Polarized light orientation in honey bees: Is time a component in sampling?
Tóm tắt
Bees on a horizontal comb can orient their dances by a field of polarized light in the zenith even when the degree of polarization of this light field is modulated from 0 to 100%, at frequencies between 0.05 and 25 Hz, with the direction of polarization and the intensity kept constant. The result suggests that bees use a process of polarized light evaluation which probes simultaneously with three or more differently oriented analyser channels. It would follow that, in this experimental situation, time is not a component of sampling.
