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
