Extinct Species Unearth Bergmann's Rule in Canidae

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Interspecific patterns of Bergmann's rule may be concealed by species extinctions within clades. We evaluate whether incorporating extinct species and paleoenvironmental information improves the detection of Bergmann's rule in the family Canidae, and test whether temperature and net primary productivity (NPP) explain interspecific ...

Morphometric analysis in the shells of the planktonic foraminifera Orbulina universa: a source for paleoceanographic information?

Brazilian Journal of Oceanography
In this study, we describe morphometric analyses of Orbulina universa morphotypes presently found in the Western South Atlantic, and their relation to the upper water thermohaline indexes.

Rapid Changes in Southern Ocean Upper‐Water Temperature Linked to Shift of the Southern Hemisphere Westerlies Since the Last Glacial

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The pattern and cause of upper‐water temperature (UWT) variations on millennial timescales in the Southern Ocean (SO) and the mechanism of their interaction with high‐latitude Northern Hemisphere climate remain unclear. Here, we reconstructed millennial‐scale subsurface temperature (subST) records from the Weddell Sea during the Last Glacial ...

Reconstruction of Late Cretaceous coastal paleotemperature from halite deposits of the Late Cretaceous Nongbok Formation (Khorat Plateau, Laos)

, 2016
Cretaceous evaporites of the Maha Sarakhan Formation in Thailand (e.g., the Nongbok Formation, Laos) have been studied for almost a century as the huge potash deposits in the world.

Food availability impacts oxygen isotope composition in freshwater snail shells

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Freshwater mollusk shells serve as valuable archives for the reconstruction of past environmental conditions as they record water temperatures in their stable isotopic compositions during biomineralization. Yet, the impact of food availability on these isotopic records has never been fully explored.

(Table A1) Stable isotope ratios and paleotemperature calculation of selected planktonic foraminifera from late Campanian and Maastrichtian sediments of DSDP Hole 62-463 from the Mid-Pacific mountains

, 2003
Paleotemperature estimates were calculated using the equation of Erez and Luz (1983), with seawater delta18O = -1.2 per mil PDB corresponding to a continental ice-free world (Shackleton and Kennett, 1975)

Eastern Australian late Holocene paleotemperature variation inferred from borehole temperature data [PDF]

, 2018
Understanding the magnitude, timing and drivers of regional variations in paleotemperature is often challenging because of the lack of a similar proxy in every climate zone and differences in the temperature-proxy response relationship of the multiple ...

Oxygen Isotopic Composition of Miocene Meteoric Water (δ18Ow) in Alpine Foreland Basins

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The reconstructed stable oxygen isotopic composition of meteoric water (δ18Ow) is widely used for paleoclimate reconstructions. Understanding past environmental factors that drove changes in δ18Ow is essential for interpreting past climate conditions.

Non‐Uniqueness, Symmetries and Invariance of Thermal History Modelling in Sedimentary Basins

Basin Research, Volume 38, Issue 4, July–August 2026.
This paper approaches non‐unique inverse problems by generating a representative ensemble of all possible solutions using the concept of symmetry. In the context of basin modelling, a symmetry is any manipulation of a forward model's parameters (e.g., thermal history) that leaves the model output (e.g., downhole vitrinite reflectance) unchanged ...
