About Dr. Ken Lohmann:
Dr. Lohmann’s academic journey began at Duke University, where he completed his undergraduate studies. He then pursued a master’s degree at the University of Florida and earned his PhD from the University of Washington. His postdoctoral training took place at the University of Illinois and the Marine Biological Laboratory in Woods Hole. Dr. Lohmann’s lab focuses on the neuroethology of marine animals, particularly the navigational mechanisms of species that migrate over long distances. His research has encompassed a variety of marine animals, including sea turtles, salmon, spiny lobsters, sea slugs, and marine iguanas.

Presentation Title: Magnetic Navigation in Sea Turtles

Abstract:
Sea turtles are renowned for their remarkable migratory journeys, which span vast and seemingly featureless oceans. A key component of their navigational prowess is their ability to detect Earth’s magnetic field. Research indicates that this magnetic sense not only provides turtles with directional cues but also equips them with a ‘magnetic map’—a biological GPS based on geographic variations in Earth’s magnetic field. This magnetic map sense is believed to guide turtles during transoceanic migrations, help them locate foraging grounds, and enable them to return to their natal areas for reproduction. Similar navigational systems are likely present in other marine animals, such as salmon, seabirds, and marine mammals.

Join us for an insightful presentation by Dr. Ken Lohmann as he delves into the fascinating world of magnetic navigation in sea turtles.
