Microsatellite genotyping of six pristine and seven oiled saltmarsh greenhead (T. nigrovittatus) populations detected genetic bottlenecks in five of the oiled populations after the Deepwater Horizon disaster. We propose to follow up that study with a longitudinal population genetic study of horse flies as bioindicators of marsh health and recovery. We will use this information to develop a time- and cost-efficient PCR-based diagnostic method to differentiate between healthy and biologically depleted marsh soil for use in intensive sampling. The development of PCR diagnostic tools for food web detection fits our reductionist approach to develop and verify tools that can be used by coastal ecologists to evaluate tidal marsh health.
