Jesse Leddick - CO2 Lab
University of California, San Diego
Conducted a greenhouse experiment to examine the effects of salinity, sea-level, and elevated carbon dioxide concentrations on the growth and photosynthesis of a brackish marsh sedge, Scirpus olneyi. We discovered that a stimulation of photosynthesis due to high carbon dioxide concentrations enables plants to maintain higher growth rates throughout the growing season, and that this stimulation is relatively more significant under conditions of high salinity stress. Thus, future increases in carbon dioxide concentrations may increase the tolerance of some plant species for salinity stress, which will likely have implications regarding the distribution of plant species and their growth potential.
After finishing my internship, I will be working here at SERC as a research technician within the forest ecology lab during the coming year - next fall, I hope to enter a graduate program in forest ecology and conservation.
