“The results of our experiments suggest the remarkable sensitivity … of the Antarctic amphipod … Even 2 nT RF regardless of frequency was able to disrupt orientation.” (1-10 MHz)
“Our findings that the direction of vertical migrations could be reversed by an imposed magnetic field and that wild-type populations of worms from opposite hemispheres displayed opposite vertical migration preference strongly suggests that C. elegans relies on the geomagnetic field rather than gravity.” (open access).
By a group at Germany’s University of Oldenburg. “[U]sing a double-blinded protocol we have documented a clear and reproducible effect on a biological system of anthropogenic EM fields much weaker than the current ICNIRP guidelines.” With an accompanying comment by Joe Kirschvink of CalTech: The authors “demonstrate convincingly that migrating European robins stop...
“[W]e speculate that the widely observed weak-field [~50 nT] biomagnetic responses typified … stem from early evolutionary recognition of the diurnal change in the [geomagnetic field] as a precise zeitgeber; indeed one that outperforms the sun itself, in that it happens independently of cloudy skies.”
“A Sense of Mystery: Researchers from various disciplines are homing in on the mechanics of magnetoreception, an enigmatic sense that some animals use to navigate the globe.” The Scientist, August 1, 2013.
“Most researchers in the field agree that the compass sense is likely seated in cryptochromes within the eye, and many are convinced that there is another sense, most likely a signpost sense, passed through the trigeminal nerve and probably based on some sort of iron-containing, magnetism-sensing cells in beaks or snouts. Then there is [David] Dickman and [Le-Qing] Wu’s idea: that both of these abilities may rely on receptors in the inner ear.”
