This data release (DR) is the update of the U.S. Geological Survey (USGS) - ScienceBase (SB) DR Bera (2024b), with the processed data for the period October 1, 2022, through September 30, 2023. This SB DR describes the watershed data management (WDM) database WBDR23.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and...
Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024 Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024
This data set contains Lake Trout (Salvelinus namaycush) egg density estimates obtained from suction sampling across five locations in Lake Ontario. These data were collected in October-November 2020 and November-December 2024 as part of an effort to identify Lake Trout spawning locations and habitat preference in Lake Ontario. Additional information on habitat characteristics at each...
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...
