Sequence Capture Versus Restriction Site Associated DNA Sequencing for Phylogeography [PDF]

open access: yesSystematic Biology 65: 910-924 (2016), 2013
Genomic datasets generated with massively parallel sequencing methods have the potential to propel systematics in new and exciting directions, but selecting appropriate markers and methods is not straightforward. We applied two approaches with particular promise for systematics, restriction site associated DNA sequencing (RAD-Seq) and sequence capture (
