TABLE 8. Regression and proportion parameters Heteroclinus longicauda. P following y-intercept indicated the probability of y-intercept is significantly different from 0. Size trend indicates whether proportion decreases or increases with size (Tau and p for Tau), size range is mm SL. Shaded probabilities indicate significant differences at or less than 0.05.
