How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Conference abstract: Morphometry is increasingly used in phytolith analysis. It is regularly applied to distinguish between phytoliths from closely related taxa, particularly to differentiate and identify crop plants, but also to study grass paleoecology and evolution, for example. Open source morphometric software based on drawing masks of phytoli...
The authors present preliminary results from a new research project based in Jebel Shaqadud, Sudan. Their findings highlight the potential for this region's archaeological record to expand our understanding of the adaptation strategies used by human groups in arid north-east African environments away from rivers and lakes during the Holocene. Furth...
Presentation of an small ongoing project carried out under auspices of the International Committee for Phytolith Morphometrics (ICPM). The project is supported by the Hugo de Vries fund, the Netherlands, and Moesgaard Museum.
Perennial herbaceous species form their above‐ground parts every year anew and discard them before the advent of winter. The senescence of above‐ground structures is thus an inevitable part of their life cycle. This is also a key process that determines photosynthetic gain late in the season and the economy of soil‐borne nutrients. Here we address...
Background and aims Grass silica short cell (GSSC) phytoliths appear to be the most reliable source of fossil evidence for tracking the evolutionary history and paleoecology of grasses. In recent years, modern techniques that quantitatively assess phytolith shape variation have widened opportunities for the classification of grass fossil phytoliths...

Background and aims: The relative contributions of inter- and intraspecific variation in phytolith shape and size have only been investigated in a limited number of studies. However, a detailed understanding of phytolith variation patterns among populations or even within a single plant specimen is of key importance for the correct taxonomic ident...
Phytoliths are precipitated in plant tissues when monosilicic acid (H4SiO4) from soil water is taken up by roots. After being released from decaying plant material, phytoliths persist in broad spectrum of sedimentary environments and due to their taxonomic linkages represent valuable tool in paleoecology and archeology. Phytolith analysis based on...
