Appendix S2 Procedures of DNA extraction, amplification, sequencing and alignment. Genomic DNA was extracted from tissue samples using a phenol-chloroform protocol (Bruford et al., 1992) or a DNeasy tissue kit (Qiagen, Valencia, CA, USA), following the manufacturer’s protocol. Primers for amplification were Fib7U and Fib7L for Fib7 (Prychitko & Moore, 1997), L14841 (Kocher et al., 1989) and H16065 (Cracraft & Helm-Bychowski, 1993) for cyt b, L5215 (Hackett, 1996), LMet and H6313 (Sorenson et al.,1999) for ND2, and L10755 and H11151 for ND3 (Chesser, 1999). Internal sequencing primers for Fib7 were 413U (Chesser, 2004) and 453LSclerurus (5'GTACTTTACAACTGAGCTCCA-3'), developed for this study; for cyt b were P5L and H658 (Irestedt et al., 2002), and for ND2 were L5758 and H5766 (Sorenson et al., 1999). Amplifications were performed in 25 µL reactions as described in Brumfield et al. (2007) or in 10 µL reactions containing 0.8 mM dNTP, 1 mM of each primer, 0.5 U Taq polymerase (Pharmacia), buffer 1X (Pharmacia), and 1 m (~10 ng) of template DNA. Locus-specific annealing temperatures were 54 °C, 54 °C, 59 °C and 54 °C for Fib7, cyt b, ND2 and ND3, respectively. The thermocycling conditions were as follows: an initial denaturation at 95 °C for 2–5 min, followed by 35–40 cycles of denaturation at 95 °C for 1–2 min, annealing at 54–59 °C for 30 s, extension at 72 °C for 40 s, and a final extension step at 72 °C for 5 min. Amplicons were visualized by electrophoresis in 1% agarose gel and purified using 20% polyethylene glycol. Both strands of purified amplicons were cycle-sequenced using Big Dye Terminator kit 3.1 (Applied Biosystems, Foster City, CA, USA), purified with Sephadex (G-50 fine), and sequenced on either an ABI 377 Automated Sequencer or an ABI 3100 Genetic Analyzer (Applied Biosystems). Sequences were inspected, edited, and aligned using CodonCode Aligner (CodonCode Corporation) and the algorithm Clustal X (Thompson et al., 1997).
