Mitochondrial DNA of Euglossa iopoecila (Apidae, Euglossini) reveals two distinct lineages for this orchid bee species endemic to the Atlantic Forest

This study analysed the population genetic structure of Euglossa iopoecila, an orchid bee species endemic to the Atlantic Forest which shows a variation in the colour of its metallic integument across its distribution. Our analyses were based on microsatellite and mitochondrial markers. From ten mic...

Description
Summary:This study analysed the population genetic structure of Euglossa iopoecila, an orchid bee species endemic to the Atlantic Forest which shows a variation in the colour of its metallic integument across its distribution. Our analyses were based on microsatellite and mitochondrial markers. From ten microsatellite loci surveyed, six are described herein for the first time. Mitochondrial markers were obtained by sequencing 651 bp of Cytb gene. Bees were collected from six Atlantic Forest remnants distributed along the Serra do Mar Biodiversity Corridor, which is one of the largest remnants of dense forest within the Atlantic Forest of southern and south-eastern Brazil. The microsatellite markers showed lower levels of genetic structure than those found for mitochondrial markers. Our findings based on mitochondrial markers indicate the existence of at least two different evolutionarily significant units of E. iopoecila populations along the Serra do Mar Biodiversity Corridor.
