Dr. Brittany Jellison is a marine scientist that explores how coastal organisms are responding, acclimating, and adapting to human-altered environments. Her work explores how marine ecological interactions are altered by global change, using a variety of mechanistic-laboratory and -field experiments with a focus on factors that influence and alter trophic cascades in coastal systems. Most of the work in her lab concentrates on intertidal/subtidal habitats and marine invertebrate organisms. She uses physiology, animal behavior, and community ecology tools to study these systems and stressors (seawater pH, temperature, nutrient loading) in the Gulf of Maine. Her work seeks to explore questions such as the following: How do species and populations respond physiologically and behaviorally to ocean change? How do multiple stressors in the field alter species interactions and influence community structure? Will specific populations or species be more vulnerable to ocean change?
