The data document the results of several microbe bioassays performed by the USGS on Phragmites australis plants, including those performed on mature leaves, seedlings, and dead leaf tissues exploration of the literature to find accounts of microbes associated with Phragmites worldwide. For the bioassays, we prepared 162 pure cultures isolated from Phragmites plants in North America along the east coast, Florida, the Gulf of Mexico, and the Great Lakes area, 125 of which were from a previous study, and 38 represent new collections. The DNA sequences used to identify the 37 new collections are included. Microbes were isolated from plants collected from 2015-2018. We performed assays using both North American plant...
Vascular plant data collected at the South Unit of Theodore Roosevelt National Park, ND, USA in 1996
This data release contains three data sets. The data were collected in 1996 at the South Unit of Theodore Roosevelt National Park, ND, USA. The main data set comprises the list of plant species observed and includes the transect, plot number, plot size, and vegetation type where each species was found. A second data set has the locations of the transects, along with their IDs which can be linked to the species list. The final data set is a list of nomenclature updates and species that had duplicates in ITIS, along with the currently accepted scientific names of these species.

This data set consists of data collected during 2005-2007, 2010, and 2015 at Neal Smith National Wildlife Refuge in Iowa, USA that were used in the analysis in support of the article titled "Toward improving pollinator habitat: Reconstructing prairies with high forb diversity," which has been submitted to Natural Areas Journal. We compared pollinator habitat, in terms of planted forb richness, cover, and phenology, cover of planted grasses, and persistence of exotic species 10-years post-planting of reconstructions with 58 species (extra-high), 34 species (high), 20 species (medium) and 10 species (low) planted at the same time using the same fields, methods, and overall seeding rate. Twelve replicates of three...
This data set consists of data collected during 2012 in Badlands National Park in South Dakota that were used in the analysis in support of the PLOS One article titled "Exotic plant infestation is associated with decreased modularity and increased numbers of connectors in mixed-grass prairie pollination networks". The data consist of three spreadsheets. An insect richness, interactions, and flower count data set is a summary of counts of individual flowers (by species) and insects captured on flowers (that were found to carry pollen) over the course of a study on the effects of infestation by Cirsium arvense on pollinator interactions with native plants. Three dominant exotic plants, C. arvense, Convolvulus arvensis,...

USGS personnel surveyed bumble bees and flowering plants on private and public lands in Central Montana. These data provide a summary of what was found, including the number of bumble bees caught during standardized netting surveys and a comprehensive list of all plants in flower within survey plots during each site visit.

USGS personnel surveyed bumble bees and flowering plants in and around Glacier National Park during the summer of 2023. These data include 1) a .csv file of all bumble bee - plant interactions observed across surveys and 2) all flowering plants observed in bloom across all surveys.

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).
Plant roots have the best-understood mutualisms with microbes, but leaf and bract cell endosymbiosis have not been previously reported. Leaf and bract cells of more than 30 species in 18 families of seed plants were surveyed for the presence of intracellular bacteria and several experiments were designed to find and analyze nutrient exchanges between bacteria and plant cells. This dataset contains the results of 1) histochemical analyses to detect hormones, superoxide, and nitrogenous chemicals around bacteria within plant leaf and bract cells, 2) experiments to assess the differential absorption of isotopic nitrogen into plants, and 3) genetic analysis of bacteria isolated from plant material.
