    Abstract

    The functional response is the relationship between an individual predator's consumption rate (defined as the number of prey eaten), and the density of its prey. Basic functional response theory was elucidated in the 1950s in a series of laboratory simulations, in which a predator (a blindfolded assistant) hunted for prey (discs of sandpaper) on a desktop. Here we explain how these classic simulations Can be adapted as enjoyable and informative teaching exercises for students from a variety of backgrounds. The basic simulation is useful for providing 'hands-on' insights into the dynamics of prey capture at varying prey densities, while more sophisticated examples require students to demonstrate their understanding by manipulating the simulation to produce particular functional response curves, or to model their data using some of the statistical approaches available.
