Navigation and seasonal migratory orientation in juvenile sea turtles

Results demonstrate for the first time that both homing and migratory orientation can be elicited in juvenile turtles under laboratory conditions in which orientation cues can be readily manipulated and provide evidence that juvenile loggerheads can assess their position relative to a goal using local cues available at the test site and are therefore capable of map-based navigation.

New Perspectives on the Pelagic Stage of Sea Turtle Development

It is now obvious that when young cultured sea turtles are released in so-called head-starting projects, the release sites ought to be chosen with the greatest care, and it is also necessary to avoid release localities where the convergence habitat may carry heavy loads of material.

Navigation in context: grand theories and basic mechanisms

This work aims to use modern recording technology to unravel the detailed spatial and temporal structures of migratory routes and foraging trajectories, study the animal's sensory and computational abilities by combining behavioural and neurophysiological approaches, and work bottom-up, as evolution did, by trying to integrate the individual navigational methods.
