Biology Seminar: "Neuroethology of prey capture in dragonflies: vision, decision, precision"Contributed by Nancy Pierce on 03/27/12
Thursday, April 5 (PDF) Refreshments served at 3:45, 1st floor CNS foyer. Bring your mug. Reduce, Reuse, Recycle. Individuals with disabilities requiring accommodations should contact Nancy Pierce at npierce@ithaca.edu or (607) 274-3161. We ask that requests for accommodations be made as soon as possible. ~~~~~~~~~~ In my research I investigate the neuroethology of insect hunting and capture in dragonflies. I want to know what aspects of prey detection are fixed or flexible and how environmental conditions (light levels, temperature, prey abundance) influence prey-capture behavior or the detection of prey-like stimuli. I use high speed video to record the foraging behavior of free flying dragonflies and neurobiological techniques to investigate the sensory biology of the insects. Students have worked with me on the sensory biology of dragonflies. They have analyzed films of foraging dragonflies and performed experiments on prey size preference in aquatic larval dragonflies in the lab. |
