Violin-plots comparing tree support values for different sized alignments with means denoted by a diamond. We compare the ND2 gene alone (1,039 bp), Fragment 1 (9,636 bp), and the entire mitochondrial genome excluding the D-loop (16,654 bp) for (A) ultrafast bootstraps (UFboots) and (B) approximate likelihood-ratio tests (ALRT) implemented in IQ-TREE. Violins have equal widths for easier visualization of the distributions. Groups with significantly different means by Tukey’s HSD test are labeled with different letters above the plots
