Tracing the regional origin of everything from milk to invasive bugs is now possible thanks to a University of Otago project. A strontium isotope map developed by Ph.D. Candidate Robyn Kramer, and ...

Scientists from Northwestern have published new findings on the factors that triggered the oceanic anoxic event (OAE) 1a in the Early Cretaceous Period about120 million years ago. The unprecedented ...

Strontium isotopes are frequently used in archaeological studies to establish the provenance and migration history of prehistoric people and artifacts. Many of these studies may be based on incorrect ...

UC Santa Cruz Anthropology Professor Vicky Oelze prepares samples for a strontium isotope analysis. Postdoctoral fellow Xueye Wang and UCSC graduate and undergraduate students processed hundreds of ...

This geological map of equatorial Africa shows strontium isotope sampling locations Oelze’s team will use to create the first-ever strontium isotope map of the region, a tool researchers will use to ...

The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United ...

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.

Scientists have created a groundbreaking map of strontium isotopes found across sub-Saharan Africa—which could help descendants of enslaved people reconstruct their family histories. Strontium is an ...

A person's hands cup a sample of pelletized agricultural fertlizer and a piece of the phosphate rock from which it is created. DURHAM N.C. – An international team of scientists has uncovered toxic ...

A team of researchers has mapped predicted bioavailable strontium isotope ratios across all of Sub-Saharan Africa. Archaeologists, conservation scientists, and forensics experts will now be able to ...
