TL;DR: In this paper, the authors summarize soil respiration data from four forest free-air carbon dioxide enrichment (FACE) experiments in developing and established forests that have been exposed to elevated atmospheric [CO2] (168l LL � 1 average enrichment) for 2-6 years.

TL;DR: These data illustrate that the hydrological response of a closed-canopy plantation to elevated CO2 depends on the temporal and spatial scale of observation and confirm that integration of measurements over space and time reduce what, at the leaf level, might otherwise appear to be a large and significant response.

TL;DR: In this paper, the relative importance of factors that control soil organic matter decomposition and soil organic carbon turnover was explored in six forest sites in the Southern Appalachian Mountains (USA) and the results supported a conceptual model of vertical changes in forest soil C values, C concentrations, and C:N ratios that are interrelated through climate controls on decomposition.

TL;DR: In this article, the authors characterized peat decomposition at the Marcell Experimental Forest (MEF), Minnesota, USA, to a depth of 2'm to ascertain the underlying chemical changes using Fourier transform infrared (FT IR) and 13C nuclear magnetic resonance (NMR) spectroscopy.

TL;DR: It is shown that deep peat heating of a 2 m-thick peat column results in an exponential increase in CH4 emissions, but this response is due solely to surface processes and not degradation of catotelm peat.
