Eriogonum visheri (Visher's buckwheat) seed, pollen, and insects at Badlands National Park, South Dakota, USA, 2014-2015, 2017 Eriogonum visheri (Visher's buckwheat) seed, pollen, and insects at Badlands National Park, South Dakota, USA, 2014-2015, 2017
This data record contains fitness data for Visher's buckwheat (Eriogonum visheri) for the years 2014, 2015 and 2017 at Badlands National Park, South Dakota, USA. These data include insect visitation, pollen deposited on stigmas, achene size and germination over three field seasons (two field seasons for germination: 2015 and 2017) in four populations (two populations in 2017).
County-Level Geographic Distributions for 47 Exotic Plant Species in Midwest USA and Central Canada, Compiled 2019 County-Level Geographic Distributions for 47 Exotic Plant Species in Midwest USA and Central Canada, Compiled 2019
Geographic distribution data were collected based on county level occurrences (or converted from point occurrences to county level occurrences) within the five focal states (Minnesota, North Dakota, South Dakota, Nebraska & Iowa) and each U.S. state or Canadian province bordering those focal states (Wisconsin, Illinois, Missouri, Kansas, Wyoming, & Montana in the USA and Saskatchewan...
Historical Length, Weight, and Fecundity of Silver Chub (Macrhybopsis storeriana) in Western Lake Erie Historical Length, Weight, and Fecundity of Silver Chub (Macrhybopsis storeriana) in Western Lake Erie
This data set provides a table of length, weight, sex, and estimated fecundity of Silver Chub Macrhybopsis storeriana in western Lake Erie from 1979 through 1987. These data are potentially useful to those studying recovery and restoration of Silver Chub in Lake Erie. These data were collected as part of routine trawl surveys in western Lake Erie. Other data associated with these data...
The Basin Characterization Model - A monthly regional water balance software package (BCMv8) data release and model archive for hydrologic California (ver. 5.0, June 2025) The Basin Characterization Model - A monthly regional water balance software package (BCMv8) data release and model archive for hydrologic California (ver. 5.0, June 2025)
This data release accompanies the USGS Techniques and Methods report titled: "The Basin Characterization Model - A Regional Water Balance Software Package", and includes all necessary Basin Characterization Model version 8 (BCMv8) inputs and outputs for water years 1896 to 2024. The BCMv8 was refined from the previous BCMv65 version to improve the accuracy of the water-balance components
Lake Erie Aquatic Vegetation data Lake Erie Aquatic Vegetation data
Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic...
