The onset of grasses in the Amazon drainage basin, evidence from the fossil record [PDF]

open access: yes, 2020
Poaceae (the grass family) originated in the Cretaceous, but first dominate the palynological records of the Amazon drainage basin (ADB) in the Neogene (23 to 2.5 million years ago (Ma)).

Experimental demonstration of the antiherbivore effects of silica in grasses: impacts on foliage digestibility and vole growth rates [PDF]

open access: yes, 2006
The impact of plant-based factors on the population dynamics of mammalian herbivores has been the subject of much debate in ecology, but the role of antiherbivore defences in grasses has received relatively little attention.

Phytolith data in peat profile over the past 1300 years in the Xishan Mountains, Jiangxi Province, China

open access: yesData in Brief, 2019
Phytoliths are microscopic siliceous particles formed in the plants and preserved in the sediments after the plant death and decay. Phytolith formation is controlled by the plant genes and growing environments.

The byre's tale : farming nutrient-poor cover sands at the edge of the Roman Empire [PDF]

open access: yes, 2019
Prior to the construction of a highABSTRACT-speed railway track (TGV) between Antwerp (Belgium) and the Dutch border, archaeological and geoarchaeological research was conducted at several archaeological sites. All are situated in the northern Campine, a

Phytolith Formation in Plants: From Soil to Cell

open access: yesPlants, 2019
Silica is deposited extra- and intracellularly in plants in solid form, as phytoliths. Phytoliths have emerged as accepted taxonomic tools and proxies for reconstructing ancient flora, agricultural economies, environment, and climate.

Grasses and the resource availability hypothesis: the importance of silica-based defences [PDF]

open access: yes, 2007
The resource availability hypothesis (RAH) predicts that allocation of resources to anti-herbivore defences differs between species according to their growth rate.

Phytoliths can cause tooth wear [PDF]

open access: yesJournal of The Royal Society Interface, 2020
Comparative laboratory sliding wear tests on extracted human molar teeth in artificial saliva with third-body particulates demonstrate that phytoliths can be as effective as silica grit in the abrasion of enamel. A pin-on-disc wear testing configuration is employed, with an extracted molar cusp as a pin on a hard disc antagonist, under loading ...

The role of mineral phases in the biogas production technology [PDF]

open access: yes, 2018
In the field of electric power industry, renewable energy sources, fertilisers, reclamation, and waste management, biomass is widely studied and used.

Understanding Fossil Phytolith Preservation: The Role of Partial Dissolution in Paleoecology and Archaeology [PDF]

open access: yes, 2016
Opaline phytoliths are important microfossils used for paleoecological and archaeological reconstructions that are primarily based on relative ratios of specific morphotypes.

Impact of rice cultivar and organ on elemental composition of phytoliths and the release of bio-available silicon

open access: yesFrontiers in Plant Science, 2014
The continental bio-cycling of silicon (Si) plays a key role in global Si cycle and as such partly controls global carbon (C) budget through nutrition of marine and terrestrial biota, accumulation of phytolith-occluded organic carbon (PhytOC) and ...
