The influence of acoustic experience on female choosiness in contemporary T. oceanicus populations. Choosiness is indicated on the y-axis by natural log-transformed female mounting latency, with greater latency indicating greater choosiness. Error bars are omitted for ease of interpretation, but populations that differed significantly from one another in Ψ do not share one of the small letters to the right. Values of Ψ estimated from regression coefficients (see text for details) are indicated on the right, and those populations for which Ψ differed significantly from zero are indicated in bold. Squares with continuous line, Mission Beach; diamonds with continuous line, Samoa; triangles with continuous line, Hilo; crosses with continuous line, Oahu; circles with continuous line, Contemporary Kauai.
