mitochondrial genome differences between the stingless bees melipona rufiventris and melipona mondury (apidae: meliponini).within the meliponini, a widely distributed group of stingless bees, melipona rufiventris has been considered as a single, cohesive species. recently, analysis of morphological characters led to the splitting of this species into two species, m. mondury and m. rufiventris. the former occurs in the atlantic rain forest ranging from santa catarina to bahia states, while the latter is found in other parts of brazil. we used pcr + rflp to identify genetic marker patterns of the mtdna between these s ...200717278085
genetic differentiation in the stingless bee, scaptotrigona xanthotricha moure, 1950 (apidae, meliponini): a species with wide geographic distribution in the atlantic rainforest.stingless bees are important pollinators that are severely threatened by anthropic interference, resulting in a strong population decline. scaptotrigona xanthotricha has a wide distribution in the atlantic rainforest, ranging from the northeastern state of bahia to santa catarina in southern brazil. to understand the genetic structure of s. xanthotricha, 12 species-specific microsatellite loci were analyzed in 42 colonies sampled throughout the species range. the results indicated 5 distinct clu ...201724829365
