Exotic plant infestation is associated with decreased modularity and increased numbers of connectors in mixed-grass prairie pollination networks data set

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". 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, and Melilotus officinalis are tallied separately. The insect species richness and interactions were tallied for native and minor exotic plant species. A pollen carrier data set includes all insects captured on flowers that were either bees, or were found to carry pollen, at the 12 study plots. The insect can be recorded more than once if it was captured on one species of flower, but carried pollen from other species. The third data set contains latitude and longitude coordinates for the 12 study plots.
