Next-generation of Oenothera xylocarpa (2016)

Oenothera xylocarpa is a rare endemic found in rich pumice soils found in high elevations of the Sierra Nevada.  This species is only located in three isolated regions in California and Nevada. Using Next-generation sequencing techniques we are interested in exploring how isolated are the populations in these regions and how much diversity remains within these populations. This data will be...


Phylogeny and Genomics of Onagraceae (2015)

New genomics-focused techniques have allowed us to generate large volumes of data for both phylogenetic and functional analysis. In particular, the relatively new field of phylogenomics has allowed us to improve the resolution of relationships between related species, with the emphasis on nodes that have been recalcitrant with more traditional techniques. For this project students will be...


Scent variation: its role in attracting both pollinators and herbivores in Evening Primroses (2015)

The plant tribe Onagreae (Onagraceae; the evening primrose family) and its associated insects pollinators (Sphingidae hawkmoth) and herbivores (Mompha microlepidoptera and Hawkmoth larvae) is a model systems for studying the role of floral scent in shaping the evolution of plants and their associated organisms across western North America. Floral scent is known to be an important trait in...
