Dependence of tree ring stable isotope abundances and ring width on climate
Summary We measured ring widths and isotopic abun-dances of carbon, oxygen and hydrogen (δ13C, δ18O and δ2H) from the latewood of tree rings of pedunculate oak (Quercus robur L.) in its distributional northern limit in Southern Finland. Ring width was observed to be related to precipitation and rela...
