%0 Journal Article %T Greenhouse Gas Fluxes From Tree Stems %J - %D 2019 %R https://doi.org/10.1016/j.tplants.2019.02.005 %X Tree stems exchange carbon dioxide, methane, and nitrous oxide with the atmosphere. The biophysical mechanisms controlling these fluxes are not fully understood, and consequently are not included in process-based models. We highlight advances and opportunities that will allow quantification of the role of these plant structures in the local-to-global balance of greenhouse gases (GHGs) %U https://www.cell.com/trends/plant-science/fulltext/S1360-1385(19)30032-9
