Is the São Francisco River a historical barrier to gene flow for populations of Melipona mandacaia Smith, 1863 (Hymenoptera: Apidae)?

Large rivers are usually associated with vicariance and diversification of terrestrial species, but little is known about these effects in overlooked areas from South America, like São Francisco River (SFR). In this study we tested this hypothesis by analyzing populations of Melipona mandacaia , an...

Description
Summary:Large rivers are usually associated with vicariance and diversification of terrestrial species, but little is known about these effects in overlooked areas from South America, like São Francisco River (SFR). In this study we tested this hypothesis by analyzing populations of Melipona mandacaia , an endemic stingless bee from Caatinga whose distribution is associated to SFR. The influence of the river width as a natural barrier to the gene flow among populations of M. mandacaia from both margins of SFR was inferred from genetic and morphometric data. Eleven microsatellite loci were amplified and 813 anterior right wings were used for geometric morphometrics. Most of the genetic variation (96.7%) in AMOVA was found within populations with evidence of low structuring (Fst = 0.032, p
