,Data files for manuscript titled "A checklist of South Dakota bumble bees (Hymenoptera: Apidae) ", https://doi.org/10.3897/jhr.94.94584.,Excel file with 4 tabs: Metadata, county maps, species data, and species matrix. Metadata is contained within Excel file that describes all variables for each tab.,Abstract from paper: Several bumble bee species (Bombus Latreille) are declining and efforts to conserve populations will be strengthened by an improved knowledge of their geographic distribution. Knowledge gaps exist, however, especially in central portions of North America. Here we report 29 species of bumble bees from South Dakota in the north-central USA, based on 130 years of records from 1891 to 2021. Specimens or observations were available for >90% of the 66 counties, though they were not distributed evenly as most records came from Pennington, Lawrence, Custer, Brookings, and Day Counties. The five most commonly collected or reported bumble bee species were B. griseocollis (54 counties), B. pensylvanicus (41 counties), B. fervidus (39 counties), B. huntii (27 counties), and B. bimaculatus (25 counties). Twenty species were recorded from 10 or fewer counties. Despite differences in occurrence, 66% of the Bombus species in South Dakota were collected or observed since 2020, including six of the nine species of conservation concern (B. fraternus, B. pensylvanicus, B. fervidus, B. occidentalis, B. terricola, and B. morrisoni). However, the critically endangered B. affinis, B. variabilis, and B. suckleyi have not been collected or observed for over 50 years. While this checklist is the first for South Dakota bumble bees in nearly 100 years, data are still lacking as ~55% of counties had fewer than five species reported. We suggest future efforts should focus on these under-sampled areas to fill in baseline knowledge of the wild bee fauna towards completing a more holistic view of bumble bee distributions across the Great Plains.,,

We measured nesting rates and nesting success for a community of cavity-nesting bees across gradients of floral abundance, floral richness, and land-cover in the Prairie Pothole Region. Variables in this dataset include a unique transect identifier, a count of the occupied nests per transect, total floral species richness per transect, total floral stem abundance per transect, bee species richness, number of emerged adult bees per transect, and the proportion of those emerged bees which were female. In addition, there are land-cover measurements of the total area, in hectares, of grasslands, wetlands, and woodlands within 500m and 1500m of each transect. We binned land-covers from the 2019 National Agricultural Statistics Service Cropland Data Layer into our definitions of grasslands (Other Hay/Non Alfalfa, Sod/Grass Seed, Fallow/Idle Cropland, and Grassland/Pasture), wetlands (Woody Wetlands and Herbaceous Wetlands), and woodlands (Deciduous Forest, Evergreen Forest, and Shrubland).

This dataset consists of data collected at Badlands National Park (Interior, SD) that were used in the analysis in support of the article titled "Conserving all the pollinators: Variation in probability of pollen transport among insect taxa," which has been submitted to "Natural Areas Journal." Data collected between May-October, 2010 and 2011, and June-July 2012 included insects found in contact with floral reproductive parts of focal plant species, or plant species within a 1 ha plot surrounding focal plant, and pollen species removed from the collected insects' bodies. Focal plant species included Astragalus barrii (May-June 2010-11), Eriogonum visheri (July-August, 2010-11), Chrysothamnus parryi (September-October 2010-11) and Cirsium arvense (June-July 2012).

Bumblebee community surveys used occupancy survey designs primarily across lands managed by the Bureau of Land Management (BLM) and Glacier National Park (GNP). They also include a few surveys in Nevada. These records represent timed surveys that were both successful and unsuccessful in detecting bumble bees.
