Minoru Yoneda is an Associate Professor at University of Tokyo. His research interests with the project include radiocarbon dating and reservoir effect; carbon, nitrogen, and strontium isotopes…...

To find out what herding strategies may have been used by early Europeans during this period, researchers analyzed strontium isotopes in cattle teeth found in a Neolithic settlement (occupied 3384–3370 BC) in presentday Switzerland. They published their study in PLOS ONE. Strontium signatures reflect local soil and plants, and can vary over relatively short distances, so their patterns …...

Strontium isotope sourcing has become a common and useful method for assigning sources to archaeological artifacts. In Chaco Canyon, an Ancestral Pueblo regional center in New Mexico, previous studies using these methods have suggested that significant portion of maize and wood originate in the...

Analysis of strontium isotopes in teeth from Neolithic cattle suggest that early Europeans used different specialized herding strategies, according to a study published July 26, 2017 in the open ......

Strontium isotope data suggest mixed local and nonlocal origin of the townspeople. Our results uncover the social system underlying the urbanization process of the Viking World of which mobility was an intricate part and was comparable between males and females. The inhabitants of Sigtuna were heterogeneous in their genetic affinities, probably reflecting both close and distant connections ......

In addition to the four stable isotopes, thirtyone unstable isotopes of strontium are known to exist (see Table, below): the longestlived of these are 90 Sr with a halflife of years and 85 Sr …...

This corrects the article "Strontium Isotopes and the Reconstruction of the Chaco Regional System: Evaluating Uncertainty with Bayesian Mixing Models" in volume 9, e95580. The corresponding author’s email is incorrect....

Strontium87 is the product of the radioactive decay of rubidium87 (87 Rb), so strontium isotope ratios (87 Sr/ 86 Sr) vary between different types of bedrock, depending on the initial 87 Sr/ 86 ......

The oxygen (18 O/ 16 O) isotope analysis of hair is commonly applied to reconstruct an individual’s residence history. However, regionoforigin as determined from oxygen isotope values (δ 18 O ......

Strontium isotope ratios (87 Sr/ 86 Sr) are gaining considerable interest as a geolocation tool and are now widely applied in archaeology, ecology, and forensic research. However, their application for provenance requires the development of baseline models predicting surficial 87 Sr/ 86 Sr …...

The IsoFishR application is a data reduction and analysis tool for laserablation strontium isotope data, following common best practices and providing reliable and reproducible results....

Create a simple basemap through broad spatial sampling of animal tissue. 2. Infer a calibration relationship through limited spatial sampling across an isotopic gradient. 3. Experimentally derive the calibration relationship through controlled (captive ......

We are using isotope analysis of strontium in tooth enamel to reconstruct the mobility of hominins and fauna. We conduct these analyses by extracting the strontium through column chromatography or by directly using laser ablation. Additionally, we use sulphur isotopes in bone and tooth collagen as an indicator of migrations....

Dental enamel is currently of high informative value in studies concerning childhood origin and human mobility because the strontium isotope ratio in human dental enamel is indicative of geographical origin. However, many prehistoric burials involve cremation and although strontium retains its...

Isotopes can provide unique solutions to fundamental problems related to the ecology and evolution of migration and dispersal because prior movements of individuals can theoretically be tracked from tissues collected from a single capture. However, there is still remarkably little information...

The main isotope of strontium, 87 Sr, is radiogenic, and as a daughter element created by decay of Rubidium (87 Rb), forms about 7% of total strontium of the planet. Other isotopes of strontium, including 84 Sr, 86 Sr, and 88 Sr, are nonradiogenic ( Slovak and Paytan, 2012 )....

Isotope analysis is the identification of isotopic signature, the abundance of certain stable isotopes and chemical elements within organic and inorganic compounds. Isotopic analysis can be used to understand the flow of energy through a food web, to reconstruct past environmental and climatic conditions, to investigate human and animal diets in the past, for food authentification, and a ......

The findings of the study have been published this week in the journal PLoS One. The settlement, which was occupied for 15 years, had 27 houses and the teeth could be assigned to 12 of them. Strontium signatures reflect local soil and plants, and can vary over relatively short distances....

Strontium (Sr) isotope analysis can provide detailed biogeographical and ecological information about modern and ancient organisms. Because Sr isotope ratios (87 Sr/ 86 Sr) in biologically relevant materials such as water, soil, vegetation, and animal tissues predominantly reflect local geology, they can be used to distinguish geologically ......

Strontium is the chemical element with symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silverwhite yellowish metallic element that is highly chemically reactive....

Two isotopes of strontium, 86 Sr and 87 Sr, are widely used in mobility studies of humans and fauna. Strontium87 is the product of the radioactive decay of rubidium87 ( 87 Rb), so strontium isotope ratios ( 87 Sr/ 86 Sr) vary between different types of bedrock, depending on the initial 87 Sr/ 86 Sr ratio, the Rb/Sr ratio and the age....
