SUMMARY:Daniel Robert (University of Bristol\, UK): The bee\, the flower an
 d the Coulomb force
DESCRIPTION:Daniel Robert: Exchanging nutrition for pollination services\, 
 bees and flowers interact relying on vision\, olfaction\, touch\, and humi
 dity sensing. Recently\, we have discovered that bees can also detect and 
 learn about the weak electric field that arises when they approach a flowe
 r. This electric field is generated because flying bees are usually electr
 ically positively charged whilst flowers tend to be negatively charged. A 
 third component contributes to this electric interaction\, the atmospheric
  potential gradient (APG) that is a consequence of the ionization of the a
 tmosphere and the global electric circuit. I will present our current unde
 rstanding of this triadic interaction (Bee-Flower-APG)\, but also specific
 ally discuss the role that triboelectrification may play in the sensory ec
 ology of terrestrial arthropods and plants. I will show that physical cont
 act and friction between insects and their environment can generate charge
  separation and a Coulomb force. It will be proposed that this triboelectr
 ic charging may play a role in the biology and sensory ecology of plants a
 nd insects. The enticing possibility that many arthropod species\, beyond 
 bees\, are capable of electroreception will be briefly addressed and discu
 ssed.\n\n\n\nIOSSB Seminar\n&nbsp\;
