“…Nonetheless, no inbreeding depression was detected here. These results are similar to those of B. terrestris in Tasmania (Schmid-Hempel et al 2007). The latter study demonstrated that despite a drastic genetic bottleneck, B. terrestris could successfully invade and colonize Tasmania.…”

Microsatellite analysis in museum samples reveals inbreeding before the regression of Bombus veteranus

-The worldwide decline of pollinators is an emerging threat and is a matter both for ecological and economic concerns. Population genetics can be used to correlate bumblebee decline with genetic parameters. In order to do so, historical data are needed. We used eight microsatellite loci to genotype pinned museum specimens of the declining bumblebee Bombus veteranus. Bumblebee samples were collected spanning a period of three decades . We detected low genetic diversity and inbreeding in the samples collected during the respective time periods. Inbreeding was also confirmed by the occurrence of sterile diploid males. Based on the data obtained, we speculate that low genetic diversity and inbreeding did not directly result in the collapse of B. veteranus in Belgium. However, inbreeding might still play an indirect role in the decline of bumblebee populations because of the appearance of diploid males and because a low H E might reduce the capacity to react to the drivers of bumblebee decline. microsatellites / ancient DNA / museum collections / genetic diversity / bumblebee decline

“…This trait, when accompanied with highly invasive abilities even from very few founders (Allen et al, 2007;Schmid-Hempel et al, 2007), means that there is a high potential for rapid spread (Hergstrom et al, 2005 and references therein but see MacFarlane and Gurr (1995) that in New Zealand large numbers of queens are required to successfully colonize an area). B. terrestris can spread rapidly; 90 km/year in New Zealand (Hopkins, 1914), 25 km/year (Hingston et al, 2002) in Tasmania.…”

“…In this vortex, populations are reduced, e.g., due to habitat fragmentation, which leads to decreased allelic diversity, increased inbreeding, and the production of diploid males so that the extinction risk of the population increases. Nevertheless the haplodiploid system could select negatively against the deleterious alleles and thereby balance the costs of inbreeding and low genetic diversity (Schmid-Hempel et al 2007). Some studies have tried to quantify the presence of diploid males in wild populations.…”

Discrimination of haploid and diploid males of Bombus terrestris (Hymenoptera; Apidae) based on wing shape

et al. 2015

View full text Add to dashboard Cite

-Presence of diploid males in wild bees reflects inbreeding and provides information about the health status of a colony or population. Detection of diploid males, and discrimination from haploid males and workers, has, however, been limited to molecular diagnostics. Here we present a novel method based on differences in wing shape, e.g., venation patterns in wings. The method is easy to apply and results, for Bombus terrestris , in very high discrimination success. Possible applications of the method are discussed.Bombus / decline / diploid males / wing shape / geometric morphometrics
