• Notes:
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M.
