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 ...
Applications of stable isotope analysis in zooarchaeology: An introduction
(Wiley, 2014-03)
This special volume brings together works that present cases of studies that combine analysis of stable isotopes and zooarchaeology in different areas of Chile and Argentina, with special emphasis on the latter. These ...
Groundwater isotope ratios reflect convective and stratiform (paleo)precipitation fractions in Brazil
(2020-06-01)
The stable isotope ratios of oxygen and hydrogen in shallow groundwater reflect the long-term amount-weighted mean isotopic composition of precipitation. Here, we report the isotopic composition of more than 1000 shallow ...
Isotopic carbon turnover in pig hoof and rib
(Editora da Universidade Estadual de Maringá - EDUEM, 2021-06-14)
The objective of this study was to evaluate the behavior of carbon incorporation and turnover in hoof and ribs of pigs at different periods of development in the search for tissues that reflect longer the former diet. We ...
Stable carbon (delta(13)C) and nitrogen (delta(15)N) isotopes as natural indicators of live and dry food in Piaractus mesopotamicus (Holmberg, 1887) larval tissue
(Wiley-Blackwell, 2008-03-07)
This study proposed the use of the stable isotope technique to track the type of food utilized by pacu Piaractus mesopotamicus larvae during their development, and to identify the moment when the larvae start using nutrients ...

The isotopic composition and insect content of diet predict tissue isotopic values in a South American passerine assemblage
(Springer, 2013)
We analyzed the carbon and nitrogen isotopic
values of the muscle, liver, and crop contents (‘‘diet’’) of
132 individuals of 16 species of Chilean birds. The nitrogen
content of diet was tightly correlated with the ...
Patterns of dietary diversity in Holocene north-west South America: new insights from Bayesian stable isotope mixing models
(Cambridge University Press, 2021-05)
For two decades, stable isotope studies have documentedpalaeodietary transitions in the Sabana deBogotá region of north-west South America. Usingtraditional and Bayesian stable isotope mixing models,this article investigates ...
Isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30
(TAYLOR & FRANCIS INC, 2008)
A method for isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30 is reported. The development of this method is for use with studies involving the physiological process of absorption, ...
Endangered species, archaeology, and stable isotopes: Huemul (Hippocamelus bisulcus) isotopic ecology in central-western Patagonia (South America)
(Elsevier, 2011-04)
The management and conservation of animal species should be based upon a long-term analysis that considers its geographical distribution and feeding patterns. The study of carbon and nitrogen stable isotopes on skeletal ...
