“…Relatively, taraxerol is more resistant to microbial degradation and it is the most abundant triterpenol in mangrove sediments, thus making it an ideal marker for mangroves, especially the Rhizophora genus (Johns et al, 1994;Versteegh et al, 2004;Koch et al, 2005Koch et al, , 2011Kristensen et al, 2008;Ranjan et al, 2015;Gayantha et al, 2020). Therefore, taraxerol has been widely used in mangrove studies, e. g., in east Brazil (Koch et al, 2011;Kumar et al, 2019a;Carreira et al, 2021), south China (Chu et al, 2020), south India (Ranjan et al, 2015), and/or to trace mangrove ecosystem changes, e.g., Holocene history in southwest Sri Lanka (Ratnayake et al, 2017(Ratnayake et al, , 2019Gayantha et al, 2020), last deglaciation variation in Congo fan (Kim et al, 2005;Scourse et al, 2005) and Amazon fan (Boot et al, 2006;Maslin et al, 2012), and mid-Pleistocene records in west Africa (Versteegh et al, 2004), etc.…”
