Congratulations to Lauren Gonzalez who was recently awarded a Graduate Student Research Award from the Society of Systematic Biologists for her proposal titled “Elucidating the Evolutionary History of Tropaeolum (Tropaeolaceae): Implications for Historical Biogeography, Trait Evolution, and Conservation”
Tropaeolum (Tropaeolaceae) comprises ~ 90 species native to Central and South America that are distributed throughout the Andes, within a variety of different habitat types, including several biodiversity hotspots. They also show great variation in floral morphology (e.g. color, shape, size) and some species have been important cultivars around the world. Because of its distribution and diversity, this genus represents an ideal system to study how geological and environmental processes have affected plant evolution in South America. The goals of this study are to resolve the phylogeny of Tropaeolum using a next-generation sequencing approach and subsequently explore biogeography, trait evolution, and conservation status.
Doug and the lab were featured today on the front page of the Gainesville Sun!
Here’s the article:
This weekend a lot of people from the lab headed over to Anastasia State Park near St. Augustine to enjoy some time on the beach. Thanks Miao for the photo!

Here’s a photo a good portion of the lab. It was taken at a start of the year party at Pam and Doug’s.
Ryan 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.

“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.”

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.
This happened a few months ago, but just now getting around to posting the photo. This was from the after run breakfast party.
