Assessing the impact of phylogenetic incongruence on taxonomy, floral evolution, biogeographical history, and phylogenetic diversity

• Phylogenetic incongruence between “gene trees” and “species trees” has been widely acknowledged in phylogenetic research. Conflicts may emerge from several processes including paralogy, hybridization, and incomplete lineage sorting. Although phylogenetic incongruence appears common, its impact on... Full description

description: • Phylogenetic incongruence between “gene trees” and “species trees” has been widely acknowledged in phylogenetic research. Conflicts may emerge from several processes including paralogy, hybridization, and incomplete lineage sorting. Although phylogenetic incongruence appears common, its impact on many phylogeny‐based analyses remains poorly understood. • We examined the occurrence of phylogenetic conflict between nuclear (ribosome ITS) and plastid (, ‐, ‐, and intron) loci in the ancient angiosperm family Chloranthaceae. Then we investigated how phylogenetic conflict bears on taxonomic classification within the family as well as on inferences on biogeographical history, floral evolution, and measures of phylogenetic diversity (PD). • We found evidence for significant phylogenetic incongruence between plastid and nuclear data in the genus . Within , our results did not support previous subgeneric classification of the genus. Division of sections within subgenus was supported by the ITS data but not by the plastid data set. As a consequence, we showed that inferring the evolution of key floral characters and geographical history within depends on the phylogenetic data used. Both data sets yielded similar PD measures across genera, but we found contrasting PD measures in , even after correcting for rate heterogeneity. • Our study demonstrated that phylogenetic conflict not only affects the inference of organismal relationships but also impacts our understanding of biogeographical history, morphological evolution, and phylogenetic diversity.
