Stable isotope analysis (δ13C and δ15N) of soil nematodes from four feeding groups [PDF]
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.

Isotopic Fingerprinting: A Promising Tool for Coffee Authenticity Checks
Almost every physical or chemical process in nature favors certain light stable isotopes over others, and thereby leaves an isotopic “fingerprint” on the substances involved.

Intracellular carbon storage by microorganisms is an overlooked pathway of biomass growth
The concept of biomass growth is central to microbial carbon (C) cycling and ecosystem nutrient turnover. Microbial biomass is usually assumed to grow by cellular replication, despite microorganisms’ capacity to increase biomass by synthesizing storage ...

Intercropping of legumes and cereals is an important management method for improving yield stability, especially in organic farming systems. However, knowledge is restricted on the relevance of different nutrient transfer pathways.

Ozark hellbenders (Cryptobranchus alleganiensis bishopi) have undergone marked population declines across their entire distribution. A variety of ecological life history research has been conducted to determine the cause(s) of the declines. Historically,

Stable isotope analysis offers a unique tool for comparing trophic interactions and food web architecture in ecosystems based on analysis of stable isotope ratios of carbon (13C/12C) and nitrogen (15N/14N) in organisms.

Aberrant water homeostasis detected by stable isotope analysis. [PDF]
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 ...

Stable isotopes in monitoring terrestrial arthropods
Monitoring of arthropods focuses typically on changes in population and range size over time. Yet, there are a myriad of other aspects that could and should be monitored under the ongoing global and local environmental change.

Stable Isotope Analysis of Water [PDF]
The analysis of stable isotope ratios of hydrogen and oxygen in water can be applied in many research fields. This thesis starts, after some general information about the stable isotopes of water with introducing our measurement techniques. We utilized a laser-based, optical method, which has profound advantages compared to the traditional analysis ...

Applications of stable isotope analysis in mammalian ecology [PDF]
In this editorial, we provide a brief introduction and summarize the 10 research articles included in this Special Issue on Applications of stable isotope analysis in mammalian ecology. The first three articles report correction and discrimination factors that can be used to more accurately estimate the diets of extinct and extant mammals using stable ...
