Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1116-1131, July 2026.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

The new and reinstated genera of agglutinated foraminifera published between 1986 and 1996

open access: yes, 2001
In the 10 years following the publication of "Foraminiferal Genera and their Classification" by Loeblich & Tappan (1987), some 91 new genera of agglutinated foraminifera have been proposed by various authors.

A Roadmap for Using Hybridisation Capture–Based Target Enrichment of Ancient Environmental DNA in Palaeoecology

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

Miocene deep-water agglutinated foraminifera from the Lomonosov Ridge and the opening of the Fram Strait

open access: yes, 2009
Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge.

Eastern Pacific Corals Track Robust ENSO Variability and Stronger La Niña Events 4,000 Years Before Present

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The interannual El Niño‐Southern Oscillation (ENSO) triggers extreme climate events worldwide. Geochemical proxies in coral skeletons from the eastern equatorial Pacific (EP) track ENSO conditions, constraining its long‐term variance and response to forcing.

Mortality, protoplasm decay rate, and reliability of staining techniques to recognise 'living' foraminifera: a review.

open access: yes, 2000
Non-vital staining, especially with rose Bengal, has been widely used in ecological studies to differentiate between the tests of dead(unstained) foraminifera from those presumed to be living at the time of collection (stained).

Recalibration of the Tethyan shallow-benthic zonation across the Paleocene-Eocene boundary: the Egyptian record

open access: yesGeologica 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.

Foraminifera from the Tepetate Formation (Heim) at Las Pocitas, Baja California Sur, Mexico

open access: yesCiencias Marinas, 2008
In order to constrain the age and depositional paleoenvironment of the Tepetate Formation, benthic and planktonic foraminifera were analyzed in samples recovered from an exploration well located at Las Pocitas, Baja California Sur, Mexico.

Commentary: Reframing Massive Carbon Input During the PETM and a Grand 66 Million Year Geoscience Puzzle

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Despite decades of research, hundreds of peer‐reviewed papers, and considerable relevance to Earth's future, the rapid global warming and tremendous CO2 input at the start of the Paleocene‐Eocene Thermal Maximum (PETM) remain highly debated.
