Short summary
The study evaluates the ability of stable isotopes (δ13C and δ15N) and sugar biomarkers to distinguish Erica from the dominant vegetation of the Bale Mountains in order to reconstruct the past extent of Erica on the Sanetti Plateau. No significant differences in stable isotopes are found between the dominant plant species. Although Erica is characterized by quite high (G+M)/(A+X) ratios, it cannot be unambiguously distinguished from other plants due to degradation and soil microbial effects.
