A Universal Phytolith Key

2001
To enable a wider dissemination of phytolith data and to increase the potential of phytolith analysis the need for a comprehensive phytolith classification system which can be used by researchers from a wide range of disciplines is critical and long overdue. A series of papers will describe and illustrate a key based on eight basic disarticulated shape

A review of anatomical and phytolith studies of cystoliths: silica-calcium phytoliths in dicotyledonous angiosperms

Botanical Journal of the Linnean Society, 2023
Abstract Cystoliths are phytoliths of silica and calcium carbonate and are produced in a few groups of dicotyledonous angiosperms. Anatomical and, more recently, phytolith studies have recorded them in different families. In the present review, we analyse and integrate both types of research to compile information about their formation ...

Phytoliths

2006
The study of phytoliths—inorganic silica remnants plants leave behind when they die and decay—has developed dramatically over the last twenty years. New publications have documented a diverse array of phytoliths from many regions around the globe, while new understandings have emerged as to how and why plants produce phytoliths.

Phytoliths in palaeoecology

Geology Today, 2007
With increasing interest in climate change and other issues associated with the history of the environment and anthropogenic evolution there is an ongoing requirement to investigate the Earth's natural systems. A key approach is for scientists to look back into geological time, perhaps millions of years, to see how the world has reacted to natural ...

Grass Phytolith Analysis

Plains Anthropologist, 2005
The vegetative history of eastern North Da kota is broadly known from pollen and multi-proxy investigations of lake basins from across the re gion (Clark et al. 2001; Dean and Schwalb 2000; Wright et al. 2004). These records suggest that parkland or savanna rapidly developed following glacial retreat and subsequent drainage of glacial Lake Agassiz to ...
