Table 3 Population genetic statistics for bumble bees (Bombus spp.) in the greater Saint Louis region. Allelic richness (AR), calculated as mean allele number across loci, is calculated per species for each site and combining all sites (i.e., global AR). FST describes population genetic differentiation. FIS is the inbreeding coefficient. All populations with < 25 successfully genotyped individuals following quality control measures were removed from population genetic analyses. SE standard error, 95% CI 95% confidence interval, CC Calvary Cemetery, CW Castlewood State Park, ED EarthDance Farms, SNR Shaw Nature Reserve.

From: Bumble bees exhibit body size clines across an urban gradient despite low genetic differentiation
