Isotope ratios of actively cycled elements vary as a function of the biogeochemical
processes in which they participate and the conditions under which those processes occur …

Analyses of the natural variation in stable isotopes of components of ecological systems
have provided new insights into how these systems function across paleoecological to …

The use of stable isotope ratio analysis in archaeology has exploded over the past few
decades to the point where it is now an established tool that is routinely used to investigate …

While past experiments on animals, birds, fish, and insects have shown changes in stable
isotope ratios due to nutritional stress, there has been little research on this topic in humans …

School burnout has been studied extensively in schools but its relation to learning and
studying processes at the university level is still an under-researched topic. The purpose of …

Naturally occurring variations in the stable isotope composition of fossil vertebrates have
been studied since the late 1970s. Isotopic data from vertebrate fossils are sometimes used …

The investigation of organic residues associated with archaeological pottery using modern
analytical chemical methods began in the 1970s. It was recognised early on that the …

Abstract Carbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally
measured in human hair that reflected the period from pre‐conception to delivery in 10 …

Little is known about woolly mammoth (Mammuthus primigenius) mobility and range. Here
we use high temporal resolution sequential analyses of strontium isotope ratios along an …

We develop and test a model to predict the geographic region-of-origin of humans based on
the stable isotope composition of their scalp hair. This model incorporates exchangeable …
