Range day testing prejudice was checked by evaluating mentioned variety fullness away from internet sites that have rarefacted kinds fullness. Regarding rarefaction analysis, we place attempt size on dos1 some one, that below the minimum count discovered at this site having the fresh fewest bumble bees. Review buy regarding varieties fullness with the web sites stayed a comparable apart from Solon Prairie, and therefore reduced a couple of urban centers inside cousin review, demonstrating absolutely nothing aftereffect of sampling energy on varieties fullness.
Overall performance
Species richness ranged from five to eight species per site, and log2 Shannon-Wiener diversity across the eight sites ranged from 2.05 to 2.69. Five species common to all sites were B. bimaculatus Cresson, B. impatiens Cresson, B. pensylvanicus (DeGeer), B. auricomus (Robertson), and B. griseocollis (DeGeer), but the abundance of individuals among bumble bee species differed greatly between sites ( Fig. 1). We observed bumble bees on 43 of the 150 flowering species found at the sites. The percentage of native plant species among the 43 species visited was similar to their overall percentage in the combined flora of the sites (80 versus 77%, respectively). All of the plants on which bees were caught were herbaceous perennials or shrubs, except for one annual species (Melilotus alba L.).
