Unveiling 2,000 Years of Eelgrass Colonization: Benefits for the Environment and Climate

What is it about?

This study examines the historical colonization of eelgrass in cold coastal regions, focusing on its role in shaping the environment and providing crucial ecosystem services. By analyzing sediment cores from Swedish coastal meadows dating back 14,000 years, we discovered that eelgrass colonization began around 2,000 years ago, leading to significant changes in habitat and sediment composition. This highlights the importance of eelgrass in carbon and nutrient storage, as well as its potential in mitigating climate change impacts. We also assessed the potential effects of climate change on eelgrass health, identifying decreased water clarity and altered water flow as major concerns. This research underscores the importance of conserving and restoring eelgrass habitats for long-term environmental resilience and sustainability.
