F. 3. Respiratory exchange ratio (mL CO - mL O —1) of P. siculus (n IG 2 2 = 19) at 14 d prior to tail autotomy (preautotomy), 2 d after autotomy (postautotomy), and 64 d after autotomy (follow-up). Horizontal lines within each box indicate the median values, and the box boundaries indicate the lower quartile (lower boundary) and upper quartile (upper boundary). Whiskers indicate minimum and maximum values within a quartile ± 1.5 times the interquartile range; individual points are outliers that occurred outside this range. Different letters above each plot represent significant differences among means at those time points.
