Where are the cereals? Contribution of phytolith analysis to the study of subsistence economy at the Trypillia site Maidanetske (ca. 3900-3650 BCE),central Ukraine [PDF]

open access: yes, 2018
Phytolith analysis has been applied in one of the extraordinary Trypillia “mega-site” in central Ukraine. The site Maidanetske, dated to ca. 3900–3650 BCE, is composed of ca. 3000 houses, which were built of earth-based architecture.

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high‐throughput RNA sequencing

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Effects of long-term soil erosion on phytolith assemblages along a catena in a temperate agricultural landscape

open access: yesGeoderma
Agricultural landscapes are exposed to soil erosion by water, wind, and tillage. The erosion-driven lateral translocation of soil has been recognized as a major threat to global soil health and food production.

A review of carbon isotopes of phytoliths: implications for phytolith-occluded carbon sources

open access: yesJournal of Soils and Sediments, 2020
Phytolith-occluded carbon (PhytOC) is mainly derived from the products of photosynthesis, which can be preserved in soils and sediments for hundreds-to-thousands of years due to the resilient nature of the amorphous phytolith silica. Therefore, stable and radioactive carbon (C) isotopes of phytoliths can be effectively utilized in paleoecological and ...

A Millennium of Coastside Occupation. Micromorphological Insights From the Indigenous Site of Las Estacas Cave, Tenerife

open access: yesGeoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The archaeological site of Las Estacas Cave (NW Tenerife, Canary Islands) preserves some of the earliest human occupations in Tenerife, dating to the 2nd century CE, spanning the entire pre‐European time range up to the 15th century. Using soil micromorphology, this study applies a geoarchaeological approach to reconstruct site formation ...
