Influence of terrestrial vegetation on leaf wax δD of Holocene lake sediments

► Leaf-wax δD and δ13C were negatively correlated. ► A shift in vegetation composition and/or physiology influenced leaf wax δD values. ► Precipitation δD and evaporation affected leaf wax δD to a varying degree. ► Paleoecological data may aid paleoclimatic interpretation of leaf wax δD values.
