Table 2. Comparative shape space orientations.

Comparison (PC1)	Observed angle	Range of the 95th% CI	Range of the 95th% CI
(LM+LV) vs. LT	5.89	(LM+LV): 0.97–10.87	LT: 0.96–11.84
(LT+LV) vs. LM	2.38	(LT+LV): 0.99–4.65	LM: 0.99–5.44
(LT+LM) vs. LV	9.72	(LT+LM): 0.96–8.43	LV: 0.90–18.50
LT vs. LM	8.56	LT: 0.95–12.24	LM: 0.99–5.91
LT vs. LV	15.25	LT: 0.96–12.13	LV: 0.89–19.21
LM vs. LV	9.27	LM: 0.99–5.38	LV: 0.90–18.56

Bootstrap confidence intervals for the observed angles between shape spaces were calculated by resampling the data from both groups. Orientations were not considered significantly different if the observed angle fell within either CI. None of the orientations for the axes and planes compared above were significantly different.
