TL;DR: A review of the most important existing approaches for reconstructing fire history at centennial to millennial scales can be found in this paper, where the authors suggest that emphasis should be laid on discriminating natural from anthropogenic fire-regime types, and improving combined analysis of fire and vegetation reconstructions to study long-term fire ecology.

TL;DR: St isotopic analyses to graphitic black carbon samples isolated from pre-industrial marine and terrestrial sediments find that this material is terrestrially derived and almost entirely depleted of radiocarbon, suggesting that it is graphite weathered from rocks, rather than a combustion product.

TL;DR: The results indicate that rice roots and rhizospheres were less important than the soil-water interface in supporting methanotroph growth, and only type II populations were strongly correlated with soil porewater methane concentrations and rice growth.

TL;DR: In this article, the authors applied solid-state 13 C NMR spectroscopy, along with elemental, stable carbon isotopic (d 13 C) and lignin phenol analyses, to size and density fractions of sediments influenced by either mixed terrestrial and marine organic carbon inputs (Washington Coast slope) or dominantly marine inputs (Mexican margin).

TL;DR: The chemical composition of the graphitic black carbon (GBC) fraction of marine organic matter was explored in several marine and freshwater sedimentary environments along the west coast of North America and the Pacific Ocean.
