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 ...
Trophic level and isotopic composition of 13C and 15N of pacific angel shark, Squatina californica (Ayres, 1859), in the Southern Gulf of California, Mexico
(Journal of Fisheries and Aquatic Sciences, 2011)
δ13C and δ1NN stable isotopes were used to determine trophic level and the assimilated food components of Pacific angel shark, Squatina californica and its variation between size, sexes and seasonally in the southern Gulf ...
Poultry offal meal traceability in meat quail tissues using the technique of stable carbon (13C/12C) and nitrogen (15N/14N) isotopes
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-03-01)
Studies on the detection of animal by-products in poultry meat are rare, and non-existent on quail meat. This study aimed at detectiong increasing levels of poultry offal meal (POM) in quail meat, using carbon (13C/12C) ...
Poultry offal meal traceability in meat quail tissues using the technique of stable carbon (13C/12C) and nitrogen ( 15N/14N) isotopes

Studies on the detection of animal by-products in poultry meat are rare, and non-existent on quail meat. This study aimed at detectiong increasing levels of poultry offal meal (POM) in quail meat, using carbon (13C/ 12C) ...
Using delta C-13 stable isotopes to quantify individual-level diet variation
(SpringerNew YorkEUA, 2007)
Stable isotopes (δ2H e δ18O) assessment methods in hydrology: a reviewMétodos de avaliação de isótopos estáveis (δ2H e δ18O) na Hidrologia: uma revisão
(Universidade Estadual de Campinas, 2019)
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 ...
Factors controlling the stable isotope composition and C:N ratio of seston and periphyton in shallow lake mesocosms with contrasting nutrient loadings and temperatures
(Wiley Blackwell Publishing, Inc, 2017-09)
Carbon (C) and nitrogen (N) stable isotope composition (15N:14N, δ15N and 13C:12C, δ13C) have been widely used to elucidate changes in aquatic ecosystem dynamics created by eutrophication and climate warming, often, however, ...
Stable isotopes (carbon, nitrogen, sulfur), diet, and anthropometry in urban Colombian women: Investigating socioeconomic differences
(Wiley, 2014-10)
Objectives: We conducted stable isotope and dietary analyses of women from higher and lower socioeconomic status (SES) groups in Cali, Colombia. The objectives were to test between-group differences in stable isotope, ...
Trophic relationships between sperm whales and the jumbo squid using stable isotopes of C and N
(Marine Ecology Progress Series, 2004)
The trophic position and the predator–prey relationship between the sperm whale Physeter macrocephalus and the jumbo squid Dosidicus gigas were examined by measuring stable isotope ratios of carbon and nitrogen. Skin samples ...
