The objectives of this research project are to: (1) gain an understanding of how complex community relationships in coastal salt marshes affect nutrient dynamics; and (2) use this understanding to improve habitat restoration and pollution management.
I am examining the interactions of four groups of organisms in the low to midintertidal zone of southern California salt marshes: vascular plants, macroalgae, microalgae, and benthic invertebrates. In a series of field and greenhouse experiments, I am assessing the relative importance of representatives within these groups on nutrient partitioning within the biotic and abiotic compartments of the community. Experiments include the use of isotope labeling techniques to trace the fate of nutrients in the systems. Numerical approximation techniques will be used to combine the different components of salt marsh nutrient cycling in a simulation model.
