Data for 27 °C and 28 °C calculated from Chou (1992). Closed circle = note with 11 pulses (Y=+, r = , n = 3, p=); open circle = note with nine pulses (Y=, r=, n = 4, p=). p = ), though the slopes did not differ between the two lines (ANCOVA: p> ). Pulse repetition rate also correlates to the temperature, and the number of pulse per unit time is predicted to increase under higher temperature conditions (fig. 6). The relationships of repetition rate (Y) to temperature (X) in the notes with nine and 11 pulses are expressed as Y=— (r=, p = ) and Y=+ (r = , p = ), respectively. Unlike in the note duration, neither the slope nor position differed in the two regression lines (ANCOVA:.
