The use of biomarkers in combination with stable isotope analysis is a new approach in
microbial ecology and a number of papers on a variety of subjects have appeared. We will …

Some of the ways that the application of stable isotopic tracers have contributed to the
extremely hard task of understanding the energy and food web relations in benthic …

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 …

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 …

This review is concerned with the isotopic relationships between organic compounds
produced by a single organism, specifically their enrichments or depletions in 13C relative to …

The carbon isotopic composition of any naturally synthesized organic compound depends
on (1) the carbon source utilized,(2) isotope effects associated with assimilation of carbon by …

Microbial and phytoplankton processes, and their effect on water quality were examined
over a 3-week period in five high-intensity (120 animals m− 2) shrimp (Litopenaeus …

In order to better estimate bacterial biomass in marine environments, we developed a novel
technique for direct measurement of carbon and nitrogen contents of natural bacterial …

There has been an explosion of research on marine microbial foodweb processes in the
past decade. Today it is widely accepted that about 50% of the primary production in marine …

Stable‐isotope ratios of carbon (13C/12C or δ13C) have been widely used to determine the
energy base of stream food webs, but such use is controversial due to unexplained …
