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.

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 ...
