Upierzenie kuropatwy czerwonej
Upierzenie kuropatwy czerwonej – Researchers from the University of Bristol have discovered that plants attract the attention of their pollinators using electrical signals. While the flowers usually have a negative charge and send a weak electrical impulses, the bees send out a positive charge (with a force of 200 V), which obtain during the flight. Charges are very weak, so there will be no spark. However, it formed a small electric voltage that indicates the locus of bee sweet source.
