Effect of elevated nutrients on carbon and nitrogen cycles in seagrass beds

点击翻译按钮获取中文摘要

Seagrass beds play a crucial role in global carbon (C) and nitrogen (N) cycles. It is unknown how this role is affected by nutrient inputs caused by humans. This study aims to determine, onsite, how elevated nutrients affect seagrass bed C and N cycling. A novel suite of cutting-edge methods will be used, including whole-ecosystem stable isotope labelling. This project is significant because seagrass beds affect the quantity and form of C and N exported to the ocean or buried, thereby impacting global budgets. The outcome will be major advances in understanding global C and N cycles. The benefit is that this will facilitate effective coastal management by improving our ability to predict how nutrients affect seagrass ecosystem services.
