Table 1. Coefficients (mean, standard deviation, and 2.5th and 97.5th percentiles) of the variables included in the regression models of call frequency as a function of traffic noise, expressed as L10 18 hr dB(A) SPL, and temperature expressed as degrees Centigrade. Coefficients are shown for the models of the dominant frequency of the call of Litoria ewingii and the lower frequency of the call of Crinia signifera.
