The Phytoliths in the Flora of Ecuador project: Perspectives on phytolith classification, identification, and establishing regional phytolith databases [PDF]

open access: yesJournal of Archaeological Science, 2016
Abstract The Phytoliths in the Flora of Ecuador project was undertaken to establish diagnostic phytolith types and phytolith vegetation signatures to enhance archaeological and paleoenvironmental phytolith applications in the region. In this paper I discuss the “products” of this research, and provide links to on-line resources.

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.

Geoarchaeological and Paleoenvironmental context of the human settlement in the Eastern Tandilia Range, Argentina [PDF]

open access: yes, 2013
The Tandilia range is a discontinuous series of hills and valleys located at the central area of the Pampean region (Argentina). The process of human settlement reached in this zone the highest population densities and reoccupation levels of Southern ...

Phytoliths of pteridophytes

open access: yesSouth African Journal of Botany, 2011
AbstractStudy of phytoliths of pteridophytes is an emerging area of research. Literature on this aspect is limited but increasing. Some recent findings have shown that phytoliths may have systematic and phylogenetic utility in pteridophytes. Phytoliths are functionally significant for the development and survival of pteridophytes. Experiments with some

Pacific Bananas: Complex Origins, Multiple Dispersals? [PDF]

open access: yes, 2008
This paper reviews recent genetic evidence for the origins of the traditional cultivated bananas of the Pacific, and shows that they are unexpectedly complex. Current assumption of their prevailing west-to-east spread from Southeast Asia into the Pacific

Quantifiable differences between phytolith assemblages detected at species level: analysis of the leaves of nine Poa species (Poaceae)

open access: yesActa Societatis Botanicorum Poloniae, 2015
The taxonomic value of phytolith assemblages and their degree of variability within different species of the same genus is still an undervalued issue in the botanical range of phytolith studies.

Phenotypic and Molecular Characterisation of Silicon Uptake and Deposition in Festuca arundinacea [PDF]

open access: yes, 2017
Silicon (Si) is taken up from the soil as monosilicilic acid by plant roots, transported to leaves and deposited as phytoliths, amorphous silica (SiO2) bodies, which are a key component of anti-herbivore defense in grasses. Silicon transporters have been

Assessing phytolith preservation in a Late Quaternary loess-paleosol sequence from the Kashmir Valley, Northwest Himalaya, India

open access: yesQuaternary Science Advances
Phytolith content and its preservation in soils form a robust tool for paleoecological reconstruction. Post-depositional processes, however, influence the preservation of phytolith assemblages in soils thus making the paleoecological inferences biased ...
