Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022 Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022

This dataset is associated with an examination of environmental DNA (eDNA) obtained from freshwater matrices (i.e. benthic algae, sediment, and near bottom water) collected by scuba divers from previously established transects located along the U.S. shoreline of Lakes: Michigan, Huron, Erie, and Ontario. 16S rRNA gene amplicon sequencing (i.e., targeting bacterial communities) and high...

Benthic Algal Community Composition in the Laurentian Great Lakes (2024) Benthic Algal Community Composition in the Laurentian Great Lakes (2024)

This data set includes information on benthic algae community composition collected during the growing season of 2024 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. Benthic algal community observations were taken by scuba divers in the field and by personnel in the lab during sample processing, including detailed microscopic examination of...

Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022 Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022

This dataset includes three datasets collected in 2021 and 2022 to assess the potential effects of bison (Bison bison) herbivory and climate on grassland functional properties throughout semi-arid meadows in Grand Canyon National Park and Kaibab National Forest of northern Arizona. Bison herbivory offtake (utilization) and aboveground herbaceous production are demonstrated in the...

Historical and projected future land change and ecosystem carbon stocks for California Historical and projected future land change and ecosystem carbon stocks for California

This dataset consists of annual raster maps of ecosystem carbon stocks, land use and land cover classes, and transition probabilities for the State of California during historical (1985-2020) and projected future (2021-2100) time periods. Data are simulation model output from the The Land Use and Carbon Simulator (LUCAS; Sleeter et al. 2022) run under different future climate and land...

Model Archive Summary and Time-Series Suspended-Sediment Concentrations Computed from a Surrogate Turbidity Regression at U.S. Geological Survey Station 11455420; Sacramento River at Rio Vista, California (2020 - 2023) Model Archive Summary and Time-Series Suspended-Sediment Concentrations Computed from a Surrogate Turbidity Regression at U.S. Geological Survey Station 11455420; Sacramento River at Rio Vista, California (2020 - 2023)

Continuous 15-minute time-series suspended-sediment concentration (SSC) data computed from California Department of Water Resources (CDWR) instream turbidity data with a YSI EXO multi-parameter water quality sonde. A Model Archive Summary (MAS) describes the development of a continuous 15-minute SSC time-series regression model.

GPS Locations of Free-roaming Burros in Utah and Arizona, USA, 2016 to 2020 GPS Locations of Free-roaming Burros in Utah and Arizona, USA, 2016 to 2020

This dataset includes locations of burros between 2016 and 2020 from two study areas where burros were located every 2 hours continuously using GPS telemetry collars for Lotek collars, and every 13 hours continuously for Vectronic Aerospace collars. Location data are from adult female burros, not males. Study areas are the Lake Pleasant Herd Management Area in Arizona, USA and the Sinbad...

Data Describing Effects of Telemetry Collars on Horses and Burros Between 2016 and 2020 Data Describing Effects of Telemetry Collars on Horses and Burros Between 2016 and 2020

This dataset includes a number of datasets collected to assess the potential effects of GPS telemetry collars on free-roaming feral equid species in North America: horses and burros. The behavior dataset (Behavioral_data_collared_uncollared.csv) includes frequency of maintenance behaviors of collared and un-collared horses at Conger Herd Management Area (HMA), and burros at Lake Pleasant...

Data describing species consumed by mountain lions during predation events in eastern Nevada, USA, 2018 to 2022 Data describing species consumed by mountain lions during predation events in eastern Nevada, USA, 2018 to 2022

This dataset consists of 1,353 ground observer investigations of mountain lion predation events ("kills") in eastern Nevada, USA, from 2018 to 2022. Over the period of the data collection, we had 29 mountain lions equipped with telemetry collars and we investigated clusters of locations when GPS collar locations were in the same area for three nights -- we used this criteria to identify...

Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA Data on behavior of adult horses and burros between 2016 and 2020, in Utah and Arizona, USA

We investigated the behavior of feral horses (Equus caballus) at Conger Herd Management Area (HMA), UT, and of burros (Equus asinus) at Lake Pleasant HMA, AZ, and Sinbad HMA, UT between 2016 and 2020 (Sinbad HMA 2016 to 2019; Conger and Lake Pleasant HMAs 2017 to 2020). We collected data on the time budget and social behavior of adults (2 years old and older) between April and September...

Nesting Duck Populations in Suisun Marsh, California Nesting Duck Populations in Suisun Marsh, California

This dataset includes apparent nest density (observed nests per hectare of area searched) of mallard (Anas platyrhynchos) and gadwall (Mareca strepera) in Suisun Marsh, California.

Waterbird Nest Abundance in South San Francisco Bay Waterbird Nest Abundance in South San Francisco Bay

This dataset includes nest abundance of American avocets (Recurvirostra americana), black-necked stilts (Himantopus mexicanus), and Forster's terns (Sterna forsteri) in south San Francisco Bay, California by year. It also contains California gull (Larus californicus) hazing research efforts. This dataset was generated from yearly nest monitoring surveys within wetlands in south San...

Habitat Features and Waterbird Abundance and Diversity on Managed Wetlands Enrolled in the California Waterfowl Habitat Program Habitat Features and Waterbird Abundance and Diversity on Managed Wetlands Enrolled in the California Waterfowl Habitat Program

This dataset includes wetland habitat measurements, surrounding land cover metrics, and waterbird abundance and diversity during 240 surveys of 117 individual wetland units enrolled in the California Waterfowl Habitat Program. This dataset was generated from wetland surveys conducted in the Sacramento Valley, San Joaquin Valley, and Suisun Marsh in 2022 and 2023.
