Our three-year program on the Evolution of Floral Form and Function has been recently funded by the Yale Institute for Biospheric studies.  This represents a collaboration between the labs of Craig Brodersen (School of Forestry and Environmental Studies, Yale) and Madhusudhan Venkadesan (School of Engineering and Applied Sciences, Yale) and will address tradeoffs in the structure and physiological function of flowers over macroevolutionary times scales.

Chris DiVittorio (UC-MEXUS, UC-Riverside) and I spent March 2015 in Baja Mexico studying the charismatic desert genus Encelia, a classical case of adaptive radiation. While there, we rediscovered a rare species in the genus, Encelia densifolia. We measured and mapped every known individual of the species, which occurs in a single population in the Sierra de Santa Clara mountains of Baja California Sur.  This short piece introduces the system and its unique potential for studying the processes of speciation and extinction.
