Body condition scores and foaling outcomes in 2021 for 18 mares at Sulphur herd management area, Utah treated with gonadotropin releasing hormone Body condition scores and foaling outcomes in 2021 for 18 mares at Sulphur herd management area, Utah treated with gonadotropin releasing hormone
These data present outcomes for monitoring of 18 mares at Sulphur herd management area, Utah. Data include Henneke body condition scores (BCS) and foaling success, measured by visual observations of mares during the 2021 breeding season (April to September 2021) to determine if mares had a foal at foot. Mares were treated with gonadotropin releasing hormone vaccine on September 2, 2020...
Specimen observation data for Najas marina L. from 1863 to 2020 Specimen observation data for Najas marina L. from 1863 to 2020
The North American distribution of Najas marina L. from 1863 to 2020 is presented in this dataset. Fields provided include georeferenced coordinates, dates of collections, collectors, and source herbaria. Data are housed in the U.S. Geological Survey's Nonindigenous Aquatic Species Database (nas.er.usgs.gov).
Estimated equivalent population using groundwater for public supply domestic use in the conterminous U.S. 2010, hydrogeologic mapping units, and wells used (ver. 2.0, March 2023) Estimated equivalent population using groundwater for public supply domestic use in the conterminous U.S. 2010, hydrogeologic mapping units, and wells used (ver. 2.0, March 2023)
These datasets map the estimated population using public supply drinking water (both groundwater and surface water) using two methods: the census enhanced method (CEM) evenly distributes the population across populated census blocks, and the urban land-use enhanced method (ULUEM) distributes the population only to certain urban land use designations. (See the six Estimated equivalent...
Data on grasshopper composition in the Thunder Basin National Grassland, Wyoming, USA Data on grasshopper composition in the Thunder Basin National Grassland, Wyoming, USA
Grasshopper biomass and species-level diversity was recorded at locations on and off prairie dog colonies in the Thunder Basin National Grassland, Wyoming, USA. Data were collected in order to record the association between grasshopper communities and prairie dog colonies.
Flood inundation map geospatial datasets for Lake Ontario, New York Flood inundation map geospatial datasets for Lake Ontario, New York
Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https:/...
Dissolved oxygen concentrations, light penetration, and temperature along the water-depth profile of wetlands P1 and P8 of the Cottonwood Lake Study area in North Dakota, USA, 2019 Dissolved oxygen concentrations, light penetration, and temperature along the water-depth profile of wetlands P1 and P8 of the Cottonwood Lake Study area in North Dakota, USA, 2019
This data release presents data that were collected as part of a larger effort to assess factors that regulate metabolism in global lakes, via an international collaboration with the Global Lake Ecological Observatory Network (GLEON). From May to August 2019, dissolved oxygen and light penetration were measured throughout the water-depth profile of two small inland wetlands at Cottonwood...
