We aim to understand how pollution and environmental stressors affect ecosystem function through their direct effects on plants. We use laboratory and field experiments to understand the linkage between environmental conditions, plant function, and molecular response mechanisms. Among the techniques we use are: seagrass andsediment sampling, field fertilization experiments to simulate eutrophication,imaging of seagrasses and their epiphytes, DNA extraction and PCR, rDNA fingerprinting by DGGE , DNA sequencing and genomic comparisons, cloning, gene expression assays, and biochemical analyses.
