Laura Marangoni is a Brazilian coral physiologist studying whether certain coral communities in the Panamanian Pacific have become resistant to climate change. We will join her in an expedition to Coiba National Park to collect corals and back in the laboratory as she explores the ins and outs of their immune system. Her research is part of the ROHR reef resilience project, an ambitious set of experiments in the Tropical Eastern Pacific aiming to uncover how coral reefs cope with environmental change, information that could potentially aid threatened corals around the world.
