Carbon and Nitrogen Stable Isotope Values for Plants and Mammals in a Semi-Desert Region of Mongolia [PDF]

Mongolian Journal of Biological Sciences, 2014
Little information exists on the isotopic signatures of plants and animals in Mongolia, limiting the application of stable isotope analysis to wildlife biology studies. Here we present plant and mammal carbon (δ 13 C) and nitrogen (δ 15 N)

Ecological Niche Changes of Two Sympatric Species (Pennahia argentata and Larimichthys polyactis) Revealed by Bulk and Compound Specific Isotope Analyses

Ecology and Evolution
Sympatric species in marine ecosystems often share habitats and food resources, leading to niche competition. We performed ecological niche width estimation based on bulk carbon (δ13C) and nitrogen (δ15N) isotopes and trophic position estimation via ...

Tracing terrestrial nitrogen contributions to the salt marsh food web of the Obitsu River estuary in Tokyo Bay using compound-specific δ15N analysis of amino acids

Progress in Earth and Planetary Science
Salt marshes, which sustain high productivity, serve as essential living environments for a wide range of organisms. The aquatic food web in salt marshes is basically supported by the high primary production of aquatic algae within the intertidal zone ...

Analytical Considerations of Stable Isotope Labelling in Lipidomics

Biomolecules, 2018
Over the last two decades, lipids have come to be understood as far more than merely components of cellular membranes and forms of energy storage, and are now also being implicated to play important roles in a variety of diseases, with lipid biomarker ...
