DESCRIPTION:Differences in female preference for certain characteristics of
  males can be a driving force for population divergence and speciation. We
  show that in the red mason bee\, Osmia bicornis\, females choose suitable
  males based on\, among other criteria\, their vibrations.\nAs mason bees 
 are very efficient pollinators and therefore being used increasingly in ag
 riculture it is important to know how different populations interact and h
 ow separated they might already be. We investigated whether there is selec
 tive mate choice between O. bicornis individuals originating from differen
 t regions in Europe and whether the male&rsquo\;s vibrations play a role i
 n this. In order to investigate whether females do indeed use the males&rs
 quo\; vibrational signals for selective mate choice we experimentally chan
 ged the vibrations in a live male during mating. To achieve this we design
 ed a new and innovative set-up using an inductor and small magnets.\nClima
 te change and the resulting changes in air temperature are known to have a
  major influence on most animals\, especially poikilothermic insects\, bec
 ause they depend on the high enough temperatures to function. Mason bees a
 re some of the first bees to emerge in spring and are therefore subject to
  high temperature fluctuations. We investigated the impact of different te
 mperatures on their complex mating behavior.\nOur results give exciting ne
 w insights into the scope of vibrational communication in bees\, a group p
 reviously thought to mostly rely on chemical signals for communication\, a
 nd the impact our ever-raising temperatures could have on these important 
 pollinators.
