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 ...
Stable isotopes in hair reveal dietary protein sources with links to socioeconomic status and health
(National Academy of Sciences, 2020-08)
Carbon and nitrogen isotope ratios in hair sampled from 65 communities across the central and intermountain regions of the United States and more intensively throughout 29 ZIP codes in the Salt Lake Valley, Utah, revealed ...
Stable isotopes of carbon and nitrogen in the study of organochlorine contaminants in albatrosses and petrels
(2014-04-22)
Carbon and nitrogen stable isotopes in albatrosses and petrels collected off southern Brazil were compared with concentrations of organochlorine contaminants (OCs). d13C and d15N values, as well as OCs concentrations, ...
Stable isotope ecology and human palaeodiet in the northern coast of Santa Cruz (Argentine Patagonia)
(Wiley, 2018-05)
The aim of this paper is to provide information on the analysis of stable isotopes obtained from bones of marine and terrestrial fauna used as potential food by hunter-gatherers on the northern coast of Santa Cruz province ...
Efeito do álcool e formol sobre a composição isotópica de δ 13C e de δ 15N em Plagioscion squamosissimus e Hypophthalmus edentatus (Pisces, Osteichthyes)
(2011-09-14)
The present study investigates the δ 13C and δ 15N isotopic composition in frozen samples (control), samples in alcohol and in formaldehyde of Plagioscion squamosissimus and Hypophthalmus edentatus. From each individual ...
Traceability of animal byproducts in quail (Coturnix coturnix japonica) tissues using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2007-12-01)
Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in ...
Intraspecific isotopic niche variation in broad-snouted caiman (Caiman latirostris)
(Taylor & Francis, 2013-10)
Strategies to minimise intraspecific competition are common in wild animals. For example, individuals may exploit food resources at different levels of the food chain. Analyses of stable isotopes are particularly useful ...
