The Soltis Lab

Scientists and students in the Soltis Lab are currently working with a variety of technologies to investigate mechanisms of speciation, evolutionary relationships and character evolution in flowering and land plants at all taxonomic levels. Current projects include the study of higher level phylogenetic relationships and character evolution in the angiosperms, floral evolution, the genetic and genomic consequences of polyploidy, conservation genetics of rare plants, phylogeography, and biogeography. Please explore our website for more information on our research.

New species named in honor of Doug: Heuchera soltisii

August 21st, 2015
By Gitzendanner, Matt

H.soltisiiRyan Folk, who happens to be a new post-doc in the lab, and Patrick Alexander have named a new species of Heuchera in honor of Doug: Heuchera soltisii.

Folk, R. A., and P. J. Alexander. 2015. Two New Species, Heuchera soltisii and H. inconstans, with Further Taxonomic Notes for the Western Group of Heuchera Section Heuchera (Saxifragaceae). Systematic Botany 489–500. [View on publisher’s site]

Etymology—This species is named for Douglas Edward Soltis, who, in addition to his early biosystematic work on Sullivantia Torr. & Gray and the Heuchera group of genera, contributed the earliest molecular-systematic studies on saxifrages, greatly improving our understanding of their natural relationships and providing molecular evidence on the importance of hybridization in their history.”

The fate of polyploid lineages: A response to Mayrose et al. (2014)

Douglas E. Soltis, María Claudia Segovia-Salcedo, Ingrid Jordon-Thaden, Lucas C. Majure, Nicolas M. Miles, Evgeny V. Mavrodiev, Wenbin Mei, Mark E. Mort, Pamela S. Soltis, Graham R. Jones, Thomas Marcussen, Bengt Oxelman, and Matthew A. Gitzendanner. The fate of polyploid lineages: A response to Mayrose et al. (2014). Online at: http://www.flmnh.ufl.edu/museum-voices/soltis-lab/2015/07/29/the-fate-of-po…ose-et-al-2014/

Mayrose et al. (2011) and Arrigo and Barker (2012) concluded that neopolyploid lineages diversify more slowly than the diploid lineages from which they arise. We expressed concerns about this statement in Soltis et al. (2014a) to which Mayrose et al. (2014) responded. This article continues the discussion. We demonstrate a statistical problem with the original analysis which has not been discussed before. We point out that restricting to cpDNA data does not resolve the reticulation issue, contrary to Mayrose et al. (2014). Furthermore, we discuss some clade-specific problems with the data set used in the original analysis.
