (ver. 2.0, January 2026) Target-chemical concentrations and microbiological results in surface water and tapwater, Montana, 2022-23 (ver. 2.0, January 2026)
This data release contains the concentration and quality-assurance results for inorganic constituents, as well as organic compounds (volatile organic compounds [VOC], per- and polyfluoroalkyl substances [PFAS], pesticides and disinfection byproducts [DBP]) and microbiological results collected in the Little Big Horn River and residential or commercial tapwater locations in Montana...
Water chemistry data from the Big Creek and Monumental Creek tributaries of the Lower Middle Fork Salmon River, Idaho, 2021 Water chemistry data from the Big Creek and Monumental Creek tributaries of the Lower Middle Fork Salmon River, Idaho, 2021
This USGS data release evaluates the impact of historical mining sites on water quality using samples collected in late July 2021 from Big Creek tributaries Coin Creek, Smith Creek, and Monumental Creek in Valley County, Idaho. These data were collected to support a fisheries mining impact assessment in the Middle Fork Salmon River. Specific conductance, pH, and stream temperature were...
