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.

Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

Archaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

A strontium isoscape of Italy for provenance studies

Chemical Geology, 2022
We present a novel database of environmental and geological 87Sr/86Sr values (n = 1920) from Italy, using literature data and newly analysed samples, for provenance purposes. We collected both bioavailable and non-bioavailable (i.e. rocks and bulk soils) data to attain a broader view of the Sr isotope variability of the Italian peninsula.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Deer Antler δ18O Records Desalination in Israel's Water Supply

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.

Assessing the Reliability of Mobility Interpretation From a Multi-Isotope Hair Profile on a Traveling Individual

Frontiers in Ecology and Evolution, 2020
Forensic practitioners, archeologists, and ecologists increasingly use hair isotope profiles and isotope databases and maps to reconstruct the life history of unidentified individuals.

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Community Participation as a Pathway to Strengthen National Precipitation Isotope Products in New Zealand

Journal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
Accurate environmental and climate modelling depends on the availability of large observational datasets, yet the generation of such data is often costly and logistically challenging for individual research groups. This limitation is particularly acute in New Zealand, where geographic isolation, complex topography, and strong climatic gradients require

Groundwater Isoscapes for the Contiguous USA

, 2019
Water extracted from subsurface aquifers has been and continues to be a major source of drinking and irrigation water in locations around the world. Regional studies and global compilations have demonstrated that the stable H and O isotopic composition of groundwaters often differs from that of local precipitation and/or surface water resources due to ...
