Abstract
"The evolution of mate preferences can be critical for the evolution of reproductive isolation and speciation. Heterospecific interference
may carry substantial fitness costs and result in preferences where females are most responsive to the mean conspecific
trait with low response to traits that differ from this value. However, when male traits are unbounded by heterospecifics, there
may not be selection against females that respond to extreme trait values in the unbounded direction. To test how heterospecifics
affected the shape of female response functions, I presented female Oecanthus tree crickets with synthetic calls representing a
range of male calls, then measured female phonotaxis to construct response functions. The species with the fastest pulse rates in
the community consistently responded to pulse rates faster than those produced by their males, whereas in the intermediate and
slowest pulse rate species there was no significant difference between the male trait and the female response. This work suggests
that species with the most extreme signal in the community respond to a greater range of signals, potentially resulting in a higher
probability of hybridization during secondary contact, and revealing interactions between mate recognition and other aspects of
sexual selection."
