Isolation mechanisms in Osmia

Females of the group Osmia use acoustic signals as well as the male odor bouquet and their own relatedness to the male as criteria in choosing a suitable male to mate with. All of these criteria might also play a role in species isolation. To investigate this, we choose Osmia cornuta bees and Osmia rufa bees from Germany as two closely related species in which these criteria might play a role as isolation mechanisms. For further investigations we choose Osmia rufa rufa and Osmia rufa cornigera from Spain to be compared with Osmia rufa rufa from Germany. This way we are able to analyze if there are any differences in allopatric species (Germany) and sympatric species (Spain) according to their isolation mechanisms. We will compare the sound made by the male bees using a laserdopplervibrometer, the genetics using microsatellites and the odor using GC, GC-MS and GC-EAD.
