Phylogeny, adaptive radiation, and historical biogeography in Bromeliaceae: Insights from an eight-locus plastid phylogeny
Thomas J. Givnish,Michael H. J. Barfuss,Benjamin W. van Ee,Benjamin W. van Ee,Ricarda Riina,Ricarda Riina,Katharina Schulte,Katharina Schulte,Ralf Horres,Philip A. Gonsiska,Rachel S. Jabaily,Rachel S. Jabaily,Darren M. Crayn,J. Andrew C. Smith,Klaus Winter,Gregory K. Brown,Timothy M. Evans,Bruce K. Holst,Harry E. Luther,Walter Till,Georg Zizka,Paul E. Berry,Kenneth J. Sytsma +22 more
TL;DR: A bromeliad phylogeny based on eight plastid regions is used to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of b romeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and rates of diversification.
Journal ArticleDOI
Adaptive radiation, correlated and contingent evolution, and net species diversification in Bromeliaceae
Thomas J. Givnish,Michael H. J. Barfuss,Benjamin W. van Ee,Ricarda Riina,Katharina Schulte,Katharina Schulte,Ralf Horres,Philip A. Gonsiska,Rachel S. Jabaily,Darren M. Crayn,J. Andrew C. Smith,Klaus Winter,Gregory K. Brown,Timothy M. Evans,Bruce K. Holst,Harry E. Luther,Walter Till,Georg Zizka,Paul E. Berry,Kenneth J. Sytsma +19 more
TL;DR: This study is among the first to test a priori hypotheses about the relationships among phylogeny, phenotypic evolution, geographic spread, and net species diversification, and to argue for causality to flow from functional diversity to spatial expansion to species diversity.
Journal ArticleDOI
Examination of subfamilial phylogeny in Bromeliaceae using comparative sequencing of the plastid locus ndhF.
TL;DR: Parsimony analysis of 31 sequences of the chloroplast locus ndhF was used to address questions of subfamilial phylogeny in Bromeliaceae, and data suggest that Brocchinia (Pitcairnioideae) is the sister group to the remainder of Bromeli Families.
Journal ArticleDOI
Taxonomic revision of Bromeliaceae subfam. Tillandsioideae based on a multi-locus DNA sequence phylogeny and morphology
Michael H. J. Barfuss,Walter Till,Elton M. C. Leme,Juan P. Pinzón,José M. Manzanares,Heidemarie Halbritter,Rosabelle Samuel,Gregory K. Brown +7 more
TL;DR: A taxonomic revision of Bromeliaceae subfam Tillandsioideae is presented based on a multi-locus DNA sequence phylogeny and new or re-evaluated morphology that enables the circumscription of monophyletic units using synapomorphic combinations of diagnostic morphological characters.
Journal ArticleDOI
Stigma structure and variation in Bromeliaceae—Neglected taxonomic characters
TL;DR: Stigma architecture is proving to be a rich source of data for phylogenetic reconstruction and for classification at several infrafamilial levels and is consistent with Smith’s hypothesis of phylogenetic proximity of Tillandsioidae and Pitcairnioideae.
