Abstract

Executive Summary: Climate change is driving the intensification of marine heatwaves (MHWs), which pose a significant threat to seagrass ecosystems globally. Understanding the response of seagrass species to these extreme thermal events is crucial for predicting their resilience and informing conservation strategies. In this study, we evaluated the impacts of prolonged MHW conditions (30 °C) on the photophysiology, metabolism, and growth of three populations of Posidonia sinuosa from Western Australia (Shoalwater, Garden Island, and Jurien Bay). We aimed to determine whether populations with higher thermal optima exhibit higher levels of resilience to MHWs compared to populations with lower thermal optima.
