TL;DR: In this article, the effect of soil moisture on chamber measurements was tested by wetting the fine quartz sand to about 25% volumetric water content, and the results showed that the chamber headspace concentration also affects the flux by altering the concentration gradient between the soil and the chamber.

TL;DR: In a manipulation experiment, the carbon balance of Norway spruce saplings exposed to either drought or carbon starvation (CO2 withdrawal), or both treatments, is manipulated and the dynamics of carbon exchange, allocation and storage in different tissues are compared.

TL;DR: The results indicate that drought-induced changes in carbon allocation, use and transport differ between above- and below-ground tissues in trees, and indicate that mortality mechanisms are not defined at the organism level but rather within tree compartments.

TL;DR: In this article, the authors measured the net CO2 exchange (NEE) over ecosystems differing in land use (forest and agriculture) in Thuringia, Germany, and found that large contrasts were found in NEE rates between the land uses of the ecosystems.

TL;DR: In this paper, data sets of biometeorological measurements of ecosystem CO2 flux, combined with harvest and manure data from several European cropland were integrated to provide an assessment of the carbon budget.
