Rearing monarch butterflies in captivity for later release is a popular but contentious activity
due to concerns about its potential negative effects on the wild population. In this review, I …

Since the 1960s, scientists have observed the North American monarch butterfly (Danaus
plexippus) continuing reproductive activities past the fall migration and into the winter …

Neural processing of a desired moving direction requires the continuous comparison
between the current heading and the goal direction. While the neural basis underlying the …

Summary Eastern North American migratory monarch butterflies exhibit migratory behavioral
states in fall and spring characterized by sun-dependent oriented flight. However, it is …

Peak metabolic rate reflects maximal performance and may have direct fitness
consequences, whereas resting metabolic rate (RMR) represents the maintenance cost of …

In flying animals, wing morphology is typically assumed to influence flight behaviours.
Whether seasonal polymorphism in butterfly morphology is linked to adaptive flight …

We study adaptation and speciation, with a special focus on the genetic basis of wing
pattern mimicry in butterflies. Other topics of study in the lab include mate preference …
