Honey bees and wild pollinators differ in their preference for and use of introduced floral resources

The dataset was collected in two phases. First, in 2017, data was collected on visitaiton rates and diversity of pollintors visiting plants in three meadows in upstate New York. Data was collected throughout the flowering period. Please see the publication for details on data collection. Second, in 2018, data was collected on knapweed pollen and nectar collection in 22 apiaries across New York. Each apiary was visited twice, nectar and pollen samples were taken from two hives per apiary. For each sample, we counted the number of knapweed pollen grains per 300 total grains in a subsample of the substrate (nectar or pollen). Also, in 2018, we collected insects visiting knapweed in 7 fields across New York. Please see the publication for details on data collection.
