This research aims to advance our understanding of how temperate marine plants in their northern limit will respond to the effects of synergistic stressors from extreme events combined with climate change. The research will be conducted in the UNESCO World Heritage site of Shark Bay, where a semi-permanent, salinity gradient maintained by shallow seagrass banks has resulted in unique ecosystems like stromatolites to persist. The project will generate new knowledge in the area of adaptation and acclimation to climate change using a multidisciplinary, whole plant approach to examine the links between phenotypic plasticity, ecophysiological traits, and its genome. Expected outcomes include practical solutions for building resilience to climate change mitigation in marine ecosystems.
