Radiative Forcing Of Methane Fluxes Offsets Net Carbon Dioxide Uptake For A Tropical Flooded Forest
Dalmagro, H. J., Zanella de Arruda, P. H., Vourlitis, G. L., Lathuillière, M. J., de S. Nogueira, J., Couto, E. G., Johnson, M. S.

Wetlands are important sources of methane (CH4) and sinks of carbon dioxide (CO2). However, little is known about CH4 and CO2 fluxes and dynamics of seasonally flooded tropical forests of South America in relation to local carbon (C) balances and atmospheric exchange. We measured net ecosystem fluxes of CH4 and CO2 in the Pantanal …

Effects Of Disturbance On The Carbon Dioxide Balance Of An Anthropogenic Peatland In Northern Patagonia
Valdés-Barrera, A., Kutzbach, L., Celis-Diez, J. L., Armesto, J. J., Holl, D., Perez-Quezada, J. F.

Peatlands are characterized by their large carbon (C) storage capacity and represent important C sinks globally. In southern Chile, young peatlands (few centuries old) have originated due to clearcutting or fire at forest sites with high precipitation on poorly drained soils. These novel ecosystems are called anthropogenic peatlands …

A Biogeochemical Compromise: The High Methane Cost Of Sequestering Carbon In Restored Wetlands
Hemes, K. S., Chamberlain, S. D., Eichelmann, E., Knox, S. H., Baldocchi, D. D.

Peatland drainage is an important driver of global soil carbon loss and carbon dioxide (CO2) emissions. Restoration of peatlands by re‐flooding reverses CO2 losses at the cost of increased methane (CH4) emissions, presenting a biogeochemical compromise. While restoring peatlands is a potentially effective method for sequestering …

Impact of land use during winter on the balance of greenhouse gases
Posse, G., Lewczuk. N.A., Di Bella, C., Richter, K., Oricchio, P, Hilbert, J.

The increase in atmospheric greenhouse gases (GHGs) can be mitigated by capturing CO2 from the
atmosphere and/or by reducing their emissions. Replacing winter intercrop fallow by cover crops
(CCs) can sequester carbon and improve nitrogen use efficiency under proper management. We
monitored two cycles of a cash crop namely soybean …

In Situ Observations Reveal How Spectral Reflectance Responds To Growing Season Phenology Of An Open Evergreen Forest In Alaska
Kobayashi, H., Nagai, S., Kim, Y., Yang, W., Ikeda, K., Ikawa, H., Nagano, H., Suzuki, R.

Plant phenology timings, such as spring green-up and autumn senescence, are essential state information characterizing biological responses and terrestrial carbon cycles. Current efforts for the in situ reflectance measurements are not enough to obtain the exact interpretation of how seasonal spectral signature responds to phenological …

Estimating Regional Effects Of Climate Change And Altered Land Use On Biosphere Carbon Fluxes Using Distributed Time Delay Neural Networks With Bayesian Regularized Learning
Schmidt, A., Creason, W., Law, B. E.

he ability to accurately predict changes of the carbon and energy balance on a regional scale is of great importance for assessing the effect of land use changes on carbon sequestration under future climate conditions. Here, a suite of land cover-specific Distributed Time Delay Neural Networks with a parameter adoption algorithm …

Seasonal Variation Of Source Contributions To Eddy-Covariance Co 2 Measurements In A Mixed Hardwood-Conifer Forest
Kim, J., Hwang, T., Schaaf, C. L., Kljun, N., Munger, J. W.

Net ecosystem exchange (NEE) measurements using the eddy covariance technique have been widely used for calibration and evaluation of carbon flux estimates from terrestrial ecosystem models as well as for remote sensing-based estimates across various spatial and temporal scales. Therefore, it is vital to fully understand the land …
