Absence of juvenile effects confirmed in stable carbon and oxygen isotopes of European larch trees

We report carbon and oxygen isotope ratios measured from the pith at breast height (ca. 1.2m) of three European larch (Larix decidua Mill.) trees growing in a mixed wood in West Wales, UK. The non-climatic rising trend of carbon isotope ratios reported for other species during early (juveni...
