Spatially-Resolved Integrated Precipitation-Surface-Groundwater Water Isotope Mapping From Crowd Sourcing: Toward Understanding Water Cycling Across a Post-glacial Landscape

Frontiers in Water, 2021
Isotopic analyses of δ18O and δ2H of water in the context of the hydrologic cycle have allowed hydrologists to better understand the portioning of water between the different water domains.

A strontium isoscape of inland southeastern Australia

Earth System Science Data, 2022
Abstract. The values and distribution patterns of the strontium (Sr) isotope ratio 87Sr / 86Sr in Earth surface materials is of use in the geological, environmental and social sciences. Ultimately, the 87Sr / 86Sr ratio of soil and everything that lives in and on it is inherited from the rock that is its parent material.

Mediterranean precipitation isoscape preserved in bone collagen δ2H [PDF]

Scientific Reports, 2020
AbstractThe prehistory of the Mediterranean region has long been a subject of considerable interest, particularly the links between human groups and regions of origin. We utilize the spatial variation in the δ2H and δ18O values of precipitation (isoscapes) to develop proxies for geographic locations of fauna and humans.

Visualizing land‐use and management complexity within biogeochemical cycles of an agricultural landscape

Ecosphere, 2016
Crop fields are cultivated across continuities of soil, topography, and local climate that drive biological processes and nutrient cycling at the landscape scale; yet land management and agricultural research are often performed at the field scale ...

Lagoon Biogeochemical Processing is Reflected in Spatial Patterns of Sediment Stable Isotopic Ratios

Journal of Marine Science and Engineering, 2020
The spatial analysis of biota, particulate organic matter, and sediments for stable isotopes of carbon (δ13C), nitrogen (δ15N), and sulfur (δ34S) have proved useful for identifying patterns in productivity, nutrient pollution, and relationships between ...

The Circulation of Ancient Animal Resources Across the Yellow River Basin: A Preliminary Bayesian Re-evaluation of Sr Isotope Data From the Early Neolithic to the Western Zhou Dynasty

Frontiers in Ecology and Evolution, 2021
Many questions still remain regarding the acquisition and circulation of ancient domesticated animals across the Yellow River Basin, one of the key areas for the development of complex societies in ancient China. Here, we re-evaluate previously published

Laser ablation strontium isotopes and spatial assignment show seasonal mobility in red deer (Cervus elaphus) at Lazaret Cave, France (MIS 6)

Frontiers in Ecology and Evolution, 2023
Zooarchaeological analysis is a useful means of exploring faunal palaeoecology, paleoclimate and past human behaviours. The Middle Pleistocene archaeological site Lazaret Cave, located in modern-day Nice, France, features a vast assemblage of faunal ...

Emerging strontium isoscapes of Anatolia (Türkiye): new datasets and perspectives in bioavailable 87Sr/86Sr baseline studies

Frontiers in Environmental Archaeology
IntroductionThe use of strontium isotope ratio (87Sr/86Sr) analysis in ancient mobility studies in the archaeology of Anatolia (modern Türkiye) has steadily grown since the early 2010s.

Combining Models of Environment, Behavior, and Physiology to Predict Tissue Hydrogen and Oxygen Isotope Variance Among Individual Terrestrial Animals

Frontiers in Ecology and Evolution, 2020
Variations in stable hydrogen and oxygen isotope ratios in terrestrial animal tissues are used to reconstruct origin and movement. An underlying assumption of these applications is that tissues grown at the same site share a similar isotopic signal ...

Variability in Bioavailable 87Sr/86Sr in the North American Midcontinent

Open Quaternary, 2017
Strontium (Sr) isotope tracers are useful for understanding provenance and mobility in biological materials across multiple disciplines. However, the impact of these techniques is highly dependent on the construction of appropriate comparative baselines (
