“…The omission of GHG fluxes from trees may overestimate the sink potential (Pitz & Megonigal, 2017) and underestimate the release (Covey et al, 2012;Wang et al, 2016) of GHGs from upland and wetland forests, respectively. For instance, tree-mediated CH 4 emissions have been shown to contribute 9-27% (Pangala et al, 2015) and 44-65% (Pangala et al, 2017) of the total ecosystem CH 4 flux in forested temperate and tropical wetlands, respectively. In the broader context of global carbon budgets, forest ecosystems were estimated to emit 6.7 ± 1.1 Pg C/year as CO 2 from tree stems (Yang et al, 2016).…”

The aim of this study was to examine the magnitude of greenhouse gas (GHG) concentrations in tree stems of Pacific Northwest, USA coastal forests and evaluate various tree and site characteristics along river‐to‐sea gradients as possible drivers of tree stem GHG variation. We measured the concentration of CH4, CO2, and N2O during summer and winter in live and dead tree stems of five species from six coastal watersheds and related this to soil porewater GHG concentrations, porewater salinity, and tree characteristics. Overall, average pCO2 and pCH4 were elevated above atmospheric concentration, and average pN2O was slightly below atmospheric concentration. Stem pCO2 was higher in the summer than the winter and was higher in angiosperm trees compared to gymnosperm trees, whereas pCH4 was significantly higher in fresh upstream compared to salt‐influenced reaches. Stem pCH4 was also positively correlated with porewater pCH4 in contrast to other GHGs. The above results suggest that tree stem pCH4 in these coastal settings was primarily controlled by soil linkages, pCO2 was primarily regulated by tree physiology, and factors controlling pN2O remain unclear.

“…However, at present there are currently no published studies on gross primary productivity and net primary productivity in the Cuvette Centrale peatlands. This is not a problem unique to this region; across the globe, few studies have tried to quantify the full carbon budget of a tropical peatland (Bocko et al, 2017;Dargie et al, 2017;Pangala et al, 2017).…”

“…The overlying vegetation also influences peatland GHG emissions: first, by providing substrates for the soil heterotrophic population through litterfall and roots (Girkin et al, 2018). Second through species-specific adaptations found in flood-tolerant plants in tropical peat swamp forest that increase gas exchange under waterlogged conditions, such as enlarged lenticels (stem pores), the presence of aerenchyma (spongy, porous tissue) and pneumatophores (aerial roots specialised for gas exchange; Pangala et al, 2017). These adaptations can affect fluxes by either increasing oxygenation in the rooting zone, potentially increasing CO 2 production or decreasing CH 4 production, or by providing a physical pathway through which CH 4 , produced belowground, can travel to the atmosphere (Girkin et al, 2020).…”

Current knowledge on the Cuvette Centrale peatland complex and future research directions

et al. 2022

View full text Add to dashboard Cite

The Cuvette Centrale is the largest tropical peatland complex in the world, covering approximately 145,000 km2 across the Republic of Congo and the Democratic Republic of Congo. It stores ca. 30.6 Pg C, the equivalent of three years of global carbon dioxide emissions and is now the first trans-national Ramsar site. Despite its size and importance as a global carbon store, relatively little is known about key aspects of its ecology and history, including its formation, the scale of greenhouse gas flows, its biodiversity and its history of human activity. Here, we synthesise available knowledge on the Cuvette Centrale, identifying key areas for further research. Finally, we review the potential of mathematical models to assess future trajectories for the peatlands in terms of the potential impacts of resource extraction or climate change.

Erratum: Large emissions from floodplain trees close the Amazon methane budget

Abstract: In this Letter, owing to an error during the production process, the surname of author Humberto Marotta was incorrectly listed as 'Ribeiro'. This has been corrected in the author list and the Author Contributions section of the original Letter.
