Rank purchase regarding kinds fullness into web sites remained an equivalent apart from Solon Prairie, and therefore diminished several cities inside relative rank, appearing nothing effectation of sampling efforts to the types richness.

Efficiency

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 kissbrides.com pogledaj the plants on which bees were caught were herbaceous perennials or shrubs, except for one annual species (Melilotus alba L.).
