Eelgrass Response to Changing Environmental Drivers: Lessons from PNW Mesocosm Studies

Thursday, April 19, 2018 3:30 PM - 4:30 PM

Seagrass communities are ecosystem engineers that provide important services in a dynamic estuarine environment.  Seagrass is often seen as a sentinel species or indicator of estuarine health.  Estuaries are increasingly impacted by natural and anthropogenic stressors, and loss of critical seagrass habitat has been documented at the local, regional, national and global scale.  The interaction of 3 “master variables”, light temperature and nutrients generally control seagrass health and productivity.  Despite more than 30 years of work, our understanding of how these variables interact to influence seagrass productivity is still rather rudimentary.  This presentation synthesizes my research on how native eelgrass Zostera marina L. responds to nutrient and thermal stressors across the scale of individuals to simulated communities and highlights some unexpected results.
