Diego Lirman, Ph.D.
My research is focused on documenting and forecasting the impacts of multiple stressors on the abundance, distribution, and condition of organisms within marine benthic communities. While investigating the impacts of physical disturbance (e.g., hurricanes, ship groundings), biological interactions (e.g., space competition), and other stressors (e.g., salinity fluctuations, sedimentation), I have developed a research methodology that combines field assessments, lab-microcosm exposure experiments, and ecological simulation modelling. Over the past 7 years, I have applied this methodology to the study of the disturbance ecology of seagrasses, sponges, macroalgae, and coral populations of Biscayne Bay, Florida Bay, and the Florida Reef Tract.
My longer-term research goals are to understand how local adaptation to stress may influence the persistence of benthic communities at larger temporal and spatial scales. By documenting the response and adaptive mechanisms of benthic communities in habitats that commonly experience sub-optimal, widely fluctuating environmental conditions at ecological time scales, I hope to gain important insights into the mechanisms that may allow such communities to cope with changes at larger scales such as those arising from Global Change processes.
