In an integrated set of studies, the Reppert laboratory is using anatomical, cellular, molecular, electrophysiological, genetic and behavioral approaches to more fully understand the biological basis of monarch butterfly (Danaus plexippus) migration, with a focus on the butterfly's navigational abilities and its distinctive circadian clock.
This website is intended as a resource and a gateway for monarch lovers of all stripes (and spots). Take a look around to learn about monarch biology and to discover the many open questions our lab continues to explore.
