Triterpenols as Proxies for Tracking the Mangrove Evolution in China

Objective Located at the interface of terrestrial and marine ecosystems, mangroves are particularly sensitive to environmental changes. They provide a sedimentary sink for organic carbon, whereby core samples could provide detailed records of mangrove evolution. Human induced, rapid environmental changes in recent years require a better understanding of the mangrove ecosystems evolution in the past, by reconstructing the past mangrove dynamics using triterpenols recorded in sediments. The aim of our work is to improve the application of triterpenols as biomarkers for mangrove development in long term in China.
