Leveraging Multi‐Isotope Systems to Investigate Conflict, Food Insecurity, and Elevated Nitrogen Isotope Values in the Nazca Highlands of Peru During the Late Intermediate Period (1000–1450 CE)

American Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Objectives The physical effects of interpersonal violence are well documented in archaeology, but its broader impacts on population health, mobility, and resource access remain less understood. This article assesses how chronic warfare restricted movement and access to critical resources, altering dietary practices and contributing to ...

Testing the detectability of spatio–temporal climate transitions from paleoclimate networks with the START model [PDF]

Nonlinear Processes in Geophysics, 2014
A critical challenge in paleoclimate data analysis is the fact that the proxy data are heterogeneously distributed in space, which affects statistical methods that rely on spatial embedding of data.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Antarctic last interglacial isotope peak in response to sea ice retreat not ice-sheet collapse

Nature Communications, 2016
The peak in Antarctic ice core isotope values, 128,000 years before present, was concurrent with a significantly warmer-than-present Antarctic climate.

Spatially heterogenous range dynamics since the Last Glacial Maximum underpin the modern bimodal latitudinal diversity gradient in planktonic foraminifera

Ecography, Volume 2026, Issue 11, November 2026.
The modern latitudinal diversity gradient (LDG) of planktonic foraminifera is bimodal, with a distinct depression near the equator surrounded by mid‐latitude diversity peaks. This pattern emerged after the Last Glacial Maximum (LGM; 19–23 ka), but it remains unclear how species' spatial dynamics contributed to its formation.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, Volume 41, Issue 8, Page 1263-1281, November 2026.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Winter Barents–Kara Sea ice loss preconditions a summer drought corridor across Eastern Europe and Eurasia

Frontiers in Water
Droughts are becoming increasingly severe and widespread across Eurasia, with major consequences for agriculture, public health, and regional economies. Although declining Arctic sea ice has been linked to midlatitude climate extremes, the directionality

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, Volume 41, Issue 8, Page 1438-1453, November 2026.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).
