Inductively coupled plasma mass spectrometry (ICP-MS) is a new technique for elemental
and isotopic analysis which combines the remarkable characteristics of the ICP for atomizing …

Linking their major biotic and abiotic components, food webs form the core of ecosystems,
many of which are today exposed to multiple human impacts acting at several spatial and …

Nitrogen isotope ratios (δ 15 N) are a well-established tool for investigating the dietary and
trophic behavior of animals in terrestrial and marine food webs. To date, δ 15 N values in …

The naturally occurring stable isotopes of potassium (41K/39K, expressed as δ41K) have
the potential to make significant contributions to vertebrate and human biology. The utility of …

Large predators are overabundant in mid-Cretaceous continental dinosaur assemblages of
North Africa. Such unbalanced ecosystem structure involves, among predatory dinosaurs …

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 …

Measurements of modern bone and tooth enamel show that calcium stable isotopes (δ 44
Ca), zinc (δ 66 Zn), and strontium (δ 88 Sr) have great potential as ecological and dietary …

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 …

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

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 …
