Undergraduate researcher Hiral Patel’s work on floral trait evolution was featured in the UGA Columns newspaper and website this week. Hiral is currently completing an honors thesis examining the macroevolution of flower size and morphology across the wild sunflowers (Helianthus), and will be giving an oral presentation at the 2015 CURO symposium.
