Broad Goal


The focus of our research program is to investigate the interactions of bottom-up and top-down trophic forces within terrestrial ecosystems. Through examinations of the mechanisms of inter-trophic relationships we can better define management implications for ecosystem function in both managed and unmanaged landscapes.
