Tooth Enamel Carbon and Oxygen Isotope Ratios Reveal Shifts in Neolithic Caprine Husbandry on the Dalmatian Coast, Croatia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Stable isotope analysis of sequential samples of ancient sheep and goat tooth enamel is used to investigate feeding, breeding, and mobility strategies at Neolithic villages on the Dalmatian Coast of Croatia. δ13C values demonstrate clear enrichment of caprine diet in 13C from the Early (c. 8.1–7.5 kya cal.

Total organic carbon, calcium carbonate and compound-specific δ2H on n-alkanes and δ18O on hemicellulose sugars from Late Glacial sediments from Bichlersee, Bavarian Alps

, 2023
Variations in the δ18O signals from lake sediments in the European Alps have been interpreted to reflect past temperature during the Late Glacial–Early Holocene transition due to the strong similarity with δ18O records from Greenland.

Solar cycles in the last centuries in 10Be and δ18O in polar ice and in thermoluminescence signals of a sea sediment [PDF]

, 1984
The cyclogram method of time series analysis has been used to analyse 10Be data (1181–1800 AD) and δ18O data (1181–1960 AD) from an artic ice core and thermoluminescence data (1181–1960 AD) from a Mediterranean sediment core.

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing

Journal of Animal Ecology, EarlyView.
Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.

Simple visualization of fish migration history based on high‐resolution otolith δ18O profiles and hydrodynamic models

Limnology and Oceanography Letters
Oxygen‐stable isotope (δ18O) in otoliths has been useful to infer marine fish migrations. However, because otolith δ18O is affected by two parameters, temperature and δ18O of ambient water, its interpretation becomes challenging when neither of them is ...

The MMCO-EOT conundrum: Same benthic δ18O, different CO2 [PDF]

, 2016
Knowledge on climate change during the Cenozoic largely stems from benthic δ18O records, which document combined effects of deep-sea temperature and ice volume. Information on CO2 is expanding but remains uncertain and intermittent. Attempts to reconcile

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...
