Joe Holtum am a plant ecophysiologist interested in the mechanisms that permit plants to survive when times are tough. I have a particular focus on how the roughly 6% of plant species that exhibit a water-conserving type of photosynthesis known as crassulacean acid metabolism (CAM) respond to temperature, water-limitation and to changing concentrations of atmospheric CO2.
