Seagrass populations thrive in the shallow coastal regions and offer an ideal habitat for many fish, crustacean and microbes. The worldwide decline of seagrass populations in recent years is therefore of major concern. Researchers believe that climate change plays an important role as the increase in extreme events such as heat waves is a major challenge for the seagrass. How exactly the seagrass species are impacted by extreme events is examined in a new study.
