Table 1 in Modification of vertebral regions explains heart position in arboreal colubrids (Serpentes: Colubridae)

Table 1. ANCOVA of intracolumnar profile shape predicted by ecological groups (ecology) with heart position as a covariate (f1 = intracolumnar profile ~ heart position * ecology). Where intracolumnar profile is the x,y coordinates of vertebra position and cumulative relative size as seen in Figure 3. Degrees of freedom (d.f.), sum of squares (SS), mean square (MS), coefficient of determination (R 2), test statistic (F), effect size (Z), and P -value based upon the F statistic (Pr) for each factor are provided d.f.SSMSR 2FZPrHeart position11825.8581825.8580.0169720.670 8180.264 3060.412Ecology114 155.9214 155.920.131 5835.20 0871.80 9860.024Heart position: ecology115 388.2815 388.280.143 0385.653 6381.779 3060.032Residuals2876 211.412721.8360.708 407Total31107 581.5 (f1 = intracolumnar profile ~ heart position * ecology).
