Description:
Tree height strongly affects estimates of water-use efficiency responses to climate and CO 2 using isotopes Nature Communications, Published online: 18 August 2017; doi:10.1038/s41467-017-00225-z Intrinsic water-use efficiency ( W i ) reconstructions using tree rings often disregard developmental changes in W i as trees age. Here, the authors compare W i across varying tree sizes at a fixed CO 2 level and show that ignoring developmental changes impacts conclusions on trees’ W i responses to CO 2 or climate.
