Abstract: | Summary Genetic structure ofCamponotus herculeanus populations was studied using both traditional allozyme markers and recently discovered DNA microsatellites. Relatedness among worker nest mates was high in one study population (0.70), but lower in another (0.48). The estimates lower than 0.75, together with the multilocus genotype patterns, indicate either multiple mating by queens, or multiple queens reproducing in the colonies. These two could not be distinguished with the current data, although multiple matings seem a more probable explanation for the relatedness estimates bearing social biology of the species in mind. Inbreeding coefficients suggested random mating in both populations. Both allozyme and DNA microsatellite markers gave the same result concerning genetic parameters estimated, but the higher variability of the microsatellites resulted in more precise estimates of both parameters. |
