Phytoliths of pteridophytes

South 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

Opal phytolith and isotopic studies of "Restinga" communities of Maricá, Brazil, as a modern reference for paleobiogeoclimatic reconstruction

Brazilian Journal of Oceanography, 2015
The Maricá restinga, located in the eastern part of the Rio de Janeiro State (Brazil), corresponds to one of the few remaining preserved areas of the state's coastal plain.

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

Acta 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.

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

Quaternary 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 ...

Location, speciation, and quantification of carbon in silica phytoliths using synchrotron scanning transmission X-ray microspectroscopy.

PLoS ONE
Phytoliths of biogenic silica play a vital role in the silicon biogeochemical cycle and occlude a fraction of organic carbon. The location, chemical speciation, and quantification of this carbon within phytoliths have remained elusive due to limited ...

Phytoliths and Taphonomy, the Contribution of Experimentation to the Quantification of Phytoliths in Wood Ashes

Palethnologie, 2010
Ashes, the mineral residues of wood combustion, contain siliceous particles that can be preserved for long periods in archaeological sediments. Phytoliths can thus be useful indicators of combustion activities whose biodegradable or soluble remains have disappeared.In this paper, an experimental evaluation of the potential of phytoliths for the ...
