Sound Beneath the Waves

Abstract

Crayfish are wonderful organisms for science. As a keystone species, the crayfish plays an important role in the ecosystem of freshwater bodies and has an amazing set of behaviors primarily driven by their sense of smell. The downside of these organisms is that they are aquatic and nocturnal. Given my current research location, the Upper Midwest of the United States, this often means late-night dives to the bottom of fairly cold lakes. My usual location of these dives is Douglas Lake at the University of Michigan Biological Station.
