... ( Collette and Collette, 2011 ; Gould, 2011 , 2014 ). For instance, do turtles inherit a magnetic map that permits them to assess their position anywhere along the North Atlantic subtropical gyre, or do magnetic orientation responses exist in only a few specific geographic areas? Moreover, how do magnetic...

... migratory species, the European robin and the garden warbler, CRYs are expressed in the retina of the eye and their magnetic orientation performances under low-intensity monochromatic light are wavelength-dependent, i.e. birds are well oriented only when exposed to short wavelengths (<565 nm) ( Rappl et...

... site in the upwelling zone of Peru along highly predictable,straight-line routes. We used satellite telemetry to follow free-flying albatrosses after manipulating magnetic orientation cues by attaching magnets to strategic places on the birds' heads. All experimental, sham-manipulated and control birds...

.... Consistent with a photoreceptor-based magnetic compass mechanism, magnetic orientation responses in salamanders, flies and birds have been shown to be affected by the wavelength of light. In birds and flies, it is unclear whether the effects of light on magnetic orientation are due to a direct effect...

... tested during January-March exhibited weak bimodal magnetic orientation along the axis of the holding tank. However, during the spring migratory period (April until early May), the bimodal response shifted to coincide with the direction of the pond from which the newts had been collected. Much stronger...
