dc.description.abstract | To examine changes in bee communities and bee–flower relations in the Prairie Pothole Region of the Northern Great Plains, we compared bee specimens and their floral associations collected in eastern North Dakota during 2010–2012 to bee specimens and their floral associations collected from the same region during 1910–1920 by pioneering naturalist Orin Alva Stevens. We also examined citizen science photographic records from 2012–2021. Using rarefaction, we found similar estimated bee species richness between the 1910s (135.98 ± 9.82) and the 2010s (125.42 ± 8.14). Bumble bees were less frequently present in collecting events in the 2010s, with one bumble bee species, Bombus terricola, declining from 7% presence in collecting events in the 1910s to 0.4% in the 2010s. Hylaeus annulatus, Andrena miranda, and Hesperapis carinata were each in the top 25% of species most frequently present in collecting events in the 1910s but were absent in the 2010s. Citizen science images documented range expansions for Bombus impatiens and the non-native Anthidium manicatum. Based on the floral association data, we recommend that pollinator plantings include (1) flowers that were formerly common in bee association records but that had decreased presence or were absent from modern collections and (2) flowers visited by possibly declining bee species, as indicated by historic flower associations for bee species that were absent or less frequently present in modern collecting events. The persistence of many bee species, including those of conservation concern, in agriculturally dominated landscapes points to the importance of restoring key floral resources to wide-ranging habitats. | |
