Terrestrial ecosystems encompass a vast and vital component of Earth's biodiversity and
ecosystem services. The effect of increased anthropogenic dominance on terrestrial …

Tam Pà Ling, a cave site in northeastern Laos, has yielded the earliest skeletal evidence of
Homo sapiens in mainland Southeast Asia. The reliance of Pleistocene humans in rainforest …

Stable carbon and nitrogen isotope ratios of collagen from bone and dentin have frequently
been used for dietary reconstruction, but this method is limited by protein preservation …

Diet is a major driver of hominin evolution, but most of the geochemical evidence relies on
carbon isotopes (δ13C). Here, we report enamel stable calcium isotope (δ44/42Ca) values …

Beyond their established uses in Earth and Planetary sciences, calcium (Ca) isotopes have
a promising future in the study of the biology of present and past vertebrates, including …

Diagenesis has been recognized for decades to significantly alter the trace elements
biogenic signatures in fossil tooth enamel and bone that are routinely used for …

The contribution of dairy products to modern human diets has a debated role in the
expansion of Neolithic economies and the dynamics of demographic transitions. While …

Nursing is pivotal in the social and biological evolution of hominins, but to date, early-life
behavior among hominin lineages is a matter of debate. The calcium isotopic compositions …

This paper reports measurements of mass-independent and mass-dependent Ca isotope
variations using the prototype collision cell MC-ICPMS/MS, Proteus. Helium and hydrogen …

Abstract Radiogenic strontium isotopes (87 Sr/86 Sr) are a useful tool in forensics, ecology,
bioarcheology and paleoanthropology allowing investigation of present and past migration …
