Carbon and Hydrogen Isotopes as Tracers of Methane Dynamic in Wetlands
(Scientific Research Publishing, 2015-07)
This work presents a review of the main processes leading to the production and sinking of methane in wetlands and how they affect the stable isotope composition of carbon and hydrogen. Isotope fractionation factors ...
Dynamical calculation of direct muon-transfer rates from thermalized muonic hydrogen to C6+ and O8+
(2000-08-01)
Moun-transfer reactions from muonic hydrogen to carbon and oxygen nuclei employing a full quantum-mechanical few-body description of rearrangement scattering were studied by solving the Faddeev-Hahn-type equations using ...

Carbon stable isotopes as indicators of the origin and evolution of CO2 and CH4 in urban solid waste disposal sites and nearby areas
(Springer, 2016-02)
Isotopic compositions of CH4 and CO2 surface and subsurface gases and groundwater from an urban solid waste disposal site from Gualeguaychú city (Argentina) were measured to detect origin, depth distribution, migration ...
Isotopic niches support the resource breadth hypothesis
(Blackwell Publishing Ltd, 2017)
© 2016 The Authors. Journal of Animal Ecology © 2016 British Ecological SocietyBecause a broad spectrum of resource use allows species to persist in a wide range of habitat types, and thus permits them to occupy large ...
Measurements of hydrogen, oxygen and carbon isotope variability in Sphagnum moss along a micro-topographical gradient in a southern Patagonian peatland
(John Wiley & Sons Ltd, 2016-05)
Peat archives offer a diverse range of physical and chemical proxies from which it is possible to study past environmental and ecological changes. Direct numerical calibration and verification is difficult so process-based ...
