A 16th-century Sámi man buried in northern Finland apparently spent part of his youth in Iceland — revealed by anomalous strontium isotopes in his teeth lower than anything measured in Finnish archaeology. New aDNA + isotopes study. #Archaeogenomics #SámiHistory #StableIsotopes https://www.anthropology.net/p/the-kitka-man-went-to-iceland

Shuting Yu et al. analyzed the plant #WaterUseSources and intrinsic #WaterUseEfficiency of five #CoexistingDominantTreeSpecies in #TropicalSecondaryRainforests on Hainan Island during the wet season.

New research applies an economics-based inequality metric to isotope data from 12,281 European skeletons—finding persistent male dominance in high-protein consumption across 10,000 years of prehistory and history. #Bioarchaeology #StableIsotopes #FoodInequality https://www.anthropology.net/p/the-protein-gap

By exploring the water use strategies of five dominant tree species in #TropicalSecondaryForests during the wet season, Shuting Yu et al. found that the dominant tree species primarily utilized shallow soil water compared to deeper soil water.

Neanderthal's high nitrogen values usually lead to them being interpreted as hypercarnivore. But the original study suggests maggots in stored and putrefied meat as cause for the high values:

Die hohen Stickstoffwerte von Neanderthalern führen üblicherweise dazu, dass sie als Hypercarnivoren bezeichnet werden. Aber die Originalstudie legt Maden aus gelagertem & verrottetem Fleisch als Grund für die hohen Werte nahe.

Just out: our latest work reveals environmental changes in southern Patagonia. A fine multi-proxy study led by @NehmeCarole gives you everything: #stableisotopes #clumped #isotopes #fluidinclusions #XRF and more. Proud to be part of such nice team! 😍 https://www.sciencedirect.com/science/article/pii/S0921818123000231?dgcid=author

High-resolution #Isotope analysis of #TreeRings: #StableIsotopes in tree rings provide insights on the #Climate of the past and on physiological reactions of #Trees to climate - here, we give an update on the current status of laser ablation research for high resolution, high throughput analysis of wood carbon isotope ratios: https://academic.oup.com/treephys/advance-article-abstract/doi/10.1093/treephys/tpac141/6909002?login=false
