Despite possible limitations, magnetoreception may be maintained by natural selection because the geomagnetic field is sometimes...

Taken together, these findings provide additional evidence for magnetoreception in spiny lobsters, raise the possibility...

... the involvement of radical-pair reactions in the primary magnetoreception process. Birds trained and tested under 638 nm red light showed a weak tendency to orient ∼45 deg clockwise of the trained magnetic direction. Under low-irradiance 460 nm blue light, they tended to orient along the trained magnetic compass...

Among the candidate magnetoreceptive mechanisms are the cryptochromes, flavoproteins located in the retina that are supposed to perceive the magnetic...

... chickens, suggesting that the physical basis for magnetoreception is present. In behavioural tests, however, young chicks 5 to 7 days old failed to show a preference of the training direction; on days 8, 9 and 12, they could be successfully trained to search along a specific magnetic axis. Trained...

... magnetoreception True navigation describes behaviour in which an animal is able to return to a known goal from an unfamiliar area without access to cues emanating from it or information from the displacement to the unfamiliar site ( Able, 2001 ; Griffin, 1952 ; Keeton, 1974 ). The homing pigeon is a long...
