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 …

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 …

Soil-Plant-Atmosphere Conditions Regulating Convective Cloud Formation Above Southeastern US Pine Plantations
Manoli, G., Domec, J.C., Novick, K.A., Oishi, A.C., Noormets, A., Marani, M., Katul, G.

Loblolly pine trees (Pinus taeda L.) occupy more than 20% of the forested area in the Southern United States, represent more than 50%of the standing pine volume in this region, and remove from the atmosphere about 500 g C m−2 per year through net ecosystem CO2 exchange. Hence, their significance as a major regional carbon sink …

Seasonality of temperate forest photosynthesis and daytime respiration
Wehr, R., Munger, J. W., McManus, J. B., Nelson, D. D., Zahniser, M. S., Davidson, E. A., Wofsy, S. C., Saleska, S. R.

Terrestrial ecosystems currently offset one-quarter of anthropogenic carbon dioxide (CO2) emissions because of a slight imbalance between global terrestrial photosynthesis and respiration. Understanding what controls these two biological fluxes is therefore crucial to predicting climate change. Yet there is no way of directly measuring …

Slow ecosystem responses conditionally regulate annual carbon balance over 15 years in Californian oak-grass savanna
Ma, S, Baldocchi, D.D., Wolf, S., Verfaillie, J.

Many ecophysiological and biogeochemical processes respond rapidly to changes in biotic and abiotic conditions, while ecosystem-level responses develop much more slowly (e.g., over months, seasons, years, or decades). To better understand the role of the slow responses in regulating interannual variability in NEE, we partitioned …

Terrestrial Carbon Cycle Variability
Baldocchi, D., Ryu, Y, Keenan, T

A growing literature is reporting on how the terrestrial carbon cycle is experiencing year-to-year variability because of climate anomalies and trends caused by global change. As CO2 concentration records in the atmosphere exceed 50 years and as satellite records reach over 30 years in length, we are becoming better able to address …

Warm spring reduced carbon cycle impact of the 2012 US summer drought
Wolf, S., Keenan, T.F., Fisher, J.B., Baldocchi, D.D., Desai, A.R., Richardson, A.D., Scott, R.L., Law, B.E., Litvak, M.E., Brunsell, N.A., Peters, W., van der Laan-Luijkx, I.T.

The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting …

Short-term favorable weather conditions are an important control of interannual variability in carbon and water fluxes
Zscheischler, J., Fatichi, S., Wolf, S., Blanken, P., Bohrer, G., Clark, K., Desai, A., Hollinger, D., Keenan, T., Novick, K.A., Seneviratne, S.I.

Ecosystem models often perform poorly in reproducing interannual variability in carbon and water fluxes, resulting in considerable uncertainty when estimating the land-carbon sink. While many aggregated variables (growing season length, seasonal precipitation, or temperature) have been suggested as predictors for interannual variability …
