Published in 2022 at "Rapid Communications in Mass Spectrometry"

DOI: 10.1002/rcm.9286

Abstract: Rationale Dental calculus (mineralised dental plaque) is composed primarily of hydroxyapatite. We hypothesise that the carbonate component of dental calculus will reflect the isotopic composition of ingested simple carbohydrates. Therefore, dental calculus carbonates may be… read more here.

Published in 2017 at "Plant and Soil"

DOI: 10.1007/s11104-017-3418-3

Abstract: AimsStable carbon isotopes are important tracers used to understand ecological food web processes and vegetation shifts over time. However, gaps exist in understanding soil and plant processes that influence δ13C values, particularly across smallholder farming… read more here.

Published in 2019 at "Food chemistry"

DOI: 10.1016/j.foodchem.2019.125106

Abstract: Over 200 sugars, high sugar content foods, and sugar-free alternative products found in Canadian supermarkets were analyzed for carbon isotope (δ13C) values, adding to the record of food items with reported δ13C values, which can… read more here.

Published in 2020 at "Palaeogeography, Palaeoclimatology, Palaeoecology"

DOI: 10.1016/j.palaeo.2020.109857

Abstract: Abstract Insects encode proxy environmental information about regional vegetation structure in the stable carbon isotope (δ13C) composition of their tissues. However, uncertainty lies in the exact relationship between “community” insect δ13C values and the overall… read more here.

Published in 2021 at "Quaternary Research"

DOI: 10.1017/qua.2020.78

Abstract: Abstract Limited numbers of high-resolution records predate the Last Glacial Maximum (LGM) making it difficult to quantify the impacts of environmental changes prior to peak glaciation. We examined sediments from Last Canyon Cave in the… read more here.

Published in 2019 at "Journal of agricultural and food chemistry"

DOI: 10.1021/acs.jafc.9b01631

Abstract: Bell pepper is one of the most cultivated crops in the world. By means of δ13C and δ15N values (‰), red bell peppers from Germany, The Netherlands, and Spain could be distinguished from each other.… read more here.

Published in 2023 at "Isotopes in Environmental and Health Studies"

DOI: 10.1080/10256016.2023.2179045

Abstract: ABSTRACT Eurasian red squirrels Sciurus vulgaris have unusually high δ 13C values compared to other forest rodents, which is seemingly related to the consumption of 13C-enriched conifer seeds. To test this hypothesis, we analyzed the… read more here.

Published in 2022 at "PLoS ONE"

DOI: 10.1371/journal.pone.0270348

Abstract: This study aims to characterize and compare the feeding ecology of the European eels (Anguilla anguilla L.) during the continental phase (i.e. yellow and silver) along a salinity gradient (i.e. lower, middle and upper) in… read more here.
