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 ...
Food web structure in a double-basin ultra-oligotrophic lake in Northwest Patagonia, Argentina, using carbon and nitrogen stable isotopes
(Elsevier, 2013-01)
Fish, benthic macroinvertebrates, macrophytes, biofilm, plankton, and terrestrial material were analyzed for stable nitrogen (15N) and carbon isotopes (13C) to study the food web structure of a double-basined, ultra-oligotrophic ...
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 ...

Benthic foraminiferal stable carbon isotope constraints on deglacial ocean circulation and carbon-cycle changes
(Läderach AG, 2019-11)
How does deep-ocean circulation influence atmospheric CO2 across deglacial transitions? Although biogeochemical and physical processes complicate interpretation of foraminiferal stable carbon isotope data, these complications ...
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, ...
The stable isotope altimeter: Do Quaternary pedogenic carbonates predict modern elevations?
(2009)
Stable isotope altimetry is a useful tool for estimating paleoelevation in sedimentary records. Yet questions remain regarding how source moisture, climate, and local topography can influence these estimates. Here we present ...
