Journal ArticleDOI
Sympatric speciation in palms on an oceanic island
Vincent Savolainen,Marie-Charlotte Anstett,Christian Lexer,Ian Hutton,James J. Clarkson,Maria Vibe Norup,Maria Vibe Norup,Martyn P. Powell,David A. Springate,Nicholas Salamin,William J. Baker +10 more
TL;DR: A large dated phylogenetic tree shows that the two species of Howea, endemic to the remote Lord Howe Island, are sister taxa and diverged from each other well after the island was formed 6.9 million years ago.
Journal ArticleDOI
Molecular phylogenetics of Caryophyllales based on nuclear 18S rDNA and plastid rbcL, atpB, and matK DNA sequences
Philippe Cuénoud,Vincent Savolainen,Lars W. Chatrou,Martyn P. Powell,Renée J. Grayer,Mark W. Chase +5 more
TL;DR: Two additional lineages are potentially appropriate to be elevated to the family level in the future: the genera Lophiocarpus and Corbichonia form a well-supported clade on the basis of molecular and chemical evidence, and Limeum appears to be separated from other Molluginaceae based on both molecular and ultrastructural data.
Journal ArticleDOI
Angiosperm phylogeny based on matK sequence information
Khidir W. Hilu,Thomas Borsch,Kai F. Müller,Douglas E. Soltis,Pamela S. Soltis,Vincent Savolainen,Mark W. Chase,Martyn P. Powell,Lawrence A. Alice,Rodger C. Evans,Hervé Sauquet,Christoph Neinhuis,Tracey A. Bodo Slotta,Jens G. Rohwer,Christopher S. Campbell,Lars W. Chatrou +15 more
TL;DR: Combined analyses of matK and other rapidly evolving DNA regions with available multigene data sets have strong potential to enhance resolution and internal support in deep level angiosperms phylogenetics and provide additional insights into angiosperm evolution.
Journal ArticleDOI
Phylogeny of the eudicots : a nearly complete familial analysis based on rbcL gene sequences
Vincent Savolainen,Michael F. Fay,Dirk C. Albach,Anders Backlund,M. Van der Bank,Kenneth M. Cameron,Sheila A. Johnson,Maria Dolores Lledó,J-C Pintaud,Martyn P. Powell,Mary C. Sheahan,Douglas E. Soltis,Pamela S. Soltis,Peter H. Weston,William Mark Whitten,Kenneth J. Wurdack,Mark W. Chase +16 more
TL;DR: A phylogenetic analysis of 589 plastid rbcL gene sequences representing nearly all eudicot families was performed, and bootstrap re-sampling was used to assess support for clades.
Journal ArticleDOI
Causes of Plant Diversification in the Cape Biodiversity Hotspot of South Africa
Jan Schnitzler,Jan Schnitzler,Timothy G. Barraclough,Timothy G. Barraclough,James S. Boatwright,Peter Goldblatt,John C. Manning,Martyn P. Powell,Tony G. Rebelo,Vincent Savolainen,Vincent Savolainen +10 more
TL;DR: It is concluded that the combination of complex environmental conditions together with relative climatic stability promoted high speciation and/or low extinction rates as the most likely scenario leading to present-day patterns of hyperdiversity in the Cape.
