Carbon cycling in Arabidopsis thaliana ecotypes

Arabidopsis thaliana, widely used as a genetic model in plant science, has a expansive and environmentally varied natural range. Local populations of A. thaliana ("ecotypes") can be used to compare morphological, phenological, and physiological plasticity across a spectrum of locations representing different temperature, photoperiod, and precipitation regimes. 
            Working with Professor Hilary Callahan at Barnard College, I measured foliar gas exchange under different photoperiod and temperature growth conditions in three ecotypes representing a latitudinal transect from Northern Finland to Germany. This project aligned with multiple undergraduate research projects on intra-species competition between ecotypes and the resulting fitness responses.
