Effect of climate change on delivery and degradation of lipid biomarkers in a Holocene peat sequence in the Eastern European Russian Arctic

► A suite of lipid biomarkers from a European Russian Arctic peat core was analyzed. ► The peat sequence records a vegetation transition from a wetter fen to a drier bog. ► The n-alkan-2-ones derive from oxidation of n-alkanes and decarboxylation of n-acids. ► Both n-alkanoic acids and n-alkanols are useful paleoenvironmental proxies.
