Uncovering the evolutionary history of the dung moss Tetraplodon fuegianus: A comparison of Sanger, organellar genomic, and RADseq datasets.

Populations of the South American sub-Antarctic endemic Tetraplodon fuegianus compose a monophyletic lineage that diverged from high-latitude Northern Hemisphere populations of T. mnioides during the late Miocene to Pliocene, (mean 8.6 Ma, 95% HPD 3.0–10.1 Ma), and diversified in the late Miocene to late Pleistocene, (mean 5.2 Ma, 95% HPD 1.4 - 7.0 Ma). We compare levels of intraspecific variation in T. fuegianus across three types of datasets (four standard phylogenetic loci, complete organellar genomes and nuclear ribosomal repeat, and RADseq data) and discuss the utility of these distinct sources for reconstructing the evolutionary history of a widespread and disjunct complex.
