Polar Research, 2020 Although the environmental factors influencing the growth rate and reproduction of benthic foraminifera are known, the relationship between foraminifera test size and environmental variables remains unclear, especially on geological timescales.

The Depositional Record, Volume 12, Issue 4, September 2026.An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance
Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.ABSTRACT Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for elucidating ecological processes, yet information on this subject ...

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 ...

Dual clumped isotopes in foraminiferal calcite reveal kinetic bias in some species
Communications Earth & EnvironmentClumped isotope (∆47) analyses of foraminifera provide a powerful means to reconstruct upper and bottom water temperatures, independent of seawater δ18O and elemental composition.

Spatial‐Scale Evolutionary Bias Sheds Light on the Latitudinal Diversity Gradient
Ecology and Evolution, Volume 16, Issue 8, August 2026.Using Escherichia coli as a model species, our experimental findings reveal that populations in high‐fitness‐gain geographic regions undergo rapid expansion, competitively excluding populations from low‐fitness‐gain regions. This results in adaptive evolution that is biased toward areas with higher fitness potential.

Lithostratigraphy and Microbiostratigraphy of the Ruteh Formation in Northwest of Khur, Central Alborz, Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2010 A sequence of Permian rocks crops out in Northwest of Khur in Central Alborz, North of Iran. This sequence consists of the Dorud (Asselian-Sakmarian), Ruteh (Artinskian-Murgabian) and Nesen (Early Djulfian) formations.

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.

Geologica Acta, 2009 The Galala Mountains in Egypt provide an excellent platform-basin transect with deposits spanning the Paleocene/ Eocene (P/E) boundary. These interfingering deposits enable a recalibration between platform and open marine biostratigraphic schemes.
