For all but one extraction, we performed an initial long range
PCR amplification targeting a mitochondrial fragment of
6000 bp using the KOD Xtreme™ Hot Start DNA Polymerase⁄ kit. The 25 ll long-range PCR reactions incorporated 12.5 ll of 2 Xtreme Buffer, 5 ll of dNTPs (2 mM each), 0.5 ll each of the heavy and light strand primers (10 lM), 0.5 units of KOD Xtreme™ Hot
