Improvements to resampling measures of group support
Pablo A. Goloboff,James S. Farris,Mari Källersjö,Bengt Oxelman,Martín J. Ramírez,Claudia A. Szumik +5 more
TL;DR: Several aspects of current resampling methods to assess group support are reviewed in this article, where problems with interpreting absolute group frequencies as a measure of the support are discussed; group support does not necessarily vary with the frequency itself, since in some cases groups with positive support may have much lower frequencies than groups with no support at all.
Journal ArticleDOI
Reliability of Bayesian posterior probabilities and bootstrap frequencies in phylogenetics.
TL;DR: It is shown that Bayesian posterior probabilities are significantly higher than corresponding nonparametric bootstrap frequencies for true clades, but also that erroneous conclusions will be made more often.
Journal ArticleDOI
Chloroplastrps16 intron phylogeny of the tribeSileneae (Caryophyllaceae)
TL;DR: The joint usage ofrps16 intron and ITS sequences provides a powerful tool for resolving many of the difficult taxonomic issues in the tribeSileneae.
Journal ArticleDOI
Phylogenies without roots? A plea for the use of vouchers in molecular phylogenetic studies.
Fredrik Pleijel,Ulf Jondelius,Erika Norlinder,Arne Nygren,Bengt Oxelman,Christoffer Schander,Per Sundberg,Mikael Thollesson +7 more
TL;DR: A plea for the use of vouchers in molecular phylogenetic studies is made and it is suggested that vouchers should be placed in the phylogenetic tree for the sake of clarity.
Journal ArticleDOI
Piecing together the "new" Plantaginaceae.
TL;DR: In a phylogenetic study of 47 members of Plantaginaceae and seven outgroups based on 3561 aligned characters from four DNA regions, the relationships within this clade were analyzed and the results from parsimony and Bayesian analyses support the removal of the Lindernieae from Gratioleae to a position outsideplantaginaceae.
