CO2 And N2O Flux Balance On Soybean Fields During Growth And Fallow Periods In The Argentine Pampas—A Study Case
Lewczuk. N.A., Posse, G., Richter, K., Achkar, A.

The estimation of the GHG balance of agroecosystems is essential to evaluate the impact of agriculture on the composition of the atmosphere. Cultivated soils may act as a sink or a source of CO2 and usually emit N2O. The aim of the present study was to assess the CO2 and N2O balances, and to analyze the
relationships between N2O …

Do Dynamic Global Vegetation Models Capture The Seasonality Of Carbon Fluxes In The Amazon Basin? A Data‐Model Intercomparison
Restrepo‐Coupe, N., Levine, N. M., Christoffersen, B. O., Albert, L. P., Wu, J., Costa, M. H., Galbraith, D., Imbuzeiro, H., Martins, G., da Araujo, A. C., Malhi, Y. S., Zeng, X., Moorcroft, P., Saleska, S. R.

To predict forest response to long-term climate change with high confidence requires that dynamic global vegetation models (DGVMs) be successfully tested against ecosystem response to short-term variations in environmental drivers, including regular seasonal patterns. Here, we used an integrated dataset from four forests in the Brasil …

Potential Bias Of Daily Soil Co2 Efflux Estimates Due To Sampling Time
Cueva, A., Bullock, S. H., López-Reyes, E., Vargas, R.

Soil respiration (Rs) has been usually measured during daylight hours using manual chambers. This approach assumes that measurements made during a typical time interval (e.g., 9 to 11 am) represent the mean daily value; locally, this may not always be correct and could result in systematic bias of daily and annual Rs budgets. We …

Direct And Indirect Climate Change Effects On Carbon Dioxide Fluxes In A Thawing Boreal Forest-Wetland Landscape
Helbig, M., Chasmer, L. E., Desai, A. R., Kljun, N., Quinton, W. L., Sonnentag, O.

In the sporadic permafrost zone of northwestern Canada, boreal forest carbon dioxide (CO2 ) fluxes will be altered directly by climate change through changing meteorological forcing and indirectly through changes in landscape functioning associated with thaw-induced collapse-scar bog (‘wetland’) expansion. However, their combined …

Short‐Term Selective Thinning Effects On Hydraulic Functionality Of A Temperate Pine Forest In Eastern Canada
Skubel, R. A., Khomik, M., Brodeur, J. J., Thorne, R., Arain, M. A.

Forest plantations are commonly used to restore the ecological and hydrological functionality of landscapes. In this study, we investigated the hydrologic response of a 74-year old pine plantation forest in southern Ontario, Canada to a selective thinning, wherein 30% of trees were harvested in winter of 2012. Tree-level and ecosystem-level …

Representing Winter Wheat In The Community Land Model (Version 4.5)
Lu, Y., Williams, I. N., Bagley, J. E., Torn, M. S., Kueppers, L. M.

Winter wheat is a staple crop for global food security, and is the dominant vegetation cover for a significant fraction of Earth’s croplands. As such, it plays an important role in carbon cycling and land–atmosphere interactions in these key regions. Accurate simulation of winter wheat growth is not only crucial for future yield …
