Fossil pollen records reveal a late rise of open-habitat ecosystems in Patagonia [PDF]

, 2012
The timing of major turnovers in terrestrial ecosystems of the Cenozoic Era has been largely interpreted from the analysis of the assumed feeding preference of extinct mammals. For example, the expansion of open-habitat ecosystems (grasslands or savannas)

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

Plant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Fire effects on phytolith carbon sequestration

Scientific Reports
Phytolith have been recognized as an important soil bioavailable Si source for plants, as well as a sink of C and heavy metals in soils. Though the impacts of fire and heat on phytolith sequestration of some nutrients (phosphorus, potassium) and heavy ...

Silicon Fertilizer Application Promotes Phytolith Accumulation in Rice Plants

Frontiers in Plant Science, 2019
In this study, a pot experiment was designed to elucidate the effect of varying dosages of silicon (Si) fertilizer application in Si-deficient and enriched paddy soils on rice phytolith and carbon (C) bio-sequestration within phytoliths (PhytOC).

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Geoarchaeological Investigation of Early Neolithic Lagoonal Fringe Landscapes in the Netherlands

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Coastal wetlands have historically been portrayed as too marginal for early crop cultivation during the Mesolithic–Neolithic transition due to their dynamic hydrology, low elevation, and poor drainage. However, growing evidence suggests that these environments played a crucial role in the spread of agriculture. We examined buried and submerged

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]

, 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.

Multiple indicators record human adaptations to climatic change during the Middle Holocene at the Wanbei site in the middle and lower Huai River valley, China

Boreas, Volume 55, Issue 1, Page 150-163, January 2026.
The archaeological sediment sequences analysis from the Wanbei site reveals a predominantly warm and humid climate with a brief cooling phase between 5600 and 5400 a BP, during the Middle Holocene in the middle and lower Huai River valley. Despite the cooling trend, rice remained the dominant crop in mixed farming, while the proportion of millet ...
