This project aims to investigate how plant litter breakdown in wetlands controls soil carbon preservation by identifying the climatic, environmental and microbial drivers of decomposition on a global scale. This project will generate new knowledge in the area of freshwater and coastal wetland ecology using interdisciplinary approaches in biogeochemistry and microbial ecology. Outcomes of this project include novel global datasets that will identify why some wetlands preserve carbon better than others and what management practices can enhance sequestration capacity. This should provide significant benefits, including advancing carbon-cycling models and predictions, and improving capacity to manage and restore wetland function.

该项目旨在通过确定全球范围内分解的气候，环境和微生物驱动因素，调查湿地中植物凋落物分解如何控制土壤碳保存。该项目将利用生物地球化学和微生物生态学的跨学科方法，在淡水和沿海湿地生态学领域产生新的知识。该项目的成果包括新的全球数据集，这些数据集将确定为什么某些湿地比其他湿地更好地保护碳，以及哪些管理做法可以提高固碳能力。这将带来巨大的好处，包括推进碳循环模型和预测，提高管理和恢复湿地功能的能力。
