Mandelian genetics, yep.

We have broad interests in plant ecology, evolution, and biodiversity. In the field, the greenhouse, and the lab we ask questions about mechanisms that drive and maintain biodiversity. We use genetics and genomics as tools to understand the processes that lead to the remarkable genetic, phenotypic, and ecological diversity present in nature.

The Mandel lab studies sunflowers and their relatives to understand mechanisms that drive and maintain biodiversity in the sunflower family. The Asteraceae is the largest family of flowering plants with more than 25,000 species distributed worldwide. We also have interests in the genetics of crops and their wild relatives, as well as, organellar genome diversity and evolution in plants. For more information about what we do, check out our Research, People, and Publications pages.

Work from Nantucket on pollinator visitation in the presence of non-native species is out by Adam Ramsey and Mike Ballou. Check out their findings in Rhodora.

To address whether the presence of D. carota affects the pollination of native species on Nantucket, we sought to answer three questions: 1) Does the presence of D. carotaincrease pollinator visits and diversity on Sericocarpus asteroides? 2) Does the removal of D. carota restore pollinator visits and diversities to those found in plots with only S. asteroides? and 3) Is there a relationship between the amount of heterospecific pollen and distance to the nearest D. carota population?

 

 

 

Carol Siniscalchi’s paper in Frontiers in Plant Sciences is published.¬†

In this study, we present the first attempt at studying the phylogeny of Vernonieae using phylogenomics. Even though our sampling includes only around 4% of the diversity of the tribe, we achieved complete resolution of the phylogeny with high support recovering approximately 700 nuclear markers obtained through target capture. We also analyzed the effect of missing data using two different matrices with different number of markers and the difference between concatenated and gene tree analysis.
