Scoring efficiency of the microsatellite loci for each Bombus spp.

With n = the number of workers and between brackets the number of workers used in all further analysis, NA = the number of specimens that were not amplifiable, FS = the number of full sibs, and PUA = the proportion of unsuccessfully amplified individuals per locus (in %). Microsatellite loci not used for further analysis are underlined with a full line, loci that were not used in only one population of a certain species are underlined with a dotted line, L = the number of loci used in further analysis.* = workers of B. pascuorum from two additional time points: 1942–1960 and 1975–1995.Scoring efficiency of the microsatellite loci for each Bombus spp.
