Reconstructing Pleistocene Australian herbivore megafauna diet using calcium and strontium isotopes
Royal Society Open Science, 2023 Isotopes in fossil tooth enamel provide robust tools for reconstructing food webs, which have been understudied in Australian megafauna. To delineate the isotopic composition of primary consumers and understand dietary behaviour at the base of the food ...

Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Hunter-gatherers like the Ju/’hoãnsi (!Kung) San use exchange networks to dampen subsistence and reproductive risks, but almost nothing is known of how, when, and why such practices emerged.

Machine-learning-based automated loading of strontium isotopes into magneto-optical trap
AIP Advances, 2023 We implemented optimization techniques of machine learning (ML) to obtain the mutually exclusive sets of experimental parameters that maximize the number of strontium atoms of different isotopes (88Sr, 86Sr, and 87Sr) in a magneto-optical trap (MOT ...

Lead and strontium isotopes as palaeodietary indicators in the Western Cape of South Africa
South African Journal of Science, 2020 We analysed the isotopic compositions of bioavailable strontium (Sr) and lead (Pb) in 47 samples of animals and plants derived from the various geological substrates of southwestern South Africa, to explore the utility of these isotope systems as ...

Seaweed against strontium and preussian blue against cesium
Rangifer, 1988 The fact that alginates bind strontium and cyanates bind cesium and are capable of removing these elements from living organisms is scientifically verified. Zeolites offer another possibility for exchange of these ions.

Variation of strontium isotopes in tektites [PDF]
Geochimica et Cosmochimica Acta, 1964 Abstract The rubidium, strontium, and strontium isotopic compositions have been determined in tektites from Indo-China, Philippine Islands, Java, Australia, Texas, Georgia, Massachusetts and Czechoslovakia. The range of Sr 87 Sr 86 ratios in 18 tektites is from 0.7121 to 0.7223, indicating the results of Pinson et al.

Silver Linings at the Dawn of a “Golden Age”
Frontiers in Ecology and Evolution, 2021 Nearly four decades after the first applications of strontium isotope analyses in archaeology and paleoecology research, it could be said that we are entering a “Golden Age”.
