Intraskeletal variability in stable isotope ratios of C and N among pinnipeds and cetaceans
(Wiley Blackwell Publishing, Inc, 2019-08)
Stable isotope analysis of C and N has become a popular method for addressing questions on the trophic ecology andhabitat use of marine mammals (Newsome, Clementz, & Koch, 2010; Rubenstein & Hobson, 2004). The method ...
Stable isotope compositions of South American camelids in the Dry Puna of Argentina: A frame of reference for the study of prehistoric herding and hunting strategies
(Elsevier, 2018-04)
The prehistoric pastoralist groups that inhabited the Dry Puna of Argentina employed a combination of subsistence strategies that included the herding of domestic South American camelids and the hunting of wild ones since ...
Lama guanicoe bone collagen stable isotope (C and N) indicate climatic and ecological variation during Holocene in Northwest Patagonia
(Pergamon-Elsevier Science Ltd, 2020-05)
This paper explores how significant are the ecological and climatic variables to influence the stable isotopes of guanacos. Lama guanicoe bone collagen carbon and nitrogen stable isotope ratios are assumed as a macro ...
The use of carbon and nitrogen stable isotopes for the detection of poultry offal meal in meat-type quail feeds
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2013-03-01)
The objective of the present study was to trace the inclusion of poultry offal meal (POM) in the diet of meat-type quails reared for a long period using the technique of stable isotopes. A number of 320 quails were randomly ...
Environmental diversity and stable isotope variation in faunas: Implications for human diet reconstruction in Argentine mid-latitude deserts
(Elsevier, 2018-08)
This paper presents the results of an isotopic study of δ13C and δ15N values for bone collagen from 209 modern faunas from central-western Argentina. The samples come from two ecologically distinct areas: the Monte and ...
Stable isotope profiles of partially migratory salmonid populations in Atlantic rivers of Patagonia
(Wiley Blackwell Publishing, Inc, 2008-05)
In the present study, profiles of stable isotope composition were characterized for two species with partially migratory populations in rivers along the latitudinal gradient of Patagonia, brown trout Salmo trutta and rainbow ...

Efficiency of methionine and cystine utilization by broiler chickens using stable isotopes
(2020-01-01)
The aim of this study was to develop a method to determine the efficiency of utilization of Met and Cys using stable isotopes in order to reduce the number of sacrificed animals relative to the comparative slaughter ...
Spatial variation in the strength of mutualism between a jumping spider and a terrestrial bromeliad: Evidence from the stable isotope N-15
(Gauthier-villars/editions Elsevier, 2008-05-01)
Psecas chapoda, a neotropical jumping spider strictly associated with the terrestrial bromeliad Bromelia balansae in cerrados and semi-deciduous forests in South America, effectively contributes to plant nutrition and ...
