[PDF][PDF] Origin, fate and significance of CO2 in tree stems.

RO Teskey, A Saveyn, K Steppe, MA McGuire - New Phytologist, 2008 - esalq.usp.br
Although some CO2 released by respiring cells in tree stems diffuses directly to the
atmosphere, on a daily basis 15–55% can remain within the tree. High concentrations of …

Automated measurements of greenhouse gases fluxes from tree stems and soils: magnitudes, patterns and drivers

J Barba, R Poyatos, R Vargas - Scientific Reports, 2019 - nature.com
Tree stems exchange CO2, CH4 and N2O with the atmosphere but the magnitudes, patterns
