Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

Glutamate (Glu) is a versatile metabolite and a signaling molecule in plants. Glu
biosynthesis is associated with the primary nitrogen assimilation pathway. The conversion …

We used radiocarbon (Δ14C) and stable isotopic (Δ13C, Δ15N) signatures of bacterial
nucleic acids to estimate the sources and ages of organic matter (OM) assimilated by …

The factors affecting the amounts and types of organic matter in lacustrine sediments are
summarized in this review, and synthesis, of published studies. Biota living in the lake and in …

Use of stable isotope ratios to trace pathways of organic matter among consumers requires
knowledge of the isotopic shift between diet and consumer. Variation in trophic shift among …

Each year rivers transport approximately 0.25× 1015g of dissolved (< 0.5 μm) organic
carbon (DOC) and 0.15× 1015g of particulate (> 0.5 μm) organic carbon (POC) from …

An Introduction to Organic Geochemistry explores the fate of organic matter of all types,
biogenic and man-made, in the Earth System. investigates the variety of pathways and …

Holocene reconstructions of relative sea-level (RSL) and environmental change in the
coastal zone have become progressively more numerous since the importance of assessing …

Black carbon (BC) is an important pool of the global C cycle, because it cycles much more
slowly than others and may even be managed for C sequestration. Using stable isotope …
