Coverage (orange curve) and GC content (black curve; 200 bp sliding window, 10 bp step width) through the mitogenome of Hemicentrotus pulcherrimus (GenBank accession no. KC898202) illustrating moderate (R2 = 0.335), but highly significant correlation (t-test, p < 10− 100) between the two graphs. Note extreme drop of coverage towards the end of the CR (highlighted in grey), which coincides with a slight decrease in GC-content, but shows a much stronger negative excursion than other GC-poor areas in the mitogenome of this species (e.g. at nucleotide positions 4.4, 8.5, or 12.6 kb)
