Late Quaternary pollen record from southwest Seward Peninsula, western Alaska, and the vegetation history of central Beringia

open access: yesArctic, Antarctic, and Alpine Research
Pollen analysis of samples from a coastal exposure near Teller, southwestern Seward Peninsula, Alaska, provides a record of vegetation and climate spanning the Last Glacial Maximum (LGM) through the Holocene.

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 ...

Paleopedology as a Tool for Reconstructing Paleoenvironments and Paleoecology

open access: yes, 2018
Soils form as a product of physical, chemical, and biological activity at the outermost veneer of Earth’s surface. Once buried and incorporated into the sedimentary record, these soils, now paleosols, preserve archives of ancient climates, ecosystems ...

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Taphonomy, geology, and paleoecology of the Sandy Site, an exceptional assemblage in the Maastrichtian Hell Creek Formation of South Dakota

open access: yes, 2004
The Sandy Site is a multispecific terrestrial deposit in the fluvial sediments of the Upper Cretaceous Hell Creek Formation. It captures a diversity of Late Cretaceous dinosaurs and other vertebrates.

Origins Under the Blowtorch: Frequent Fire Shifts the Balance Between Sunda‐Origin and Sahul‐Origin Plant Species in a Tropical Savanna

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We examined the effect of fire frequency on the composition of vegetation of different biogeographic origins, to understand how frequently an ecosystem can be subject to fire but still retain its evolutionary diversity. There was dramatic structural and biogeographic change in less than 20 years from dry tropical woodlands into savannas, creating ...

The effects of the Richmondian invasion on benthic invertebrate functional diversity during the Late Ordovician

open access: yesFrontiers in Ecology and Evolution
Rising temperatures and globalization are enabling widespread biotic invasions today, particularly in marine environments. While the long-term consequences of invasion are poorly understood, the fossil record can be used to assess the impacts of past ...
