Range time testing prejudice is actually checked from the evaluating mentioned types richness away from sites having rarefacted species richness. On the rarefaction analysis, i set try proportions within 21 anyone, you to less than the minimum amount discovered at the site with this new fewest bumble bees. Rating acquisition out of variety fullness into the websites remained an identical apart from Solon Prairie, hence diminished one or two towns and cities from inside the relative score, appearing absolutely nothing effect of testing efforts for the variety fullness.
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). დაწვრილებით „We grabbed a total of 943 bumble bees owned by eight variety“
