Bioacoustics, seismic  communication, and behavioral ecology of wolf spiders
Advisor: Dr. George Uetz

Research Information

Research Interests

My research focuses on the vibratory communication signals produced by male Gladicosa gulosa (Araneae: Lycosidae) wolf spiders during courtship. I use Laser Doppler Vibrometry and live acoustic recording via sensitive microphones in an anechoic chamber to document the courtship signal structure in this species. My goals are to quantitatively analyze the pattern and contour of this signal, measure and evaluate the anatomical structures relevant to sound production in this species, test the significance of ecologically-relevant variables in wolf spider communication, and model the evolution of sound production in animals from a vibratory precursor.
