Soil microbial diversity: The hidden wealth of sustainable farming

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Soil harbors diverse microbial communities that are fundamental to soil health and agricultural sustainability. Despite their ecological and agronomic importance, these communities remain underutilized as biological resources for improving crop production.

AMS 14C dating of Holocene estuarine deposits: consequences of high energy and reworked foraminifera

open access: yes, 2000
Benthic foraminiferal species were used to AMS date Holocene sediments adjacent to trangressive overlap boundaries (TOB) in two high-energy estuaries in northern Spain.

Taxonomy and biostratigraphy of new and emended species of Cenozoic deep-water agglutinated foraminifera from the Labrador and North Seas [PDF]

open access: yes, 1989
Deep marine, fine grained sedimentary strata of Maastrichtian through Miocene age in the Labrador and North Sea sedimentary basins are rich in agglutinated benthic foraminifera.

Disentangling the depositional, tectonic and diagenetic history of a unique case of rhombic calcite in marine carbonate scree‐like deposits in the Cretaceous Cauvery Basin

open access: yesThe Depositional Record, Volume 12, Issue 5, November 2026.
A succession of marine deposited scree deposits got exposed to meteoric fluids due to sea level drop or tectonic uplift. This potentially caused a unique form of diagenetic transformation in scree deposits, that is the formation of micro rhombic calcite.

A tubular protozoan predator: a burrow selectively filled with tubular agglutinated protozoans (Xenophyophorea, Foraminifera) in the abyssal South China Sea [PDF]

open access: yes, 2004
We report the occurrence of an unusual agglutinated protozoan-filled burrow recovered in a box core collected in 1998 from a depth of 2496 m in the South China Sea.

All Different All Equal: High Polymorphism in Nebela (Amoebozoa: Arcellinida) Revealed by Additional Sampling and Barcoding

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Hyalospheniids are a conspicuous group of testate amoebae whose rich morphology has allowed their classification based on the characterization of their shells. However, recent studies showed the occurrence of convergences and phenotypic plasticity, which complicate their taxonomy.

Lithostratigraphy and Microbiostratigraphy of the Ruteh Formation in Northwest of Khur, Central Alborz, Iran [PDF]

open access: yesJournal 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.

Response of deep-water agglutinated foraminifera to dysoxic conditions in the California Borderland basins [PDF]

open access: yes, 1995
Analysis of agglutinated benthic foraminifera from surface samples collected in the San Pedro and Santa Catalina Basins reveals a predictable relationship between the proportions of morphogroups with decreasing bottom water oxygen levels and with the ...

Net Carbon Transfer From Ocean to Land During the Last Deglaciation Synchronous With Sea Level Rise and Lagging Atmospheric CO2 by Several Millennia

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The sequence of events in the global carbon cycle during deglaciations is not entirely understood. Here, we analyze mean ocean δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O in an updated compilation of foraminiferal stable isotope data comprising 902 time series from 381 sediment cores, with individual records covering intervals within the ...

Dual clumped isotopes in foraminiferal calcite reveal kinetic bias in some species

open access: yesCommunications Earth & Environment
Clumped isotope (∆47) analyses of foraminifera provide a powerful means to reconstruct upper and bottom water temperatures, independent of seawater δ18O and elemental composition.
