Juliane Lukas
PhD student
I am a pre-doctoral researcher studying the mechanisms and functions underlying group-living and cooperative behaviors in animals with an emphasis on collective predator evasion. I have strong interests in how consistent individual differences ('personality') drive collective behavior and influence social dynamics in naturally gregarious animals. I implement observational and experimental approaches in the lab and field, combining concepts and methods from ethology, ecology and evolutionary biology with statistical and mathematical models.

collective predator evasion:

Predator avoidance in extremophile fishes - mechanisms and functions underlying repeated fright waves


Shoaling behavior and sociability

Real-time behavior tracking and social cue manipulations via a biomimetic robot (Robofish)


Consequences of Behavioral types

Using thermally altered aquatic systems to study biological invasion syndromes along environmental gradients
