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...
