... includes using celestial cues in combination with an internal clock, geomagnetic cues such as magnetic intensity or perhaps even olfactory cues. Presently, there is not enough evidence to rule out any of these, and years of studying birds in a laboratory setting have yielded partly contradictory results...

... of other long-distance ocean navigators. Hatchling loggerhead turtles ( Caretta caretta ) detect both magnetic inclination angle ( Lohmann and Lohmann, 1994 ) and field intensity( Lohmann and Lohmann, 1996b ). Furthermore, when hatchlings were subjected to magnetic fields that exist at three widely...

...Kenneth J. Lohmann; Catherine M. F. Lohmann; Nathan F. Putman SUMMARY Diverse animals detect the Earth's magnetic field and use it as a cue in orientation and navigation. Most research on magnetoreception has focused on the directional or `compass' information that can be extracted from the Earth's...

...John H. Wang; Shaun D. Cain; Kenneth J. Lohmann SUMMARY Diverse animals use the Earth's magnetic field as an orientation cue, but little is known about the sensory, processing and motor elements of the neural circuitry underlying magnetic orientation behavior. The marine mollusc Tritonia diomedea...

... caretta L., captured turtles were tethered in a water-filled arena located outdoors. Turtles tested under these conditions established and maintained headings in specific directions in the absence of wave cues, familiar landmarks and chemical gradients. Distorting the magnetic field around the anterior...

...John H. Wang; Shaun D. Cain; Kenneth J. Lohmann SUMMARY Behavioral experiments have demonstrated that the marine mollusc Tritonia diomedea can use the Earth's magnetic field as an orientation cue. Little is known, however, about the neural mechanisms that underlie magnetic orientation behavior...

...Robert C. Beason; William J. Brennan The magnetic characteristics of the heads from 28 bobolinks [Icteridae: Dolichonyx oryzivorus (L.)] were analysed using remanence magnetometers. The natural remanent magnetization of 12 freshly preserved heads averaged 3.20xl0 −7 electromagnetic units (e.m.u...

...KENNETH J. LOHMANN The magnetic characteristics of 15 western Atlantic spiny lobsters ( Panulirus argus ) were analysed with a superconducting cryogenic magnetometer. Each specimen possessed a significant natural remanent magnetization (NRM) and isothermal remanent magnetization (IRM), indicating...
