Abstract
We studied the phonotactic response of Alytes cisternasii females at different reproductive stages (before and after oviposition) toward two male call characteristics (call rate and frequency) differing in variability, as well as in the strength of female preference. We measured female phonotactic response over several repetitions by means of the frequency of selection of the population-preferred alternative, consistency of choice, frequency of reciprocal calling activity, frequency of null trials, and average approach time. Our results showed that female mating preferences in A. cisternasii are highly influenced by the variability of male call characteristics, while only female motivation is related to reproductive stage.
