Aberrant water homeostasis detected by stable isotope analysis. [PDF]
PLoS ONE, 2010 While isotopes are frequently used as tracers in investigations of disease physiology (i.e., 14C labeled glucose), few studies have examined the impact that disease, and disease-related alterations in metabolism, may have on stable isotope ratios at ...

The 15N gas-flux method to determine N2 flux: a comparison of different tracer addition approaches [PDF]
SOIL, 2020 The 15N gas-flux method allows for the quantification of N2 flux and tracing soil N transformations. An important requirement for this method is a homogeneous distribution of the 15N tracer added to soil.

N2O isotope approaches for source partitioning of N2O production and estimation of N2O reduction – validation with the 15N gas-flux method in laboratory and field studies [PDF]
Biogeosciences, 2020 The approaches based on natural abundance N2O stable isotopes are often applied for the estimation of mixing proportions between various N2O-producing pathways as well as for estimation of the extent of N2O reduction to N2.

Nitrite isotope characteristics and associated soil N transformations
Scientific Reports, 2021 Nitrite (NO2 −) is a crucial compound in the N soil cycle. As an intermediate of nearly all N transformations, its isotopic signature may provide precious information on the active pathways and processes.

Microbial carbon recycling – an underestimated process controlling soil carbon dynamics – Part 1: A long-term laboratory incubation experiment [PDF]
Biogeosciences, 2015 Independent of its chemical structure carbon (C) persists in soil for several decades, controlled by stabilization and recycling. To disentangle the importance of the two factors on the turnover dynamics of soil sugars, an important compound of soil ...

Microbial carbon recycling: an underestimated process controlling soil carbon dynamics – Part 2: A C3-C4 vegetation change field labelling experiment [PDF]
Biogeosciences, 2015 The mean residence times (MRT) of different compound classes of soil organic matter (SOM) do not match their inherent recalcitrance to decomposition. One reason for this is the stabilization within the soil matrix, but recycling, i.e.

Stable isotope analysis of dynamic lipidomics [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2017 Metabolic pathway flux is a fundamental element of biological activity, which can be quantified using a variety of mass spectrometric techniques to monitor incorporation of stable isotope-labelled substrates into metabolic products. This article contrasts developments in electrospray ionisation mass spectrometry (ESI-MS) for the measurement of lipid ...

Stable isotope analysis (δ13C and δ15N) of soil nematodes from four feeding groups [PDF]
PeerJ, 2016 Soil nematode feeding groups are a long-established trophic categorisation largely based on morphology and are used in ecological indices to monitor and analyse the biological state of soils.
