The abundance of mixotrophic algae drives the carbon isotope composition of the copepod Boeckella gracilipes in shallow Patagonian lakes
(Oxford University Press, 2015-02-12)
The importance of allochthonous versus authochthonous carbon in the diet of zooplankters has been discussed at length in the recent literature, the more so for lakes with dissolved organic matter (DOM) concentrations between ...
Carbon Stocks and Isotopic Composition of the Organic Matter in Soils Covered by Native Vegetation and Pasture in Sorocaba, SP, Brazil
(UNIV TEHRAN, 2009)
Land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. The goal of this study was to compare the carbon stock and the isotopic signature of the organic ...
Seasonal moisture sources and the isotopic composition of precipitation, rivers, and carbonates across the Andes at 32º-35.5°S
(American Geophysical Union, 2013-04)
Constraining the influence of different moisture sources across the flanks of mountain ranges is important for understanding tectonic, geomorphic, and paleoclimate problems at geologic timescales, as well as evaluating ...
New data on food consumption in pre-Hispanic populations from northwest Argentina (ca. 1000–1550 A.D.): the contribution of Carbon and Nitrogen Isotopic composition of human bones
(Hindawi Publishing Corporation, 2013-08)
We present data on carbon and nitrogen isotopic composition of human bones from Tolombón (Calchaqui Valley, Salta) and Esquina de Huajra (Quebrada de Humahuaca, Jujuy) sites located in Northwest Argentina (NWA). Both are ...
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 ...

Slab decarbonation and CO2 recycling in the Southwestern Colombian volcanic arc
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-02-01)
The contribution of subducted carbonate sediments to the genesis of the Southwestern Colombian arc magmas was investigated using a comprehensive petrography and geochemical analysis, including determination of major and ...
