• Large Methane Emissions From Tree Stems Complicate the Wetland Methane Budget (2023) · Journal of Geophysical Research Biogeosciences · cited 24× · doi

  Few studies have combined seasonal measurements of soil, water and tree stem CH 4 emissions from forested wetlands, inhibiting our capacity to constrain the tree stem CH 4 flux contribution to the total wetland CH 4 flux.

• Seasonal changes in tree stem and soil methane fluxes along a soil moisture gradient in a subtropical Australian rainforest (2026) · Biogeochemistry · doi

  This study adds to the limited knowledge of high temporal and spatial heterogeneity of upland tree and soil CH 4 fluxes, and it highlights the importance of rainforest soils as important global CH 4 sink.

• Insights into the subdaily variations in methane, nitrous oxide and carbon dioxide fluxes from upland tropical tree stems (2025) · New Phytologist · cited 15× · doi

  Summary Recent studies have shown that stem fluxes, although highly variable among trees, can alter the strength of the methane (CH 4 ) sink or nitrous oxide (N 2 O) source in some forests, but the patterns and magnitudes of these fluxes remain unclear.
