Effect of tissue decomposition on stable isotope signatures of striped dolphins Stenella coeruleoalba and loggerhead sea turtles Caretta caretta

open access: yesAquatic Biology, 2013
Marine mammals and turtles are often studied using the carcasses of stranded dead individuals. Since decomposition processes might modify the stable isotope ratios of tissues, the present study tested the effects of decomposition on carbon (Δsup>13C) and

25 Years authentication of wine with stable isotope analysis in the European Union – Review and outlook

open access: yesBIO Web of Conferences, 2015
The implementation of stable isotope applications in official food analyses began in 1990. At that time the first method to detect sucrose from sugar beet or sugar cane in wine by Deuterium-Nuclear Magnetic Resonance (2H-NMR) of ethanol, also known as ...

ISOTOPIC CHARACTERIZATION OF ORGANIC MATERIALS LEACHED FROM LEAVES IN WATER OF MUNDARING WEIR DAM

open access: yesIndonesian Journal of Chemistry, 2010
This study examined the organic constituents aquatically leached from leaf components of two tree species (wandoo eucalyptus and pinus radiate). In particular this study aimed to assess the stable isotope composition behaviour of dissolved organic carbon

Competition and Predation in Soil Fungivorous Microarthropods Using Stable Isotope Ratio Mass Spectrometry

open access: yesFrontiers in Microbiology, 2019
The soil food web is often described as having three main energy channels: root, bacterial and fungal. Here we provide quantitative data using a sensitive stable isotope ratio mass spectrometry procedure with microcosms on species interactions in the ...
