Mitogenome Assembly
We trimmed adapters from Illumina raw reads with BBDuk (k = 23, tpe option), before using them as input to NOVOPlasty 2.7.2 (Dierckxsens, Mardulyn, & Smits, 2017). The Puffinus lherminieri mitogenome (MH206163.1) was used as seed using the following parameters: Genome Range (16000-24000), Insert size (422), Insert range (1.74) and Insert range strict (1.3). The annotation was performed using the MITOS WebServer (Bernt et al., 2013).
