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

海草床在全球碳(C)和氮(N)循环中起着至关重要的作用。目前尚不清楚这种作用如何受到人类造成的营养输入的影响。这项研究旨在现场确定营养物质的增加如何影响海草床的C和N循环。将使用一套新的尖端方法，包括全生态系统稳定同位素标记。该项目意义重大，因为海草床影响输出到海洋或埋藏的碳和氮的数量和形态，从而影响全球预算。其结果将是在理解全球碳和氮循环方面取得的重大进展。好处是，这将通过提高我们预测营养物质如何影响海草生态系统服务的能力，促进有效的海岸管理。

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.
