TL;DR: It is argued that the magnitude and pattern of increases in forest dynamics across Amazonia observed over the last few decades are consistent with a [CO2]-induced stimulation of tree growth and should more than offset any decline in photosynthetic productivity due to higher D or TL or increased autotrophic respiration rates as a consequence of higher tissue temperatures.

TL;DR: In this paper, the effects of changing fire regime on the stocks and isotopic composition of soil organic carbon (SOC) in a tropical savanna ecosystem at Matopos, Zimbabwe were investigated.

TL;DR: It was estimated that 59% of the net primary productivity of tropical savannas is attributable to C4 grasses, but that this proportion varies significantly within and between regions, and can be broadly ascribed to large scale differences in soil fertility and rainfall.

TL;DR: A three-year trace gas climatology of CO 2 and its stable isotopic ratios, as well as CH 4, N 2 O and SF 6, derived from regular vertical aircraft sampling over the Eurasian continent is presented in this article.

TL;DR: It is concluded that seasonal acclimation of leaf R plays a crucial role in determining the viability of tree growth in dry-land, low productivity forest ecosystems.
