RESUMO
δ13C values of the lichens Ramalina duriaei and Teloschistes villosus collected in their natural habitat were repeatedly measured during 2 years. Results show variations in the stable carbon isotope ratios (13C/12C). Such variations are correlated to the seasonal rainfall, i.e. low values of δ13C of the lichens during the winter and high values of δ13C during the dry summer. Relatively low δ13C values were obtained also in laboratory experiments with lichens grown under controlled humid conditions and in lichens collected from humid habitats.
