32. Detection of coastal mud odors by loggerhead sea turtles: a possible mechanism for sensing nearby land

Abstract

For sea turtles, an ability to detect land masses from a considerable distance away, and to distinguish coastal areas from the open sea, might be adaptive. The loggerhead turtle, Caretta caretta, can detect airborne odorants associated with food. To investigate whether sea turtles can also detect odors associated with land, we studied the responses of juvenile loggerheads to odors from coastal mud. Turtles were tested in a water-filled arena in which odorants could be introduced to the air above the water surface. Turtles exposed to air that had passed over a cup containing mud spent more time with their noses out of the water than did control turtles exposed to air that had passed over a cup containing distilled water. The results demonstrate for the first time that loggerheads can detect airborne odorants associated with land, an ability that might play a role in foraging, navigation, or both., Introduction Sea turtles migrate immense distances, sometimes crossing entire ocean basins before returning to their natal region to reproduce (Carr et al. 1978; Bolten 2003; Musick and Limpus 1997).

45. The neurobiology of magnetoreception in vertebrate animals

Author

Lohmann, Kenneth J. and Johnsen, Sonke

Subjects
Biomagnetism -- Physiological aspects, Health, Psychology and mental health
Abstract

Diverse vertebrate animals can sense the earth's magnetic field, but little is known about the physiological mechanisms that underlie this sensory ability. Three major hypotheses of magnetic-field detection have been proposed. Electrosensitive marine fish might sense the geomagnetic field through electromagnetic induction, although definitive evidence that such fish actually do so has not yet been obtained. Studies with other vertebrates have provided evidence consistent with two different mechanisms: biogenic magnetite and chemical reactions that are modulated by magnetic fields. Despite recent progress, however, primary magnetoreceptors have not yet been identified unambiguously in any animal.

46. Hatchling sea turtles use surface waves to establish a magnetic compass direction

Author

Goff, Matthew, Salmon, Michael, and Lohmann, Kenneth J.

Subjects
Loggerhead turtle -- Behavior, Sea turtles -- Behavior, Animal migration -- Research, Zoology and wildlife conservation
Abstract

The orientation behavior of loggerhead hatchling sea turtles that had been exposed to waves for either 15 or 30 minutes was explored to determine whether the turtles use surface waves to establish a magnetic compass direction. Results revealed that hatchlings can transfer a heading induced by waves to a magnetic compass. These turtles relied on multiple cues and the ability to transfer information between various cues for their migratory orientation.
