| Abstract: | In this article we present generalized theoretical models ofmate attraction in acoustic communication.The models use simpledecision rules for females and show theoretical differencesbetween the rules in relative attraction of females to soundsources (calling males). The important variables of the modelsare the relative powers of the sources, the distance betweenthe sources and the number of competing signalers.Relative attractionamong sources is a function of their relative power output withmore powerful signals attracting more females. Using differentassumptions about the spacing of sources with respect to femalesensitivity, data from phonotaxis studies can be explained wellby either random pick or active choice models. Bioacousticiansmust reexamine their use of, and conclusions based on, the two-choiceplayback paradigm in studying female mate choice. |
